RE: Trunking ISL and 802.1Q on the same Interface [7:74197]
No you don't (have a couple of VLANs, some with ISL and others with 802.1q). The trunking protocol is not an attribute of a VLAN, it is an attribute of a physical (trunking) port. You have some VLANs, put them on whatever trunk port you desire.

RE: Trunking ISl and 802.1q [7:74059]
They are very expensive! I was able to get one through our purchase of an
AVVID solution at work. I got it for training and I can run home and get it
for a hot spare if needed. I was told if I get my CCNP and Voice Specialist
I could have it so...
We did get these at a very good price. CISCO was really pushing to install
the IPCC over the AVAYA 3Com solutions we where looking at. I just hope
we did not jump in over our heads. But anything has to be better then the
old ROLM we had.

RE: Trunking ISl and 802.1q [7:74059]
Hello,
Kind of confused on switch types and trunking.
Do I understand correctly that WS-c2950X can not do ISL?
And that WS-C2912-XL-EN can?
Can 19xx do ISL or 802.1q?
I am going of this link
http://www.cisco.com/en/US/tech/tk389/tk390/technologies_configuration_examp
le09186a00800949fd.shtml
Can some point me to a 1900 link? I can seem to fine a good one. Or
anything else that might help. I like to try and figure this stuff out
instead of being hand feed but I am stumped. Maybe I need to walk away I
have been at it all day. :)
I am trying to finish putting my lab together and need to know to finish
purchasing the switches.
Also how many makes a good lab? Or do I need any more? How many are good to
have for practicing SPT and trunking.
I currently have
1-3550 (this the new PoE type)
1-1912 (enterprise edition)
1- 1201 (not sure if this good for much)
I have the chance to get 2 WS-C2912-XL-EN and am not sure if I need both or
just one.

Re: RES: Problem w/ 802.1q trunking [7:70901]
The native Vlan on the 5500 is Vlan 13. Hemingway: The config I posted was from a 4500M router with a NP-6e module installed. Like I said before I have don't have a problem with 2 of the 3 vlans on the trunk link, but it's Vlan 13 that's the problem. I'm not able to ping from and to anywhere on that Vlan. jvd: I think starting with the release of 12.2 you are able to trunk on 10Mb links on routers 2600 and above. Try it...

RE: TRUNKING MODES [7:70700]
Hi, Mwalie yes, the trunk link can be established even if between different VTP domain, the following is the detailed explaination. A trunk link can be negotiated between two switches only if both switches belong to the same VLAN Trunking Protocol (VTP) management domain. If the two switches are in different VTP domains and trunking is desired between them, the trunk links must be set to on or nonegotiate mode. This setting will force the trunk to be established.

RE: native vlan, trunking question [7:63309]
Native VLAN is the vlan which is is untagged with VLAN information or tags. IE, by default, VLAN 1 is untagged, meaning other devices which do not understand vlan's, can understand traffic from a vlan 1 port (for example).

Re: native vlan, trunking question [7:63309]
A native VLAN is the VLAN that that port uses when trunking breaks down. Thats it. If you don't set it to a specific VLAN in the config, then the native VLAN will be the default vlan. On cisco, this is VLAN 1. Normally, the trunk is up and running and the native vlan doesn't come into play. However, if the trunking goes down for any reason, the port reverts to the native vlan. At that point, only traffic on that vlan/subnet will get through the port. Typicxally, I will set the native vlan of trunking ports to the vlan that I'm using for network management so that I can get to the switch remotely if something goes wrong. Hope this helps, Karen *** REPLY SEPARATOR *** On 2/19/2003 at 2:38 AM supernet wrote: I'm confused on native vlan and trunking.

However, the switch does not accept that command and executing switchport mode ? only show two options, access and multi, not trunk. I'd appreciate anyone letting me in on why I cannot select trunk when it ought to be there. Thank you very much.

However, the switch does not accept that command and executing switchport mode ? only show two options, access and multi, not trunk. I'd appreciate anyone letting me in on why I cannot select trunk when it ought to be there. Thank you very much.

Question on wireless Vlan Trunking BOOTPC issues -Please [7:62628]
I am setting up a wireless bridge and Access point to trunk 2 vlans - One is Vlan 11 ( Voice ), and One is default Vlan 1. Here is the issue. If on vlan 11, (by associated SSID mapped to vlan 11)wireless client (ip phone) gets a ip assigned by dhcp no problem in vlan 11. (dhcp server for the voice vlan subnet sits across the WAN, and AP pipes in through a dot1q trunk port into a 3524 that has a switchport access vlan 11 port piped directly to a 3660 router that only runs the vlan 11 Subnet (10.46.3.0/24). The data vlan 1, and voice vlan 11 ( voice ) were, before this wireless addition 2 flat networks with no intervlan routing, and no trunking involved anywhere in the network. All people in the data vlan 1, pipe into regular switch ports with uplink to a cat 6006, connected to a 3640 that only has main interface routing the vlan 1 layer 3 subnet across the WAN. The dhcp server for data vlan 1 sits on vlan 1 locally(10.44.185.0/21) Issue at hand - If I put my laptop on Vlan 1 using wireless (by associated SSID)and give myself a static ip, I have full connectivity on VLAN 1. (trunking is fine, and both vlans flow through the switch fabric). If I set my laptop to DHCP on SSID VLAN 1, DHCP does not work? Protocol analyzer produces nothing but shows me issuing bootpc requests with no responses. If I pipe directly into the 3524 switch (using switchport access vlan 1) that the Access Point trunks directly into, and use DHCP, I pick up an ip right away, so I have pinned it down to a issue with BOOTPC broadcast going across the Proper broadcast domain (vlan1) when connecting wireless? I think the issue, is because the access point has first associated with the DHCP server reachable Via vlan 11, which existed prior to adding data vlan to the picture of the wireless setup (through helper address on vlan 11's subnet's router), and read that the Cisco 350 access point's do associate with the last DHCP server they contacted, so I increased the timeout on the AP to search for multiple DHCP servers, but to no avail? I realize this is a weird setup, and I did not design, and am only there to make the 2 vlans work and utilize dhcp functionality either from a IP phone, or A pc on the data VLAN using wireless( BY associated SSID ) All criteria has been met, minus DHCP functionality from VLAN 1 ? Has anyone run into this, or something similar? Is there an issue when trunking vlans using wireless using multiple DHCP servers on different VLANS? Any comments or help would be appreciated Note- The customer does not want to intervlan route,and use a single DHCP server with multiple scopes? I discussed this possibility. Thanks!

trunking 10/100 access ports for avaya ip phone [7:62045]
Anyone have any insight on the pro's or con's regarding applying trunks to all 10/100 access ports on a 6509. Presently, I have a cisco voIP environment - using a data vlan and an auxiliary vlan for voice traffic. I've been asked to make an avaya phone work in this environment. Input from Avaya had me make the access port a trunk, make the data vlan the default vlan and apply the aux vlan to the port as well. It does work - my question is in regards to performance and/or design best practices. TIA Robert LEGAL NOTICE Unless expressly stated otherwise, this message is confidential and may be privileged.

Dennis, Just a little different perspective below... dennis cherry wrote: The way we have it is 2 routers connected to the 4000 switch with 4 vlans on the switch. Have set up 4 subinterfaces on each router, 1 for each van. Each with a separate ip address corresponding to the vlan number. We have 2 HSRP groups set up with 2 vlans in each group. That's one way of looking at it. But it might help to keep things clear in your mind if you consider that there really are four HSRP groups. You're simply using each group number (and, as has been pointed out, the same virtual MAC) twice. 1 router will be the active for 1 group (2 of the vlans) and the other router will be the active for the other group (2 vlans). On each subinterface for each router for each vlan, it has a unique virtual HSRP IP address. I originally thought that all would use the same virtual HSRP IP address. Did you mean that all VLANs in a group would use the same virtual address? If so, you really need to consider looking at things the way I described above. Think about it. One VLAN per subnet, right? (yes you can have more than one subnet per VLAN but you can't have more than one VLAN per subnet) So how would a host in VLAN 10 use the virtual IP of VLAN 12 as a gateway (or vice versa)? Even if the VLANs/subnets are in the same group, they're still in different networks. How could a host with ip address 10.1.1.50/24 use a virtual IP of 10.1.2.1/24 as a gateway? The host would need a gateway to reach the gateway since they're in different layer 3 networks. You are saying that there should be 4 groups (1 for each vlan) instead of the 2 groups that we have?? Or is it OK with 2 groups and the 4 unique virtual HSRP IP addresses on each router?? It's OK. But to the extent possible, at least in a real network, I'd think you would want to have a 1:1 ratio between HSRP groups and VLANs. This type of setup wasn't covered together in our class, just vlans and HSRP seperately. But in this lab we have Vlans running thru HSRP router doing ISL trunking and the routers are also running BGP and EIGRP to connect to a remote router. AHHH! Thanks for your help.

RE: hsrp isl trunking [7:57896]
Your instructor is right. We have a pretty big Vlanned network (3000 nodes). The only way for the traffic originating from one subnet to get to another subnet is to go through a router. Therefore, each Vlan (or subnet) needs an individual gateway (router) to get to other subnets. That is why you need a standby HSRP group for each subnet. Side note - Cisco recommends that Vlan correspond to subnets - it is easier to keep track of things. Hope this helps Elwood P.

Re: hsrp isl trunking [7:58144]
Dennis, It's better to have a unique HSRP group for each VLAN. Cisco bases the virtual MAC address on the group. If you reuse the group number, you'll have duplicate MAC addresses. Granted, they're on seperate VLANs and shouldn't matter, but I had a Cat4000 that didn't like it at all, and gave me lots of logged messages about MACs moving around.

hsrp isl trunking [7:57896]
In my Cisco Academy class, we are doing an lab with a lot of different topics rolled into one lab. We have 2 routers set up with hsrp and has a virtual ip address. Now a 4000 switch has 4 vlans configured on it and to use isl trunking to the hsrp routers. These routers have 4 subinterfaces on the fastethernet port going to the switch (one subinterface per vlan on each router). On the 4000 switch we set up a default gateway to the hsrp virtual ip address. But on the hsrp routers when we set up the subinterfaces and enter the standby command for the virtual ip address, I thought that we use the hsrp virtual ip address but the instructor says no. She says we need to put in the vlan number as part of the virtual ip address. Example: subinterface number for vlan 20...Fa0/0.20, ip address...10.200.20.2, standby ip address...10.200.20.1. And for vlan 30 it would be 10.200.30.1 for the virtual ip address. I thought that all subinterfaces would use the same hsrp virtual ip address. I tried to find more info on the Cisco site, but could not. Is this actually correct?? Why would the virtual ip address be different for each vlan??

802.1q trunking [7:57772]
Everyone, Let me explain what I am trying to do. My main building was set up years ago with a Class C address scheme. I need to change this for a number of reasons and am planning to move it to a 10.X.X.X scheme. I would like to do this on a gradual basis. My building contains the following equipment: 7206VXR router that does internal routing. I have one FastEthernet port on this router. One Catalyst 4006 (Sup2, set based code) switch on the third floor. Both these devices run the latest code. The first and second floors have Catalyst 3500 switches with fiber between floors. A VTP domain is set up between the 3 switches. It was suggested to me to put 3 subinterfaces on the fastethernet port on the router and then trunk them to the switch (or switches). I'm not quite sure of the best way to go about doing this. I've read numerous tac articles, but a little more guidance would be greatly appreciated. Here is a sample of the code I used on the 7206 to create the subinterfaces: interface FastEthernet0/0.1 encapsulation dot1Q 111 ip address 10.50.1.1 255.255.255.0 What do I do now?

RE: 802.1q trunking [7:57772]
Is this all 1 flat VLAN now ? If so, read below: If so , and you just want to migrate, I would assign a secondary address to the FE port on the Router that is a 10.x.x.x scheme that you want. This will allow you to have both active and not need to worry about what port that a PC is plugged into. Otherwise, you will be changing the IP of the PC then changing its port VLAN membership on the switch. The method that you are trying will work, but it's a more work then you need to do if your just migrating from one IP name space to the other. If you assign a secondary address to the router, all you will need to do is to change the IP of the PC's and reboot. If your running DHCP, change its scope so it hands out 10.x.x.x address's and as the current leases expire, they will get a new one. Once all the old address space is gone, just go into the router and type the ip address 10.x.x.x.x command without secondary on the end. This will move this IP to the primary address and remove the old address from the router. Tada, your done. If you want to use separate subnets on each floor, then you would need to use sub-interfaces which I am sure others will cover in detail. If not, I will jump back in.

Re: 802.1q trunking [7:57772]
DON'T TRUST THE CODE ON THE 35XX SERIES SWITCHES. Sorry for yelling, but its that important. I've seen repeated situations like this: router switch 1 switch 2 With a daisy chained configuration like this I've seen multiple instances where a vlan that is done correctly on the router won't work on switch 2, even though all the links are set up for trunking. I've tried forcing this situation with allowed vlan configs and so forth, and its just a pain in the you-know-what. It seems less of a hassle with the most recent code, but I never go in and offer a design like that - its just way, way too risky. PA-FE-TX are about $500 on the aftermarket - have them buy you a couple for the 7206, run lines to the switches, and handle each one as an individual connection.

However, if you have only e.g. 2 VLANs and wish to route traffic between them, you can use a router with 2*10 Mbps interface and it will still work.

Hello, Well, the link provided below is really good, I didn4t know it. However, I do have a question: I searched for ISL feature with the router 1750 selected, and it was found, then I repeated the search selecting the router 1751 (since 1750 is discontinued) and it looks there is not ISL support avalaible for this model (there is only 802.1q support). Don4t you think there is probably an error?. Which is the smallest router than can support ISL or 802.1q?

Dear all, I have some problem about MC3810. Two of it connected using Leased Line each side connect to local PBX using E1 R2. Unfortunately MC3810 is not support E1 R2 signalling. So I turn it all into Trunk link. But DSP No. 8 is not up. When I use command show voice dsp all other DSP (No. 1-7) are up with configured encoding. I am also got Clear_Channel encoding for Time Slot 16. In some case when I make configuration to use all 30 Channel. Channel 16 can not established and also all voice call. If I exclude 4 Channel everything work fine. Plese give me your suggession or idea for problem solving. I can't examine wheather DSP fault or not.

VLAN Trunking [7:49976]
G'day all. Got a question regarding VLAN trunking in a switched environment. Say for example, I have a Catalyst 5509 in my network at the core, and then I have lower end catalyst switch's with a gigabit port on each. In this example, lets say I have 14 VLANS to connect, however I only have 8 gigabit ports on my Catalyst 5509. In this case, the customer NEEDS gigabit access back to the core from the distribution layer. My question is, would it be better to: a). Just buy another module of 8 gigabit ports and connect every VLAN's distribution layer back to the Catalyst gigabit ports b). Something else ? Thanks for all your help and time. I appreciate it.

An 802.1q frame size is modified with a 4 byte field that is inserted between the SA and the type or length field. Therefore the max frame size is 1522. The 340 series connect to the lan @ 10BaseT therfore they could not be connected to a trunkport. The 350 series bridges can connect @ 10/100 BaseT therefore they can be connected to a Trunk Port. 802.1q can be carried over access and trunk links. ISL can only be carried over a trunk link. The trunk port on both switches will need to be set to nonegotiate This is assuming you are connecting to a 350 series bridge. The new Saturn ION was launched in New York.

Re: Trunking over Aironet bridge? [7:42833]
Actually, 802.1q adds four bytes, ISL encapsulation makes the frame much larger (by 30 bytes) I so the increase from 1518 to 1522 would make sense for dot1q and an increase from 1518 to 1548 would be needed for ISL (if it's even supported on the 802.11 stuff, but I can't speak on that).

RE: Trunking over Aironet bridge? [7:42833]
An ISL frame can be as big as 1518 + 30 = 1548 bytes. The original frame is encapsulated in a 26-byte header and a 4-byte CRC. An 802.1Q frame can be as big as 1522 bytes. 802.1Q inserts a 4-byte header immediately the destination and source MAC addresses (and source-routing information, if present) of the frame to be transmitted, which could have already been 1518 bytes.

RE: Trunking over Aironet bridge? [7:42833]
I agree. Change the MTU on the bridges. I have a customer with 5 remote sites connected via 802.11b and trunking across all 5 and I have to increase the MTU. What I would love to see is an update to the Aironet code that supports the actual trunking header so my bridge management interfaces could be on a non-native VLAN. I tend to make the native VLAN (Dot1Q) the most active VLAN and not the default VLAN 1. Unfortunately, in this scenario, the bridges won't communicate in VLAN 1 as these frames will be tagged and the bridges don't understand the tags. Maybe some day...

[7:42833] An ISL frame can be as big as 1518 + 30 = 1548 bytes. The original frame is encapsulated in a 26-byte header and a 4-byte CRC. An 802.1Q frame can be as big as 1522 bytes. 802.1Q inserts a 4-byte header immediately the destination and source MAC addresses (and source-routing information, if present) of the frame to be transmitted, which could have already been 1518 bytes.

As far as the radio is concern it will pass the frames out over the wireless. You will need a switch on the other end of the bridge to recieve the frames and break out the vlans. That would be required for ISL, but 802.1q should go with no changes? Marko.

Min. IOS ver./Feature Set to run ISL trunking?? [7:39913]
Hello, The following link (http://www.cisco.com/warp/public/473/50.shtml) states that the min. ios ver and feature set for isl/802.q trunking on a Cisco 2620 is 12.1(5)T and 12.1(5)IP PLUS? Is there any way that it can be done with 12.0.7T or 12.0.5T1IP/IPX feature set? Can someone please confirm this? Thank you. _ Send and receive Hotmail on your mobile device: http://mobile.msn.com Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=39913t=39913 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
RE: ISL Trunking from a h/w's perspective [7:39246]
Answer #1 Sc0 is a virtual port. Think of it as a mini-PC in your switch that provides an address for management functions such as telnet. If you have physical access to your switch then the console port is the easiest way to configure your switch. If Sc0 is configured on the switch and you can connect to a link or port connected to the switch then you can telnet to the switch to configure it. Answer #2 If your question is really something like I have a Cat5K with a Sup III blade that does not have any interface module - how do I configure trunking to this switch? It depends on what other ports exist on the switch. Do a show port capabilities for each module. It will show if the module can be used for ISL trunking. Side note: Sup III interface modules come up on eBay from time to time. -Original Message- From: George Siaw [mailto:[EMAIL PROTECTED]] Sent: Friday, March 22, 2002 5:45 PM To: [EMAIL PROTECTED] Subject: ISL Trunking from a h/w's perspective [7:39246] Guys, Any ideas as how I can configure isl trunking without an Sc0 port on the supervisor engines?

Re: ISL Trunking from a h/w's perspective [7:39246]
described. The information you received from Cisco pertains to ISL trunks, which require a 100mb interface. This was a good discussion. When I took my switching course, three years ago, they were quite adamant that trunking could not be done on a 10 mb interface. Of course, that was before dot1q was available on the routers. If someone took their courses a while back then they probably aren't aware of the changes.

Re: ISL Trunking from a h/w's perspective [7:39246]
Any ideas as how I can configure isl trunking without an Sc0 port on the supervisor engines? Your question is not clear. The SC0 port isn't relevant if you are using trunking to connect two switches. All you have to do is SET TRUNK mod/port ON on both switches and you are done. If you are talking about routing between VLAN's then you need an RSM or a router that is capable of ISL routing (2621 or better).

Re: ISL Trunking from a h/w's perspective [7:39246]
The only time the SC0 interface comes into play is for telnet into the box. If you have any 100 MB ports on your switch, you can run trunking. set trunk (mod/port) on isl If this trunk is running into a router, you need to create the subinterfaces on the router to enable routing between VLANS. int fa1/0.100 ip address (the subnet of the vlan) encap isl (the vlan #) HTH, Scott George Siaw wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

The router's ethernet must be 100 full dux. You configure subinterfaces on the ethernet. a trunking protocol must be configured on each sub with the corresponding vlan #. The router will route between Vlans. Hope this helps. Danny George Siaw wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Thanks for all your responses. One last question though.

Yes, you need to set up the ethernet for 2 sub-interfaces and set the encapsulation to isl and the isl id # to the vlan # you set up on the switch. if the router config is correct the router will route the vlans across the sub-interfaces on the router.

The only time the SC0 interface comes into play is for telnet into the

If you have any 100 MB ports on your switch, you can run trunking.
set trunk (mod/port) on isl
If this trunk is running into a router, you need to create the

I don't know what else you want me to do to prove it. This was true at one
time but
it has changed. I have personally not tried this config and seen it work
but if I have
some time on Monday I'll confirm whether or not the 3660 will do as
advertised.

RE: ISL Trunking from a h/w's perspective [7:39246]
Danny,
Sometimes even people who work for Cisco, even SE's who may by CCIE's, make
mistakes. The router never lies:
3620(config)#int ethernet 0/0.1
3620(config-subif)#encap ?
dot1Q IEEE 802.1Q Virtual LAN
sdeIEEE 802.10 Virtual LAN - Secure Data Exchange
Notice this is an Ethernet, not FastEthernet, and that it does indeed allow
802.1q trunking.
ISL, on the other hand, does require FastEthernet. So maybe that is where
the confusion lies.
Regards,
Kent

Trunking multiple subnets on the same vlan /port [7:34975]
I have 15 different subnets on a eth 0/0 on a 2621 router with 15 secondary addresses . I want to know if it is possible to change them to subinterfaces and trunk more than one subnet accross a 2924 switch and pust more than one subnet in the same vlan/port. That means putting more than one subnet on one port in the same vlan. The subnets could be contiguous. For instance: ip address 64.41.x.241 255.255.255.248 secondary ip address 64.41.x.249 255.255.255.248 secondary Or most are discontiguous. I did not think it could be done but just wanted to throw it out there to see if anyone had a solution.

RE: Trunking multiple subnets on the same vlan /port [7:34975]
Try putting one subnet on each subinterface - each in turn will map to a
vlan. Trunk all the vlans to the switch. On the interfaces where you want
multiple vlans try configuring switchport multi vlan {ADD vlan-list |
REMOVE vlan-list} Valid IDs are from 1 to 1001. Separate nonconsecutive VLAN
IDs with a comma and no spaces; use a hyphen to designate a range of IDs. Do
not enter leading zeros.
Let us know if this works.

Re: VTP Trunking dangerous [7:33097]
I still don't see the need for VTP??? Have given the password thing some thought before but not sure if needed in a smaller star topology type network. There are no other switchblocks. A good stoning sounds awsome to me. As far as bunnies and spanning tree I've made my core switch root bridge for all routable vlans so there are no more recalculations and I don't wonder why the network is out for 50 sec. while STP recalculats. Well it wouldn't take that long in my simple star to calctopology environment (not much to calculate) Mike Sweeney wrote: LOL- you have those nice people too?

Re: VTP Trunking dangerous [7:32957]
Thanks for your input, This is just my thoughts but i'm not entirely convinced that other people in this environment will adhere to policy before dropping in a switch nor have full knowledge of the possible effects and just dump in access switches in the environment with out checking all the necessary vtp settings. As we all know Cisco's default is Server for Trunking. cheers MADMAN wrote: VTP can be very useful in a large switch environment. Yes you can, as with most anything, dick it up, but if your careful, don't install a new switch with the VTP mode set to server in your existing network, you won't have that problem. Dave 416South wrote: Anyone out there using VTP trunking ? I've just been approched by someone in our environment mentioning that they want to use trunking in another switchblock. Correct me if i'm wrong but this means setting up a VTP domain and all. from my understanding this implimentation could be very damaging via bpdu's giving a higher revision # clearing out a core switch config. I've not been a big fan of the VTP and trunking in a medium sized company so far what are your thoughts??? -- David Madland Sr. Network Engineer CCIE# 2016 Qwest Communications Int. Inc.
