VIC-2FXS pinout Issue [7:42816]
All, I am trying to get BOTH ports on a VIC-2FXS card working at the same time. I Understand that the wrong combinations of pinout can cause the 2nd port to be shutdown OK so I looked at cco and have tried the following pinouts for a cable between the phone and the VIC-2FXS ports. 1) Only pins 3 & 4 2) Only pins 2 & 5 3) All pins So Pins 3 & 4 simply doesn't work although it's meant to be a single line pinout So to pins 2 & 5, pick the phone up and you get dial tone, dial a number and it rings in the handset but not at the other phone and Oh yeah , the 2nd port is in use So all pins next, both phones ring and get answered, but 2nd port is shutdown, and when you dial you can hear the ring tone BUT also the engaged tone. Anyone have any ideas Regards Richard Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=42816&t=42816 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: Question about Multi-Channel T1/PRI [7:42825]
Sorry about that I did not mean to submit the last message. Here is what I meant to send. I have two 4 port Multi-Channel T1/PRI modules inserted in a VIPS2-40 module and had a question about these modules. Can these ports be used for a fractional T1 as well as a PR ISDN? I found a document on Cisco's web site for a Multichannel DS1/PRI port adapters and it looks like the port adapters I have are the PA-MC-4T1(=) adapters. If I am reading the document correctly it looks like it can be used as a full T1 or fractional T1 as well as a PRI. Am I reading this correctly the documentation is not exactly clear to me.

yes, you must change the default frame size on the ethernet side of both bridges to 1522 (default 1518). As far as the radio is concern it will pass the frames out over the wireless.

BGP Question [7:42847]
If I look for BGP info on an IP using one of the Looking Glass sites (specifically Mae-East) does the number of entries returned mean anything? I have noticed that sometimes there are five or six entries and sometimes only one or two. The number of upstream connections is two. If only one entry exists, then is BGP broken? For example: BGP routing table entry for 216.91.141.0/24, version 7089796 Paths: (1 available, best #1) Advertised to peer-groups: rr-pop Advertised to non peer-group peers: 198.32.187.122 6347 20068 64.241.88.17 (metric 175301) from 165.117.1.110 (165.117.1.110) Origin IGP, metric 4294967294, localpref 100, valid, internal, best Community: 2548:196 2548:229 2548:666 3706:168 6347:1002 6347:3000 To me that implies that there are no alternate routes, and so no BGP on this route. Also, if there are more than two routes does that mean the routes are better connected? What is the best resource for learning more about BGP?

Re: BGP Question [7:42847]
The number of entries only implies the number of alternate paths available to reach that network. BGP will only use the best path available by default. In your example there is only one path available to that network. This is not indicative of any problems with BGP, only a lack of redundancy to that network. BGP is receiving and advertising this network just fine. Excellent BGP books are Internet Routing Architectures by Sam Halabi and BGP4 Command Reference by William Parkhurst.

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).

in the old days of vlan switching, there was serious discussion of using vlans to separate traffic by protocol. set up ports 1,3 and 5 as IP and ports 2,4, and 6 as IPX. More importantly, put all those renegade AppleTalk users on their own VLAN so their traffic doesn't bother people with real work to do ( ;-> ) I don't know if there is serious talk of this any more.

trouble with bridging IPX with one Ethernet and one Serial [7:42861]
Hi, Group, I am having trouble to bridge IPX between Ethernet and Serial interface. R2 in the middle is configured as transparent bridge with IPX routing disabled. All three router running IPX RIP. But R1 and R3 still can not exchange IPX RIP update or IPX ping each other. Someone suggested to configure IRB on R3, put S0 of R3 into bridge group and configure BVI IPX network number to be 700. It does not make much sense to me. When I use two ethernet interface on R2 to bridge traffic, everything works fine. Can someone explain what I am missing if I want to bridge between Ethernet and Serial interfaces.

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.

AppleTalk devices don't broadcast; they multicast, and they don't do that very often. AppleTalk routers and servers don't ever broadcast (or multicast) service announcements like they do in an IPX environment. And the Chooser doesn't broadcast either. A Mac sends a unicast packet to a router when the user pulls up the Chooser. The router figures out which networks are in the zone and forwards the unicast. The recipient routers then multicast. And, no, this doesn't repeat forever at short intervals. Since Mac OX 7.0 (1989) the Mac has backed off on the unicasts it sends to start the process. You knew you would push one of my buttons, didn't you? ;-) As far as IPX traffic, it's not really that bad either, but the SAP broadcasts can get excessive. There are many ways to keep them contained, if that's what the poster had in mind. I think he better give us more info on what he's trying to accomplish. Hopefully he didn't just buy into the BS that "IPX is chatty" (the same BS that you hear about AppleTalk. ;-) You want chatty, watch a Windows machine running NetBIOS and SMB boot!

Re: ways to seperate IP and IPX traffic? [7:42855]
I guess you could do a setup like that However, anymore, virtually any device speaking IPX will also speak IP (i.e. all of our Novell servers run dual stacks IP and IPX as well as all PCs run both IPX and IP and all of our networked printers do both as well) kinda silly, but that's the way most places that run IPX are (they run both)... having said that, it would be nearly impossible (if not impossible) to separate the IP and IPX traffic without the use of a router since a Layer 2 switch would be useless to help do this. Does that sound right? Makes good sense to me, but right now I think anything would.

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...

Okay...at the risk of facing the wrath of Priscilla, here goes. =) Just off the top of my head, why would multicasting be any better than broadcasting in fact, wouldn't that be worst as broadcasts (L2 or L3) are stopped at the router whereas multicast could traverse your entire network, even through routers...? You gotta give me this tho: AppleTalk picks a layer three address at random, then checks to see if it's in use and repeats until it finds one it can use. How lame is that? I was digging thru my CCNA notes from 2+ years ago and read a comment I wrote saying (about it choosing an L3 addr at random) "imagine if that were used on the internet... it could take days/weeks to get an IP address".. =) > You knew you would push one of my buttons, didn't you? ;-) > > As far as IPX traffic, it's not really that bad either, but the SAP > broadcasts can get excessive.

IPX traffic is horrible (admittedly due to Novell, not as a protocol itself per se. also as you pointed out, in all fairness, a large %-age is SAP broadcasts and admittedly, the people whom I inherited the network from didn't do squat to limit any kind of SAP traffic). If you pick a random switchport out of the 28000+ switchports on our network and do a sniffer capture, you'll find probably 75% of it is IPX related... and we use IP for probably 90% of our apps (and web/internet access). that's not acceptable. we cannot wait to get rid of IPX altogether (which will happen when our migration from Netware to 2000 is complete). I'm not a Microsoft zombie, by any means, and I won't even claim that Win2K and Active Directory is any better than Novell NDS, but getting rid of IPX is a godsend no matter if it means running Microslop Win2K that's how much we hate dealing with IPX =) > Hopefully he didn't just buy into the BS that "IPX is chatty" (the same BS > that you hear about AppleTalk. ;-) You want chatty, watch a Windows machine > running NetBIOS and SMB boot! Sounds like sour grapes. LOL (just kidding =) Hey I've seen your website with you @ your I-SCHMAC laptop so it doesn't surprise me to see you defending AppleSquawk... =) Mike W.

Re: What do I need? MC3810 , Please help [7:42849]
FXS is all you'll need for the analog phones. You can do back to back ATM with the T1 module's if you so choose.
