Course Recommendation
Hello all, I have been given the go ahead to attend a one week course of my choice, to be scheduled in May. In the meantime I have been doing home study via books recommended on the groupstudy.com page. I have been doing research and am leaning towards a course offered by globalknowledge; Interconnecting Cisco Network Devices . My background; I have CCNA 1.0 (is it even valid anymore?), but no hands on. I am now in an environment where I must quickly bring myself up to speed on switches, 1900-2800 series, and basic router config. I am particularly interested in V-LAN. Can anyone provide perspective on my choice, or recommend other avenues? I very much want to get the most bang for the buck and be able to apply the knowledge upon course completion. All thoughts, comments, advice greatly appreciated. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Course Recommendation
Thanks for the recommendations. The BCMSN seems the consensus and was also the one I had thought be best for my situation. However, it seems they want ISND as a prerequisite. Perhaps I can contact them and see if my CCNA will suffice. In the month or so prior to the course I can get hands on and bring myself up to speed via study.

Catalyst 2800
Hello all, For study purposes, I've given a Catalyst 2800, with a couple more to follow. The problem is, no one has any idea of the configuration. I don't have a serial cable, though can order one if need be. Can I interface on port 25 for management purposes? Straight or cross-over cable? And where am I to go from there? Do I get a sniffer so I can discover the IP and then telnet or hyperterminal in? Would like to experiment with VLANs but have to get the door open. Any advice greatly appreciated. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Ethernet vs. Fast Ethernet [7:515]
Ok, very basic question, I apologize. I know 10/100 is ethernet/fast ethernet, but what is the compatibility issues? If you have a 10/100 device configured for ethernet (say a 2900xl switch) will it only go at 100 if specifically configured for Fast Ethernet? I can't find any literature that clearly spells the distinctions and considerations.

So configuring for 100 won't cause problems with 10 speed devices?
Guess I should just check it out, but actually I'm thrashing as it is.

PIX Question [7:2061]
Hello all, I am trying to decide which PIX model to purchase; the 520 or the 515. I am bringing in a 256k pipe. The telco is supplying the router, I do not know which model at this point. The PIX will need to be licensed for 150 users max, can go much less if licensing is based on concurrent sessions. I have my quotes but, having no first hand knowledge of the product, I am a little mystified by some of the specs and figures. I will certainly research, and talk to the sales rep, but would like to get some feedback from the experts. While there may be cheaper, and easier (though probably less effective), firewall options, I am looking at this as both a practical and educational purchase. While the 520 chassis is significantly larger than the 515, I cannot discern added hardware or functionality that accounts for the differences. More RAM in the 520, but that doesn't account for the bulk. Can anyone shed light on this? I am also concerned that the 515 must be booted via tftp. I am not comfortable with single options, and in fact have never configured tftp on either end. Though I imagine it isn't too difficult. Some particulars: PIX-515: PIX-515 Chassis only: $1630.00(the "only" does not refer to price) PIX-515, 8x8NBD Svc, Pix-515 Chassis. Add service for S/W Lic: $900.00 Ok, the above is confusing. Is it simply saying the licensing is $900? The mention of the chassis again is what throws me off. And I understand that would be for unlimited users, as that is the only licensing mode for the 515? But then we have: Software license for redundant PIX 515: $326.00 So, does that mean if I'm purchasing the box for a backup role to an existing, I'm getting a deal on the license? PIX-520: PIX 520 Chassis only: $2347.20 PIX 520 8x5xNBD Svc, PIX Firewall 520 Chassis: $1500.00 Now, notice the two lines above could, on first glance, be mistaken as identical to the first two specs for the 515, but they are actually telling me different things. I'm not understanding the distinction. And then I again have the line item "software license for redundant PIX 520". So, I'm a little confused. Could someone take a moment to shed some light on what is being offered, what considerations I should be making related to our needs, any general advice? Oh, and a good book on configuring and working with the PIX box ;-) Thank you! * If you wish to reply via email, please remove spam block from my address.

VLAN's and Routers [7:2534]
Still struggling with VLAN's and a basic question escapes me. If I create: VLAN1 as 10.200.1.x/16 VLAN2 as 10.200.2.x/16 or /24 I get "VLAN's overlap", which I assume is a bad thing (at least at my skill level, I understand you could use overlapped VLAN's). So, I'm confused how I can assign scopes to each VLAN, what the exact rules are. I'm starting to come to the conclusion I cannot use VLAN's without a router. Is that a correct assumption? Any help, tips, leads appreciated.

What I would like to do is create broadcast domains for different
departments, ie finance, admin. But all departments would need to
communicate with the same server(s).
I'd like to implement VLAN's without the expense of having to purchase
routers, but doesn't seem like it's feasible?
I have ordered P. Openheimer's (sp) Top Down Design book and that may
better guide me in trying to implement an efficient network design.

Currently running Banyan IP, am migrating the environment to 2000 and
rebuilding the infrastructure in the process.
I am replacing the 2800 and 1900 switches with Catalyst 2900xl, I

My goal is to simplify management, or centralize may be more accurate,
and make the network as efficient as possible.

Re: VLAN's and Routers [7:2534]
Are dual NIC's feasible? Seems on the surface to be cheaper and more
straightforward but haven't seen it mentioned so I may be missing
something.
I can actually give each department their own server but accessing the

Proposed Network Design [7:10494]
Hello all, We are migrating off of Banyan to Windows 2000 in late July and through August. Concurrent with the migration will be an infrastructure overhaul. I would like to lay out my plans and thoughts; any comments, advice, criticism, improvements, etc. greatly appreciated. I have 95% of my hardware: Dell Poweredge servers: 1550 (6) - file servers 6450 (2) - SQL and Exchange servers 2450 (1) - SQL Cisco Switches: 2948G (1) - distribution switch 2900xl (8) - access switches various numbers of 1900/2800 to be phased out Cisco Aironet Wireless: 2 parabolic, various yaggi and omni antennae a number of workgroup and access bridges, various sizes. The new environment will consist entirely of new servers, no upgrades from old environment. I've taken my first crack at using Visio 2000 to try and lay out a high level conceptualization of my planned design. If interested, please download the diagram: http://www.tuzzy.org/design.zip 200k Currently our network is on one segment and I am creating vlan's. This is an ambitious project for my experience but I'm confident, although I realize it'll take a lot of work and study as I go. I've been researching this scenario for some time now, and have attended a BCMSN week long course with Global Knowledge. So, I may be in dim light but not totally in the dark ;-) Physical Sites consist of: Main site; includes main administrative building and 6 outlying quonset (huts). Fiber from main building to one hut, fiber between huts. Currently in place and operable. Main server room; distribution switch, access switches in main building and physical locations. Heritage site: approx. 4 miles from main. Will connect to Main Site via Aironet, parabolic at Heritage and at Main. Northstar site: approx. 400 yds. from Heritage, connected via fibre, currently in place and operable. Daycare site: approx. 800 yds. from Heritage, will connect via Aironet. Home: approx. 1 mi. from Heritage, will connect via Aironet. All operations must take place within 10.200.x.x range. Our organization is one of three trees within the 2000 forest. Each tree is an independent organization with close ties. One domain per tree. My plans: All servers are Windows 2000, all desktops 2000 Professional. Each VLAN consists of 6 ports on the 2948 switch, each port (as needed) will go to a 2900xl switch for eventual end user access, possible direct 2948 to desktop in some cases. VLAN 1 10.200.1.x / 24 Serving enterprise; Exchange 2000 / Universal file server box ISA (firewall) box Primary DNS, DC, DHCP, Global Catalog VLAN 2 10.200.2.x / 24 File server for info systems, main building. Secondary DNS, DC DHCP? 3 users VLAN 3 10.200.3.x / 24 File server for huts. SQL backend server for online application, access from huts. DHCP? 50 users, web server. VLAN 4 10.200.4.x / 24 One box, 6450, SQL server and file server for finance and services, main building. DHCP? 6 - 12 users, critical data, high resource demand VLAN 5 10.200.5.x / 24 File server for administrative staff, main building. DHCP? 75 users VLAN 6 10.200.6.0 / 24 Spans from main building to heritage center, approx. 4 miles distant. Parabolic and bridge, Aironet, at main building and Heritage center. Bridge on each end connected to a 2900xl switch. File server for Heritage center, possibly daycare. Daycare connected via workstations -> 2900xl -> aironet -> heritage Northstar has own servers, connected to Heritage via fiber. Home will connect to Heritage via wireless (low priority). Possible (probable) second server at Heritage, possible server at Daycare. DNS (cache only), DC, Global Catalog DHCP? 50 users VLAN 7 Not utilized. VLAN 8 Gateway to existing Banyan network. So there we have it. This is actually my first time writing it out in detail and that in itself has been beneficial. If anyone is feeling ambitious and generous I would more than welcome a picking apart of my logic, diagramming, any input at all welcome. I'm sure I have some gaping omissions, leaps of logic or considerations not yet considered. Chances are I'm going overboard with the segmenting? I realize the extra admin chores but think the trade off is tolerable. If you've read this through, I already owe you my thanks ;-) Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=10494&t=10494 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: Proposed Network Design [7:10494]
Sorry if I sounded abrupt, wasn't meant that way.
Fact is, *I* don't see that it'd compromise security, so that doesn't
mean it doesn't in fact make a difference.
My thinking was; if someone could get to my internal network they'd
find that out quick enough.
I appreciate the thought, and if there's room for criticism there,
then that's exactly what I'm looking for.
Constructive criticism is a great learning tool IMO.

That was my intent, to put in as much detail as possible. But it

unreadable. I didn't see that the workspace would "expand" as needed,

The uplinks are already in place and operable, using converters. For
the outlying buildings it's a matter of upgrading the switches,
tidying the mess of cable, and configuring for VLAN.

The two main sites, 4 mi. distance, I have established a direct line
of sight. The other site I'd like to bring into a parabolic is along
the same path, slightly to the west. I figure if I'm lucky the dish
will catch it, if not I have antennae to do the job.
I have yaggis and omnis, I had thought yaggi would be better suited
for distance and direct line. Do you feel the omni is a better option?
Thanks again for your comments, very much appreciated.

Hello all, I'd like to setup a DMZ in the near future and am still pondering purchase of a PIX box. Our interface to the outside world is through a Cisco 1600. So the DMZ would go: 1600 -> PIX -> ? -> ISA box (microsoft proxy/firewall) I know I don't want the PIX talking directly to the ISA, but not too clear what I'm going to put in between, and why (functionality). Our webpages are hosted off site by a third party, I would want to keep my mail server inside right? I would like to set up VPN in the future, should it go through the box between the firewalls? The DMZ doesn't simply double the challenge does it? As in "ok, you got through one firewall, now try the next". Any enlightenment greatly appreciated.

Can't delete Etherchannel? [7:10981]
>From Cisco documentation: Note You cannot delete a Fast Ethernet EtherChannel or Gigabit Ethernet EtherChannel once they are created. This for a 2948G-L3 Once created you can never break it back down to individual ports? That doesn't seem right, and certainly discourages experimentation.

Newbie: running-config/dir/history [7:13322]
Hello all, Am using a 2948G-L3 for learning and eventual implementation, connected via console port.. Have some very basic things escaping me. 1) Core(config-if)#ip address 10.200.0.1 255.255.0.0 Core(config-if)#no shutdown Core(config-if)#end 00:43:41: %SYS-5-CONFIG_I: Configured from console by consolepy 00:43:42: %LINK-3-UPDOWN: Interface FastEthernet1, changed state to up Core#copy running 00:43:45: %LINK-3-UPDOWN: Interface FastEthernet1, changed state to down % Incomplete command. Core#copy running start Destination filename [startup-config]? Building configuration... [OK] Core#dir Directory of bootflash:/ 1 -rw- 3183128 cat2948g-in-mz.120-7.W5.15d.bin Now why do I see only the one file listed above? I've also tried a: copy running start then give it a new name like test.old but won't let me. 2) Core(config)#line con 0 Core(config-line)#history size 50 Core(config-line)#end Core# 00:57:03: %SYS-5-CONFIG_I: Configured from console by console Core#copy running start Destination filename [startup-config]? startup-config Building configuration... [OK] Core#dir / Directory of bootflash:/ 1 -rw- 3183128 cat2948g-in-mz.120-7.W5.15d.bin So seems to me according to the above I should be able to use 'up arrow' to recall commands, and I should see a newer file by dir /all I realize these are quite basic questions, but tolerance for baby steps please. Any enlightment greatly appreciated.

VLAN: ISL or 802.1Q? [7:13325]
I'm not clear on which standard I should use for VLAN setup. I will be using a 2948G-L3 as a core switch. Connected to the core will be a number of 2948xl as access switches. The majority of these access ports will connect directly to end stations, though some will connect to other 2948s (via fiber and via wireless) which then will connect to end stations. Does this last fact mean I must use ISL so as to implement trunking?

Ok, please disregard the "history" question. A reconnect and it's working.

Thanks, my network is indeed all Cisco.
If an environment is ISL, is it a safe assumption one would need to
redo all switches if you started to introduce non-Cisco equipment?
I do have a few 10/100 3Com hubs out there, but I wouldn't think
they'd be affected by either standard?

Re: ISL or 802.1Q? [7:13325]
Thanks for the config sample, and thank you all for the input.
I'm drawn to 802.1Q, although I can't really give exact reasons.
During the transition I will have a few 1900 and a couple of 2800
switches in the network and it seems I'll have less trouble with the
802.1Q.

I love this work ;-)

Hub to Hub through 2600 [7:16328]
Hello, I just received a 2616 router. I set it up through the initial boot screen: SubA - 0/0 10.100.1.1 /16 SubB - 0/1 10.200.1.1 /16 Everything works fine if both interfaces are connected, via straight cable, to a 3Com 10/100 hub. Can ping either interface from either subnet, all machines on each subnet can ping any machine on other subnet. However, when I try to go with two hubs, one for each subnet, I can no longer communicate. Have assured I'm not on uplink, have tried uplink, am sure no problems with hub (new out of box, and working in other configs). If I have both Subs hooked up to one hub, all link lights are green. If I move one of the interfaces to the other hub, no link light. Am I missing something? I'm sure it's something simple but heck if I know. Any help greatly appreciated.

Re: Hub to Hub through 2600 [7:16328]
I have the router interfaces on full/100, perhaps I'll move it to
auto, same as the workstations are.
I have moved equipment, swapped cables, haven't seen anything
suspicous. I lose link lights on the hub and on the router, just
doesn't come back soon's I go to the second hub.
I'm not at the office, but I don't believe the hub has cachine
capability.
I will try putting the interfaces into auto tomorrow, thanks all!

What point to upgrade?
Hi all, At what point, generally speaking, should an office upgrade their network to a router/switch configuration and higher bandwidth? I know there are usage factors involved, but any rough ideas how many machines could efficiently work off of one server and IP with cable internet? Said office would have an internet presence, presumably their own domain and email server. Is the consideration for a router and subnetworks strictly an organizatinal consideration? That is; putting sales on a subnet, marketing on theirs, etc. Any input, or links to network consideration overviews, greatly appreciated.

Re: CCNP and chances of finding a job
Please folks, let's not have this group degenerate into "papers" vs. "hands on" ala the MCSE groups. Of course real world is better, but paper can't hurt either. Thing is not to project oneself as something they are not. I have my CCNA and I readily admit I can't be thrown into the router world. But that paper, along with my admin experience will get me into networking I'm sure. And when I am hired on a network team I am fully prepared to be at the bottom of the ladder doing grunt work again.
