the cisco 2600's are killin' me :( (interface setup)

i hate these 2600's... they are beatin' the hell outta' me. i've used the 2500's so i'm not used to the slot designations when configuring the interfaces by slot designations.

can someone help me out with dealing with the interface setup.

how do you know which slot the interface belongs to which interface the slot belongs to?

i have a bunch of labs that need to be done using the new lab setup.
 


<< Wierd... I'm used to 2500's as well... You have to setup all your interfaces via slots? How the hell does that work? >>




it's some bs methond like...

interface serial 0/1 or interface serial 0/0 or something.

I don't know how the slash works... is it interface and then slot or the other way around... and how do you determine what's in what slot and what sorta' interface it has.
 
I've never worked on a 2600 yet, but it sound like its just like a 3640 I have at work. The interfaces are all card based.

Configuring the interfaces are pretty much the same as on a 2500 except you have another number to worry about. The x/y breaks down as follows: The x is the card, and the y is the actual interface. If you only have one card with four interfaces it would look like this: Interface 0/0, 0/1, 0/2, 0/3 (0 is the card, 0-3 are the actual interfaces).
 


hmmm... okay here's how the lab 2620 is setup.

It has one wan port... which doesn't seem to be mounted on a card, but this port is still configured by using the "interface fastethernet 0/0" (or something like that...)

The confusion really lies with the dual Serial interfaces. Each interface is a plug in module... so how do I deal with these?

How can I tell which is the slot 1 and which is the slot 2.... and how would I address this?

interface serial 0(the card)/0(interface on that card)
and
inteface serial 1/0?

I guess it would have been easier to see this in action if there were multiple interfaces on the card.
 
look on the back of the router, you should see labels for slot 0 and slot 1. Each interface on the slots is then labeled 0 or 1.

int s0/0
int s0/1
int s1/0
int s1/0

you can also check by typing "show int" at command prompt. Or show run.
 
<Homer's voice>Doh!</Homer's voice> Look at the back of the router. You should be able to see all the cards and which interfaces are included on them.

IIRC, that's not a WAN port. Its the Ethernet interface (10/100) on the 2620.
 
If you do a "show ip interface brief", any cisco router will tell you what it wishes its interfaces to be called. 🙂

give it a try.

I don't have access to config manager... and as for looking at the interface labels... they are non-existant.

I always thought the back of the router was the front because of the way my instructor set the rack...*crickets*... anways

The only designations are on the Serial slots... and they are labled WT0 and WT1 or W0 or W1... I forget.
 
Stay away from config manager, the cli is what yoiu need to work with. Config manager will be no help at all when things go wrong. As well as using "sh ip int brie" to see what interfaces are available just list the config with "wr t" or "show run", these commands will also show you what the router thinks exist in the way of interfaces.

you are SOOOOOOOOOOOOOOOOO the man right now!!!!!!!! This is EXACTLY what I needed. now, I'll have absolutely no problem with these routers.

much gratidute.... 🙂
 
A simple router#show interface would have shown you what interfaces you have...it would not have been hard to figure out from there.
