chaining switches

[snootalope]

hello

I'm trying to add another switch to a group of switches I already have "chained" together.

I've got three switches currently in the group. One is a 3560 and the other two are 3500's. At the moment, the two 3500's are linked via GBIC's. From one of the 3500's, I've uplinked to the 3560 via one of the FastEthernet ports. That works just fine!

My problem is, i'm trying to add another 3500 switch, but I don't want to use another GBIC, only a FastEthernet port. So, I've configured the new 3500 switch just like the others that are currently in place, but it won't connect, or uplink.

Here's the config from the currently active switchport:

!
interface FastEthernet0/1
switchport trunk encapsulation dot1q
switchport mode trunk
switchport voice vlan 172
!

and the port from the switch I'm trying to add:

!
interface FastEthernet0/13
switchport trunk encapsulation dot1q
switchport mode trunk
switchport voice vlan 172
!

This is the same way I've uplinked them in the past and it's worked just fine.. not sure what i'm doing wrong! both switches are using IOS c3500XL-c3h2s-mz.120-5.3.WC.1

any advice would be great...

Dont forget the nonegotiate command on each port... cisco advise this....

I might be being silly, but did you use a XOVR cable for the uplink from FE to FE?

The only reason some people are still alive, is simply because it's illegal to kill them!! ;0)

The no negotiate command isn't support on the 3500's i'm using.. it is on the 3560, but i'm trying to chain 3500 to 3500.

I've tried both straight and x over cables.. I've always used just straight trough cables though.

i got it.. it was a bad cable. (that i made, oops)
