Baystack 470 and cisco 3550

[motox2]

Hello, i am trying to setup a Cisco 3550 because i am short a Baystack 470 switch. I can get into the cisco with no trouble, but i dont have any idea on programming it. Im sure this is workable, i was just hoping someone could give me a little help on setting up the 3550. The cisco is connected to a Baystack via the GBIC port and i cant get any link activity to come up on the cisco, but i get a link light on the baystack. Oh well any help would be appreciated. thx

I havent run across a 470 lately, but I seem to remember that 460 and 470s didn't support autonegotiate on the GBIC port. You could verify that under the port configuration option.

If thats the case, on the Cisco side, go into config mode, int g0/port number and set it to 1000MB. I'm going by memory, but try the below, assuming port 24 is what you are using.

conf t
int g0/24
speed 1000

Hi!, thanks for getting back to me. I really appreciate the help. Just to clarify, i am trying to add a cisco 3550 to an existing network of baystack 470 switches. The 3550 is configured with 2 VLANS, one for the ELAN and one for the TLAN. When i plug in the fiber between the GBIC on the baystack and the GBIC on the 3550, im not getting any link lights on the 3550 GBIC, but my Baystack 470 does show a link. I really wish i didnt have to use the 3550, but this is the only hardware i have. I know the baystack is set correctly because i tested it with another baystack under the same scenario and both the baystacks linked up just fine. The only issue i have is the settings on the 3550 side to get it to talk to the baystack. Thanks again if you have any more info.

Can anybody confirm this configuration? if theres any unnecessary entries, please advise thanks. To sum it up, im trying to trunk a cisco 3550 to a Baystack 470 with the GBIC's. Since the 470 doesnt support autoneg, i was advised to enter the speed and duplex settings, but i was unsure about the switchport entries. thanks again!!

interface Gig 0/1
switchport trunk encap dot1q
