Problem with Fiber connection

[jorge.s]

Hi,

do you ever faced such an issue:

have a Catalyst 6509 with the following module:

4 16 Pure SFM-mode 16 port 1000mb GBIC WS-X6816-GBIC SAL0734KHPN

then I use a Gbic LX to connect to another switch on a remote location, using a fiber 50 micron with around 300meters. On the other side I've a normal 3550 Switch. With this uplink, I get connectivity, and I can ping each other, but no other protocol will work, like for example Telnet will not work.

If in the side of the 6509 Switch I replace by another 3550, using the same Gbic, the connection is immediatly working for all protocols...

I'm getting without answers...

Can you help?

Thanks

Jorge

Hello,

if replacing the switch enables full connectivity, it could be that something in the configuration of both 3550 switches is different. Are the configs exactly identical ?

hi, can u check if there is any ACL's thats blocking those protocols.

[jorge.s]

The configuration on both switches is the most basic you can think about:

interface GigabitEthernet4/10

description upl EDE0104

no ip address

switchport

switchport trunk encapsulation dot1q

switchport mode trunk

!

Looks to me that the Blade it self have some issue, but is strange...

Hi Jorge,

You are able to ping even when you have cat6k so there should not be any problem is data communication or passing of data.

You are not able to telnet as an example can you please confirm if you are running CATOS or IOS?

If IOS can you please post the output from sh run having line vty configs and if you are running CATOS can you post the output of "ip permit list"
