VSL link member is down

[ameya_oke]

Hi,

I have 2 6500 Core switches in VSS configuration.

Redundant VSL links are configured between them in below fashion.

Te1/5/4 of switch1 is connected to Te2/5/4 of switch2 in Portchannel1 which is up.

Te1/5/5 of switch1 is connected to Te2/5/5 of switch2 in Portchannel2 which is down.

My "show interface Te5/5","show int status","sh int te1/5/5 transciever" show SPF is detected but the port is down at both Layer1 and 2

I see light coming from Rx and Tx of SPF modules and cables.

What can be causing this behaviour.

Please let me know if more details is required.

Warm Regards,

Ameya Oke

Switch the fiber pairs around.  Break apart the clip of the fiber pair and reverse the rx and tx fibers.

If you do a show etherchannel summary I assume that the vsl etherchannel is showing (D) on the pair in question ?
