Hi All,
I had two 8320 switch configured in a VSX setup.
This was working wel during the pre-staging fase.
After we deployd the two switches at the customer site, the ISL link won't come up anymore and we see the following message on the
Secondary switch on the ISL ports.
Interface 1/1/52 is down
Admin state is up
State information: Disabled by feature <---------- !!!!!
!
The switches are above each other. We connected the two switches with two DAC cables of 40G. The cable works on other ports so is good.
The Keepalive link is working. i can ping the other 8320 via this link.
!
Its a straight forward config so i'm rather confused .
Can someone help me out with this?
Below the VSX configuration.
!!
