[c-nsp] VSS VSL Failover Issue

[Sungmin Cho(smcho)]

Team,

 

Our VSL is consist of 2 Interfaces (Te1/5/4, 1/2/8) with VSLP (G1/9/7) as
follows.

 

VSS_BB#show vslp lmp neighbors 

Instance #1:

  LMP neighbors

    Peer Group info:        # Groups: 1         (* => Preferred PG

PG #    MAC             Switch  Ctrl Interface  Interfaces

---------------------------------------------------------------

*1      6c50.4daf.ba00  2       Te1/5/4         Te1/5/4, Te1/2/8

 

If we disconnect one control interface(Te1/5/4) of VSL, we think any
problem doesn’t occur but traffic loss is occurred for 30sec.

(When we disconnect one interface (Te1/2/8) of VSL, any problem didn’t
occur.) 

 

I have no idea this is expected behavior or not ?

 

Thanks for any input in advance
