[j-nsp] EX4200 VC Pity Me

[Paul Zugnoni]

Two things:

1. The configuration for interfaces on your member 1 switch has been truncated. Just make sure the config is actually there and similar to the ports you were using to plug in for testing (i.e. that they are in the same vlan, etc. Do you learn mac addresses on member 1 when the pings don't work? Is spanning tree blocking at all?

2. Not sure what the recommendation of the day is on the 2-member VC, but you don't need the no-split-detection if you're explicitly forcing the 2nd unit into a purely line card role; no-split-detection is worthwhile in a 2-unit only config where either member may become master.

Pinging the gateway out of the routing engine or master works fine.  Trying to ping through the backup/line card gives me nothing.  The VC is recognized (per the below).  Something simple I'm doing wrong, I know.  Here's some output (and thanks for any help you might provide):
