I could be completely wrong, but shouldn't the second 4200 be the
backup RE and not forced to be a line card?

Could have something to do with it.

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.

Hi Dave,

When you form a VC, the configuration for the second member's interfaces doesn't always get generated - make sure you have

set interfaces ge-1/0/0 unit 0 family ethernet-switching (or whatever port you are testing from) configured

Cheers,

Ben

Change this so the "linecard" is a "backup RE" .. you have to run two
RE's...

Subject: [j-nsp] EX4200 VC Pity Me

Hi all--

Trying to test a VC with two EX4200s running 10.4R9.2. Very simple. I just
can't get the backup (or line card) chassis to pass traffic.
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):
