[c-nsp] Ace ft tracking on virtual contexts

[Matlock, Kenneth L]

As in all things, 'it depends' :)
 
If the admin context vlans run across all the exact same hardware, and all settle on the same STP topology, then you're mostly correct. But there are some 'failure' modes that won't get detected, such as
 
- IP address conflicts in a production VLAN in another context
- STP changes/problems in a production VLAN in another context
 
As long as you're ok with not checking for those, then just monitoring the Admin context should be fine. The other question is though, the ACE modules have more than enough horsepower to handle the HA failure detection for all the Contexts, why *wouldn't* you just configure HA to check them? You configure it once and you're done. :)

Hi all.

Is it necessary to track from all virtual context to the peer on a HA setup
Isn't it enough to do it from the admin context ??
