[j-nsp] How reliable is EX multichassis? 3300 and 8200

[William McLendon]

NSR was not supported on EX3300s until 12.1 per the release notes, and 12.2 added NSSU for EX3300s.

I did not see mention of NSB in the release notes, but I have to believe it's supported for NSSU to work properly.  Unfortunately I do not have access to any EX3300s to test / confirm.

http://www.juniper.net/techpubs/en_US/release-independent/junos/topics/concept/ex-series-software-features-overview.html#high-availability-features-by-platform-table

also suggests that NSB came in 12.2

also make sure you remove the "no-split-detection" option if your VC is more than 2 units.

my testing with EX4500 / EX4200 VCs has been very positive of the NSR / NSB features on 11.4
