Symptom
HA breaks after uploading new NBAR protocol pack.
Conditions
Loading new NBAR protocol pack
Workaround
Remove new NBAR command from config:
configure terminal
no ip nbar protocol-pack bootflash:pp-adv-c9800-173.1-40-54.0.0.pack
end
Then copy the file to the secondary after the HA comes back up:
copy bootflash:pp-adv-c9800-173.1-40-54.0.0.pack bootflash-2:pp-adv-c9800-173.1-40-54.0.0.pack
Finally re-enable the command:
configure terminal
ip nbar protocol-pack bootflash:pp-adv-c9800-173.1-40-54.0.0.pack
end
Further Problem Description
The issue is that the protocol pack is not copied to the secondary, this causes a config mismatch which breaks HA. Manually copying the file over should resolve the issue.
