When a trunk is created with "tmsh create net trunk", with LACP enabled or disabled, the addition of a trunk member may fail. When it fails, there will be log in /var/log/ltm like Jun 3 13:27:15 localhost err bcm56xxd[8763]: 012c0011:3: bs_trunk_addr_set: unit=0 Invalid parameter bs_trunk.cpp(2406) Jun 3 13:27:15 localhost err bcm56xxd[8763]: 012c0011:3: Trouble setting trunk 1, unit 0 bs_trunk.cpp(2591) Jun 3 13:27:15 localhost err bcm56xxd[8763]: 012c0011:3: SDK error Invalid parameter bs_trunk.cpp(2592) Jun 3 13:27:15 localhost err bcm56xxd[8763]: 012c0010:3: Trouble setting trunk: unit=0, trunk=testTrunk bs_trunk.cpp(1886) Jun 3 13:27:15 localhost err bcm56xxd[8763]: 012c0010:3: Trouble adding interface to trunk=testTrunk bsx.c(3109)
A trunk can't be created, and no trunk members can be added.
The problem tends to happen when a trunk is created right after it is deleted. If you wait for over 30 seconds, it is unlikely to happen.
Wait for over 30 seconds before adding back the same trunk.
A fix is already staged, and may show up in a hot fix later.
