The object to either enable or disable the trunking
protocol for the device. The trunking protocol is used
for negotiating trunk mode and calculating operational
VSANs on an EISL link. It also performs port VSAN
consistency checks. On non-trunking ISL links, if the
port VSANs are different, the E ports will be isolated.
To avoid this isolation, this MIB variable should be
set to 'disable(2)'.
enable(1) - enables trunking protocol.
disable (2) - disables the trunking protocol.
