What is blcForwardingMode?

Sets the bridge's overall forwarding behavior: filtering (learn and forward based on destination address, the normal mode), transparent (forward every packet regardless of address), or isolated (forward nothing); an admin would use transparent or isolated only for troubleshooting or intentionally cutting off a segment.

snmpget -v2c -c public <target> 1.3.6.1.4.1.43.12.2.1.1
snmpget -v2c -c public <target> LBHUB-BLC-MIB::blcForwardingMode.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.43.12.2.1.1 i <value>
