What is brgState?
This MIB has no DESCRIPTION anywhere, so this reading is inferred from the enumerated INTEGER values and read-only access. It reports the bridge's current operational state: init(0), backup(1), forwarding(2), idle(3), or serial-handshake(4). An admin polls this to confirm the bridge is actually forwarding(2) traffic rather than sitting in backup(1) standby or stuck in serial-handshake(4).
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.86.2.4.5 snmpwalk -v2c -c public <target> NAT::brgState
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.86.2.4.5.1 snmpget -v2c -c public <target> NAT::brgState.1
