What is a3ComSysBridgeLoopDetectSrcAddress?

Reports the source MAC address used to test for loops between client ports (read-only OCTET STRING). This address is used in loop-detection probe frames sent by the bridge. A typical value is an internal system MAC like 00:11:22:33:44:55.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.29.4.10.2.1.22
snmpwalk -v2c -c public <target> A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB::a3ComSysBridgeLoopDetectSrcAddress

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.43.29.4.10.2.1.22.1
snmpget -v2c -c public <target> A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB::a3ComSysBridgeLoopDetectSrcAddress.1
