Module: IEEE8021-SPB-MIB
OID (symbolic): IEEE8021-SPB-MIB::ieee8021SpbSysDigestConvention
OID (numeric): 1.3.111.2.802.1.1.26.1.1.9
Node type: OBJECT-TYPE
Type: IEEE8021SpbDigestConvention
Access: read-write
Description: The Agreement Digest convention setting off(=1)/loopFreeBoth(=2)/loopFreeMcastOnly(=3) off => disable agreement digest checking in hellos loopFreeBoth => block unsafe group and individual traffic when digests disagree. loopFreeMcastOnly =>block unsafe group traffic when digests disagree. This object is persistent.
What is ieee8021SpbSysDigestConvention?
Controls how strictly the bridge reacts when its topology agreement digest disagrees with a neighbor's: off(1) disables the check, loopFreeBoth(2) (the default) blocks both unicast and multicast traffic on mismatch, and loopFreeMcastOnly(3) blocks only multicast, a safety knob admins tune when troubleshooting a suspected loop versus wanting maximum loop protection.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.26.1.1.9 snmpwalk -v2c -c public <target> IEEE8021-SPB-MIB::ieee8021SpbSysDigestConvention
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.26.1.1.9.1 snmpget -v2c -c public <target> IEEE8021-SPB-MIB::ieee8021SpbSysDigestConvention.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.111.2.802.1.1.26.1.1.9.1 s <value>
