snFdpCacheIsAggregateVlan
Module: FOUNDRY-SN-SWITCH-GROUP-MIB
OID (symbolic): FOUNDRY-SN-SWITCH-GROUP-MIB::snFdpCacheIsAggregateVlan
OID (numeric): 1.3.6.1.4.1.1991.1.1.3.20.1.2.1.1.11
Node type: OBJECT-TYPE

Description: Neighbor device is in aggregated-vlan.
What is snFdpCacheIsAggregateVlan?
This OID holds a flag (yes/no) indicating whether a neighboring switch discovered via Foundry Discovery Protocol uses aggregate VLAN mode (combines multiple VLANs into one logical group). Reading it tells you the neighbor's VLAN architecture without logging into that device. A network operator would check this when planning VLAN trunks to ensure compatibility—if neighbors use different VLAN modes, some traffic won't pass through correctly.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1991.1.1.3.20.1.2.1.1.11 snmpwalk -v2c -c public <target> FOUNDRY-SN-SWITCH-GROUP-MIB::snFdpCacheIsAggregateVlan
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1991.1.1.3.20.1.2.1.1.11.1 snmpget -v2c -c public <target> FOUNDRY-SN-SWITCH-GROUP-MIB::snFdpCacheIsAggregateVlan.1
