vlanTrunkPortVlansActiveSecond2k
Module: CISCO-VTP-MIB
OID (symbolic): CISCO-VTP-MIB::vlanTrunkPortVlansActiveSecond2k
OID (numeric): 1.3.6.1.4.1.9.9.46.1.6.1.1.31
Node type: OBJECT-TYPE
Type: Cisco2KVlanList
Access: read-only
Description: A string of octets containing one bit per VLAN with VlanIndex values of 2048 through 4095.
If the bit corresponding to a VLAN is set to 1, it indicates that vlan is allowed and active in management domain.
If the bit corresponding to a VLAN is set to 0, it indicates that vlan is not allowed or not active in management domain.
What is vlanTrunkPortVlansActiveSecond2k?
This read-only bitmap reports, one bit per VLAN, which VLANs in the 2048-through-4095 range are both allowed and currently active in this trunk port's management domain, complementing vlanTrunkPortVlansActiveFirst2k for the lower range. An administrator uses this to confirm which higher-numbered VLANs are genuinely live on a given trunk. For example, a higher-range VLAN reported inactive here despite being provisioned points the admin toward checking VTP pruning or domain membership settings for that VLAN.
