dot1sInstanceVlanMapped
Module: AT-GS950-24-MIB
OID (symbolic): AT-GS950-24-MIB::dot1sInstanceVlanMapped
OID (numeric): 1.3.6.1.4.1.207.1.4.167.118.1.5.1.6
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: A string of octets containing one bit per VLAN. The first octet corresponds to VLANs with VlanIndex values 1 through 8; the second octet to VLANs 9 through 16 etc. The most significant bit of each octet corresponds to the lowest VlanIndex value in that octet.
For each VLAN that is mapped to this MSTP instance, the bit corresponding to that VLAN is set to '1'.
What is dot1sInstanceVlanMapped?
A read-only bitmask showing which VLANs (IDs 1–1023) are currently mapped to a specific MSTP spanning tree instance. Each bit corresponds to a VLAN ID, allowing administrators to see the current VLAN-to-instance assignment.
