dot1sInstanceVlanMapped
Module: AT-GS950-8-MIB
OID (symbolic): AT-GS950-8-MIB::dot1sInstanceVlanMapped
OID (numeric): 1.3.6.1.4.1.207.1.4.165.118.1.5.1.6
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?
This read-only OID reports which VLANs (IDs 1–1023) are currently mapped to a given MSTP instance, encoded as a bitmask with one bit per VLAN. A set bit indicates that the corresponding VLAN is actively associated with the instance.
