jnxMIMstInstanceVlanMapped2k
Module: JUNIPER-MIMSTP-MIB
OID (symbolic): JUNIPER-MIMSTP-MIB::jnxMIMstInstanceVlanMapped2k
OID (numeric): 1.3.6.1.4.1.2636.3.46.1.1.5.1.7
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description:
A string of octets containing one bit per VLAN for VLANS with VlanIndex values 1024 through 2047. The first octet corresponds to VLANs with VlanIndex values 1024 through 1031; the second octet to VLANs 1032 through 1039 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'.
This object is only instantiated on devices with support for VlanIndex values up to 4095.
What is jnxMIMstInstanceVlanMapped2k?
This is a bitmap where each bit represents whether a VLAN (1024-2047) is mapped to this spanning tree instance. It shows which VLANs this particular MSTP instance manages. An operator uses this to verify VLAN-to-MST mappings are correct, ensuring redundant links handle the right traffic.
