jnxMIMstInstanceVlanMapped
Module: JUNIPER-MIMSTP-MIB
OID (symbolic): JUNIPER-MIMSTP-MIB::jnxMIMstInstanceVlanMapped
OID (numeric): 1.3.6.1.4.1.2636.3.46.1.1.5.1.6
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 jnxMIMstInstanceVlanMapped?
A read-only bitmap (up to 128 octets, one bit per VLAN, covering VLAN IDs roughly 1-1024 depending on device support) where a set bit means that VLAN is currently mapped to this spanning tree instance. Admins read this to confirm exactly which VLANs are riding a given MST instance after configuring the mapping.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2636.3.46.1.1.5.1.6 snmpwalk -v2c -c public <target> JUNIPER-MIMSTP-MIB::jnxMIMstInstanceVlanMapped
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2636.3.46.1.1.5.1.6.1 snmpget -v2c -c public <target> JUNIPER-MIMSTP-MIB::jnxMIMstInstanceVlanMapped.1
