stpxMSTInstanceEditVlansMap

Module: CISCO-STP-EXTENSIONS-MIB

OID (symbolic): CISCO-STP-EXTENSIONS-MIB::stpxMSTInstanceEditVlansMap

OID (numeric): 1.3.6.1.4.1.9.9.82.1.11.9.1.2

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-write

Description: A string of octets containing one bit per VLAN. The first octet corresponds to VLANs with VlanIndex values of 0 through 7; the second octet to VLANs 8 through 15; etc. The most significant bit of each octet corresponds to the lowest value VlanIndex in that octet.

For each VLAN, if it is mapped to this MST instance, then the bit corresponding to that VLAN is set to '1'. Each VLAN can only be mapped to one unique MST instance in the range from 1 to stpxMSTMaxInstanceNumber. If the bit corresponding to a VLAN is changed from '1' to '0', then that VLAN will be automatically mapped to MST instance 0 by the device.

This object is deprecated and replaced by stpxSMSTInstanceEditVlansMap1k2k.

What is stpxMSTInstanceEditVlansMap?

Allows editing, via a VLAN bitmap (VlanIndex 0-7 per bit, etc.), which VLANs are mapped to an MST instance before committing the change.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.82.1.11.9.1.2
snmpwalk -v2c -c public <target> CISCO-STP-EXTENSIONS-MIB::stpxMSTInstanceEditVlansMap

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.82.1.11.9.1.2.1
snmpget -v2c -c public <target> CISCO-STP-EXTENSIONS-MIB::stpxMSTInstanceEditVlansMap.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.9.9.82.1.11.9.1.2.1 s <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> stpxMSTInstanceEditVlansMap.1
