stpxPreferredMSTInstancesMap

Module: CISCO-STP-EXTENSIONS-MIB

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

OID (numeric): 1.3.6.1.4.1.9.9.82.1.11.10.1.1

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-write

Description: A string of octets containing one bit per MST instances on this trunk port. The first octet corresponds to MST instances of 0 through 7; the second octet to MST instances 8 through 15; etc. The most significant bit of each octet corresponds to the lowest MST instance value in that octet. The number of bits for this mib object will be determined by the value of stpxMSTMaxInstanceNumber.

For each instance, if it is preferred on this trunk port, then the bit corresponding to that instance is set to '1'.

What is stpxPreferredMSTInstancesMap?

Allows configuring, via a bitmap (one bit per MST instance), which MST instances are preferred on this trunk port.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.82.1.11.10.1.1
snmpwalk -v2c -c public <target> CISCO-STP-EXTENSIONS-MIB::stpxPreferredMSTInstancesMap

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.82.1.11.10.1.1.1
snmpget -v2c -c public <target> CISCO-STP-EXTENSIONS-MIB::stpxPreferredMSTInstancesMap.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.9.9.82.1.11.10.1.1.1 s <value>
