stpxPreferredMISTPInstancesMap

Module: CISCO-STP-EXTENSIONS-MIB

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

OID (numeric): 1.3.6.1.4.1.9.9.82.1.7.5.1.1

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-write

Description: A string of octets containing one bit per MISTP instances in the management domain on this trunk port. The first octet corresponds to MISTP instances with InstIndex values of 1 through 8; the second octet to MISTP instances 9 through 16; etc. The most significant bit of each octet corresponds to the lowest value instanceIndex in that octet. The number of bits for this mib object will be determined by the value of stpxMISTPInstanceNumber.

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

To avoid conflicts between overlapping partial updates by multiple managers, i.e., updates which modify only a portion of an instance of this object (e.g., enable/disable a single instance on the trunk port), any SNMP Set operation accessing an instance of this object should also write the value of vlanTrunkPortSetSerialNo.

What is stpxPreferredMISTPInstancesMap?

Read-write bitmap on a trunk port listing which MISTP instances (numbered 1 upward, one bit each) are preferred for that trunk in the management domain.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.82.1.7.5.1.1
snmpwalk -v2c -c public <target> CISCO-STP-EXTENSIONS-MIB::stpxPreferredMISTPInstancesMap

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.82.1.7.5.1.1.1
snmpget -v2c -c public <target> CISCO-STP-EXTENSIONS-MIB::stpxPreferredMISTPInstancesMap.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.9.9.82.1.7.5.1.1.1 s <value>
