stpxPreferredVlansMap2k
Module: CISCO-STP-EXTENSIONS-MIB
OID (symbolic): CISCO-STP-EXTENSIONS-MIB::stpxPreferredVlansMap2k
OID (numeric): 1.3.6.1.4.1.9.9.82.1.2.1.1.2
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description: A string of octets containing one bit per VLAN for VLANS with VlanIndex values of 1024 through 2047 in the management domain on this trunk port. The first octet corresponds to VLANs with VlanIndex values of 1024 through 1031; the second octet to VLANs 1032 through 1039; etc. The most significant bit of each octet corresponds to the lowest value VlanIndex in that octet.
For each VLAN, if it is preferred on this trunk port, then the bit corresponding to that VLAN is set to '1'. The default value is 128 bytes of zeros.
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 VLAN on the trunk port), any SNMP Set operation accessing an instance of this object should also write the value of vlanTrunkPortSetSerialNo.
What is stpxPreferredVlansMap2k?
Read-write bitmap extending stpxPreferredVlansMap to cover VLANs with index 1024-2047, marking which of these VLANs are preferred on this trunk port.
