stpxPreferredVlansMap4k
Module: CISCO-STP-EXTENSIONS-MIB
OID (symbolic): CISCO-STP-EXTENSIONS-MIB::stpxPreferredVlansMap4k
OID (numeric): 1.3.6.1.4.1.9.9.82.1.2.1.1.4
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 3072 through 4095 in the management domain on this trunk port. The first octet corresponds to VLANs with VlanIndex values of 3072 through 3079; the second octet to VLANs 3080 through 3087; 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 stpxPreferredVlansMap4k?
Read-write bitmap extending stpxPreferredVlansMap to cover VLANs with index 3072-4095, marking which of these VLANs are preferred on this trunk port.
