cpvlanTrunkPortSecondaryVlans2k
Module: CISCO-PRIVATE-VLAN-MIB
OID (symbolic): CISCO-PRIVATE-VLAN-MIB::cpvlanTrunkPortSecondaryVlans2k
OID (numeric): 1.3.6.1.4.1.9.9.173.1.2.4.1.5
Node type: OBJECT-TYPE
Type: VlanIndexBitmap
Access: read-write
Description:
A string of octets containing one bit per VLAN for VLANs with values of 1024 through 2047 in the management domain on this port.
If the VLAN represented by setting a bit to '1' in the bitmap is a secondary VLAN that has already been associated with a primary VLAN, it allows this private VLAN trunk port to remap the secondary VLAN to its primary VLAN for ingress traffic and to remap its associated primary VLAN to the secondary VLAN for egress traffic.
If the bit corresponding to a VLAN is set to '1' and if the corresponding VLAN is a secondary VLAN, then the local system is enabled to transmit and receive frames with proper VLAN remapping via this Private VLAN trunk port.
If the bit corresponding to a VLAN is set to '0', and if the corresponding VLAN is not configured as a normal VLAN, then the system is disabled from sending and receiving frames on that VLAN via this Private VLAN trunk port.
This object is only instantiated on devices which support the range of VLANs up to 4095.
What is cpvlanTrunkPortSecondaryVlans2k?
This object is a bit map representing VLAN IDs 1024-2047, where each bit indicates whether that VLAN is a secondary VLAN allowed on the private VLAN trunk port and how it maps to its primary VLAN. It controls VLAN isolation and traffic forwarding at the second kiloblock range. An operator would configure this to set up private VLAN isolation for specific customer or service tiers on trunk ports.
