ctVlanSupportedPortNum
Module: CTRON-VLAN-EXTENSIONS-MIB
OID (symbolic): CTRON-VLAN-EXTENSIONS-MIB::ctVlanSupportedPortNum
OID (numeric): 1.3.6.1.4.1.52.4.1.2.16.1.6.1.2
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: The set of ports on the device, specified by ctVlanSupportedSlotNum, that support VLANs. Each octet within the value of this object specifies a set of eight ports, with the first octet specifying ports 1 through 8, the second octet specifying ports 9 through 16, etc. Within each octet, the most significant bit represents the lowest numbered port, and the least significant bit represents the highest numbered port. Thus, each port of the VLAN bridge is represented by a single bit within the value of this object. If that bit has a value of '1' then that port is included in the set of ports; the port is not included if its bit has a value of '0'.
What is ctVlanSupportedPortNum?
A bitmap flagging which ports on the slot (ctVlanSupportedSlotNum) support VLAN tagging at all -- the most significant bit of the first octet covers port 1, and so on; an admin checks this before trying to assign a port to a VLAN to confirm the hardware supports it.
