ctVlanProtoEstablish

Module: CTRON-VLAN-EXTENSIONS-MIB

OID (symbolic): CTRON-VLAN-EXTENSIONS-MIB::ctVlanProtoEstablish

OID (numeric): 1.3.6.1.4.1.52.4.1.2.16.5.3.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: A set of the value create(1), causes an entry to be added to the ctVlanProtoAssignTable as specified by the instancing information of ctVlanVID and ctVlanProtoEtherType. This has the result of mapping the specified protocol or Ether type to a VLAN for all received untagged traffic on the ports specified by ctVlanProtoPortList. A set of the value delete(2), causes the specified entry information to be removed from the table. A read of this object will always return create(1).

What is ctVlanProtoEstablish?

Setting create(1) adds a protocol-to-VLAN mapping entry for the Ethertype/VLAN pair given by the row's index, causing matching untagged traffic on the ports in ctVlanProtoPortList to be classified into that VLAN; delete(2) removes the mapping. Reading always returns create(1).

Examples
