ctVlanProtoEtherType
Module: CTRON-VLAN-EXTENSIONS-MIB
OID (symbolic): CTRON-VLAN-EXTENSIONS-MIB::ctVlanProtoEtherType
OID (numeric): 1.3.6.1.4.1.52.4.1.2.16.5.3.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This object returns the protocol or Ether type that is mapped to
the VLAN specified in it's instancing. This object takes the
value of any valid Ether type(0x0600..0xFFFF).
In addition to the previously mentioned range of Ether types, the
following values hold special meaning:
Value Description DSAP/SSAP/Control
------- --------------- ----------------------
0x100 LLC_IPX1 0xE0E003
0x101 LLC_IPX2 0xFFFF
0x102 LLC_NETBIOS 0xF0F003
0x103 LLC_BANYAN 0xBCBC03
What is ctVlanProtoEtherType?
The Ethertype or protocol value (0x0600-0xFFFF, plus special legacy codes such as 0x100 for IPX or 0x102 for NetBIOS) that this table row maps to a VLAN for untagged incoming frames -- an admin uses this to, for example, route legacy NetBIOS traffic into its own VLAN automatically.
