DGS-6604 m vlan-tunnel tpid vlan-tunnel tpid Use this command to specify the outer tag TPID at a Network-to-Network Interface (NNI) for the VLAN tunnel application. vlan-tunnel tpid TPID Syntax Description TPID Specifies the TPID for the VLAN tag. The value is in hexadecimal form. Range is 0x0 to 0xFFFF. Default Command Mode Usage Guideline Example 0x88A8 Interface configuration (physical port and port channel interface only). This setting is only available for an NNI port in VLAN tunnel mode. The following shows the TPID usage for the NNI setting: 1. Packet transmitted at an NNI port. a. As a packet is transmitted from an NNI port for VLAN encapsulation, a TPID specified by the vlan-tunnel tpid command is used for the S tag (outer tag) TPID. b. As a packet is transmitted at an NNI port for VLAN remarking (replacement), a TPID specified by the vlan-tunnel tpid command is used for the VLAN tag TPID. 2. Packet received at an NNI port: a. As a packet is received at an NNI port, the TPID specified by the vlantunnel tpid command is used to identify whether or not the packet has an S tag (outer tag). This example shows how to set outer TPID at eth3.12 to 0x9100. Switch(config)#interface eth3.12 Switch(config-if)#vlan-tunnel tpid 0x9100 Verify the settings by entering the show vlan-tunnel command.
