DCS-3950 series Ethernet switch manual
Function: Configure the type (TPID) of the protocol of switch trunk port.
Parameter: None.
Command mode: Global Mode.
Default: TPID on the port is defaulted at 8100.
Usage Guide: This function is to facilitate internetworking with equipments of other
manufacturers. If the equipment connected with the switch trunk port sends data packet
with a TPID of 9100, the port TPID will be set to 9100, Then switch will receive and
process data packets normally.
Example: Configure the TPID for the switch to be 9100
Switch(Config)#dot1q-tunnel tpid 9100
9.3.3.3 switchport dot1q-tunnel
Command: switchport dot1q-tunnel mode {customer|uplink}
no switchport dot1q-tunnel
Function: Configure the working mode for dot1q tunnel for the port.
Parameters: None.
Command mode: Port Mode.
Default: dot1q tunnel is disabled by default.
Usage Guide: This command can be configured in the port mode when the dot1q- tunnel
is enabled in the global mode. The customer mode is used to allow VLANs from
customers, and should be configured in the access ports. While the uplink mode is used to
connect to operator’s network, and should be configured in the trunk port. For packets
without VLAN IDs coming from the customer ports, upper layer tags will be attached. For
packets with VLAN IDs, outer layer VLAN IDs will be attached. VLAN ID is the ID that the
port belongs to. For packets sent out from the ports in uplink mode, TPID will be attached
as the tag. For packets with double tags, the forwarding will be determined by the MAC
address and outer tags.
Example: Configure the port 1 in VLAN 3 to be in customer mode to connect with
customer’s network, then configure the port 25 to be uplink mode to connect with
operator’s network.
Switch(Config)#vlan 3
