12.2.3 Restriction of 802.1Q Tunneling
Configuration
The following restrictions apply to configuration of 802.1Q tunneling:
The routing ports cannot be configured as tunnel ports.
The AP port can be configured as a tunnel port.
The 802.1x function cannot be enabled for the port configured as a tunnel port.
Cluster cannot be enabled for the port configured as a tunnel port.
The STP algorithm cannot be added to the port configured as a tunnel port.
GVRP cannot be enabled for the port configured as a tunnel port.
System-guard cannot be enabled for the port configured as a tunnel port.
For DGS-3610 series, it‘s recommended to configure the egress of the user‘s network
to Uplink port, which is connected to the vendor network shown in the Figure 12-1. If
you configured the TPID of the vendor Tag on the 802.1Q tunneling in the user‘s
network, it's required to configure the same TPID of the vendor Tag on the Uplink port.
12.2.4 Configuring an 802.1Q Tunneling
Port
In the global configuration mode, type in interface command to enter the interface
configuration mode. Follow these steps to configure the tunnel port:
The routing port cannot be set as a tunnel port because System-guard,
GVRP, cluster, and 802.1x cannot be enabled and the STP algorithm
cannot be added to the port configured as Tunnel.
The following example demonstrates how to configure a 802.1q Tunneling port:
DGS-3610(config)# interface fastEthernet 0/1
DGS-3610(config-if)# switchport access vlan 22
DGS-3610(config-if)# switchport mode dot1q-tunnel
DGS-3610(config)# end
