DES-1228/ME Layer 2 Metro Ethernet Switch CLI Reference Manual
Used to configure a port as a VLAN trunk port.
config vlan_trunk ports [<portlist>|all] | state [enable|disable]
This command is used to configure a port as a VLAN trunk port. By default, none of the
ports on the Switch are VLAN trunk ports. A VLAN trunk port and a non-VLAN trunk port
cannot be grouped as an aggregated link. To change the VLAN trunk setting for an
aggregated link, the user must apply the command to the master port. However, this
setting will disappear as the aggregated link is destroyed, and the VLAN trunk setting of
the individual port will follow the original setting of the port.
If the command is applied to link aggregation member port excluding the master, the
command will be rejected.
The ports with different VLAN configurations are not allowed to form an aggregated link.
However, if they are specified as VLAN trunk ports, they are allowed to form an
aggregated link.
For a VLAN trunk port, the VLANs on which the packets can be by passed will not be
advertised by GVRP on that particular port. However, since the traffic on these VLANs are
forwarded, this vlan trunk port should participate the MSTP instances corresponding to
these VLAN.
<portlist> − Specifies the list of ports to be configured.
enable − Specifies that the port is a VLAN trunk port.
disable − Specifies that the port is not a VLAN trunk port.
Only Administrator-level users can issue this command.
