881
Parameters
None.
Restrictions
Only Administrator, Operator and Power-User level users can issue this command.
Example
To disable VLAN trunking:
DGS-3420-28SC:admin#disable vlan_trunk
Command: disable vlan_trunk
Success.
DGS-3420-28SC:admin#
95-3 config vlan_trunk ports
Description
This command is used to configure a port as a VLAN trunking port. By default, none of the ports is
a VLAN trunking port. A VLAN trunking port and a non-VLAN trunking port cannot be grouped as
an aggregated link. To change the VLAN trunking setting for an aggregated link, the user must
apply the command to the master port. If the command is applied to link aggregation member port
excluding the master, the command will be rejected. Ports with different VLAN configurations are
not allowed to form an aggregated link. However, if they are specified as a VLAN trunking port,
they are allowed to form an aggregated link.
For a VLAN trunking port, the VLANs on which the packets can be by passed will not be
advertised by GVRP on this port. However, since the traffic on these VLANs is forwarded, this
VLAN trunking port should participate in the MSTP instances corresponding to these VLANs.
Format
config vlan_trunk ports [<portlist> | all] | state [enable | disable]
