Config Vlan_Trunk - Extreme Networks EAS 200-24p Switch CLI Manual

Chapter 66: VLAN Trunking Command List

config vlan_trunk

Description
This command is used to configure a port as a VLAN trunk port. By default, none of the port is a
VLAN trunk port.
If the user enables the global VLAN trunk function and configure the VLAN trunk ports, then the trunk
port will be member port of all VLANs. That is, if a VLAN is already configured by the user, but the
trunk port is not member port of that VLAN, this trunk port will atutomatically become tagged member
port of that VLAN. If a VLAN is not created yet, the VLAN will be automatically created, and the trunk
port will become tagged member of this VLAN.
When the user disables the VLAN trunk globally, all VLANs automatically created by VLAN Trunk
enabled shall be destroyed, and all the automatically added port membership will be removed.
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 port, 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 this port. However, since the traffic on these VLANs are forwarded, this vlan trunk port
should participate the MSTP instances corresponding to these VLAN.
