Operation
Command
Restore the default VLAN ID of the hybrid
port to the default value
undo port hybrid pvid
Restore the default VLAN ID of the trunk port
to the default value
undo port trunk pvid
Note that:
z
The Trunk port and isolate-user-vlan cannot be configured simultaneously, while
the hybrid port and isolate-user-vlan can be thus configured. However, if the
default VLAN has been mapped in isolate-user-vlan, you cannot modify the default
VLAN ID until the mapping relationship has been removed.
z
To guarantee the proper packet transmission, the default VLAN ID of local hybrid
port or Trunk port should be identical with that of the hybrid port or Trunk port on
the peer switch.
By default, the VLAN of hybrid port and trunk port is VLAN 1 and that of the access port
is the VLAN to which it belongs.
1.3.9 Set loopback detection for the Ethernet port
The following commands are used for enabling the port loopback detection and setting
detection interval for the external loopback condition of each port. If there is a loopback
port found, the switch will put it under control.
Perform the following configuration in corresponding view.
