<ifname> - Interface name
* local is an internal interface to handle its own IP address.
Usage Examples:

Setting a port to trunk or access
Not all interfaces in the VLAN must be tagged. As traffic from an interface is forwarded
out of the unit, it determines if the destination port requires the frames to be tagged or
untagged.
- A trunk port can receive tagged and untagged frame. A trunk port should use tagged
frame formats for outgoing frames and carries the traffic of multiple VLANs over a
single link.
- An access port can receive only untagged frame. If an access port receives a tagged
frame, the frame is dropped and the source address is not learned. An access port should
use untagged frame formats for outgoing frames. Frames are sent to the port without a
tag. An access port strips the tag from tagged frames and sends it.
By default, all ports are the access ports. To set a specific port to trunk or access, use the
following command.
COMMAND
(conf)# qvlan trunk enable|disable <ifname> [<ifname> ...]
Parameters
enable: sets as the trunk port
disable: sets as the access port
<ifname> - Interface name
* local is an internal interface to handle its own IP address.
Usage Examples:
(conf)# qvlan trunk enable lan
