Command Purpose
[no] interface vlan
vlan-id Creates or deletes a VLAN interface.
31.4.4 Configuring the Super VLAN Interface
The Super Vlan technology provides the following mechanism: hosts that are in different VLANs
but connect the same switch can be distributed to the same IPv4 subnet to use the same default
gateway, and therefore lots of IP addresses are saved. The SuperVLAN technology classifies many
different VLANs into a group, in which these VLANs use a same management interface and the
hosts use a same IPv4 network segment and a same gateway. The VLANs belonging to a
SuperVLAN are called SubVLANs, any of which cannot possess a management interface through
IP configuration.
A SuperVLAN interface can be configured through the command line; the SuperVLAN interface is
configured as follows:
Command Usage Guidelines
[no] interface supervlan
index
Enters the configuration mode of the SuperVLAN interface. If the
designated SuperVLAN interface does not exist, the system will
create the SuperVLAN interface.
The “index” parameter means the index of the SuperVLAN interface,
whose valid value ranges from 1 to 32.
The “no” parameter means to delete the SuperVLAN interface.
[
no
]
subvlan
[setstr] [
add
addstr] [
remove
remstr]
[none]
Configures the SubVlan of the SuperVLAN. The added SubVLAN
does not possess a management interface or belong to other
SuperVLAN. In initial state SuperVLAN does not contain any
SubVLAN. Each time only one subcommand can be used.
The “setstr” parameter means to set the SubVLAN list. For example,
list 2, 4-6 means VLAN2, VLAN4, VLAN5 and VLAN6.
The “add” parameter means to add VLAN lists in the previous
SubVLAN; the “addstr” parameter means the list string, whose format
is the same above.
The “remove” parameter means to delete VLAN lists from the
previous SubVLAN list; the “remstr” parameter means the list string,
whose format is the same above.
The “no” parameter means to delete all SubVLANs of a SuperVLAN.
The “no” subcommand cannot be used together with other
subcommands.
After a SuperVLAN interface is configured, you can configure an IP address for the SuperVLAN
interface; the SuperVLAN interface is also a routing port and any configuration for a port can be
configured on this routing port.
31.4.5 Monitoring the VLAN Configuration and VLAN State
To monitor the configuration and state of VLAN and Dot1Q tunnel, run the following commands in EXEC
