config double_vlan
Purpose Used to config the parameters for a previously created Q-in-Q VLAN (Double VLAN) on
the Switch.
Syntax
config double_vlan <vlan_name> {[[add [access | uplink] | delete] <portlist> | tpid
<hex 0x0–0xffff>]} (1)
Description This command is used to configure a Q-in-Q VLAN (service provider VLAN) on the
Switch.
Parameters vlan <vlan_name 32> – The name of the Q-in-Q VLAN to be configured. The user is to
enter an alphanumeric string of up to 32 characters to identify this VLAN.
add – Specify this parameter to add ports configured in the <portlist> as one of the two
following types of ports.
• uplink – Add this parameter to configure these ports as uplink ports. Uplink ports
are for connecting Switch VLANs to the Provider VLANs on a remote source.
Only gigabit ports can be configured as uplink ports.
• access – Add this parameter to configure these ports as access ports. Access
ports are for connecting Switch VLANs to customer VLANs.
• portlist – Enter a list of ports to be added to this VLAN. The port list is specified
by listing the lowest switch number and the beginning port number on that switch,
separated by a colon. Then the highest switch number, and the highest port
number of the range (also separated by a colon) are specified. The beginning
and end of the port list range are separated by a dash. For example, 1:3
specifies switch number 1, port 3. 2:4 specifies switch number 2, port 4. 1:3–2:4
specifies all of the ports between switch 1, port 3 and switch 2, port 4 − in
numerical order. Non–contiguous portlist entries are separated by a comma. (ex:
1:1–1:3,1:7–1:9)
delete – Specify this parameter to delete ports configured in the <portlist> from this
VLAN.
• portlist – Enter a list of ports to be deleted from this VLAN. The port list is
specified by listing the lowest switch number and the beginning port number on
that switch, separated by a colon. Then the highest switch number, and the
highest port number of the range (also separated by a colon) are specified. The
beginning and end of the port list range are separated by a dash. For example,
1:3 specifies switch number 1, port 3. 2:4 specifies switch number 2, port 4. 1:3–
2:4 specifies all of the ports between switch 1, port 3 and switch 2, port 4 − in
numerical order. Non–contiguous portlist entries are separated by a comma. (ex:
1:1–1:3,1:7–1:9)
tpid <hex 0x0–0xffff>– The tag protocol ID. This ID, identified here in hex form, will help
identify packets to devices as Q-in-Q VLAN tagged packets. The default setting is
0x8100.
Restrictions Only Administrator and Operator-level users can issue this command.
Users must have the Switch enabled for Q-in-Q VLANs.
Example usage:
To add ports 4 through 8 as access ports to the Q-in-Q VLAN “Tiberius”:
DGS–3426:5#config double_vlan Tiberius add access 1:4–1:8
Command: config double_vlan Tiberius add access 1:4–1:8
Success.
DGS–3426:5#
Example usage:
To delete ports 4 through 8 on the Q-in-Q VLAN “Tiberius”:
