5-12 C HAPTER 5: V IRTUAL LAN S (VLAN S )
Table 5-1 describes the commands used to configure a VLAN.
VLAN Configuration
Examples
The following example creates a port-based VLAN named accounting,
assigns the IP address 132.15.121.1, and assigns ports 1, 2, 3, and 6 to
it:
create vlan accounting
config accounting ipaddress 132.15.121.1
config accounting add port 1-3,6
Because VLAN names are unique, you do not need to enter the
keyword “vlan” after you have created the unique VLAN name. You
can use the VLAN name alone.
Table 5-1 VLAN Configuration Commands
Command Description
create vlan Allows you to create a named VLAN.
create protocol Allows you to create a user-defined protocol.
config protocol add
Allows you to configure a protocol filter. Supported
protocol types include:
■
EtherType
■
LLC
■
SNAP
config vlan ipaddress
{} Allows you to assign an IP address and an optional
mask to the VLAN.
config vlan [add | delete] port
{tagged | untagged} Allows you to add and delete ports within the
VLAN. You can specify tagged and untagged
port(s). By default, ports are untagged.
config vlan protocol
[ | any] Allows you to configure a protocol-based VLAN. If
the keyword “any” is specified, then it becomes
the default VLAN. All packets that cannot be
classified into other protocol-based VLANs are
assigned to the default VLAN of that port.
config vlan tag Allows you to assign a numerical VLANid. The
valid range is from 1 to 4095.
config dot1p ethertype Allows you to configure an IEEE 802.1Q
EtherType. Use this command if you have another
Switch that supports 802.1Q, but uses a different
EtherType. The default value used by the Switch is
8100.
