Configuring VLANs on the Switch
This section describes the commands associated with setting up
VLANs on the switch.
To configuring a VLAN:
1. Create and name the VLAN.
2. Assign an IP address and mask (if applicable) to the VLAN, if
needed.
Note
Each IP address and mask assigned to a VLAN must represent a
unique IP subnet. You cannot configure the same IP subnet on
different VLANs.
3. Assign a VLANid, if any ports in this VLAN will use a tag.
4. Assign one or more ports to the VLAN.
As you add each port to the VLAN, decide if the port will use an
802.1Q tag.
Table 4-2 describes the commands used to configure a VLAN.
Table 4-2
VLAN Configuration Commands
Command Description
create vlan <name> Creates a named VLAN.
create protocol <protocol_name> Creates a user-defined protocol.
enable ignore-stp vlan <name> Enables a VLAN from using STP port information. When
enabled, all virtual ports associated with the VLAN are
in STP forwarding mode. The default setting is
disabled.
config dot1p ethertype <ethertype> Configures an IEEE 802.1Q Ethertype. Use this
command only if you have another switch that
supports 802.1Q, but uses a different Ethertype value
than 8100.
