This section describes the commands associated with setting up VLANs
on the switch. Configuring a VLAN involves the following steps:
1 Create and name the VLAN.
2 Assign an IP address and mask (if applicable) to the VLAN, if needed.
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 19
describes the commands used to configure a VLAN.
Description
Creates a named VLAN.
Creates a user-defined protocol.
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.
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.
Configures a protocol filter. Supported
<protocol_type> values include:
etype
llc
snap
The variable <hex_value> is a hexadecimal
number between 0 and FFFF that represents either
the Ethernet protocol type (for EtherType), the
DSAP/SSAP combination (for LLC), or the
SNAP-encoded Ethernet protocol type (for SNAP).
Assigns an IP address and an optional mask to the
VLAN.
