Static Virtual LANs (VLANs)
Configuring VLANs
Creating a New Static VLAN (Port-Based or Protocol-Based)
Changing the VLAN Context Level. The vlan < vid > command operates in
the global configuration context to either configure a static VLAN and/or take
the CLI to the specified VLAN’s context.
Syntax: vlan < vid | ascii-name-string >
[no] vlan < vid >
If < vid > does not exist in the switch, this command creates a
port-based VLAN with the specified < vid >. If the command
does not include options, the CLI moves to the newly created
VLAN context. If you do not specify an optional name, the
switch assigns a name in the default format: VLANn where n
is the < vid > assigned to the VLAN. If the VLAN already exists
and you enter either the vid or the ascii-name-string, the CLI
moves to the specified VLAN’s context.
The [no] form of the command deletes the VLAN as follows:
• If one or more ports belong only to the VLAN to be deleted,
the CLI notifies you that these ports will be moved to the
default VLAN and prompts you to continue the deletion. For
member ports that also belong to another VLAN, there is no
“move” prompt.
[protocol < ipx | ipv4 | ipv6 | arp | appletalk | sna | netbeui >]
Configures a static, protocol VLAN of the specified type. If
multiple protocols are configured in the VLAN, then the [no]
form removes the specified protocol from the VLAN. If a proto-
col VLAN is configured with only one protocol type and you
use the [no] form of this command to remove that protocol, the
switch changes the protocol VLAN to a port-based VLAN if the
VLAN does not have an untagged member port. (If an untagged
member port exists on the protocol VLAN, you must either con-
vert the port to a tagged member or remove the port from the
VLAN before removing the last protocol type from the VLAN.)
Note: If you create an IPv4 protocol VLAN, you must also
assign the ARP protocol option to the VLAN to provide IP
address resolution. Otherwise, IP packets are not deliverable.
A “Caution” message appears in the CLI if you configure IPv4
in protocol VLAN that does not already include the arp protocol
option. The same message appears if you add or delete another
protocol in the same VLAN.
