358 C HAPTER 14: V IRTUAL LAN S (VLAN S )
Procedure
To modify information for a VLAN, follow these steps:
1 Select the VLAN interface index.
2 For a VLAN other than the default VLAN, enter the VLAN identification
(VID) number.
3 Specify the index numbers of the bridge ports.
4 For a VLAN other than the default VLAN, specify one or more protocol
suites.
If you have selected the IP protocol suite, proceed with step 5. If you did
not define an IP protocol suite for this VLAN, proceed to step 7.
5 Specify whether you want to modify Layer 3 address information ( n or y ).
Since this is the last release to support Layer 3 address information,
specify
n if possible and instead define multiple IP interfaces for this VLAN
using
ip interface define
commands. (See Chapter 16.) If you still
want to modify Layer 3 address information for an IP VLAN:
a Enter y for Layer 3 addressing.
b Enter the Layer 3 network address.
c Enter the Layer 3 subnet mask. To accept the default or current value
in brackets [ ], press Return or Enter.
6 Specify whether you want to modify per-port tagging.
7 If you want to modify per-port tagging, enter the new tag type for the
port (
none
or
802.1Q
).
8 If you have specified that you want to modify more than one port, enter a
tag type for each port.
9 For a VLAN other than the default VLAN, enter a new VLAN name or
keep the current name.
The VLAN name can include up to 32 ASCII characters, including spaces.
If you include spaces, put quotation marks around the VLAN name.
Bridge VLAN Modify Example (9000 Layer 3)
This example shows the steps to modify the per-port tagging for a
protocol-based VLAN on a Layer 3 module. In this example, front-panel
port 5 is changed to have IEEE 802.1Q tagging, and its associated device
is IEEE 802.1Q enabled.
