358 CHAPTER 14: VIRTUAL LANS (VLANS)
Procedure
To modify information for a VLAN, follow these steps:
1Select the VLAN interface index.
2For a VLAN other than the default VLAN, enter the VLAN identification
(VID) number.
3Specify the index numbers of the bridge po rts.
4For a VLAN other than the default VLAN , specify one or more protocol
suites.
If you have selected the IP protocol suite, proceed wi th step 5. If you did
not define an IP protocol suite for this VLAN, proceed to step 7.
5Specify 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 defi ne commands. (See Chapter 16.) If you still
want to modify Lay er 3 address informa tion for an IP VLAN:
aEnter y for Layer 3 addressing.
bEnter the Layer 3 network address.
cEnter the Layer 3 subnet mask. To accept the default or current value
in brackets [], press Return or Enter.
6Specify whether you want to modify per-port tagg ing.
7If you want to modify per-port tagging, enter the new tag type for the
port (none or 802.1Q).
8If you have specified that you want to modify more than one port, enter a
tag type for each p ort.
9For a VLAN other than the default VLAN, e nter a new VLAN name or
keep the current name.
The VLAN name can include up to 32 ASCI I 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 t his example, front-panel
port 5 is changed to have IEEE 802.1Q tagg ing, and its associated device
is IEEE 802.1Q enabled.
