358CHAPTER 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 ports.

4For 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.

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 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.

6Specify whether you want to modify per-port tagging.

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 port.

9For 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.
