SET SPANTREE HELLO_ADDRESS

Use the SET SPANTREE HELLO_ADDRESS command to modify the MAC address which the Bridge Module uses for its spanning tree hello address.

Format

SET SPANTREE HELLO_ADDRESS {MAC address}

Parameters

{MAC address} = XX-XX-XX-XX-XX-XX

Example

OEBM> set spantree hello_address 08-00-8f-10-13-56 [ENTER]

Spanning tree parameters changed

Description

The SET SPANTREE HELLO_ADDRESS command enables you to change the MAC address which the Bridge Module uses for its spanning tree hello address. Modifying the spanning tree hello address enables you to create multiple spanning tree multicast domains.

The MAC address for this command must be entered in the following format:

XX-XX-XX-XX-XX-XX

Note that this address must be a multicast address. Any address other than a multicast address will not be accepted.

Note: Using an address (other than the default spanning tree hello address 01-80-C2-00-00-00) from the IEEE 802.1(d) reserved multicast addresses as the new spantree hello address may cause subsequent network problems in a bridged subnetwork. This is because all IEEE 802.1(d)-compliant bridges in your network will not bridge these IEEE 802.1(d) reserved multicast addresses.
