Configuring DR system settings

Configuring the DR system MAC address

Configuration restrictions and guidelines
Changing the DR system MAC address causes DR system split. When you perform this task on a
live network, make sure you are fully aware of its impact.
The DR system MAC address uniquely identifies the DR system on the network. For the DR member
devices to be identified as one DR system, you must configure the same DR system MAC address
on them. As a best practice, use the bridge MAC address of one DR member device as the DR
system MAC address.
Configuration procedure
To configure the DR system MAC address:
Step
1. Enter system view.
2. Configure the DR system
MAC address.
Setting the DR system number
Configuration restrictions and guidelines
Changing the DR system number causes DR system split. When you perform this task on a live
network, make sure you are fully aware of its impact.
You must assign different DR system numbers to the DR member devices in a DR system.
Disabling configuration consistency check
Enabling the short DRCP timeout timer on the IPP or a DR interface
Setting the keepalive hold timer for identifying the cause of IPL down events
