For DRNI to operate correctly, follow these guidelines:
•
Do not configure automatic link aggregation on a DR system.
•
Do not assign DR interfaces or IPPs to a port isolation group. For more information about port
isolation, see "Configuring port isolation."
When you configure a DR interface, follow these restrictions and guidelines:
•
The
link-aggregation selected-port maximum
and
link-aggregation
selected-port minimum
commands do not take effect on a DR interface.
•
If you execute the
display link-aggregation verbose
command for a DR interface,
the displayed system ID contains the DR system MAC address and the DR system priority.
•
If the reference port is a member port of a DR interface, the
display link-aggregation
verbose
command displays the reference port on both DR member devices.
If a DR member device has a large number of MAC address entries, increase its MAC aging time by
using the
mac-address timer aging
command. As a best practice, set the MAC aging time to
be longer than 20 minutes. For more information about the MAC aging time, see "Configuring the
MAC address table."
DRNI tasks at a glance
To configure DRNI, perform the following tasks:
1.
Configuring DR system settings
{
Configuring the DR system MAC address
{
{
Setting the DR system priority
2.
Setting the DR role priority of the device
3.
Configuring DR keepalive settings
{
Configuring DR keepalive packet parameters
{
Setting the DR keepalive interval and timeout timer
4.
Excluding an interface from the shutdown action by DRNI MAD
5.
6.
Specifying a Layer 2 aggregate interface or VXLAN tunnel interface as the IPP
7.
(Optional.)
Disabling configuration consistency check
Configuration consistency check might fail when you upgrade the DR member devices in a DR
system. To prevent the DR system from falsely shutting down DR interfaces, you can
temporarily disable configuration consistency check.
8.
(Optional.)
Enabling the short DRCP timeout timer on the IPP or a DR interface
9.
(Optional.)
Setting the keepalive hold timer for identifying the cause of IPL down events
10.
