H3C S6850 Series Configuration Guide

8
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 number
{ 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 shutdo
wn action by DRNI MAD
5. Configuring a DR interface
6. Specifying a Layer 2 aggregate interface or VXLAN tunnel inte
rface as the IPP
7. (Optional.) Disabling configuration consistency check
Config
uration 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 o
n the IPP or a DR interface
9. (Optional.) Setting the keepalive hold timer for identifying the cau
se of IPL down events
10. Configuring DR system auto-recovery
11. (Optional.) Setting the data restoration interval
