Setting The Dr Keepalive Interval And Timeout Timer; Excluding An Interface From The Shutdown Action By Drni Mad - H3C S6850 Series Configuration Manual

drni keepalive { ip | ipv6 } destination { ipv4-address | ipv6-address }
[ source { ipv4-address | ipv6-address } | udp-port udp-number |
vpn-instance vpn-instance-name ] *
By default, the DR keepalive packet parameters are not configured. If you do not specify a
source IP address or destination UDP port when you execute this command, the IP address of
the outgoing interface and UDP port 6400 are used, respectively.

Setting the DR keepalive interval and timeout timer

About the DR keepalive interval and timeout timer
The device sends keepalive packets at the specified interval to its DR peer. If the device has not
received a keepalive packet from the DR peer before the keepalive timeout timer expires, the device
determines that the keepalive link is down.
Restrictions and guidelines
The local DR keepalive timeout timer must be two times the DR keepalive interval of the peer at
minimum.
Configure the same DR keepalive interval on the DR member devices in the DR system.
Procedure
1. Enter system view.
system-view
2. Set the DR keepalive interval and timeout timer.
drni keepalive interval interval [ timeout timeout ]
By default, the DR keepalive interval is 1000 milliseconds, and the DR keepalive timeout timer
is 5 seconds.
Excluding an interface from the shutdown action
by DRNI MAD
Restrictions and guidelines
Follow these restrictions and guidelines when you exclude interfaces from the MAD shutdown action
by DRNI:
•
For correct keepalive detection, you must exclude the interfaces used for keepalive detection
from the shutdown action by DRNI MAD.
•
If the IPP is a tunnel interface, you must exclude the traffic outgoing interface for the tunnel from
the shutdown action by DRNI MAD.
•
For DR member devices to synchronize ARP entries, you must exclude the VLAN interfaces of
the VLANs to which the DR interfaces and IPPs belong from the shutdown action.
To view interfaces excluded from the MAD shutdown action, see the Excluded ports
(user-configured) field in the output from the display drni mad verbose command.
If you exclude an interface that is already in DRNI MAD DOWN state from the MAD shutdown action,
the interface stays in that state. It will not come up automatically.
Procedure
1. Enter system view.
system-view
2. Exclude an interface from the MAD shutdown action by DRNI.
