Configuring Ifm Tracking - H3C S9500 Series Operation Manual

Operation Manual – VRRP
H3C S9500 Series Routing Switches
Caution:
Before you configure VRRP link monitoring, it is required that no physical loop exists
and the spanning tree protocol (STP) is not enabled on the network.
If all the physical links in between are down, the backup device considers that the
master device is down, and then the backup device switches to the master state. At
this time, two master devices may exist, and you need to ensure communication
through networking.
Make sure that all the links between the master and backup devices are monitored.
Perform the following configuration in VLAN interface view to configure the switch to
monitor a specified link:
Configure the device to
monitor the specified
link
Disable link monitoring
By default, link monitoring is disabled.
Note:
When you configure the device to monitor a specified interface, the interface cannot
belong to any aggregation group (including dynamic aggregation groups).
After you configure the device to monitor an aggregation group, the aggregation
group cannot be removed directly.
You cannot configure the device to monitor multiple links.
After you configure the device to monitor a specified link, you need to use a board
that supports reporting connection failures and configure the link-status hold 0
command globally to meet the performance requirements.

1.2.11 Configuring IFM Tracking

As a special card on softswitch devices, the IP forwarding module (IFM) is the portal of
softswitch, which is used to distribute IP signals. The disconnection with the IFM means
the termination of softswitch; therefore, the reliability of IFM has great importance.
