Pre-Configuration Tasks
Before configuring association between interface backup and NQA, complete the following
tasks:

Example
Run the display standby state command to check the status of the NQA test instance and the
backup interface.

NOTE
Assume that the primary and backup links use static routes. When the primary link is faulty, data traffic
will be lost because routes cannot be switched immediately. To speed up data traffic switching, set the
priority of the backup link to be higher than that of the primary link or configure NQA for static routes.
When the NQA test instance detects that the route on the primary link is unreachable, it deletes the static
route corresponding to the primary link from the routing table. For details, see Configuration Guide - IP
Routing.
Configuring routing protocols on the primary link and backup link to ensure connectivity
at the network layer
Configuring an ICMP NQA test instance on the primary link by referring to Configuring
the ICMP Test.
NOTE
Currently, the NQA test instance supports only the ICMP type.
Run:
system-view
The system view is displayed.
(Optional) Run:
ip route-static ip-address { mask | mask-length } { nexthop-address | interface-
type interface-number [ nexthop-address ] } [ preference preference | tag
*
tag ] track nqa admin-name test-name [ description text ]
Association between the IPv4 static route of the primary link and an NQA test instance is
configured or route priorities of the primary and backup links are set.
NOTE
l If the primary and backup links use dynamic routes, skip 2.
l If the primary and backup links use static routes, perform
IPv4 static route of the primary link and an NQA test instance or set route priorities of the primary
and backup links.
Run:
interface interface-type interface-number
The backup interface view is displayed.
Run:
standby track nqa admin-name test-name
Association between interface backup and NQA is configured.
NOTE
A backup interface can associate with only one NQA test instance, while an NQA test instance can
associate with multiple backup interfaces.
