Associating Track with Smart Link

Smart Link cannot detect unidirectional links, misconnected fibers, or packet loss on intermediate devices
or network paths of the uplink. It also cannot detect when faults are cleared. To check the link status,
Smart Link ports must use link detection protocols. When a fault is detected or cleared, the link detection
protocols inform Smart Link to switch over the links.

Static routing-Track-NQA collaboration configuration example

Network requirements
As shown in
Switch A is the default gateway of the hosts in subnet 20.1.1.0/24.
•
• Switch D is the default gateway of the hosts in subnet 30.1.1.0/24.
Hosts in the two subnets communicate with each other through static routes.
•
To ensure network availability, configure route backup and static routing-Track-NQA collaboration on
Switch A and Switch D as follows:
On Switch A, assign a higher priority to the static route to 30.1.1.0/24 with Switch B as the next hop.
•
This route is the master route. The static route to 30.1.1.0/24 as the next hop acts as the backup route.
When the master route is unavailable, the backup route takes effect. Switch A forwards packets to
30.1.1.0/24 through Switch C.
On Switch D, assign a higher priority to the static route to 20.1.1.0/24 with Switch B as the next hop.
•
This route is the master route. The static route to 20.1.1.0/24 with Switch C as the next hop acts as
Command
Set the next hop, and associate it with a track
entry:
apply next-hop { ipv6-address [ direct ] [ track
track-entry-number ] }&<1-n>
Figure 30:
"Configuring Smart Link."
Command
display track { track-entry-number | all }
136
Remarks
By default, the next hop
is not specified.
You can configure a
maximum of two next
hops for backup. The
next hop configured
most recently acts as the
backup.
