NQA collaboration configuration example
Network requirements
As shown in Figure 51, configure a static route to Switch C with Switch B as the next hop on Switch
A. Associate the static route, a track entry, and an ICMP echo operation to monitor the state of the
static route.
Figure 51 Network diagram
Configuration procedure
1. Assign each interface an IP address. (Details not shown.)
2. On Switch A, configure a static route, and associate the static route with track entry 1.
<SwitchA> system-view
[SwitchA] ip route-static 10.1.1.2 24 10.2.1.1 track 1
3. On Switch A, configure an ICMP echo operation:
# Create an NQA operation with administrator name admin and operation tag test1.
[SwitchA] nqa entry admin test1
# Configure the NQA operation type as ICMP echo.
[SwitchA-nqa-admin-test1] type icmp-echo
# Configure 10.2.1.1 as the destination IP address.
[SwitchA-nqa-admin-test1-icmp-echo] destination ip 10.2.1.1
# Configure the operation to repeat at an interval of 100 milliseconds.
[SwitchA-nqa-admin-test1-icmp-echo] frequency 100
# Create reaction entry 1. If the number of consecutive probe failures reaches 5, collaboration is
triggered.
[SwitchA-nqa-admin-test1-icmp-echo] reaction 1 checked-element probe-fail
threshold-type consecutive 5 action-type trigger-only
[SwitchA-nqa-admin-test1-icmp-echo] quit
# Start the ICMP operation.
[SwitchA] nqa schedule admin test1 start-time now lifetime forever
