About WLAN uplink detection
When the uplink of an AC fails, clients cannot access external networks through the APs that are connected to the AC. WLAN uplink detection associates the uplink state of an AC with the radio state of the connected APs. When the uplink fails, the AC disables the radios of the APs. When the uplink recovers, the AC enables the radios of the APs. The association ensures that clients can associate with APs connected to another AC when the uplink of an AC fails.
This feature collaborates with a detection module and the Track module to function.
· When the track entry is in Positive state, the AC enables the radios of the connected APs.
· When the track entry is in Negative state, the AC disables the radios of the connected APs.
· When the track entry is in Invalid state, the AC does not change the radio state of the connected APs.
For more information about the track module, see "Configuring Track."
Restrictions and guidelines: WLAN uplink detection
For the WLAN uplink detection feature to function correctly, configure a detection module to detect the uplink state, and associate a track entry with the detection module. For more information, see "Configuring Track."
Configuring WLAN uplink detection
1. Enter system view.
system-view
2. Associate a track entry with the WLAN uplink detection feature.
wlan uplink track track-entry-number
By default, WLAN uplink detection is not associated with any track entry.
WLAN uplink detection configuration examples
Example: Configuring WLAN uplink detection
Network configuration
As shown in Figure 1, use an NQA operation to test the reachability of each AC's uplink. Configure WLAN uplink detection on each AC so that clients can associate with the AP connected to another AC when the uplink of an AC fails.
Procedure
1. Configure AC 1:
# Create an ICMP echo operation.
<AC1> system-view
[AC1] nqa entry admin test
[AC1-nqa-admin-test] type icmp-echo
# Specify 10.1.1.1 as the destination IP address of ICMP echo requests.
[AC1-nqa-admin-test-icmp-echo] destination ip 10.1.1.1
# Configure the ICMP echo operation to repeat every 1000 milliseconds.
[AC1-nqa-admin-test-icmp-echo] frequency 1000
# Create reaction entry 1. If the number of consecutive probe failures reaches 5, collaboration is triggered.
[AC1-nqa-admin-test-icmp-echo] reaction 1 checked-element probe-fail threshold-type consecutive 5 action-type trigger-only
[AC1-nqa-admin-test-icmp-echo] quit
# Start the ICMP echo operation.
[AC1] nqa schedule admin test start-time now lifetime forever
# Configure track entry 1, and associate it with reaction entry 1 of the NQA operation (with administrator admin and operation tag test).
[AC1] track 1 nqa entry admin test reaction 1
[AC1-track-1] quit
# Associate track entry 1 with WLAN uplink detection.
[AC1] wlan uplink track 1
[AC1] quit
2. Configure AC 2:
# Create an ICMP echo operation.
<AC2> system-view
[AC2] nqa entry admin test
[AC2-nqa-admin-test] type icmp-echo
# Specify 11.1.1.1 as the destination IP address of ICMP echo requests.
[AC2-nqa-admin-test-icmp-echo] destination ip 11.1.1.1
# Create reaction entry 1. If the number of consecutive probe failures reaches 5, collaboration is triggered.
[AC2-nqa-admin-test-icmp-echo] reaction 1 checked-element probe-fail threshold-type consecutive 5 action-type trigger-only
[AC2-nqa-admin-test-icmp-echo] quit
# Start the ICMP echo operation.
[AC2] nqa schedule admin test start-time now lifetime forever
# Configure track entry 1, and associate it with reaction entry 1 of the NQA operation (with administrator admin and operation tag test).
[AC2] track 1 nqa entry admin test reaction 1
# Associate track entry 1 with WLAN uplink detection.
[AC2] wlan uplink track 1
[AC2] quit
Verifying the configuration
This example uses AC 1 to verify the configuration.
1. Verify that the radio state of AP 1 is Up when the state of track entry 1 is Positive:
# Display information about track entry 1.
