5.2 Configure self-healing
The self-healing feature enables associating neighbors to each radio port. In case of failure of a radio port, the
neighbors increase their transmit power to provide coverage and compensate for the failed RP. You can also enable
interference avoidance, which causes radios to change their channel settings to avoid interfering with surrounding
radios.
To enable self-healing:
1. From the Special Features > Self Healing > Configuration tab, check the Enable Neighbor Recovery box, then
click Apply.
2. Then from the Neighbor Details tab click Detect Neighbors.
3. You can now edit an RP radio to check that the other radios with same 802.11 mode (a or b/g) have been
listed as neighbors.
5.3 Test roaming time
You can determine the roaming time by first using the WESM to determine the radio port to which the phone is
associated. To test roaming time:
1. From Device Association > Wireless Stations, note the radio’s Station Index.
2. Go to Device Association > Radio Adoption Statistics and determine the MAC address of the corresponding
radio port.
3. To determine the switch port associated with this MAC address, use ProCurve Manager’s Find Node tool.
o Use the command show lldp info remote all on the switch if the radio ports are connected at layer 2.
o Or use show arp if the radio ports have IP addresses.
4. From a machine on the network launch a ping to the phone IP address: 10.1.40.151.
5. From the switch CLI or Web agent disable the port of the RP to which the phone is associated. The phone
should lose one or two pings, then subsequent pings should be successful again:
