Network Self Healing
Make one of two choices:
• Click the OK button, and import the file despite the conflict. The module
retains all of its already-configured ACLs. However, any non-conflicting
ACLs are imported normally.
• Click the Cancel button, and cancel the import. The module retails all of its
already-configured ACLs, and no new ACLs are saved to the module. You
can fix the problem in one of two ways:
– If you want your Wireless Edge Services zl Module to keep its current
ACLs, but also to receive all of the imported ACLs, edit the .cvs file.
Change the index numbers so that they no longer conflict with those on
the module.
Then re-import the file, as described in “Importing MAC Standard
ACLs” on page 12-84.
– If you want the ACLs in the imported file to override already-config-
ured ACLs, you must delete these ACLs from your Wireless Edge
Services zl Module.
In Security > MAC Filters screen, select the ACLs that conflict with
imported ACLs. Click the Delete button.
Then re-import the file, as described in “Importing MAC Standard
ACLs” on page 12-84.
Network Self Healing
Self healing keeps your wireless network functioning optimally in response to
changing conditions. A radio in a self-healing network can automatically change the
properties of its RF network, which include:
■ channel
■ transmit power
■ supported rates
By managing this ability, the Wireless Edge Services zl Module provides two basic
services:
■ Neighbor recovery—When radios detect that a neighbor has failed, they auto-
matically adjust settings so that they can support as many of the stations
associated with the failed radio as possible.
■ Interference avoidance—Radios adjust their channel setting to avoid interfer-
ing with neighboring radios.
