Software Configuration for AFR
Note:
AFR is not supported with ATPC. ATPC should be disabled before
configuring AFR. See
Configuring ATPC and ATPC Override Timer
Perform the following steps for each site in the AFR configuration.
•
If you are performing the configuration locally at the Hub site and each Tail
site, the order in which you configure the sites does not matter.
•
If you are performing the configuration for all three sites remotely from the
Hub Site, you must configure the sites in the following order:
◦
Tail Site 1
◦
Tail Site 2
◦
Hub Site
After you configure AFR on the Tails Sites, the link between the Hub Site and the
Tail Sites will be lost. The links will be restored after you configure AFR on the Hub
site and the Hub site comes back up after unit reset.
