If a WLC has multiple accounting servers defined for a WLAN, will accounting packets be sent to all accounting servers ?
The operation of authentication servers is that the WLC will only send authentication requests to a single RADIUS server. If that RADIUS server becomes unavailable, then the WLC will start to send authentication requests to the next available RADIUS server in the list configured for the WLAN.
Is it the same mode of operation for accounting servers? Or, does the WLC send accounting records to all accounting servers that are defined against a WLAN?
The WLAN will move to next accounting server if the current one is not available. Same with authentication.
