if we use the single-connection feature at the router configuration do we need to select the single connect option at the AAA Client setup:
Single Connect TACACS+ AAA Client (Record stop in accounting on failure)
Select this option to enable a single-connect TACACS+ AAA client. This allows all TACACS+ sessions between the AAA client and ACS to occur over a single TCP session rather than separate sessions for each request. If this feature is selected and the connection fails, a stop record is sent to the TACACS+ accounting log for each user connected through the AAA client.
or is this just only for sending the stop record?
