Q: Why is the BSC dropping clients from the connection table? I am using DHCP relay.
A: If you are using DHCP relay the "Time in seconds before idle connections are timed out" under general>misc should be greater than or equal to your dhcp lease time in your external dhcp server. The default value is 600 seconds. If the BSC does not see the dhcp renew at half the lease interval the client will be dropped from the connections table.
