Greetings, I'm looking to roll out a GPON deployment using the ISG as our BRAS with DHCP-based sessions but we are experience some problems with session restart. We're using an external DHCP server and RADIUS. Sessions come up fine the first time, but if there is an existing session and the CPE node is rebooted the session gets "stuck". To clear the session we turn off the CPE device, clear the state in the GPON shelf and wait for more than 5 minutes. Doing some debug shows the SG-DPM process thinking there is an existing DHCP lease that seems to clear out after five minutes of "silence". I'd like to get this five minutes down to something in the less than 60 seconds range. Anybody know of any knobs to tweak this? Or is this "normal" behavior?
