Subscriber Connectivity Commands

Setting the ARP Failure Limit

The SMS2000 periodically sends an unsolicited ARP request to clients from whom it has
not received network traffic for a certain period of time. If a device does not respond to
the specified number of requests, the SMS2000 assumes that it has been disconnected and
closes the session with the device. The set arp-fails command allows you to set the
number of allowed failures.
To set the maximum number of ARP failures allowed before a device is assumed to be
down or disconnected, use this command:
For example, to configure the SMS2000 to end subscriber sessions, if no response is
received from a subscriber after 10 ARP requests are sent, type:

Setting the ARP Polling Period

The SMS2000 uses unsolicited ARP requests to verify client connectivity. This allows
you to select theminimum polling period and response time in seconds for client ARP
requests.
To set the ARP polling period, in seconds, type:
For example, to configure the SMS2000 to wait 10 seconds between intervals when using
ARP to test the connection status of subscribers, type:
