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-failscommand 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:

set arp-fails fail_count

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:

sms2000% set arp-fails 10

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:

set arp-time seconds

For example, to configure the SMS2000 to wait 10 seconds between intervals when using ARP to test the connection status of subscribers, type:

sms2000% set arp-time 10

Upgrades

The following sections provide detailed steps for installing or upgrading SMS2000 images.

For information on installing and upgrading the OCS software, see the OCS User’s Guide.

You can load new firmware using an http or ftp server. The SMS2000 supports authentication via username and password. You can load the firmware directly from Tut Systems' website. Alternatively, you can locally cache firmware on another ftp or http server, and load the SMS2000 firmware from that server.
