Tahoe 4681 (4-port G.shdsl.bis/FastEthernet modem card)
watchdog
The watchdog command gives additional control over the modem’s unpredicted behavior (i.e. a
misconfiguration disabling further communication with the modem). The modem sends ICMP
ping packetd to check the availability of certain IP addresses and reboots, if it doesn’t receive
ping reply from one of them.
The command has following syntax:
watchdog on
– enables the watchdog
watchdog off
– disables the watchdog
watchdog
<
interval
> <
amount
> <
wait
> <
IP address
>
[
<
additional IP address
>
]
– configures the watchdog. After < interval > seconds the modem sends < amount > of pings
to the < IP address > (and the < additional IP address > if set) waiting < wait > seconds after
each of them. If there is no answer for any of the pings sent to the first address or for any of
the pings sent to the second address, then the modem is rebooted.
write
Saves the current configuration to the EEPROM (non-volatile memory) so the modem keeps it
after reboot or power off. The command also displays an information about the EEPROM us-
age. If the configuration is too large to be stored some settings should be deleted, like static ARP
entries, DHCP options, etc.
