U10C034 Telephony Version v1.4 June 2008

time_between_pings

Sets or shows the number of milliseconds that the ping helper will wait before sending the next
ping.

verbosity

Sets the level of information that will be displayed while pinging.

verify_enable

Enables/disables verification of ping replies.

wait_enable

Enables/disables waiting for ping replies.

wait_time

Sets or shows the number of milliseconds that the ping helper will wait for a ping response
before continuing.

4.6 SYSTEM

The system commands have two major functions. First one is the log packets function. Packets

are logged when receiving from the specific interfaces sending to the specific interfaces. Another
function is to show all system relative information like flash, memory…, etc.

log_packets

This enables/disables logging for packets received from the specified interfaces and being sent
to the specified interfaces.

show

Show system information including:

flash
memory
fwd_learning_tbl
blocks
