The server_address argument identifies the IP address of the TFTP server on which your NVG599 operating
software is stored. The filename argument identifies the path and name of the operating software file on the
TFTP server.
If you include the optional keyword confirm , you will not be prompted to confirm whether or not you want to
perform the operation.
log message_string
Adds the message in the message_string argument to the NVG599 diagnostic log.
loglevel [ level ]
Displays or modifies the types of log messages you want the NVG599 to record. If you enter the loglevel
command without the optional level argument, the command line interface displays the current log level
setting.
You can enter the loglevel command with the level argument to specify the types of diagnostic messages you
want to record. All messages with a level number equal to or greater than the level you specify are recorded.
For example, if you specify log level 3, the diagnostic log will retain high-level informational messages (level 3),
warnings (level 4), and failure messages (level 5).
Use the following values for the level argument:
‹
1 or low – Low-level informational messages or greater; includes trivial status messages.
‹
2 or medium – Medium-level informational messages or greater; includes status messages that can help
monitor network traffic.
‹
3 or high – High-level informational messages or greater; includes status messages that may be significant
but do not constitute errors.
‹
4 or warning – Warnings or greater; includes recoverable error conditions and useful operator information.
‹
5 or failure – Failures; includes messages describing error conditions that may not be recoverable.
netstat -i
Displays the IP interfaces for your NVG599.
netstat -r
Displays the IP routes stored in your NVG599.
nslookup [ hostname | ip_address ]
Performs a domain name system lookup for a specified host.
‹
The hostname argument is the name of the host for which you want DNS information; for example,
nslookup klaatu.
‹
The ip_address argument is the IP address, in dotted decimal notation, of the device for which you want
DNS information.
ping [-s size] [-c count ] [ hostname | ip_address ]
Causes the NVG599 to issue a series of ICMP Echo requests for a device with the specified name or IP address.
‹
The
hostname
argument is the name of the device you want to ping; for example,
ping ftp.arris.com.
‹
The ip_address argument is the IP address, in dotted decimal notation, of the device you want to locate. If a
host using the specified name or IP address is active, it returns one or more ICMP echo replies, confirming
that it is accessible from your network.
