System Maintaining and Debugging

System Maintaining

To do...
Check whether a
specified IP
address can be
reached
View the route from
the source to the
destination
For a low-speed network, you are recommended to set a larger value for the timeout timer
(indicated by the -t parameter in the command) when configuring the ping command.
Only the directly connected segment address can be pinged if the outgoing interface is specified
with the -i argument.

Enable the terminal monitoring
of system information
Enable the terminal display of
debugging information
Enable debugging for a
specified module
Use the command...
ping [ ip ] [ -a source-ip | -c count | -f | -h ttl
| -i interface-type interface-number | -m
interval | -n | -p pad | -q | -r | -s packet-size |
-t timeout | -tos tos | -v | -vpn-instance
vpn-instance-name ] * remote-system
ping ipv6 [ -a source-ipv6 | -c count | -m
interval | -s packet-size | -t timeout ] *
remote-system [ -i interface-type
interface-number ]
tracert [ -a source-ip | -f first-ttl | -m max-ttl |
-p port | -q packet-number | -vpn-instance
vpn-instance-name | -w timeout ] *
remote-system
tracert ipv6 [ -f first-ttl | -m max-ttl | -p port |
-q packet-number | -w timeout ] *
