Network Connection Test Commands 353
Use the undo end-station polling ip-address command to delete the IP
address requiring periodic testing.
The switch can ping an IP address every one minute to test if it is reachable. Three
PING packets can be sent at most for every IP address in every testing with a time
interval of five seconds. If the switch cannot ping successfully the IP address after
the three PING packets, it assumes that the IP address is unreachable.
You can configure up to 50 IP addresses by using the command repeatedly.
Related command: ping, tracert.
Example
