The Diagnostics Menu

The GUI’s diagnostics pages enable you to troubleshoot network problems and observe traffic flow, including:

• displaying the number of good and bad packets received and transmitted over each switch port

• displaying the number and type of PPP packets received and transmitted

• displaying the number and type of packets received and transmitted by IP, and discarded by the IP gateway

• displaying the number and type of ICMP and UDP packets received and transmitted

• displaying the number and type of RIP packets received and transmitted; and the octets received and transmitted over each IP route

• displaying the contents of the switch’s file system and how much memory is used and available. You can also delete files

• an interface to the switch’s command line interface, allowing you to enter CLI commands.
