3com 9000 SX Manual De Usuario

This chapter describes how to view the current operating status of the 
Switch, how to display information in the Switch log, and how to take 
advantage of the RMON capabilities available in the Switch.

Viewing statistics on a regular basis allows you to:

■

Monitor how well your network is performing

■

Monitor emerging trends and notice problems arising before they 
cause major network faults

The status monitoring facility provides information about the Switch. 
This information may be useful for your technical support 
representative if you have a problem. 

Table 9-1   Switch Monitoring Commands 

show account

Displays the account names, access level, number of successful 
and failed logon attempts, and the number of active sessions 
in the user database. This command is available only to admin 
level users.

show config

Displays the current Switch configuration to the terminal. You 
can then capture the output and store it as a file.

show fdb {all | <macaddress> | vlan 
<name> | <portlist> | permanent}

Displays the forwarding database contents including MAC 
address, associated VLAN, port, age of entry configuration 
method, and status. Providing one of the options acts as a 
filter on the display. Providing a VLAN name displays all entries 
for the VLAN. Use the MAC address to locate a specific entry 
in the FDB.
