3com 3800 Manual Do Utilizador

In order to have access to the SNMP agent residing in the Switch, at 
least one VLAN on the Switch must have an IP address assigned to it. 
For more information on assigning an IP address, refer to “Manually 
Configuring the IP Settings,” on page 3-6.

If you make configuration changes to the Switch using an SNMP 
manager, you must save the changes so that they are not lost on the 
next Switch reboot. You can save your changes by using the SNMP save 
attribute, or by issuing the 

save

 command from the command line 

interface.

In addition to private MIBs, the Switch 3800 supports the standard 
MIBs listed in Table 3-2.

A trap is a message sent by an SNMP agent to an authorized trap 
receiver (usually a network management station) to indicate the 
occurrence of a significant event, such as an error condition or a 
threshold that has been reached. The Switch 3800 supports the traps 
listed in Table 3-3.
