Figure 4-39:  SNMP Management

You can manage this switch using the Simple Network Management Protocol (SNMP) from a 
network management station. To do so, you must configure your switch to participate in the SNMP 
community and you must add the SNMP host agent to the host table.  This prevents unauthorized 
SNMP access to your switch from non-approved SNMP hosts. 

Support for these Standard MIBs is included:

•

MIB II (RFC1213)

•

Ethernet Interface MIB (RFC1643)

•

Bridge MIB (RFC1493)

•

Private Enterprise MIB (see the Resource CD for Managed Switches)

•

4-Group RMON (RFC1757)

Main Menu> Advanced> SNMP> Community Table

You can create up to eight community strings which combine GET, SET, and TRAP privileges.
