Simple Network Management Protocol
Simple Network Management Protocol (SNMP) is a communication
protocol designed specifically for managing devices on a network.
Equipment commonly managed with SNMP includes switches, routers
and host computers. SNMP is typically used to configure these devices for
proper operation in a network environment, as well as to monitor them to
evaluate performance or detect potential problems.
The switch includes an onboard SNMP agent that continuously monitors
the status of its hardware, as well as the traffic passing through its ports. A
network management station can access this information using software
such as SMC EliteView or HP OpenView. Access rights to the onboard
agent are controlled by community strings. To communicate with the
switch, the management station must first submit a valid community string
for authentication. The options for configuring community strings, trap
functions, and restricting access to clients with specified IP addresses are
described in the following sections.
Setting Community Access Strings
You may configure up to five community strings authorized for
management access. All community strings used for IP Trap Managers
should be listed in this table. For security reasons, you should consider
removing the default strings.
Command Attributes

up to five community strings.
Community String – A community string that acts like a password
and permits access to the SNMP protocol.
