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 agent that continuously monitors the status of its
hardware, as well as the traffic passing through its ports, based on the Simple
Network Management Protocol (SNMP). A network management station can access
this information using software such as 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 and related trap functions 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
• SNMP Community Capability – Indicates that the switch supports up to five
community strings.
• Community String – A community string that acts like a password and permits
access to the SNMP protocol.
Default strings: “public” (read-only access), “private” (read/write access)
Range: 1-32 characters, case sensitive
• Access Mode
- Read-Only – Specifies read-only access. Authorized management stations are
only able to retrieve MIB objects.
- Read/Write – Specifies read-write access. Authorized management stations are
able to both retrieve and modify MIB objects.
