3-6. SNMP Configuration
Any Network Management System (NMS) running the Simple Network Management
Protocol (SNMP) can manage the Managed devices equipped with SNMP agent, provided that
the Management Information Base (MIB) is installed correctly on the managed devices. The
SNMP is a protocol that is used to govern the transfer of information between SNMP manager
and agent and traverses the Object Identity (OID) of the management Information Base (MIB),
described in the form of SMI syntax. SNMP agent is running on the switch to response the
request issued by SNMP manager.
Basically, it is passive except issuing the trap information. The switch supports a switch to
turn on or off the SNMP agent. If you set the field SNMP “Enable”, SNMP agent will be started
up. All supported MIB OIDs, including RMON MIB, can be accessed via SNMP manager. If the
field SNMP is set “Disable”, SNMP agent will be de-activated, the related Community Name,
Trap Host IP Address, Trap and all MIB counters will be ignored.
Function name:
SNMP Configuration
Function description:
This function is used to configure SNMP settings, community name, trap host and public
traps as well as the throttle of SNMP. A SNMP manager must pass the authentication by
identifying both community names, then it can access the MIB information of the target device.
So, both parties must have the same community name. Once completing the setting, click
<Apply> button, the setting takes effect.
Parameters description:
SNMP:
The term SNMP here is used for the activation or de-activation of SNMP. Default is
Enable.
Get/Set/Trap Community:
Community name is used as password for authenticating if the requesting network
management unit belongs to the same community group. If they both don’t have the
same community name, they don’t belong to the same group. Hence, the requesting
network management unit can not access the device with different community name
via SNMP protocol; If they both have the same community name, they can talk each
other.
Community name is user-definable with a maximum length of 15 characters and is
case sensitive. There is not allowed to put any blank in the community name string.
Any printable character is allowable.
The community name for each function works independently. Each function has its
own community name. Say, the community name for GET only works for GET function
and can’t be applied to other function such as SET and Trap.
