Figure 4-61 Community and trap host setting.
Parameters description:
SNMP: Used to activate or deactivate SNMP. The 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. In
this case, the requesting network management unit cannot access the device with a 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. No blank spaces are permitted in
the community name string. Any printable character is permitted.
The community name for each function works independently. Each function has its own community name. The community name for
GET only works for the GET function and can’t be applied to other functions such as SET and Trap.
Default SNMP function: Enable
Default community name for GET: public
Default community name for SET: private
Default community name for Trap: public
Default Set function : Enable
Default trap host IP address: 0.0.0.0
Default port number :162
Trap: 6 trap hosts supported in the switch. Each has its own community name and IP address and is user-definable. To set up a trap
host means to create a trap manager by assigning an IP address to host the trap message. The trap host is a network management
unit with SNMP manager receiving the trap message from the managed switch with SNMP agent issuing the trap message. 6 trap
hosts can prevent losing an important trap message.
For each public trap, the switch supports the trap event Cold Start, Warm Start, Link Down, Link Up, and Authentication Failure Trap.
They can be enabled or disabled individually. When enabled, the corresponding trap will actively send a trap message to the trap host
