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.
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:
In the switch, there are 6 trap hosts supported. Each of them has its own
community name and IP address; 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. In other words, 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 the important trap message from losing.
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 corresponded trap
will actively send a trap message to the trap host when a trap happens. If
all public traps are disabled, no public trap message will be sent. As to
the Enterprise (no. 6) trap is classified as private trap, which are listed in
the Trap Alarm Configuration function folder.
Default for all public traps: Enable.
