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.
