D-Link DES-2212 manual Switch Configuration, Snmp Security Community Names

SNMP Security (Community Names)

SNMP (version 1) implements a rudimentary form of security by requiring that each request include a community name. A community name is an arbitrary string of characters used as a “password” to control access to the switch. If the switch receives a request with a community name it doesn’t recognize, it will trigger an authentication trap.

The DES-2212 allows up to four different community names to be defined, and the access rights for each community can be separately set to either read only or read/write. The community names public and private are defined by default; you can change these names in addition to adding others. You will need to coordinate these names with the community name settings you use in your network management system.

Several important switch parameters useful in the day-to-day management of the switch can be viewed and controlled using the Port State menu.
