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-2218 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.
