4.4.2 Configure SNMP Community
Managed devices are grouped into “communities” wherein every device has the same
“community string” (aka “community name”) to be able to communicate via SNMP. This
string assures authorized access to SNMP. Community strings can provide two types
of access, read-only and read-write. Read-only access allows only get and get-next
commands. Read-write access allows get, get-next and set commands.
The screen shown in Figure 43 allows the definition of up to four SNMP community
names — each specifying either read-only access or read/write access. Before an
access can be used, it must be set to Valid. Each community has three parameters to
be configured :
Content is the string name (up to 10 characters) created by the user. It functions as a
password to be used by any SNMP management software which accesses the switch.
Access is toggled by the user to be either RONLY (read-only) or RWRITE (read-write).
Status is toggled to be either Valid (string enabled) or Invalid (string disabled).
The example of Figure 43 has two community strings defined and valid
: public (set for
read-only access) and private (set for read-write access). (Several commonly-available
SNMP manager applications use the terms public and private as default strings.)
