Creating Community Strings for SNMP
The purpose of community strings is to add a level of security to a network. The
default community string is named “public” and has read/write access. We
recommend deleting Public, then adding necessary custom communities strings such
as one with read-only access (for general use), the other with read/write access (for
the administrator).
Follow these steps to create a new community string.
1.
From the Main Configuration screen, press
C
.
2.
Enter the name of the new community (up to 16 characters, no spaces) and
press
Enter
.
3.
Type one of the following to assign the community string’s access rights
R
– read-only access
W
– read/write access
Enter
– abort
4. Press
Enter
.
5. Type
reboot
for changes to take effect.
Result:
The Saved Values and Current Values should now both display the
changes made (e.g., new IP address and subnet mask).
Deleting Community Strings
Follow these steps to delete all community strings and start over.
1.
From the Main Configuration screen, press
U
.
Result:
You will be asked,
Are you sure you want to delete all future
strings?
2.
Press
Y
to proceed
OR
press
N
to abort.
3. Press
Enter
.
Result:
This function will delete ALL community strings. If you want to be
able to selectively delete community strings, use iConfig to configure your
device.
