NOTE
The F2 key functions as a Delete key on VT-100 terminal emulators.
Reboot after making any modifications to the Saved Values or changes will not take
effect. To reboot, type the word reboot at the prompt on the main configuration
screen, or cycle the power.
Never cycle the power with the SNMP Write Lock switch set to ON.
Assigning IP Information
To modify the Saved Parameter Values (i.e., assign IP address and subnet mask), press
I. Enter the IP address and subnet mask for the connected device. Press Enter after
each. A Default Gateway may also be assigned (or press Enter to skip).
When finished, press Enter, then type reboot for changes to take effect. The Saved
Values and Current Values should now both display the changes made (e.g., new IP
address and subnet mask).
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. Delete the
“public” string and add necessary custom community strings such as one with read-
only access (for general use), the other with read/write access (for the administrator).
To create a new community string, go to the main configuration screen and press C.
Enter the name of the new community (up to 16 characters, no spaces) and press
Enter. Assign the community string’s access rights by typing one of the following:
• R = read-only access
• W = read/write access
• Enter = abort
Press Enter to create the Community String. When finished, press Enter, then type
reboot for changes to take effect.
The Saved Values and Current Values should now both display the changes made
(e.g., new IP address and subnet mask).
Deleting Community Strings
To delete all community strings and start over, press U. Press Y to proceed, N to
abort when asked, “Are you sure you want to delete all future strings?” Then, press
Enter.
This function will delete all community strings. Use iConfig to selectively delete
community strings.
