accept) and press Enter. This function enables ALL of the device’s traps. To selectively activate and de-activate traps, use iConfig for configuration. Supported traps are Enterprise specific and include: Link Down, Link Up, Cold Start, Warm Start and Authentication Failure.

Removing Trap Destinations

Creating Community Strings

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. Add the necessary custom community strings such as one with read-only access (for general use), and another with read/write access (for the administrator), then delete the default “public”. 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. Then type one of the following to assign the community string’s access rights:

R = read-only access

W = read/write access

Enter = abort

Press Enter. When finished, press Enter and 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. When asked, “Are you sure you want to delete all future strings?”, press Y to proceed or N to abort. Press Enter.

This function will delete ALL community strings. Use iConfig to selectively delete community strings.

DHCP Enable (Dynamic IP Addressing)
