ADD OR CHANGE AN SNMP TRAP HOST ON THE NMIC
Summary: The following procedure describes the steps required to add or change SNMP trap hosts on the Cellworx STN NMICs. A trap host is the system or network IP configured to receive traps that are initiated by the Cellworx STN system. The trap messages may be used to track problems with the system or stored for statistical data. The file to be changed is is config.snmp.active and is located in the /cellworx/config directory. To help in the navigation of the unix shell, here are some general commands that the user may need. The user should have some UNIX experience before accessing or modifying these files.
Some vi commands:
•:help – use arrows to navigate
•:q – quit
•:sh – Opens shell in vi 9
•Up arrow – scrolls through recalled commands
•Delete key – exits without saving to start over, NEVER use backspace!!!
1.Telnet to the NMIC and at the NMIC command line, type in the following command:
•# export TERM=vt100
•# vi /cellworx/config/config.snmp.active
2.Figure 775-1 shows an example of an unedited NMIC file that should be displayed. Notice the last MANAGER line shows only a localhost as the recipient of the traps.
3.There are two lines that need to be added to the file. In the example shown in Figure 775-2, we have added an SNMP Trap host of 192.168.10.90. To do this, use the Down Arrow keys to move the cursur to the last line starting with “MANAGER”.
4.With the cursor at the beginning of the line enter “y3y”. This will “yank” three lines to the clip board.
5.Use the Down Arrow keys to step down one line and enter a “p” to paste the two lines into the file.
6.An exact duplicate of the MANAGER localhost lines are now displayed. Use the Arrow keys to move the cursor to the second MANAGER localhost line and position the cursor just before localhost.
7.Enter a Shift+C and begin typing the new SNMP Trap host IP address. Typing will overwrite the localhost if the Shift+C keys were entered correctly.
8.After correctly entering the IP address, hit Esc to leave the insert mode.
