    NETWORK MANAGEMENT PORT Introduction The Network Management port (NMP) provides access to vital statistics and troubleshooting tools. By connecting a terminal or modem to the NMP a vast array of information is at your finger tips. This information can also be accessed via a terminal device (or PC using terminal emulation software) on port 1 when the port 1 setup switch is depressed.
  • Page 10 Show (WAN/Port) IP Address The Show IP Address (SI) command displays the assigned and actual IP addresses for all ports and the PC port status. It also displays a WAN IP address for the PPP-SR unit. 5.4.4 Frame Relay Status The SS command displays the status of the frame relay connection to the telephone company.
  • Page 11 IDs can be a maximum of 15 characters in length. Pressing <Enter> with no entry will leave the ID unchanged. The ID is used only when accessing the PPP-SR from the NMP. Its use is optional. 5.4.10 Activity Counts / Zero The Activity Counts (AC) command shows transmit and receive data statistics for all ports.
