Testing a Link

The router provides information on network links in the event log, statis- tics, routing tables, and the management information base. The router provides two other specific link tests, Ping and Telnet, described below. Note that you can use HP network management software to test the link. Refer to the help screens for the software.

Tests from Other Devices

This is the procedure to find the station address (also called MAC, physical, or Ethernet address) of a port on this router for use in an IEEE 802.3 test from another network device.

1.From the Main menu, select the Network Control Language Interpreter (NCL). The NCL prompt then appears at the bottom of the screen. For example:
