DESCRIPTION

Configuration Backup &

Make a copy of the NXC-8160’s configuration. You can put it back on the

Restoration

NXC-8160 later if you decide to revert back to an earlier configuration.

 

 

IP Multicast

IP multicast is used to send traffic to a specific group of computers. The

 

NXC-8160 supports versions 1 and 2 of IGMP (Internet Group

 

Management Protocol) used to join multicast groups (see RFC 2236).

 

 

Time and Date

Get the current time and date from an external server when you turn on

 

your NXC-8160. You can also set the time manually. These dates and

 

times are then used in logs.

 

 

Logging and Tracing

Use packet tracing and logs for troubleshooting. You can send logs from

 

the NXC-8160 to an external syslog server.

 

 

Cable Pin Assignments

In a serial communications connection, generally a computer is DTE (Data Terminal Equipment) and a modem is DCE (Data Circuit-terminating Equipment). The NXC-8160 is DCE when you connect a computer to the console port.

The pin layout for the DB-9 connector end of the cables is as follows.
