Configuring a Port on a Cisco 2500 Series Access Server

Configuration Procedure

You can configure the ports when you first apply power to the server with a console device connected (“console” here is a Cisco term), or later by accessing the server from the LAN using TELNET.

Follow these steps to configure a port:

  1. Access the server and enter the enable mode with your enable password.

  2. Enter terminal configuration mode to gain access to the specifics for each serial line.

  3. Identify the line you will be configuring, which puts you in line configuration mode. You are now accessing information for a specific serial line.

    The serial line must be conditioned to match the communication characteristics of the connected alert device or the paging service requirements for a modem connection. For a paging service using TAP, this typically means 1200 baud, 7-bit characters, even parity, and 1 stop bit. If the default displayed by the CISCON configuration utility does not match your needs, you should make appropriate changes. In addition, for a modem connection you must tell the server to allow dialing by specifying modem inout.

  4. After your configuration is complete, exit line configuration mode.

  5. Exit terminal configuration mode.

  6. Save your running configuration into your startup configuration, so that when the server is powered up, it will use your new configuration and not the default configuration.

Configuration Example

This is a sample configuration session:

>telnet cisco-as              # Connect to the server
Password:>xxxxxxx           # enter logon telnet password>
enable 								  # enter enable mode
Password:>xxxxxxx           # enter enable mode password>
configure terminal            # enter "terminal configuration" mode
Enter configuration commands, one per line.  
End with Ctrl-Z.>
line tty 4  						  # configure serial line 4 on the server
no exec
flowcontrol hardware>
speed 1200 						  # indicate line speed is 1200 baud>
databits 7       				  # indicate you want 7 bit characters>
parity even      				  # indicate you want even parity>
stopbits 1  						  # indicate you want 1 stop bit>
modem inout						  # the modem can dial or receive calls>
exit    							  # exit line configuration mode>
exit                          # exit terminal configuration mode>
copy running-config startup-config    # save new cfg to startup cfg
