Cisco 2500 Series Access Server

Installing the Cisco 2500 Series Access Server Software

This server requires no software installation. Its operating system is maintained in flash ROM. Configurations are also maintained internally, so there is no need for an external system. These servers boot up automatically and independently when they are powered on.

Configuring a Cisco 2500 Series Access Server Port

You can configure the ports when you first apply power to the system with a console device connected or later by telneting into the server from the LAN. Note that the word console as used in the previous sentence is a Cisco term.

To configure a port, perform the following steps:

  1. You must have a password to access the system and an enable password to enter enable mode.

  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 will now be accessing information for a specific serial line. The serial line must be conditioned to match the communication characteristics of the system that is to be connected.

    This typically means 9600 baud, 8–bit characters, no parity, and 1 stop bit. If the default displayed by the Cisco configuration utility does not match your needs, make appropriate changes.

  4. Specify "modem host" for direct serial connections.

  5. Specify that the port can accept telnet connections from the LAN, using “transport input telnet.”

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

  7. Exit terminal configuration mode.

  8. 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.

Example

Following 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 5                   # configure serial line 5 on the server
>speed 9600                   # indicate line speed is 9600 baud
>databits 8                   # indicate you want 8 bit characters
>parity none                  # indicate you want no parity
>stopbits 1                   # indicate you want 1 stop bit
>modem host                   # directly connected host on the line
>transport input telnet       # accept only telnet connections from the LAN
>exit                         # exit line configuration mode
>exit                         # exit terminal configuration mode
>copy running-config startup-config  # save new cfg to startup cfg

By default, the Cisco server provides a TELNET listener for each serial port.

Add an entry for each port in the file SystemFolder\drivers\etc\services on the Operations Sentinel server, using spo_telnet as the connection type and the port value of 2000 plus the actual port number (1-16).

In addition, you must add the network name of the Cisco server to the file SystemFolder\drivers\etc\hosts on the Operations Sentinel server, to the name server (DNS), or WINS server, so that Operations Sentinel can equate that network name with the Internet address of the server.
