Configuring the PA-E3 Interfaces

To continue your PA-E3 serial port adapter installation, you must configure the E3 interfaces. The instructions that follow apply to all supported platforms. Minor differences between the platforms are noted. This chapter contains the following sections:

Configuring Cyclic Redundancy Checks, page 8-10

Checking the Configuration, page 8-11

If you installed a new PA-E3 or if you want to change the configuration of an existing interface, you must enter configuration mode using the configure command. If you replaced a PA-E3 that was previously configured, the system recognizes the new PA-E3 interfaces and brings each of them up in their existing configuration.

After you verify that the new PA-E3 is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interfaces. You will need the following information for your configuration:

•

•

•

•

Protocols you plan to route on each new interface

Internet Protocol (IP) addresses if you are configuring the interfaces for IP routing

Plan to use bridging or not on the new interfaces

Timing source for each new interface and clock speeds for external timing

For a summary of the configuration options available and instructions for configuring interfaces on the PA-E3, refer to the appropriate configuration publications listed in the “Related Documentation” section on page vi.

Using the EXEC Command Interpreter

You modify the configuration of your router through the software command interpreter called the EXEC (also called enable mode). You must enter the privileged level of the EXEC command interpreter with the enable command before you can use the configure command to configure a new interface or to change the existing configuration of an interface. The system prompts you for a password if one is set.
