Configuring the PA-T3 Interfaces

To continue your PA-T3 port adapter installation, you must conﬁgure the PA-T3 interfaces. The instructions that follow apply to all supported platforms. Minor differences between the platforms are noted. This chapter contains the following sections:

Using the EXEC Command Interpreter, page 8-2

Identifying Port Adapter Slot and T3 Interface Port Numbers, page 8-2

Shutting Down an Interface, page 8-7

Performing a Basic Conﬁguration, page 8-10

Conﬁguration Example, page 8-11

Customizing the PA-T3 Serial Port Adapter, page 8-12

Conﬁguring Cyclic Redundancy Checks, page 8-13

Checking the Conﬁguration, page 8-14

If you installed a new PA-T3 port adapter 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-T3 port adapter that was previously conﬁgured, the system recognizes the new PA-T3 port adapter interfaces and brings each of them up in their existing conﬁguration.

After you verify that the new PA-T3 port adapter is installed correctly (the enabled LED goes on), use the privileged-level conﬁgure command to conﬁgure the new interfaces. Be prepared with the information you need, such as the following:

•

•

•

•

Protocols you plan to route on each new interface

IP addresses if you will conﬁgure the interfaces for IP routing

Use of bridging 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-T3 port adapter, refer to the appropriate conﬁguration publications listed in the “Related Documentation” section on page vi.

Conﬁguration commands are executed from the privileged level of the EXEC command interpreter, which usually requires password access. Contact your system administrator, if necessary, to obtain access. (See the “Using the EXEC Command Interpreter” section on page 8-2 for an explanation of the privileged level of the EXEC.)
