Conﬁguring the 4E Interfaces

VIP Port Adapter Functions

Step 2 Attach the ferrite bead to the RJ-45 cable (at either end), as shown in Figure 30.

Caution The ferrite bead prevents electromagnetic interference (EMI) from affecting the 4E-equipped system and is a required component for proper system operation.

Step 3 Attach the network end of your RJ-45 cable to your 10BASE-T hub or repeater, DTE, or other external 10BASE-T equipment.

This completes the 4E installation. Proceed to the section “Checking the VIP Installation” on page 19, then to the section “Conﬁguring the 4E Interfaces,” which follows.

If you installed a new 4E 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 4E port adapter that was previously conﬁgured, the system will recognize the new 4E interfaces and bring them up in their existing conﬁguration.

After you verify that the new 4E 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 will need, such as the following:

•

Protocols you plan to route on each new interface.

Internet protocol (IP) addresses if you plan to conﬁgure the interfaces for IP routing.

Whether the new interfaces will use bridging.

For a summary of the conﬁguration options available and instructions for conﬁguring the 4E interfaces on the VIP, refer to the Router Products Conﬁguration Guide .

The conﬁgure command requires privileged-level access to the EXEC command interpreter, which usually requires a password. Contact your system administrator if necessary to obtain EXEC-level access. The 4E interfaces on a VIP can both be conﬁgured at 10 Mbps, half duplex (HDX) or full duplex (FDX), for a maximum aggregate bandwidth of 40 Mbps.
