The peer router IP address connected to the local interface serial1/0/0 is

202.38.163.252. There is a virtual circuit with DLCI 50 on local Serial1/0/0

connected to this router. Configure the static address mapping as follows:

[3Com-Serial1/0/0] fr map ip 202.38.163.252 50

fr switch name [ interface interface-type interface-number dlci dlci1 interface

interface-type interface-number dlci dlci2 ]

undo fr switch name

name: Name of PVC used for frame relay switching, consisting of 30 characters at

interface interface-type interface-number dlci dlci: DLCI number at both ends of

PVC as well as the type and number of its interface. The peer can be specified as

Tunnel interface.

Using the fr switch command, you can create a PVC used for frame relay switching

and enter frame relay switching view. Using the undo fr switch command, you can

delete a specified PVC.

By default, there is no PVC used for frame relay switching.

The interface for forwarding packets can be either a frame relay interface or an

MFR interface. If Tunnel interface is specified as the forwarding interface, frame

relay packets over IP can thus be realized.

In frame relay switching view, the shutdown/undo shutdown operation can be

executed on a PVC.

If a PVC used for switching has been configured, its interface and DLCI cannot be

changed any longer. To change them, you must delete the defined PVC used for

switching first.

For the related commands, see display fr pvc-info, fr dlci-switch, fr switching, and

Create a PVC named pvc1 on the DCE serving as the switch, which is from the

DCLI 100 of serial interface 0/0/0 to the DLCI 200 of serial interface 1/0/0.
