Configuring Frame Relay to ATM Interworking Port Adapter Interfaces
Configuring Frame Relay to ATM Virtual Connections
Note
The row index for
rx-cttr
and
tx-cttr
must be configured before using this optional parameter. See
Chapter 9, “Configuring Resource Management.”
Note
When configuring PVC connections, configure the lowest virtual path identifier (VPI) and virtual
channel identifier (VCI) numbers first.
Examples
The following example shows how to configure the internal cross-connect Frame Relay to ATM network
interworking PVC on Switch B between serial interface 0/1/0:5, DLCI = 43 and ATM interface 3/0/2,
VPI = 2, VCI = 100 (see
Figure 20-3
):
Switch-B(config)#
interface serial 0/1/0:5
Switch-B(config-if)#
frame-relay pvc 43 network interface atm 3/0/2 2 100
The following example shows how to configure the internal cross-connect PVC on Switch C between
serial interface 0/0/1:9, DLCI = 255 and ATM interface 4/1/0, VPI = 2, VCI = 100:
Switch-C(config)#
interface serial 0/0/1:9
Switch-C(config-if)#
frame-relay pvc 255 network interface atm 4/1/0 2 100
Note
The Frame Relay to ATM network interworking PVC must be configured from the serial interface and
cross-connected to the ATM interface.
Displaying Frame Relay to ATM Network Interworking PVCs
To display the network interworking configuration, use the following EXEC command:
Example
The following example displays the Switch B PVC configuration for serial interface 0/1/0:5:
Switch-B#
show vc interface serial 0/1/0:5
Interface Conn-Id Type X-Interface X-Conn-Id Encap Status
Serial0/1/0:5 43 PVC ATM3/0/2 2/100 UP
The following example displays the configuration of the Switch B PVC on serial interface 0/1/0:5,
DLCI = 43:
Switch-B#
show vc interface serial 0/1/0:5 43
Interface: Serial0/1/0:5, Type: FRPAM-SERIAL
DLCI = 43 Status : ACTIVE
1.
The serial interface is created with the
channel-group
command and configured using the
encapsulation frame-relay ietf
command.
cgn
is the channel group number of a channel group configured using the
channel-group
command.
2.
The
dlci
value appears in the
Conn-Id
and
X-Conn-Id
columns of the
show vc
command.
3.
The overflow queuing option is described in the section,
Configuring Overflow Queuing, page 20-43
.
