map-class frame-relay
To specify a map class to define quality of service (QoS) values for a switched virtual circuit (SVC), use the map-class frame-relay global configuration command.

Usage Guidelines
After you specify the named map class, you can specify the QoS parameters—such as incoming and outgoing committed information rate (CIR), committed burst rate, excess burst rate, and the idle timer—for the map class.
To specify the protocol-and-address combination to which the QoS parameters are to be applied, associate this map class with the static maps under a map list.
Examples
The following example specifies a map class called "hawaii" and defines three QoS parameters for it. The "hawaii" map class is associated with a protocol-and-address static map defined under the map-list command.
map-list bermuda source-addr E164 123456 dest-addr E164 654321
ip 10.108.177.100 class hawaii

Usage Guidelines
A map-group association with an interface is required for switched virtual circuit (SVC) operation. In addition, a map list must be configured.
The map-group command applies to the interface or subinterface on which it is configured. The associated E.164 or X.121 address is defined by the map-list command, and the associated protocol addresses are defined by using the class command under the map-list command.
Examples
The following example configures a physical interface, applies a map group to the physical interface, and then defines the map group:
encapsulation frame-relay
frame-relay lmi-type q933a
map-list bermuda source-addr E164 123456 dest-addr E164 654321
ip 131.108.177.100 class hawaii

Usage Guidelines
Use the map-class command and its subcommands to define quality of service (QoS) parameters—such as incoming and outgoing committed information rate (CIR), committed burst rate, excess burst rate, and the idle timer—for the static maps defined under a map list.
Each SVC needs to use a source and destination number, in much the same way that a public telephone network needs to use source and destination numbers. These numbers allow the network to route calls from a specific source to a specific destination. This specification is done through map lists.
Depending on switch configuration, addressing can take either of two forms: E.164 or X.121.
An X.121 address number is 14 digits long and has the following form:
Table 27 describes the codes in an X.121 address number form.

Can be 1, 2, or 3 digits long. Some current values are the following:
• Code 1—United States of America
• Code 44—United Kingdom
• Code 61—Australia
|
National destination code + subscriber number
|
Referred to as the National ISDN number; the maximum length is 12, 13, or 14 digits, based on the country code.
|
ISDN subaddress
|
Identifies one of many devices at the termination point. An ISDN subaddress is similar to an extension on a PBX.
|
Examples
In the following SVC example, if IP or AppleTalk triggers the call, the SVC is set up with the QoS parameters defined within the class "hawaii". An SVC triggered by either protocol results in two SVC maps, one for IP and one for AppleTalk. Two maps are set up because these protocol-and-address combinations are heading for the same destination, as defined by the dest-addr keyword and the values following it in the map-list command.

Usage Guidelines
Use this command to monitor the PPP link control protocol (LCP) state as being open with an "up" state, or closed with a "down" state.
When "vofr" or "vofr cisco" has been configured on the PVC, and a voice bandwidth has been allocated to the class associated with this PVC, configured voice bandwidth and used voice bandwidth are also displayed.
Statistics Reporting
To obtain statistics about PVCs on all Frame Relay interfaces, use this command with no arguments. When you use the show frame-relay pvc command with no arguments or with the interface argument, a table will display that shows the number of PVCs in the various states.
To obtain statistics about a PVC that include policy-map configuration or the priority configured for that PVC, use this command with the dlci argument.
Per-VC counters are not incremented at all when either autonomous or silicon switching engine (SSE) switching is configured; therefore, PVC values will be inaccurate if either switching method is used.
Traffic Shaping
Congestion control mechanisms are currently not supported on terminated PVCs nor on PVCs over ISDN. Where congestion control mechanisms are supported, the switch passes forward explicit congestion notification (FECN) bits, backward explicit congestion notification (BECN) bits, and discard eligible (DE) bits unchanged from entry to exit points in the network.

The displays in this section show sample output for a variety of PVCs. Some of the PVCs carry data only; some carry a combination of voice and data.

Field

Description
|
DLCI
|
One of the DLCI numbers for the PVC.
|
DLCI USAGE
|
Lists SWITCHED when the router or access server is used as a switch, or LOCAL when the router or access server is used as a DTE device.
|
PVC STATUS
|
Status of the PVC. The DCE device reports the status, and the DTE device receives the status. When you disable the Local Management Interface (LMI) mechanism on the interface (by using the no keepalive command), the PVC status is STATIC. Otherwise, the PVC status is exchanged using the LMI protocol:
• STATIC—LMI is disabled on the interface.
• ACTIVE— The PVC is operational and can transmit packets.
• INACTIVE—The PVC is configured, but down.
• DELETED—The PVC is not present (DTE device only), which means that no status is received from the LMI protocol.
If the frame-relay end-to-end keepalive command is used, the end-to-end keepalive (EEK) status is reported in addition to the LMI status. For example:
• ACTIVE (EEK UP) —The PVC is operational according to LMI and end-to-end keepalives.
• ACTIVE (EEK DOWN)—The PVC is operational according to LMI, but end-to-end keepalive has failed.
