12.2(28)SB

AToM support for this command was integrated into Cisco IOS Release 12.2(28)SB.


Usage Guidelines

When you enable sequencing using any of the available options, the sending of sequence numbers is automatically enabled and the remote provider edge (PE) peer is requested to send sequence numbers. Out-of-order packets received on the pseudowire are dropped only if you use the sequencing receive or sequencing both command.

If you enable sequencing for Layer 2 pseudowires on the Cisco 7500 series routers and you issue the ip cef distributed command, all traffic on the pseudowires is switched through the line cards.

It is useful to specify the resync keyword for situations when the disposition router receives many out-of-order packets. It allows the router to recover from situations where too many out-of-order packets are dropped.

Examples

The following example shows how to enable sequencing in data packets in Layer 2 pseudowires that were created from the pseudowire class named "ether-pw" so that the Sequence Number field is updated in tunneled packet headers for data packets that are both sent and received over the pseudowire: 

Router(config)# pseudowire-class ether-pw

Router(config-pw)# encapsulation mpls

Router(config-pw)# sequencing both

The following example shows how to enable the disposition router to reset packet sequencing after it receives 1000 out-of-order packets: 

Router(config)# pseudowire-class ether-pw 

Router(config-pw)# encapsulation mpls 

Router(config-pw)# sequencing both 

Router(config-pw)# sequencing resync 1000

Seconds: 30

Command Modes

Policy-map class configuration

Command History

Release
Modification

12.2(15)T

This command was introduced.


Usage Guidelines

Frame Relay voice-adaptive traffic shaping enables a router to reduce the permanent virtual circuit (PVC) sending rate to the minimum CIR (minCIR) whenever packets (usually voice) are detected in the low latency queueing priority queue or H.323 call setup signaling packets are present. When there are no packets in priority queue and signaling packets are not present for a configured period of time, the router increases the PVC sending rate from minCIR to CIR to maximize throughput.

The shape fr-voice-adapt command can be configured only in the class-default class. If you configure the shape fr-voice-adapt command in another class, the associated Frame Relay map class will be rejected when you attach it to the interface.

Frame Relay voice-adaptive traffic shaping can be used with other types of adaptive traffic shaping. For example, when both voice-adaptive traffic shaping and adaptive shaping based on interface congestion are configured, the sending rate will change to minCIR if there are packets in the priority queue or the interface queue size exceeds the configured threshold.

Note Although the priority queue is generally used for voice traffic, Frame Relay voice-adaptive traffic shaping will respond to any packets (voice or data) in the priority queue.

In order to use Frame Relay voice-adaptive traffic shaping, you must have low latency queueing and traffic shaping configured using the Modular QoS CLI.

Examples

The following example shows the configuration of Frame Relay voice-adaptive traffic shaping and fragmentation. With this configuration, priority-queue packets or H.323 call setup signaling packets destined for PVC 100 will result in the reduction of the sending rate from CIR to minCIR and the activation of FRF.12 end-to-end fragmentation. If signaling packets and priority-queue packets are not detected for 50 seconds, the sending rate will increase to CIR and fragmentation will be turned off.

Field
Description

Global CCM state

Displays the processor's active or standby status and its CCM state. For example:

CCM HA Active - Dynamic Sync means that this is the active processor, standby is in STANDBY_HOT state, and CCM is ready to synchronize sessions.

CCM HA Active - Collecting means that this is the active processor and there is no standby processor. CCM can collect sessions but cannot synchronize them to a standby processor.

CCM HA Active - Bulk Sync means that this is the active processor and a standby processor is booting up. CCM is doing a bulk synchronization of sessions.

CCM HA Standby- Collecting means that this is the standby processor and is in STANDBY_HOT state. CCM is collecting sessions for synchronizing if a switchover happens.

Global ISSU state

Compatible, Clients Cap 0xFFFE0 indicates that CCM is compatible for in-service software upgrade (ISSU) clients, that is, ISSU-compatible Cisco IOS versions are running on both processors. It also means that CCM has the client capability for clients in the bitmask 0xFFFE.

Displays statistics for the following timers:

Rate—Monitors the number of sessions to be synchronized per configured time period.

Dynamic CPU—Monitors the CPU limit, number of sessions, delay, and allowed calls configured for dynamic synchronization parameters.

Bulk Time Li—Monitors the time limit configured for bulk synchronization.

RF Notif Ext—Monitors redundancy facility (RF) active and standby state progressions and events.

Use the subscriber redundancy command to modify parameters that these timers monitor.

Delay

Timer delay (in hh:mm:ss) for bulk and dynamic synchronization of subscriber sessions.

Remaining

Indicates the remaining time in seconds before the timer expires.

Starts

Indicates the number of times the timer started.

Table 31 describes the fields shown in the display.

Table 31 show frame-relay end-to-end keepalive Field Descriptions 

Field
Description

DLCI

The DLCI number that identifies 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.

VC 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.

Send Sequence Number

The current sequence number being sent in the keepalive packets.

Receive Sequence Number

The last sequence number received in the incoming keepalive packets.

Configured Event Window

The value configured by frame-relay end-to-end keepalive event-window command.

Configured Error Threshold

The value configured by frame-relay end-to-end keepalive error-threshold command.

Total Observed Events

The total number of successful events counted.

Total Observed Errors

The total number of error events counted.

Monitored Events

The number of events in current event window.

Monitored Errors

The number of errors in current event window.

Successive Successes

The number of successive success events in the current event window.

End-to-end VC Status

The status of the end-to-end keepalive protocol. The status is either UP or DOWN.

Failures Since Started

The number of times the end-to-end keepalive protocol has failed, causing the DLCI to go into the EEK DOWN state, since the protocol started.

Last Failure

The elapsed time since the last failure.

Modification

10.0

This command was introduced.

12.0(1)T

This command was modified to display statistics about virtual access interfaces used for PPP connections over Frame Relay.

12.0(3)XG

This command was modified to include the fragmentation type and size associated with a particular PVC when fragmentation is enabled on the PVC.

12.0(4)T

This command was modified to include the fragmentation type and size associated with a particular PVC when fragmentation is enabled on the PVC.

12.0(5)T

This command was modified to include information on the special voice queue that is created using the queue keyword of the frame-relay voice bandwidth command.

12.1(2)T

This command was modified to display the following information:

•Details about the policy map attached to a specific PVC.

•The priority configured for PVCs within Frame Relay PVC interface priority queueing.

•Details about Frame Relay traffic shaping and policing on switched PVCs.

12.0(12)S

This command was modified to display reasons for packet drops and complete status information for switched NNI PVCs.

12.1(5)T

This command was modified to display the following information:

•The number of packets in the post-hardware-compression queue.

•The reasons for packet drops and complete status information for switched network-to-network PVCs.

12.0(17)S

This command was modified to display the number of outgoing packets dropped and the number of outgoing bytes dropped because of QoS policy.

12.2 T

This command was modified to show that when payload compression is configured for a PVC, the throughput rate reported by the PVC is equal to the rate reported by the interface.

12.2(4)T

The 64-bit keyword was added.

12.2(11)T

This command was modified to display the number of outgoing packets dropped and the number of outgoing bytes dropped because of QoS policy.

12.2(13)T

12.2(28)SB

This command was integrated into Cisco IOS Release 12.2(28)SB, and support was added for hierarchical queueing framework (HQF).

12.4(9)T

The summary and all keywords were added, and support was added for hierarchical queueing framework (HQF).

12.2(33)SRA

This command was integrated into Cisco IOS Release 12.2(33)SRA.

12.2SX

This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.


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.

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.

To display a summary of all PVCs on the system, use the show frame-relay pvc command with the summary keyword. To display a summary of all PVCs per interface, use the summary all keywords.

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.

You can change the period of time over which a set of data is used for computing load statistics. If you decrease the load interval, the average statistics are computed over a shorter period of time and are more responsive to bursts of traffic. To change the length of time for which a set of data is used to compute load statistics for a PVC, use the load-interval command in Frame-Relay DLCI configuration mode.

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 points to exit points in the network.

Usage Guidelines

Use this command to display packet service levels, bumping attributes, and other information about a specific Frame Relay PVC bundle. To view packet counts for each PVC in the bundle in addition to the other attributes, use the detail keyword.

Examples

Displaying General Information: Example

The following example shows the Frame Relay PVC bundle named "MP-4-dynamic" with PVC protection applied. Note that in this PVC bundle, data-link connection identifier (DLCI) 400 is configured to explicitly bump traffic to the PVC that handles DSCP level 40, which is DLCI 404. All the other DLCIs are configured for implicit bumping. In addition, all the DLCIs are configured to accept bumped traffic.

The asterisk (*) before PVC 4a indicates that this PVC was configured with the precedence other command, which means the PVC will handle all levels that are not explicitly configured on other PVCs.

In this example all PVCs are up so, the values in the "Active level" fields match the values in the "Config level" fields. If a PVC goes down and its traffic is bumped, the "Active level" field value for the PVC that went down is cleared. The "Active level" field values for the PVC that the traffic bumped to will be updated to include the levels of the PVC that went down.

The first three PVCs in the following example make up a protected group. All three of these PVCs must go down before the bundle will go down. The last two PVCs are protected PVCs: if either of these PVCs goes down, the bundle will go down.

Bumping: Example

The following example shows that although some DLCIs are down, the bumping rules and the remaining DLCIs keep the bundle up and running for all traffic types.

Note that DLCI 304 is handling the traffic being bumped from the three DLCIs that are down. The "Active level" field indicates the levels that the PVC is actually handling, not just which levels are configured.
