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

(Optional) Number of seconds that must elapse after the last voice packet is transmitted before the sending rate is increased to the committed information rate (CIR). The range is from 1 to 10000.

Command Default

Frame Relay voice-adaptive traffic shaping is not enabled. 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-adaptcommand can be configured only in the class-default class. If you configure the shape fr-voice-adaptcommand 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.

Table 3 show ccm sessions Field Descriptions

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.

Current

Timeout

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.

The table below describes the fields shown in the display.

Table 12 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.

Usage Guidelines

When no parameters are specified with this command, the output displays a summary of each DLCI configured for fragmentation. The information displayed includes the fragmentation type, the configured fragment size, and the number of fragments transmitted, received, and dropped.

When a specific interface and DLCI are specified, additional details are displayed.

Examples

The following is sample output for the show frame-relay fragment command without any parameters specified:

Router# show frame-relay fragment
interface         dlci  frag-type    frag-size  in-frag    out-frag   dropped-frag
Serial0           108   VoFR-cisco   100        1261       1298       0

Serial0           110   end-to-end   100        0          0          0

The show frame-relay fragment command does not display any data in the in-frag and out-frag columns (displays 0) when high-priority data is flowing. The in-frag and out-frag columns are updated when low-priority data (only when packet size is greater than or equal to fragment size) is sent across the link.

The following is sample output for the show frame-relay fragment command when an interface and DLCI are specified:

Router# show frame-relay fragment interface Serial1/0 16

The following sample output from the show frame-relay map command shows that the link-local and global IPv6 addresses (FE80::E0:F727:E400:A and 2001:0DB8:2222:1044::32; FE80::60:3E47:AC8:8 and 2001:0DB8:2222:1044::32) of two remote nodes are explicitly mapped to DLCI 17 and DLCI 19, respectively. Both DLCI 17 and DLCI 19 are terminated on interface serial 3 of this node; therefore, interface serial 3 of this node is a point-to-multipoint interface.

The table below describes significant fields shown in the displays.

Table 19 show frame-relay multilink Field Descriptions

Field

Description

Bundle

Bundle interface.

State

Operational state of the bundle interface.

class

The bandwidth class criterion used to activate or deactivate a Frame Relay bundle.

  • Class A (single link)--The bundle activates when any bundle link is up and deactivates when all bundle links are down (default).
  • Class B (all links)--The bundle activates when all bundle links are up and deactivates when any bundle link is down.
  • Class C (threshold)--The bundle activates when the minimum configured number of bundle links (the threshold) is up and deactivates when the minimum number of configured bundle links fails to meet the threshold.

BID

Bundle identification.

Bundle links

Bundle links for which information is displayed.

HW state

Operational state of the physical link.

Protocol state

Operational state of the bundle link line protocol.

link state

Operational state of the bundle link.

LID

Bundle link identification.

Bundle interface

Bundle interface with which the bundle link is associated.

Cause code

Can be one of the following values:

  • ack timer expiry--Add link synchronization process is exhausted.
  • bundle link idle--Peer’s bundle link is idle. This usually occurs when the peer’s bundle interface is shut down.
  • inconsistent bundle--Peer already has this bundle associated with another bundle.
  • loopback detected--Local bundle link’s physical line is looped back.
  • none--ADD_LINK and ADD_LINK_ACK messages were properly exchanged, and no cause code was recorded.
  • other--Indicates one of the following: a link identifier (LID) mismatch, an ID from the peer that is too long, or a failure to allocate ID memory.
  • unexpected Add_link--ADD_LINK message is received when the bundle link is already in the “up” state. This code might appear when the line protocol is being set up, but will disappear once the connection is stabilized.

Ack timer

Number of seconds for which the bundle link waits for a hello acknowledgment before resending a hello message or resending an ADD_LINK message used for initial synchronization.

Hello timer

Interval at which a bundle link sends out hello messages.

Max retry count

Maximum number of times that a bundle link will resend a hello message before receiving an acknowledgment or resending an ADD_LINK message.

Current count

Number of retries that have been attempted.

Peer LID

Bundle link identification name of the peer end of the link.

RTT

Round-trip time (in milliseconds) as measured by using the Timestamp Information Element in the HELLO and HELLO_ACK messages.

Statistics

Displays statistics for each bundle link.

Add_link sent

Number of Add_link messages sent. Add_link messages notify the peer endpoint that the local endpoint is ready to process frames.

Add_link rcv’d

Number of Add_link messages received.

Add_link ack sent

Number of Add_link acknowledgments sent. Add_link acknowledgments notify the peer endpoint that an Add_link message was received.

Add_link ack rcv’d

Number of Add_link acknowledgments received.

Add_link rej sent

Number of Add_link_reject messages sent.

Add_link rej rcv’d

Number of Add_link_reject messages received.

Remove_link sent

Number of Remove_link messages sent. Remove_link messages notify the peer that on the local end a bundle link is being removed from the bundle.

Remove_link rcv’d

Number of Remove_link messages received.

Remove_link_ack sent

Number of Remove_link acknowledgments sent. Remove_link acknowledgments notify the peer that a Remove_link message has been received.

Remove_link_ack rcv’d

Number of Remove_link acknowledgments received.

Hello sent

Number of hello messages sent. Hello messages notify the peer endpoint that the local endpoint remains in the “up” state.

Hello rcv’d

Number of hello messages received.

Hello_ack sent

Number of hello acknowledgments sent. Hello acknowledgments notify the peer that hello messages have been received.

Hello_ack rcv’d

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.

12.0(33)S

Support for IPv6 was added. This command was implemented on the Cisco 12000 series routers.

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 allkeywords.

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.

Examples

The various 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. This section contains the following examples:

The following example shows sample output of the show frame-relay pvc command with the summary keyword. The summary keyword displays all PVCs on the system.

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

Examples

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.

Router# show frame-relay vc-bundle MP-4-dynamic

Examples

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.

Usage Guidelines

Use the show mdns cache command to display resource record data for all mDNS service discovery devices. This command lets you retrieve and resolve mDNS service discovery resource record information that is cached. The resource records belong to the Internet class are denoted by IN.

This command displays information about the following types of resource records:

  • Services Resolved (SRV) Records: Records where the instance name to hostname resolution is complete.
  • Point to Record (PTR) Records: Records listing all instances of the resource.
  • A Records: Records where the IPv4 address resolution is complete.
  • AAAA Records: Records where the IPv6 address resolution is complete.

This command also provides information about the Time to Live (TTL) value for each resource record. The TTL value denotes the time line for which the resource record can remain active in the cache.

The RR Record Data column displays miscellaneous information and notes about the resource records.

The table below describes the significant fields shown in the display.

Table 52 show otv isis database detail Field Descriptions

Field

Description

LSPID

LSP identifier. The first six octets form the system ID of the router that originated the LSP. The next octet is the pseudonode ID. When this byte is zero, the LSP describes links from the system. When it is nonzero, the LSP is a pseudonode LSP.

The last octet is the LSP number. If all data cannot fit into a single LSP, the LSP is divided into multiple LSP fragments. Each fragment has a different LSP number.

LSP Seq Num

LSP sequence number that allows other systems to determine if they received the latest information from the source.

LSP Checksum

Checksum of the entire LSP packet.

LSP Holdtime

Amount of time (in seconds) for which the LSP remains valid. An LSP hold time of zero indicates that this LSP was purged and is being removed from all routers’ link state databases (LSDBs). The value indicates how long the purged LSP will stay in the LSDB before it is completely removed.

ATT

Attach bit. This bit indicates that the router is also a Level 2 router and that it can reach other areas. Level 1 routers use the Attach bit to find the closest Level 2 router. They install a default route to the closest Level 2 router.

P

P bit. This bit detects if the IS can repair area partitions. Cisco and other vendors do not support area partition repair.

OL

Overload bit. This bit determines if the IS is congested. If the overload bit is set, other routers do not use this system as a transit router when they calculate routes. Only packets for destinations directly connected to the overloaded router are sent to this router.

Area Address

Reachable area addresses from the router. For Level-1 LSPs, these are the area addresses configured manually on the originating router. For Level-2 LSPs, these are all the area addresses for the area to which this router belongs.

NLPID

Network Layer Protocol (NLP) identifier.

Hostname

Hostname of the node.

Layer 2 MAC Reachability

Layer 2 MAC Reachability type, length, values (TLVs) and displays the MAC address that the IS is advertising, and the MAC address that can be reached from this IS.

*     AABB.CC00.0300   u3
1     AABB.CC00.0200   u2

The dynamic hostname table in the example displays the router name-to-system ID mapping table entries for router u1, router u2, and the local router u3. The command output shows that the local router is running the IS-IS process named Overlay1. The table also shows that the neighbor routers u1 and u2 are Level-1 routers, and their hostnames are advertised by the Level-1 (L1) link-state packet (LSP). The * symbol that appears for the router u3 signifies that this is the router name-to-system ID mapping information for the local router.

Table 58 show otv isis spf-log Field Descriptions

Field

Description

When

The time elapsed (in hours: minutes: seconds) since the last full SPF calculation occurred. The last 20 occurrences are logged.

Duration

Time (in milliseconds) required to complete this SPF run. Elapsed time is clock time, not CPU time.

Nodes

Number of routers and pseudonodes (LANs) that comprise the topology calculated in this SPF run.

Count

Number of events that triggered this SPF run. When there is a topology change, often multiple link-state packets (LSPs) are received in a short time. A router waits for 5 seconds before running a full SPF run, so it can include all new information. This count denotes the number of events (such as receiving new LSPs) that occurred while the router was waiting for 5 seconds before running full SPF.

First trigger LSP

Whenever a full SPF calculation is triggered by the arrival of a new LSP, the router stores the LSP ID. The LSP ID can provide a clue as to the source of routing instability in an area. If multiple LSPs are causing an SPF run, only the LSP ID of the first received LSP is remembered.

Triggers

A possible reason that triggered a full SPF calculation.
