debug dlsw

Use the debug dlsw privileged EXEC command to enable debugging of DLSw+. The no form of this command disables debugging output.

debug dlsw [border-peers [interface interface | ip address ip-address] | core [flow-control messages | state | xid] [circuit-number] | local-circuit circuit-number | peers [interface interface [fast-errors | fast-paks] | ip address ip-address [fast-errors | fast-paks | fst-seq | udp]] | reachability [error | verbose] [sna | netbios]
no debug dlsw [border-peers [interface interface | ip address ip-address] | core [flow-control messages | state | xid] [circuit-number] | local-circuit circuit-number | peers [interface interface [fast-errors | fast-paks] | ip address ip-address [fast-errors | fast-paks | fst-seq | udp]] | reachability [error | verbose] [sna | netbios]
Syntax Description

border-peers

(Optional) Enables debugging output for border peer events.

interface interface

(Optional) Specifies a remote peer to debug by a direct interface.

ip address ip-address

(Optional) Specifies a remote peer to debug by its IP address.

core

(Optional) Enables debugging output for DLSw core events.

flow-control

(Optional) Enables debugging output for congestion in the WAN or at the remote end station.

messages

(Optional) Enables debugging output of core messages—specific packets received by DLSw either from one of its peers or from a local medium via the Cisco link services interface.

state

(Optional) Enables debugging output for state changes on the circuit.

xid

(Optional) Enables debugging output for the exchange identification-state machine.

circuit-number

(Optional) Specifies the circuit for which you want core debugging output to reduce the of output.

local-circuit circuit-number

(Optional) Enables debugging output for circuits performing local conversion. Local conversion occurs when both the input and output data-link connections are on the same local peer and no remote peer exists.

peers

(Optional) Enables debugging output for peer events.

fast-errors

(Optional) Debugs errors for fast-switched packets.

fast-paks

(Optional) Debugs fast-switched packets.

fst-seq

(Optional) Debugs FST sequence numbers on fast switched packets.

udp

(Optional) Debugs UDP packets.

reachability

(Optional) Enables debugging output for reachability events (explorer traffic). If no options are specified, event-level information is displayed for all protocols.

error | verbose

(Optional) Specifies how much reachability information you want displayed. The verbose keyword displays everything, including errors and events. The error keyword displays error information only. If no option is specified, event-level information is displayed.

sna | netbios

(Optional) Specifies that reachability information be displayed for only SNA or NetBIOS protocols. If no option is specified, information for all protocols is displayed.

Usage Guidelines

When you specify no optional keywords, the debug dlsw command enables all available DLSw debugging output.

Normally you need to use only the error or verbose option of the debug dlsw reachability command to help identify problems. The error option is recommended for use by customers and provides a subset of the messages from the normal event-level debugging. The verbose option provides a very detailed view of what is going on and is typically used only by service personnel.

To reduce the amount of debug information displayed, use the sna or netbios options with the debug dlsw reachability command if you know that you have an SNA or NetBIOS problem.

The DLSw core is the engine that is responsible for the establishment and maintenance of remote circuits. If possible, specifying the index of the specific circuit you want to debug reduces the amount of output displayed. However, if you want to watch a circuit initially come up, do not use the circuit-number option with the core keyword.

The core flow-control option provides information about congestion in the WAN or at the remote end station. In these cases, DLSw sends Receiver Not Ready (RNR) frames on its local circuits, slowing data traffic on established sessions and giving the congestion an opportunity to clear.

The core state option allows you to see when the circuit changes state. This capability is especially useful for determining why a session cannot be established or why a session is being disconnected.

The core XID option allows you to track the XID-state machine. The router tracks XID commands and responses used in negotiations between end stations before establishing a session.

Examples

The following sections show and explain some of the typical DLSw debug messages you might see when using the debug dlsw command.

The following example enables UDP packet debugging for a specific remote peer:
Router# debug dlsw peer ip-address 1.1.1.6 udp
The following message is sample output from the debug dlsw border-peers command:
*Mar 10 17:39:56: CSM: delete group mac cache for group 0
*Mar 10 17:39:56: CSM: delete group name cache for group 0
*Mar 10 17:40:19: CSM: update group cache for mac 0000.3072.1070, group 10
*Mar 10 17:40:22: DLSw: send_to_group_members(): copy to peer 10.19.32.5

Sample Debug DLSw Reachability Messages

The messages in this section are based on the following items:

•Reachability is stored in cache. DLSw+ maintains two reachability caches: one for MAC addresses and one for NetBIOS names. Depending on how long entries have been in the cache, they are either fresh or stale.

•If a router has a fresh entry in the cache for a certain resource, it answers a locate request for that resource without verifying that it is still available. A locate request is typically a TEST frame for MAC addresses or a FIND_NAME_QUERY for NetBIOS.

•If a router has a stale entry in the cache for a certain resource, it verifies that the entry is still valid before answering a locate request for the resource by sending a frame to the resource's last known location and waits for a resource. If the entry is a REMOTE entry, the router sends a CUR_ex frame to the remote peer to verify. If the entry is a LOCAL entry, it sends either a TEST frame or a NetBIOS FIND_NAME_QUERY on the appropriate local port.

•By default, all reachability cache entries remain fresh for 4 minutes after they are learned. For MAC addresses, you can change this time with the dlsw timer sna-verify-interval command. For NetBIOS names, you can change this with the dlsw timer netbios-verify-interval command.

•By default, all reachability cache entries age out of the cache 16 minutes after they are learned. For MAC addresses, you can change this time with the dlsw timer sna-cache-timeout command. For NetBIOS names, you can change the time with the dlsw timer netbios-cache-timeout command.

Table 40 describes the debug output indicating that the DLSW router received an SSP message that is flow controlled and should be counted against the sender's window.
Dec  6 11:26:49: CSM: Received SSP  CUR   csex flags = 80, mac 4000.90b1.26cf,

debug drip event

Use the debug drip event privileged EXEC command to display debug messages for Duplicate Ring Protocol (DRiP) events. Use the no form of this command to disable debugging output.

debug drip event
no debug drip event
Syntax Description

This command has no arguments or keywords.

Defaults

Debugging is disabled for DRiP events.

Command History

Release

Modification

11.3(4)T

This command was introduced.

Usage Guidelines

When a TrBRF interface is configured on the RSM, the DRiP protocol is activated. The DRiP protocol adds the VLAN ID specified in the router command to its database and recognizes the VLAN as a locally configured, active VLAN.

Examples

Following examples show output for the debug drip event command.

DRiP gets a packet from the network:
612B92C0: 01000C00 00000000 0C501900 0000AAAA  .........P....**

DRIP : remote update - Never heard of this vlan
DRiP attempts to resolve any conflicts when it hears of a new VLAN. The value action = 1 means to notify the local platform of change in state:
DRIP : resolve remote for vlan 20 in VLAN0
DRIP : resolve remote - action = 1
The local platform is notified of change in state:
DRIP Change notification active vlan 20
Another new VLAN ID was received in the packet:
DRIP : resolve remote for vlan 1003 in Vlan0
No action is required:
DRIP : resolve remote - action = 0
Thirty seconds have expired, and DRiP sends its local database entries to all its trunk ports:

debug eigrp fsm

Use the debug eigrp fsm privileged EXEC command to display debugging information about Enhanced Interior Gateway Routing Protocol (EIGRP) feasible successor metrics (FSM). The no form of this command disables debugging output.

debug eigrp fsm
no debug eigrp fsm
Syntax Description

This command has no arguments or keywords.

Usage Guidelines

This command helps you observe EIGRP feasible successor activity and to determine whether route updates are being installed and deleted by the routing process.

Examples

The following is sample output from the debug eigrp fsm command:
Router# debug eigrp fsm
DUAL: dual_rcvupdate(): 172.25.166.0 255.255.255.0 via 0.0.0.0 metric 750080/0

DUAL: RT installed 172.25.166.0 255.255.255.0 via 0.0.0.0
DUAL: dual_rcvupdate(): 192.168.4.0 255.255.255.0 via 0.0.0.0 metric 4294967295/
4294967295
DUAL: Find FS for dest 192.168.4.0 255.255.255.0. FD is 2249216, RD is 2249216
DUAL:   0.0.0.0 metric 4294967295/4294967295not found Dmin is 4294967295
DUAL: Dest 192.168.4.0 255.255.255.0 not entering active state.
DUAL: Removing dest 192.168.4.0 255.255.255.0, nexthop 0.0.0.0
DUAL: No routes. Flushing dest 192.168.4.0 255.255.255.0
In the first line, DUAL stands for diffusing update algorithm. It is the basic mechanism within EIGRP that makes the routing decisions. The next three fields are the Internet address and mask of the destination network and the address through which the update was received. The metric field shows the metric stored in the routing table and the metric advertised by the neighbor sending the information. "Metric... inaccessible" usually means that the neighbor router no longer has a route to the destination, or the destination is in hold-down.

In the following output, EIGRP is attempting to find a feasible successor for the destination. Feasible successors are part of the DUAL loop avoidance methods. The FD field contains more loop avoidance state information. The RD field is the reported distance, which is the metric used in update, query or reply packets.

The indented line with the "not found" message means a feasible successor (FS) was not found for 192.168.4.0 and EIGRP must start a diffusing computation. This means it begins to actively probe (sends query packets about destination 192.168.4.0) the network looking for alternate paths to 192.164.4.0.
DUAL: Find FS for dest 192.168.4.0 255.255.255.0. FD is 2249216, RD is 2249216
DUAL:   0.0.0.0 metric 4294967295/4294967295not found Dmin is 4294967295
The following output indicates the route DUAL successfully installed into the routing table:
DUAL: RT installed 172.25.166.0 255.255.255.0 via 0.0.0.0
The following output shows that no routes were discovered to the destination and the route information is being removed from the topology table:
DUAL: Dest 192.168.4.0 255.255.255.0 not entering active state.
DUAL: Removing dest 192.168.4.0 255.255.255.0, nexthop 0.0.0.0
DUAL: No routes. Flushing dest 192.168.4.0 255.255.255.0

       AS 109, Flags 0x0, Seq 2, Ack 0
The output shows transmission and receipt of Enhanced Interior Gateway Routing Protocol (EIGRP) packets. These packet types may be HELLO, UPDATE, REQUEST, QUERY, or REPLY packets. The sequence and acknowledgment numbers used by the EIGRP reliable transport algorithm are shown in the output. Where applicable, the network layer address of the neighboring router is also included.

Table 45 describes significant fields in the output.

Table 45 debug eigrp packet Command Field Descriptions

Field

Description

EIGRP:

EIGRP packet information.

AS n

Autonomous system number.

Flags nxn

A flag of 1 means the sending router is indicating to the receiving router that this is the first packet it has sent to the receiver.

A flag of 2 is a multicast that should be conditionally received by routers that have the conditionally-receive (CR) bit set. This bit gets set when the sender of the multicast has previously sent a sequence packet explicitly telling it to set the CR bit.

HELLO

Hello packets are the neighbor discovery packets. They are used to determine whether neighbors are still alive. As long as neighbors receive the hello packets the router is sending, the neighbors validate the router and any routing information sent. If neighbors lose the hello packets, the receiving neighbors invalidate any routing information previously sent. Neighbors also transmit hello packets.

The FRF.4/Q.933 specification describes a state machine for call control. The signaling code implements the state machine. The debug statements display the actual event and state combinations.

The Frame Relay switched virtual circuit (SVC) signaling subsystem is an independent software module. When used with the debug frame-relay networklayerinterface command, the debug frame-relay callcontrol command provides a better understanding of the call setup and teardown sequence. The debug frame-relay networklayerinterface command provides the details of the interactions between the signaling subsystem on the router and the Frame Relay subsystem.

Examples

The following state changes can be observed during a call setup on the calling party side. The debug frame-relay networklayerinterface command shows the following state changes or transitions:
STATE_NULL -> STATE_CALL_INITIATED -> STATE_CALL_PROCEEDING->STATE_ACTIVE 
The following messages are samples of output generated during a call setup on the calling side:
6d20h: U0_SetupRequest: Serial0
6d20h: L3SDL: Ref: 1, Init: STATE_NULL, Rcvd: SETUP_REQUEST, Next: STATE_CALL_INITIATED 
6d20h: U1_CallProceeding: Serial0

debug frame-relay events

Use the debug frame-relay events privileged EXEC command to display debugging information about Frame Relay ARP replies on networks that support a multicast channel and use dynamic addressing. The no form of this command disables debugging output.

debug frame-relay events
no debug frame-relay events
Syntax Description

This command has no arguments or keywords.

Usage Guidelines

This command is useful for identifying the cause of end-to-end connection problems during the installation of a Frame Relay network or node.

Note Because the debug frame-relay events command does not generate much output, you can use it at any time, even during periods of heavy traffic, without adversely affecting other users on the system.

Examples

The following is sample output from the debug frame-relay events command:
Router# debug frame-relay events
Serial2(i): reply rcvd 172.16.170.26 126
Serial2(i): reply rcvd 172.16.170.28 128
Serial2(i): reply rcvd 172.16.170.34 134
Serial2(i): reply rcvd 172.16.170.38 144
Serial2(i): reply rcvd 172.16.170.41 228
Serial2(i): reply rcvd 172.16.170.65 325
As the output shows, debug frame-relay events returns one specific message type. The first line, for example, indicates that IP address 172.16.170.26 sent a Frame Relay ARP reply; this packet was received as input on the Serial2 interface. The last field (126) is the data-link connection identifier (DLCI) to use when communicating with the responding router.

Use the debug frame-relay informationelements privileged EXEC command to display information about Frame Relay layer 3 (network layer) information element parsing and construction. The no form of this command disables debugging output.

debug frame-relay informationelements
no debug frame-relay informationelements
Syntax Description

This command has no arguments or keywords.

Usage Guidelines

Within the FRF.4/Q.933 signaling specification, messages are divided into subunits called information elements. Each information element defines parameters specific to the call. These parameters can be values configured on the router, or values requested from the network.

The debug frame-relay informationelements command shows the signaling message in hexadecimal. Use this command to determine parameters being requested and granted for a call.

Note Use the debug frame-relay informationelements command when the debug frame-relay callcontrol command offers no clues as to why calls are not being set up.

Caution The debug frame-relay informationelements command displays a large amount of information in bytes. You must be familiar with FRF.4/Q.933 to decode the information contained within the debug output.

Examples

The following is sample output from the debug frame-relay informationelements command. In this example, each information element has a length associated with it. For those with odd-numbered lengths, only the specified bytes are valid, and the extra byte is invalid. For example, in the message "Call Ref, length: 3, 0x0200 0x0100," only "02 00 01" is valid, the last "00" is invalid.

Command History

Release

Modification

10.0

This command was introduced.

Usage Guidelines

The debug frame-relay ip tcp header-compression command shows the control packets that are passed to initialize IP header compression (IPHC) on a permanent virtual circuit (PVC). For Cisco IPHC, typically two packets are passed: one sent and one received per PVC. (Inverse Address Resolution Protocol (InARP) packets are sent on PVCs that do not have a mapping defined between a destination protocol address and the data-link connection identifier (DLCI) or Frame Relay PVC bundle that connects to the destination address.)

Debug messages are displayed only if the IPHC control protocol is renegotiated (for an interface or PVC state change or for a configuration change).

Examples

The following is sample output from the debug frame-relay ip tcp header-compression command when Cisco IPHC is configured in the IPHC profile:
Router# debug frame-relay ip tcp header-compression
*Nov 14 09:22:07.991: InARP REQ: Tx compr_flags 43 *Nov 14 09:22:08.103: InARP RSP: Rx 
compr_flags: 43
Table 50 describes the significant fields shown in the display.

Table 50 debug frame-relay ip tcp header-compression Field Descriptions

Field

Description

InARP REQ: Tx

Indicates that an InARP request was sent or received. Following are the possible values:

•InARP REQ Tx—An InARP request was sent.

•InARP REQ Rx—An InARP request was received.

InARP RSP: Rx

Indicates that an InARP response was sent or received. Following are the possible values:

•InARP REQ Tx—An InARP response was sent.

•InARP REQ Rx—An InARP response was received.

compr_flags: 43

Compression flags that Frame Relay peers use to negotiate Cisco IPHC options. It consists of a bit mask, and the number is displayed in hexadecimal format. Following are the bits:

•0x0001—TCP IPHC

•0x0002—RTP IPHC

•0x0004—Passive TCP compression

•0x0008—Passive RTP compression

•0x0040—Frame Relay IPHC options

debug frame-relay lapf

Use the debug frame-relay lapf privileged EXEC command to display Frame Relay switched virtual circuit (SVC) layer 2 information. The no form of this command disables debugging output.

debug frame-relay lapf
no debug frame-relay lapf
Syntax Description

This command has no arguments or keywords.

Usage Guidelines

Use the debug frame-relay lapf command to troubleshoot the data-link control portion of layer 2 that runs over data-link connection identifier (DLCI) 0. Use this command only if you have a problem bringing up layer 2. You can use the show interface serial command to determine the status of layer 2. If it shows a Link Access Procedure, Frame Relay (LAPF) state of down-layer 2 has a problem.

Examples

The following is sample output from the debug frame-relay lapf command. In this example, a line being brought up indicates an exchange of set asynchronous balanced mode extended (SAMBE) and unnumbered acknowledgment (UA) commands. A SABME is initiated by both sides, and a UA is the response. Until the SABME gets a UA response, the line is not declared to be up. The p/f value indicates the poll/final bit setting. TX means send, and RX means receive.
1w0d# debug frame-relay lapf
1w0d: *LAPF Serial0 TX -> SABME Cmd p/f=1 
1w0d: *LAPF Serial0 Enter state 5
1w0d: *LAPF Serial0 RX <- UA Rsp p/f=1
1w0d: *LAPF Serial0 lapf_ua_5
1w0d: *LAPF Serial0 Link up!
1w0d: *LAPF Serial0 RX <- SABME Cmd p/f=1 
1w0d: *LAPF Serial0 lapf_sabme_78
1w0d: *LAPF Serial0 TX -> UA Rsp p/f=1
In the following example, a line in an up LAPF state should see a steady exchange of RR (receiver ready) messages. TX means send, RX means receive, and N(R) indicates the receive sequence number.
1w0d# debug frame-relay lapf
1w0d: *LAPF Serial0 T203 expired, state = 7 
1w0d: *LAPF Serial0 lapf_rr_7
1w0d: *LAPF Serial0 TX -> RR Rsp p/f=1, N(R)= 3 
1w0d: *LAPF Serial0 RX <- RR Cmd p/f=1, N(R)= 3 
1w0d: *LAPF Serial0 lapf_rr_7
1w0d: *LAPF Serial0 TX -> RR Rsp p/f=1, N(R)= 3 
1w0d: *LAPF Serial0 RX <- RR Cmd p/f=1, N(R)= 3 
1w0d: *LAPF Serial0 lapf_rr_7
debug frame-relay lmi

Use the debug frame-relay lmi privileged EXEC command to display information on the local management interface (LMI) packets exchanged by the router and the Frame Relay service provider. The no form of this command disables debugging output.

debug frame-relay lmi [interface name]
no debug frame-relay lmi [interface name]
Syntax Description

interface name

(Optional) Name of interface.

Usage Guidelines

You can use this command to determine whether the router and the Frame Relay switch are sending and receiving LMI packets properly.

Note Because the debug frame-relay lmi command does not generate much output, you can use it at any time, even during periods of heavy traffic, without adversely affecting other users on the system.

Examples

The following is sample output from the debug frame-relay lmi command:

The first four lines describe an LMI exchange. The first line describes the LMI request the router has sent to the switch. The second line describes the LMI reply the router has received from the switch. The third and fourth lines describe the response to this request from the switch. This LMI exchange is followed by two similar LMI exchanges. The last six lines consist of a full LMI status message that includes a description of the router's two permanent virtual circuits (PVCs).

Table 51 describes significant fields in the first line of the debug frame-relay lmi output.

debug frame-relay networklayerinterface

Use the debug frame-relay networklayerinterface privileged EXEC command to display Network Layer Interface (NLI) information. The no form of this command disables debugging output.

debug frame-relay networklayerinterface
no debug frame-relay networklayerinterface
Syntax Description

This command has no arguments or keywords.

Usage Guidelines

The Frame Relay SVC signaling subsystem is decoupled from the rest of the router code by means of the Network Layer Interface intermediate software layer.

The debug frame-relay networklayerinterface command shows what happens within the network layer interface when a call is set up or torn down. All output that contains an NL relate to the interaction between the Q.933 signaling subsystem and the Network Layer Interface.

Note The debug frame-relay networklayerinterface command has no significance to anyone who is not familiar with the inner workings of the Cisco IOS software. This command is typically used by service personnel to debug problem situations.

Examples

The following is sample output from the debug frame-relay networklayerinterface command. This example displays the output generated when a call is set up. The second example shows the output generated when a call is torn down.

STATE_NL_NULL

Call in initial state—no call exists.

STATE_L3_CALL_REQ

Setup message sent out and waiting for a reply. This is the state the network layer state machine transitions to when a call request is received from Layer 3 but no confirmation has been received from the network.

NL_CALL_CNF

Message sent from Q.933 signaling subsystem to the Network Layer Interface asking that internal resources be allocated for the call.

STATE_L3_CALL_CNF

Q.933 state indicating that the call is active. After the network confirms a call request using a connect message, the Q.933 state machine transitions to this state.

STATE_NL_CALL_CNF

Internal software state indicating software resources are assigned and the call is up. After Q.933 transitions to the STATE_L3_CALL_CNF state, it sends an NL_CALL_CNF message to the network layer state machine, which then transitions to the STATE_NL_CALL_CNF state.

L3_CALL_REL_REQ

Internal request to release the call.

STATE_L3_CALL_REL_REQ

Internal software state indicating the call is in the process of being released. At this point, the Q.933 subsystem is told that the call is being released and a disconnect message goes out for the Q.933 subsystem.

NL_REL_CNF

Indication from the Q.933 signaling subsystem that the signaling subsystem is releasing the call. After receiving a release complete message from the network indicating that the release process is complete, the Q.933 subsystem sends an NL_REL_CNF event to the network layer subsystem.

Command

Description

debug frame-relay callcontrol

Displays Frame Relay layer 3 (network layer) call control information.

debug frame-relay packet

Use the debug frame-relay packet privileged EXEC command to display information on packets that have been sent on a Frame Relay interface. The no form of this command disables debugging output.

debug frame-relay packet [interface name [dlci value]]
no debug frame-relay packet [interface name [dlci value]]
Syntax Description

interface name

(Optional) Name of interface or subinterface.

dlci value

(Optional) Data-link connection indentifier (DLCI) decimal value.

Usage Guidelines

This command helps you analyze the packets that are sent on a Frame Relay interface. Because the debug frame-relay packet command generates large amounts of output, only use it when traffic on the Frame Relay network is less than 25 packets per second. Use the options to limit the debugging output to a specific DLCI or interface.

To analyze the packets received on a Frame Relay interface, use the debug frame-relay command.

Examples

The following is sample output from the debug frame-relay packet command:

The debug frame-relay packet output consists of groups of output lines; each group describes a Frame Relay packet that has been sent. The number of lines in the group can vary, depending on the number of data link connection identifiers (DLCIs) on which the packet was sent. For example, the first two pairs of output lines describe two different packets, both of which were sent out on a single DLCI. The last three lines describe a single Frame Relay packet that was sent out on two DLCIs.

Table 55 describes significant fields shown in the first pair of output lines.

Table 55 Debug Frame-Relay Packet Field Descriptions

Field

Description

Serial0:

Interface that has sent the Frame Relay packet.

broadcast = 1

Destination of the packet. Possible values include the following:

•broadcast = 1—Broadcast address

•broadcast = 0—Particular destination

•broadcast search—Searches all Frame Relay map entries for this particular protocol that include the keyword broadcast.

link 809B

Link type, as documented in the debug frame-relay command.

addr 65535.255

Destination protocol address for this packet. In this case, it is an AppleTalk address.

Serial0(o):

(o) indicates that this is an output event.

DLCI 500

Decimal value of the DLCI.

type 809B

Packet type, as documented under debug frame-relay.

size 24

Size of this packet (in bytes).

The following lines describe a Frame Relay packet sent to a particular address; in this case AppleTalk address 10.2:
Serial0: broadcast - 0, link 809B, addr 10.2
Serial0(o):DLCI 100 type 809B size 104
The following lines describe a Frame Relay packet that went out on two different DLCIs, because two Frame Relay map entries were found:
Serial0: broadcast search
Serial0(o):DLCI 300 type 809B size 24
Serial0(o):DLCI 400 type 809B size 24
The following lines do not appear. They describe a Frame Relay packet sent to a true broadcast address.
Serial1: broadcast search
Serial1(o):DLCI 400 type 800 size 288
debug frame-relay ppp

Use the debug frame-relay ppp privileged EXEC command to display debugging information. To disable debugging output, use the no form of this command.

debug frame-relay ppp
no debug frame-relay ppp
Syntax Description

This command has no arguments or keywords.

Usage Guidelines

Displays error messages for link states and LMI status changes for PPP over Frame Relay sessions.

To debug process-switched packets, use the debug frame-relay packet and/or debug ppp packet commands. To analyze the packets that have been sent on a Frame Relay interface, use the debug frame-relay packet command.

The debug frame-relay ppp command is generated from process level switching only and is not CPU intensive.

Examples

Figure 32 shows output from the debug frame-relay ppp command where the encapsulation failed for VC 100.

Indicates that key Q.931 events that occur when placing an H.323 call from one gateway to another will be displayed.

Command History

Release

Modification

11.3(6)NA2

This command was introduced.

Usage Guidelines

Both versions of the debug H225 command display information about H.225 messages. H.225 messages are used to exchange RAS information between gateways and gatekeepers as well as to exchange Q.931 information between gateways.

The debug h225 events command displays key Q.931 events that occur when placing an H.323 call from one gateway to another. Q.931 events are carried in H.225 messages. This command enables you to monitor Q.931 state changes such as setup, alert, connected, and released.

Note Although the debug information includes the hexadecimal output of the entire H.225 message, only the key state changes are decoded.

The debug h225 asn1 command displays the ASN.1 contents of any H.225 message sent or received that contains ASN.1 content. Not all H.225 messages contain ASN.1 content. Some messages contain both Q.931 information and ASN.1 information; if you enter this command, only ASN.1 information will be displayed.

Examples

The following sample display for the debug h225 events command shows a call being placed from gateway GW13 to gateway GW14. Before the call was placed, the gateway exchanged RAS messages with the gatekeeper. Because RAS messages do not contain Q.931 information, these messages do not appear in this output.

The following output shows the same call being placed from gateway GW13 to gateway GW14 using the debug h225 asn1 command. The output is very long but you can track the following information:

•The admission request to the gatekeeper.

•The admission confirmation from the gatekeeper.

•The ASN.1 portion of the H.225/Q.931 setup message from the calling gateway to the called gateway.

•The ASN.1 portion of the H.225/Q.931 setup response from the called gateway, indicating that the call has proceeded to alerting state.

•The ASN.1 portion of the H.225/Q.931 message from the called gateway, indicating that the call has been connected.

•The ASN.1 portion of the H.225/Q.931 message from the called gateway, indicating that the call has been released.

•The ANS.1 portion of the H.225 RAS message from the calling gateway to the gatekeeper, informing it that the call has been disengaged.

•The ASN.1 portion of the H.225 RAS message from the gatekeeper to the calling gateway, confirming the disengage request.

•The ASN.1 portion of the H.225/Q.931 release complete message sent from the called gateway to the calling gateway.

Usage Guidelines

Use the debug ip auth-proxy command to display authentication proxy activity. Refer to the Examples section for more information about the debug options.

Note The function-trace debugging information provides low-level software information for Cisco technical support representatives. No output examples are provided for this keyword option.

Examples

The following examples illustrates the output of the debug ip auth-proxy command. In these examples, debugging is on for object creations, object deletions, HTTP, and TCP.

In this example, the client host at 192.168.201.1 is attempting to make an HTTP connection to the web server located at 192.168.21.1. The HTTP debugging information is on for the authentication proxy. The output shows that the router is setting up an authentication proxy entry for the login request:
00:11:10: AUTH-PROXY creates info:
cliaddr - 192.168.21.1, cliport - 36583
seraddr - 192.168.201.1, serport - 80
ip-srcaddr 192.168.21.1
pak-srcaddr 0.0.0.0 
Following a successful login attempt, the debugging information shows the authentication proxy entries created for the client. In this example, the client is authorized for SMTP (port 25), FTP data (port 20), FTP control (port 21), and Telnet (port 23) traffic. The dynamic ACL entries are included in the display.

The following example shows the timer information for a dynamic ACL entry. All times are expressed in milliseconds. The first laststart is the time that the ACL entry is created relative to the start up time of the router. The lastref is the time of the last packet to hit the dynamic ACL relative to the start up time of the router. The exptime is the next expected expiration time for the dynamic ACL. The delta indicates the remaining time before the dynamic ACL expires. After the timer expires, the debugging information includes a message indicating that the ACL and associated authentication proxy information for the client have been removed.
