debug lane config

To display information about a LANE configuration server, use the debug lane config privileged EXEC command. The no form of this command disables debugging output.

debug lane config {all | events | packets}
no debug lane config {all | events | packets}
Syntax Description

all

Displays all debug messages related to the LANE configuration server. The output includes both the events and packets types of output.

events

Displays only messages related to significant LANE configuration server events.

packets

Displays information on each packet sent or received by the LANE configuration server.

Usage Guidelines

The debug lane config output is intended to be used primarily by a Cisco technical support representative.

Examples

The following is sample output from the debug lane config all command when an interface with LECS, an LES/BUS, and an LEC is shut down:
Router# debug lane config all

debug lane server

To display information about a LANE server, use the debug lane server privileged EXEC command. The no form of this command disables debugging output.

debug lane server [interface interface]
no debug lane server [interface interface]
Syntax Description

interface interface

(Optional) Limits the debugging output to messages relating to a specific interface or subinterface. If you use this command multiple times with different interfaces, the last interface entered is the one used to filter debug messages.

Usage Guidelines

The debug lane server command output is intended to be used primarily by a Cisco technical support representative. The debug lane server command can generate a substantial amount of output. Specify a subinterface to decrease the amount of output and focus on the information you need.

Examples

The following is sample output from the debug lane server command when an interface with LECS, LES/BUS, and LEC is shut down:

debug lane signaling

To display information about LANE Server (LES) and BUS switched virtual circuits (SVCs), use the debug lane signaling privileged EXEC command. The no form of this command disables debugging output.

debug lane signaling [interface interface]
no debug lane signaling [interface interface]
Syntax Description

interface interface

(Optional) Limits the debugging output to messages relating to a specific interface or subinterface. If you use this command multiple times with different interfaces, the last interface entered is the one used to filter debug messages.

Usage Guidelines

The debug lane signaling command output is intended to be used primarily by a Cisco technical support representative. The debug lane signaling command can generate a substantial amount of output. Specify a subinterface to decrease the amount of output and focus on the information you need.

debug lapb

To display all traffic for interfaces using Link Access Procedure, Balanced (LAPB) encapsulation, use the debug lapb privileged EXEC command. The no form of this command disables debugging output.

debug lapb
no debug lapb
Syntax Description

This command has no arguments or keywords.

Usage Guidelines

This command displays information on the X.25 Layer 2 protocol. It is useful to users familiar with the LAPB protocol.

You can use the debug lapb command to determine why X.25 interfaces or LAPB connections are going up and down. It is also useful for identifying link problems, as evidenced when the show interfaces EXEC command displays a high number of rejects or frame errors over the X.25 link.

Caution Because the debug lapb command generates a substantial amount of output, use it when the aggregate of all LAPB traffic on X.25 and LAPB interfaces is fewer than five frames per second.

Examples

The following is sample output from the debug lapb command (the numbers 1 through 7 at the top of the display have been added in order to aid documentation):
1         2   3    4     5    6    7
Serial0: LAPB I CONNECT (5) IFRAME P 2 1
Serial0: LAPB O REJSENT (2) REJ F 3
Serial0: LAPB O REJSENT (5) IFRAME 0 3
Serial0: LAPB I REJSENT (2) REJ (C) 7
Serial0: LAPB I DISCONNECT (2) SABM P
Serial0: LAPB O CONNECT (2) UA F
Serial0: LAPB O CONNECT (5) IFRAME 0 0
Serial0: LAPB T1 CONNECT 357964 0
Each line of output describes a LAPB event. There are two types of LAPB events: frame events (when a frame enters or exits the LAPB) and timer events. In the sample output, the last line describes a timer event; all of the other lines describe frame events. Table 117 describes the first seven fields.

Table 117 debug lapb Field Descriptions

Field

Description

First field (1)

Interface type and unit number reporting the frame event.

Second field (2)

Protocol providing the information.

Third field (3)

Frame event type. Possible values are as follows:

•I—Frame input

•O—Frame output

•T1—T1 timer expired

•T3—Interface outage timer expired

•T4—Idle link timer expired

Fourth field (4)

State of the protocol when the frame event occurred. Possible values are as follows:

•BUSY (RNR frame received)

•CONNECT

•DISCONNECT

•DISCSENT (disconnect sent)

•ERROR (FRMR frame sent)

•REJSENT (reject frame sent)

•SABMSENT (SABM frame sent)

Fifth field (5)

In a frame event, this value is the size of the frame (in bytes). In a timer event, this value is the current timer value (in milliseconds).

Sixth field (6)

In a frame event, this value is the frame type name. Possible values for frame type names are as follows:

•DISC—Disconnect

•DM—Disconnect mode

•FRMR—Frame reject

•IFRAME—Information frame

•ILLEGAL—Illegal LAPB frame

•REJ—Reject

•RNR—Receiver not ready

•RR—Receiver ready

•SABM—Set asynchronous balanced mode

•SABME—Set asynchronous balanced mode, extended

•UA—Unnumbered acknowledgment

In a T1 timer event, this value is the number of retransmissions already attempted.

Seventh field (7)

(This field will not print if the frame control field is required to appear as either a command or a response, and that frame type is correct.)

This field is only present in frame events. It describes the frame type identified by the LAPB address and Poll/Final bit. Possible values are as follows:

•(C)—Command frame

•(R)—Response frame

•P—Command/Poll frame

•F—Response/Final frame

•/ERR—Command/Response type is invalid for the control field. An ?ERR generally means that the DTE/DCE assignments are not correct for this link.

•BAD-ADDR—Address field is neither Command nor Response

A timer event only displays the first six fields of debug lapb command output. For frame events, however, the fields that follow the sixth field document the LAPB control information present in the frame. Depending on the value of the frame type name shown in the sixth field, these fields may or may not appear. Descriptions of the fields following the first six fields follow.

After the Poll/Final indicator, depending on the frame type, three different types of LAPB control information can be printed.

For information frames, the value of the N(S) field and the N(R) field will be printed. The N(S) field of an information frame is the sequence number of that frame, so this field will rotate between 0 and 7 for (modulo 8 operation) or 0 and 127 (for modulo 128 operation) for successive outgoing information frames and (under normal circumstances) also will rotate for incoming information frame streams. The N(R) field is a "piggybacked" acknowledgment for the incoming information frame stream; it informs the other end of the link which sequence number is expected next.

RR, RNR, and REJ frames have an N(R) field, so the value of that field is printed. This field has exactly the same significance that it does in an information frame.

For the FRMR frame, the error information is decoded to display the rejected control field, V(R) and V(S) values, the Response/Command flag, and the error flags WXYZ.

In the following example, the output shows an idle link timer action (T4) where the timer expires twice on an idle link, with the value of T4 set to five seconds:
Serial2: LAPB T4 CONNECT 255748
Serial2: LAPB O CONNECT (2) RR P 5
Serial2: LAPB I CONNECT (2) RR F 5
Serial2: LAPB T4 CONNECT 260748
Serial2: LAPB O CONNECT (2) RR P 5
Serial2: LAPB I CONNECT (2) RR F 5
The next example shows an interface outage timer expiration (T3):
Serial2: LAPB T3 DISCONNECT 273284
The following example output shows an error condition when no DCE to DTE connection exists. Note that if a frame has only one valid type (for example, a SABM can only be a command frame), a received frame that has the wrong frame type will be flagged as a receive error (R/ERR in the following output). This feature makes misconfigured links (DTE-DTE or DCE-DCE) easy to spot. Other, less common errors will be highlighed too, such as a too-short or too-long frame, or an invalid address (neither command nor response).
Serial2: LAPB T1 SABMSENT 1026508 1
Serial2: LAPB O SABMSENT (2) SABM P
Serial2: LAPB I SABMSENT (2) SABM (R/ERR)
Serial2: LAPB T1 SABMSENT 1029508 2
Serial2: LAPB O SABMSENT (2) SABM P
Serial2: LAPB I SABMSENT (2) SABM (R/ERR)
The output in the next example shows the router is misconfigured and has a standard (modulo 8) interface connected to an extended (modulo 128) interface. This condition is indicated by the SABM balanced mode and SABME balanced mode extended messages appearing on the same interface.
Serial2: LAPB T1 SABMSENT 1428720 0
Serial2: LAPB O SABMSENT (2) SABME P
Serial2: LAPB I SABMSENT (2) SABM P
Serial2: LAPB T1 SABMSENT 1431720 1
Serial2: LAPB O SABMSENT (2) SABME P
Serial2: LAPB I SABMSENT (2) SABM P

debug lex rcmd

To debug LAN Extender remote commands, use the debug lex rcmd privileged EXEC command. The no form of this command disables debugging output.

debug lex rcmd
no debug lex rcmd
Syntax Description

This command has no arguments or keywords.

Examples

The following is sample output from the debug lex rcmd command:
Router# debug lex rcmd
LEX-RCMD: "shutdown" command received on unbound serial interface- Serial0
LEX-RCMD: Lex0: "inventory" command received
Rcvd rcmd: FF 03 80 41 41 13 00 1A 8A 00 00 16 01 FF 00 00
Rcvd rcmd: 00 02 00 00 07 5B CD 15 00 00 0C 01 15 26
LEX-RCMD: ACK or response received on Serial0 without a corresponding ID
LEX-RCMD: REJ received
LEX-RCMD: illegal CODE field received in header: <number>
LEX-RCMD: illegal length for Lex0: "lex input-type-list"
LEX-RCMD: Lex0 is not bound to a serial interface
LEX-RCMD: encapsulation failure
LEX-RCMD: timeout for Lex0: "lex priority-group" command
LEX-RCMD: re-transmitting Lex0: "lex priority-group" command
LEX-RCMD: lex_setup_and_send called with invalid parameter
LEX-RCMD: bind occurred on shutdown LEX interface
LEX-RCMD: Serial0- No free Lex interface found with negotiated MAC address 0000.0c00.d8db
LEX-RCMD: No active Lex interface found for unbind
The following output indicates that a LAN Extender remote command packet was received on a serial interface that is not bound to a LAN Extender interface:
LEX-RCMD: "shutdown" command received on unbound serial interface- Serial0
This message can occur for any of the LAN Extender remote commands. Possible causes of this message are as follows:

•FLEX state machine software error

•Serial line momentarily goes down, which is detected by the host but not by FLEX

The following output indicates that a LAN Extender remote command response has been received. The hexadecimal values are for internal use only.
LEX-RCMD: Lex0: "inventory" command received
Rcvd rcmd: FF 03 80 41 41 13 00 1A 8A 00 00 16 01 FF 00 00
Rcvd rcmd: 00 02 00 00 07 5B CD 15 00 00 0C 01 15 26
The following output indicates that when the host router originates a LAN Extender remote command to FLEX, it generates an 8-bit identifier that is used to associate a command with its corresponding response:
LEX-RCMD: ACK or response received on Serial0 without a corresponding ID
This message could be displayed for any of the following reasons:

•FLEX was busy at the time that the command arrived and could not send an immediate response. The command timed out on the host router and then FLEX finally sent the response.

•Transmission error.

•Software error.

Possible responses to Config-Request are Config-ACK, Config-NAK, and Config-Rej. The following output shows that some of the options in the Config-Request are not recognizable or are not acceptable to FLEX due to transmission errors or software errors:
LEX-RCMD: REJ received
The following output shows that a LAN Extender remote command response was received but that the CODE field in the header was incorrect:
LEX-RCMD: illegal CODE field received in header: <number>
The following output indicates that a LAN Extender remote command response was received but that it had an incorrect length field. This message can occur for any of the LAN Extender remote commands.
LEX-RCMD: illegal length for Lex0: "lex input-type-list"
The following output shows that a host router was about to send a remote command when the serial link went down:
LEX-RCMD: Lex0 is not bound to a serial interface
The following output shows that the serial encapsulation routine of the interface failed to encapsulate the remote command datagram because the LEX-NCP was not in the OPEN state. Due to the way the PPP state machine is implemented, it is normal to see a single encapsulation failure for each remote command that gets sent at bind time.
LEX-RCMD: encapsulation failure
The following output shows that the timer expired for the given remote command without having received a response from the FLEX device. This message can occur for any of the LAN Extender remote commands.
 LEX-RCMD: timeout for Lex0: "lex priority-group" command
This message could be displayed for any of the following reasons:

•FLEX too busy to respond

•Transmission failure

•Software error

The following output indicates that the host is resending the remote command after a timeout:
LEX-RCMD: re-transmitting Lex0: "lex priority-group" command
The following output indicates that an illegal parameter was passed to the lex_setup_and_send routine. This message could be displayed for due to a host software error.
LEX-RCMD: lex_setup_and_send called with invalid parameter
The following output is informational and shows when a bind occurs on a shutdown interface:
LEX-RCMD: bind occurred on shutdown LEX interface
The following output shows that the LEX-NCP reached the open state and a bind operation was attempted with the FLEX's MAC address, but no free LAN Extender interfaces were found that were configured with that MAC address. This output can occur when the network administrator does not configure a LAN Extender interface with the correct MAC address.
LEX-RCMD: Serial0- No free Lex interface found with negotiated MAC address 0000.0c00.d8db
The following output shows that the serial line that was bound to the LAN Extender interface went down and the unbind routine was called, but when the list of active LAN Extender interfaces was searched, the LAN Extender interface corresponding to the serial interface was not found. This output usually occurs because of a host software error.
LEX-RCMD: No active Lex interface found for unbind
debug list

To filter debugging information on a per-interface or per-access list basis, use the debug list privileged EXEC command. The no form of this command turns off the list filter.

debug list [list] [interface]
no debug list [list] [interface]
Syntax Description

list

(Optional) An access list number in the range from 1100 to 1199.

interface

(Optional) The nterface type. Allowed values are the following:

•channel—IBM Channel interface

•ethernet—IEEE 802.3

•fddi—ANSI X3T9.5

•null—Null interface

•serial—Serial

•tokenring—IEEE 802.5

•tunnel—Tunnel interface

Usage Guidelines

The debug list command is used with other debug commands for specific protocols and interfaces to filter the amount of debug information that is displayed. In particular, this command is designed to filter specific physical unit (PU) output from bridging protocols. The debug list command is supported with the following commands:

•debug llc2 errors

•debug llc2 packets

•debug llc2 state

•debug rif

•debug sdlc

•debug token ring

Note All debug commands that support access list filtering use access lists in the range from 1100 to 1199. The access list numbers shown in the examples are merely samples of valid numbers.

Examples

To use the debug list command on only the first of several LLC2 connections, use the show llc2 command to display the active connections:
Router# show llc2
SdllcVirtualRing2008 DTE: 4000.2222.22c7 4000.1111.111c 04 04 state NORMAL
SdllcVirtualRing2008 DTE: 4000.2222.22c8 4000.1111.1120 04 04 state NORMAL
SdllcVirtualRing2008 DTE: 4000.2222.22c1 4000.1111.1104 04 04 state NORMAL
Next, configure an extended bridging access list, numbered 1103, for the connection you want to filter:
access-list 1103 permit 4000.1111.111c 0000.0000.0000 4000.2222.22c7 0000.0000.0000 0xC 2 
eq 0x404
The convention for the LLC debug list command filtering is to use dmac = 6 bytes, smac = 6 bytes, dsap_offset = 12, and ssap_offset = 13.

Finally, you invoke the following debug commands:
Router# debug list 1103
Router# debug llc2 packet
LLC2 Packets debugging is on
for access list: 1103
To use the debug list command for SDLC connections, with the exception of address 04, create access list 1102 to deny the specific address and permit all others:
access-list 1102 deny 0000.0000.0000 0000.0000.0000 0000.0000.0000 0000.0000.0000 0xC 1 eq 
0x4
access-list 1102 permit 0000.0000.0000 0000.0000.0000 0000.0000.0000 0000.0000.0000
The convention is to use dmac = 0.0.0, smac = 0.0.0, and sdlc_frame_offset = 12.

Invoke the following debug commands:
Router# debug list 1102
Router# debug sdlc
SDLC link debugging is on
for access list: 1102
To enable SDLC debugging (or debugging for any of the other supported protocols) for a specific interface rather than for all interfaces on a router, use the following commands:
Router# debug list serial 0
Router# debug sdlc
SDLC link debugging is on
for interface: Serial0 
To enable Token Ring debugging between two MAC address, 0000.3018.4acd and 0000.30e0.8250, configure an extended bridging access list 1106:
access-list 1106 permit 0000.3018.4acd 8000.0000.0000 0000.30e0.8250 8000.0000.0000
access-list 1106 permit 0000.30e0.8250 8000.0000.0000 0000.3018.4acd 8000.0000.0000
Invoke the following debug commands:
Router# debug list 1106
Router# debug token ring
Token Ring Interface debugging is on
for access list: 1106 
To enable RIF debugging for a single MAC address, configure an access list 1109:
access-list 1109 permit permit 0000.0000.0000 ffff.ffff.ffff 4000.2222.22c6 0000.0000.0000
Invoke the following debug commands:
Router# debug list 1109
Router# debug rif
RIF update debugging is on
for access list: 1109

Syntax Description

This command has no arguments or keywords.

Examples

The following is sample output from the debug llc2 dynwind command:
Router# debug llc2 dynwind
LLC2/DW: BECN received! event REC_I_CMD, Window size reduced to 4
LLC2/DW: 1 consecutive I-frame(s) received without BECN
LLC2/DW: 2 consecutive I-frame(s) received without BECN
LLC2/DW: 3 consecutive I-frame(s) received without BECN
LLC2/DW: 4 consecutive I-frame(s) received without BECN
LLC2/DW: 5 consecutive I-frame(s) received without BECN
LLC2/DW: Current working window size is 5
In this example, the router receives a backward explicit congestion notification (BECN) and reduces the window size to four. After receiving five consecutive I frames without a BECN, the router increases the window size to five.
