Usage Guidelines
This command helps discover whether the MLD protocol activities are working correctly. In general, if MLD is not working, the router process never discovers that there is a host on the network that is configured to receive multicast packets.
The messages displayed by the debug ipv6 mld command show query and report activity received from other routers and hosts. Use this command in conjunction with debug ipv6 pim to display additional multicast activity, to learn more information about the multicast routing process, or to learn why packets are forwarded out of particular interfaces.
Examples
The following example enables debugging on MLD protocol activity:

|
Usage Guidelines
The debug ipv6 nat command can be used to troubleshoot NAT-PT translation issues. If no keywords are specified, debugging messages for all NAT-PT protocol translation events are displayed.
Note
By default, the network server sends the output from debug commands and system error messages to the console. To redirect debugging output, use the logging command options within global configuration mode. Destinations are the console, virtual terminals, internal buffer, and UNIX hosts running a syslog server.
Caution 
Because the
debug ipv6 nat command generates a substantial amount of output, use it only when traffic on the IPv6 network is low, so other activity on the system is not adversely affected.
Examples
The following example shows output for the debug ipv6 nat command:
00:06:06: IPv6 NAT: icmp src (3002::8) -> (192.168.124.8), dst (2001::2) ->

Table 192 describes the significant fields shown in the display.
Table 192 debug ipv6 nd Field Descriptions
Field
|
Description
|
13:22:40:
|
Indicates the time (hours:minutes:seconds) at which the ICMP neighbor discovery event occrred.
|
ICMPv6-ND
|
Indicates that a state change is occurring for an entry in the IPv6 neighbors cache.
|
STALE
|
Stale state. This state of an neighbor discovery cache entry used to be "reachable," but is now is "stale" due to the entry not being used. In order to use this address, the router must go through the neighbor discovery process in order to confirm reachability.
|
DELAY
|
Delayed state. Reachability for this ND cache entry is currently being reconfirmed. While in the delay state, upper-layer protocols may inform IPv6 that they have confirmed reachability to the entry. Therefore, there is no need to send a neighbor solicitation for the entry.
|
PROBE
|
Probe state. While in the probe state, if no confirmation is received from the upper-layer protocols about the reachability of the entry, a neighbor solicitation message is sent. The entry remains in the "probe" state until a neighbor advertisement message is received in response to the neighbor solicitation message.
|
Sending NS for...
|
Sending a neighbor solicitation message. In the example output, a neighbor solicitation message is sent on Fast Ethernet interface 0/0 to determine the link-layer address of 2000:0:0:3::2 on Fast Ethernet interface 0/0.
|
Received NA for...
|
Received a neighbor advertisement message. In the example output, a neighbor advertisement message is received from the address 2000:0:0:3::2 (the second address) that includes the link-layer address of 2000:0:0:3::2 (first address) from Ethernet interface 0/0.
|
REACH
|
Reachable state. An ND cache entry in this state is considered reachable, and the corresponding link-layer address can be used without needing to perform neighbor discovery on the address.
|
Received NS for...
|
Received neighbor solicitations. In the example output, the address FE80::203:A0FF:FED6:1400 (on Fast Ethernet interface 0/0) is trying to determine the link-local address of 2000:0:0:3::1.
|
Sending NA for...
|
Sending for neighbor advertisements. In the example output, a neighbor advertisement containing the link-layer address of 2000:0:0:3::1 (an address assigned to the Fast Ethernet interface 0/0 address) was sent.
|
DAD: FE80::1 is unique.
|
Duplicate address detection processing was performed on the unicast IPv6 address (a neighbor solicitation message was not received in response to a neighbor advertisement message that contained the unicast IPv6 address) and the address is unique.
|
3d19h:
|
Indicates time (days, hours) since the last reboot of the event occurring; 3d19h: indicates the time (since the last reboot) of the event occurring was 3 days and 19 hours ago.
|
DAD: duplicate link-local FE80::2 on Ethernet0/2, interface stalled
|
Duplicate address detection processing was performed on the link-local IPv6 address (the link-local address FE80::2 is used in the example). A neighbor advertisement message was received in response to a neighbor solicitation message that contained the link-local IPv6 address. The address is not unique, and the processing of IPv6 packets is disabled on the interface.
|
%IPV6-4-DUPLICATE: Duplicate address...
|
System error message indicating the duplicate address.
|
Received NA for 3000::4 on Ethernet0/3 from 3000::4
|
Duplicate address detection processing was performed on the global IPv6 address (the global address 3000::4 is used in the example). A neighbor advertisement message was received in response to a neighbor solicitation message that contained the global IPv6 address. The address is not unique and is not used.

Usage Guidelines
The debug ipv6 packet command is similar to the debug ip packet command, except that it is IPv6-specific.
Note
By default, the network server sends the output from debug commands and system error messages to the console. To redirect debug output, use the logging command options within global configuration mode. Destinations include the console, virtual terminals, internal buffer, and UNIX hosts running a syslog server. For complete information on debug commands and redirecting debug output, refer to the Cisco IOS Debug Command Reference.
IPv6 debugging information includes packets received, generated, and forwarded. Fast-switched packets do not generate messages. When an IPv6 access list is specified by using the access-list keyword and access-list-name argument, only packets matching the access list permit entries are displayed.
Caution 
Because the
debug ipv6 packet command generates a substantial amount of output, use it only when traffic on the IPv6 network is low, so other activity on the system is not adversely affected.
Examples
The following example shows output for the debug ipv6 packet command:
Router# debug ipv6 packet

|
Usage Guidelines
If no access list is specified using the optional access-list-name argument, information about all policy-matched and policy-routed packets is displayed.
After you configure IPv6 policy routing, use the debug ipv6 policy command to verify that IPv6 policy-based routing (PBR) is policy-routing packets normally. Policy routing looks at various parts of the packet and then routes the packet based on certain user-defined attributes in the packet. The debug ipv6 policy command helps you determine what policy routing is following. It displays information about whether a packet matches the criteria, and if so, the resulting routing information for the packet.
Do not use the debug ipv6 policy command unless you suspect a problem with IPv6 PBR policy routing.
Examples
The following example enables IPv6 policy routing packet activity. The output for this command is self-explanatory:
Router# debug ipv6 policy
00:02:38:IPv6 PBR:Ethernet0/0, matched src 2003::90 dst 2001:1000::1 protocol 58

Usage Guidelines
The debug ipv6 rip command is similar to the debug ip rip command, except that it is IPv6-specific.
Note
By default, the network server sends the output from debug commands and system error messages to the console. To redirect debug output, use the logging command options within global configuration mode. Destinations include the console, virtual terminals, internal buffer, and UNIX hosts running a syslog server. For complete information on debug commands and redirecting debug output, refer to the Cisco IOS Debug Command Reference.
Using this command without arguments enables IPv6 RIP debugging for RIP packets that are sent and received on all router interfaces. Using this command with arguments enables IPv6 RIP debugging for RIP packets that are sent and received only on the specified interface.
Caution 
Using this command on busy networks seriously degrades the performance of the router.
Examples
The following example shows output for the debug ipv6 rip command:
13:09:10:RIPng:Sending multicast update on Ethernet1/1 for as1_rip
13:09:10: src=FE80::203:E4FF:FE12:CC1D
13:09:10: dst=FF02::9 (Ethernet1/1)
13:09:10: sport=521, dport=521, length=32
13:09:10: command=2, version=1, mbz=0, #rte=1
13:09:10: tag=0, metric=1, prefix=::/0
13:09:28:RIPng:response received from FE80::202:FDFF:FE77:1E42 on Ethernet1/1 for as1_rip
13:09:28: src=FE80::202:FDFF:FE77:1E42 (Ethernet1/1)
13:09:28: sport=521, dport=521, length=32
13:09:28: command=2, version=1, mbz=0, #rte=1
13:09:28: tag=0, metric=1, prefix=2000:0:0:1:1::/80
The example shows two RIP packets; both are updates, known as "responses" in RIP terminology and indicated by a "command" value of 2. The first is an update sent by this router, and the second is an update received by this router. Multicast update packets are sent to all neighboring IPv6 RIP routers (all routers that are on the same links as the router sending the update, and that have IPv6 RIP enabled). An IPv6 RIP router advertises the contents of its routing table to its neighbors by periodically sending update packets over those interfaces on which IPv6 RIP is configured. An IPv6 router may also send "triggered" updates immediately following a routing table change. In this case the updates only includes the changes to the routing table. An IPv6 RIP router may solicit the contents of the routing table of a neighboring router by sending a Request (command =1) message to the router. The router will respond by sending an update (Response, command=2) containing its routing table. In the example, the received response packet could be a periodic update from the address FE80::202:FDFF:FE77:1E42 or a response to a RIP request message that was previously sent by the local router.
Table 194 describes the significant fields shown in the display.

13:19:37:IPv6RT0:Better next-hop for 2000:0:0:6::/64, [20/2]
The debug ipv6 routing command displays messages whenever the routing table changes. For example, the following message indicates that a route to the prefix 2000:0:0:1:1::/80 was added to the routing table at the time specified in the message.
13:18:43:IPv6RT0:Add 2000:0:0:1:1::/80 to table
The following message indicates that the prefix 2000:0:0:2::/64 was already in the routing table; however, a received advertisement provided a lower cost path to the prefix. Therefore, the routing table was updated with the lower cost path. (The [20/1] in the example is the administrative distance [20] and metric [1] of the better path.)
13:19:09:IPv6RT0:Better next-hop for 2000:0:0:2::/64, [20/1]

debug ipx packet
To display information about packets received, sent, and forwarded, use the debug ipx packet command in privileged EXEC mode. To disable debugging output, use the no form of this command.
debug ipx packet
no debug ipx packet
Syntax Description
This command has no arguments or keywords.
Command Modes
Privileged EXEC
Usage Guidelines
This command is useful for learning whether Internetwork Packet Exchange (IPX) packets are traveling over a router.
Note
In order to generate debug ipx packet information on all IPX traffic traveling over the router, you must first configure the router so that fast switching is disabled. Use the no ipx route-cache command on all interfaces on which you want to observe traffic. If the router is configured for IPX fast switching, only non fast-switched packets will produce output. When the IPX cache is invalidated or cleared, one packet for each destination is displayed as the cache is repopulated.
Examples
The following is sample output from the debug ipx packet command:
IPX: src=160.0260.8c4c.4f22, dst=1.0000.0000.0001, packet received
IPX: src=160.0260.8c4c.4f22, dst=1.0000.0000.0001,gw=183.0000.0c01.5d85,
The first line indicates that the router receives a packet from a Novell station (address 160.0260.8c4c.4f22); this trace does not indicate the address of the immediate router sending the packet to this router. In the second line, the router forwards the packet toward the Novell server (address 1.0000.0000.0001) through an immediate router (183.0000.0c01.5d85).
Table 195 describes the significant fields shown in the display.

debug ipx routing
To display information on Internetwork Packet Exchange (IPX) routing packets that the router sends and receives, use the debug ipx routing command in privileged EXEC mode. To disable debugging output, use the no form of this command.
debug ipx routing {activity | events}
no debug ipx routing {activity | events}
Syntax Description
activity
|
Displays messages relating to IPX routing activity.
|
events
|
Displays messages relating to IPX routing events.
|
Command Modes
Privileged EXEC
Usage Guidelines
Normally, a router or server sends out one routing update per minute. Each routing update packet can include up to 50 entries. If many networks exist on the internetwork, the router sends out multiple packets per update. For example, if a router has 120 entries in the routing table, it would send three routing update packets per update. The first routing update packet would include the first 50 entries, the second packet would include the next 50 entries, and the last routing update packet would include the last 20 entries.
Examples
The following is sample output from the debug ipx routing command:
Router# debug ipx routing
IPXRIP: update from 9999.0260.8c6a.1733
110801 in 1 hops, delay 2
IPXRIP: sending update to 12FF02:ffff.ffff.ffff via Ethernet 1

Syntax Description
activity
|
(Optional) Provides more detailed output of SAP packets, including displays of services in SAP packets.
|
events
|
(Optional) Limits amount of detailed output for SAP packets to those that contain interesting events.
|
Command Modes
Privileged EXEC
Usage Guidelines
Normally, a router or server sends out one SAP update per minute. Each SAP packet can include up to seven entries. If many servers are advertising on the network, the router sends out multiple packets per update. For example, if a router has 20 entries in the SAP table, it would send three SAP packets per update. The first SAP would include the first seven entries, the second SAP would include the next seven entries, and the last update would include the last six entries.
Obtain the most meaningful detail by using the debug ipx sap activity and the debug ipx sap events commands together.
Caution 
Because the
debug ipx sap command can generate a substantial amount of output, use it with caution on networks that have many interfaces and large service tables.
Examples
The following is sample output from the debug ipx sap command:
I SAP Response type 0x2 len 160 src:160.0000.0c00.070d dest:160.ffff.ffff.ffff(452)
type 0x4, "Hello2", 199.0002.0004.0006 (451), 2 hops
type 0x4, "Hello1", 199.0002.0004.0008 (451), 2 hops
IPXSAP: sending update to 160
O SAP Update type 0x2 len 96 ssoc:0x452 dest:160.ffff.ffff.ffff(452)
IPX: type 0x4, "Magnolia", 42.0000.0000.0001 (451), 2hops
The debug ipx sap command generates multiple lines of output for each SAP packet—a packet summary message and a service detail message.
The first line displays the internal router memory address of the packet. The technical support staff may use this information in problem debugging.

Usage Guidelines
Although the debug isdn event and the debug isdn q931 commands provide similar debug information, the information is displayed in a different format. If you want to see the information in both formats, enable both commands at the same time. The displays will be intermingled.
The ISDN events that can be displayed are Q.931 events (call setup and teardown of ISDN network connections).
Use the show dialer command to retrieve information about the status and configuration of the ISDN interface on the router.
Use the service timestamps debug datetime msec global configuration command to include the time with each message.
For more information on ISDN switch types, codes, and values, see Appendix B, "ISDN Switch Types, Codes, and Values."
Examples
The following is sample output from the debug isdn event command of call setup events for an outgoing call:
ISDN Event: Call to 415555121202
ISDN Event: Connected to 415555121202 on B1 at 64 Kb/s
The following shows sample debug isdn event output of call setup events for an incoming call. The values used for internal purposes are unpacked information elements. The values that follow the ISDN specification are an interpretation of the unpacked information elements.
received HOST_INCOMING_CALL
Bearer Capability i = 0x080010
Calling Party Number i = 0x0000, `415555121202'
IE out of order or end of `private' IEs --
Bearer Capability i = 0x8890
Calling Party Number i = 0x0083, `415555121202'
ISDN Event: Received a call from 415555121202 on B1 at 64 Kb/s
ISDN Event: Accepting the call
ISDN Event: Connected to 415555121202 on B1 at 64 Kb/s
The following is sample output from the debug isdn event command of call teardown events for a call that has been disconnected by the host side of the connection:
ISDN Event: Call to 415555121202 was hung up
The following is sample output from the debug isdn event command of a call teardown event for an outgoing or incoming call that has been disconnected by the ISDN interface on the router side:
ISDN Event: Hangup call to call id 0x8008

Usage Guidelines
The ISDN data link layer interface provided by the router conforms to the user interface specification defined by ITU-T recommendation Q.921. The debug isdn q921 command output is limited to commands and responses exchanged during peer-to-peer communication carried over the D channel. This debug information does not include data transmitted over the B channels that are also part of the router ISDN interface. The peers (data link layer entities and layer management entities on the routers) communicate with each other with an ISDN switch over the D channel.
Note
The ISDN switch provides the network interface defined by Q.921. This debug command does not display data link layer access procedures taking place within the ISDN network (that is, procedures taking place on the network side of the ISDN connection). Refer to Appendix B, "ISDN Switch Types, Codes, and Values," in the "ISDN Switch Types, Codes, and Values" document on Cisco.com for a list of the supported ISDN switch types.
A router can be the calling or called party of the ISDN Q.921 data link layer access procedures. If the router is the calling party, the command displays information about an outgoing call. If the router is the called party, the command displays information about an incoming call and the keepalives.
The debug isdn q921 command can be used with the debug isdn event, debug isdn q931, debug isdn q921 frame, and debug isdn q921 detail commands at the same time. The displays are intermingled.
Use the service timestamps debug datetime msec global configuration command to include the time with each message.
Examples
The following is example output for a single active data link connection (DLC). The debugs turned on are debug isdn q921, debug isdn q921 frame, and debug isdn q921 detail. In the debugs below, "Q921" followed by a colon (:) indicates that debug isdn q921 has been entered. "Q921" followed by the letter "f" indicates that debug isdn q921 frame has been entered. "Q921" followed by the letter "d" indicates that debug isdn q921 detail has been entered.
The following output shows that the L2 frame is received. The first two octets form the address field; the third octet forms the control field. The address field identifies the originator of a frame and whether it is a command or a response. The second octet of the address field identifies the DLC with which the frame is associated. The control field (third octet) contains the frame type code and sequence number information.
00:12:10:ISDN Q921d:isdn_from_driver_process:QUEUE_EVENT
00:12:10:ISDN Se1:15 Q921f:PBXb RX <- 0x0E03EF
The following output interprets the octet information. String "PBXb" indicates that the side receiving (RX) this frame is acting as a PBXb (as opposed to PBXa, which is the other possibility). This example also gives information about the type of frame received (SABMR), the associated DLC (1), the frame type code received from the control field (cntl=SABMR), and the sequence number (indicated by nbit, which is 0 in this case).
00:12:10:ISDN Se1:15 Q921:PBXb RX <- SABMR dlci=1 cntl=SABMR nbit=0
The following output shows information received from the driver (source_id of x200) showing an L2 frame (event x141). This results from the SABMR frame that was received from the peer PBX (v_bit and chan do not have any significance in this case).
00:12:10:ISDN Se1:15 Q921d:process_rxdata:Frame sent to L2
00:12:10:ISDN Q921d:isdn_from_driver_process:event_count 3
00:12:10:ISDN Se1:15 Q921d:dpnss_l2_main:source_id x200 event x141 v_bit x0 chan x0
The following output shows that DPNSS L2 for DLC 1 (chan 1) has received an SABMR frame (event x0) in the IDLE state (s_dpnss_idle):
00:12:10:ISDN Se1:15 Q921d:s_dpnss_idle:event x0 chan 1
The following output shows that for DLC 1 (chan 1 above), a UA frame (event x1) needs to be sent to the driver (dest x200):
00:12:10:ISDN Se1:15 Q921d:dpnss_l2_mail:dest x200 event x1 v_bit 1 chan 1 out_pkt
x630531A4
The following output shows that for DLC 1, a DL_EST_IND (event x201) needs to be sent to L3 (DUA in this case because of the backhauling) indicating that this DLC is now up (in RESET COMPLETE state):
00:12:10:ISDN Se1:15 Q921d:dpnss_l2_mail:dest x300 event x201 v_bit 1 chan 1 out_pkt x0
The following output shows that the L2 frame is transmitted (TX):
00:12:10:ISDN Q921d:isdn_l2d_srq_process:QUEUE_EVENT
00:12:10:ISDN Se1:15 Q921f:PBXb TX -> 0x0E0363
The following output shows that string "PBXb" is the side transmitting (TX) and that this frame is acting as PBX B. This example also gives information about the associated DLC (1), the frame type code transmitted from the control field (cntl=UA), and the sequence number (indicated by nbit, which is 0 in this case).

The first seven lines of this example indicate a Layer 2 link establishment.
The following lines indicate the message exchanges between the data link layer entity on the local router (user side) and the assignment source point (ASP) on the network side during the TEI assignment procedure. This assumes that the link is down and no TEI currently exists.
Jan 3 14:47:30.171: ISDN BR0: TX -> IDREQ ri = 31815 ai = 127
Jan 3 14:47:30.219: ISDN BR0: RX <- IDASSN ri = 31815 ai = 64
At 14:47:30.171, the local router data link layer entity sent an Identity Request message to the network data link layer entity to request a TEI value that can be used in subsequent communication between the peer data link layer entities. The request includes a randomly generated reference number (31815) to differentiate among user devices that request automatic TEI assignment and an action indicator of 127 to indicate that the ASP can assign any TEI value available. The ISDN user interface on the router uses automatic TEI assignment.
At 14:47:30.219, the network data link entity responds to the Identity Request message with an Identity Assigned message. The response includes the reference number (31815) previously sent in the request and TEI value (64) assigned by the ASP.
The following lines indicate the message exchanges between the layer management entity on the network and the layer management entity on the local router (user side) during the TEI check procedure:
Jan 3 14:47:30.227: ISDN BR0: RX <- IDCKRQ ri = 0 ai = 127
Jan 3 14:47:30.235: ISDN BR0: TX -> IDCKRP ri = 16568 ai = 64
At 14:47:30.227, the layer management entity on the network sends the Identity Check Request message to the layer management entity on the local router to check whether a TEI is in use. The message includes a reference number that is always 0 and the TEI value to check. In this case, an ai value of 127 indicates that all TEI values should be checked. At 14:47:30.227, the layer management entity on the local router responds with an Identity Check Response message indicating that TEI value 64 is currently in use.
The following lines indicate the messages exchanged between the data link layer entity on the local router (user side) and the data link layer on the network side to place the network side into modulo 128 multiple frame acknowledged operation. Note that the data link layer entity on the network side also can initiate the exchange.
Jan 3 14:47:30.223: ISDN BR0: TX -> SABMEp sapi = 0 tei = 64
Jan 3 14:47:30.239: ISDN BR0: RX <- UAf sapi = 0 tei = 64
At 14:47:30.223, the data link layer entity on the local router sends the SABME command with a SAPI of 0 (call control procedure) for TEI 64. At 14:47:30.239, the first opportunity, the data link layer entity on the network responds with a UA response. This response indicates acceptance of the command. The data link layer entity sending the SABME command may need to send it more than once before receiving a UA response.
The following lines indicate the status of the data link layer entities. Both are ready to receive I frames.
Jan 3 14:47:43.815: ISDN BR0: RX <- RRp sapi = 0 tei = 64 nr = 2
Jan 3 14:47:43.819: ISDN BR0: TX -> RRf sapi = 0 tei = 64 nr = 0
These I-frames are typically exchanged every 10 seconds (T203 timer).
The following is sample output from the debug isdn q921 command for an incoming call. It is an incoming SETUP message that assumes that the Layer 2 link is already established to the other side.

Table 201 describes the significant fields shown in the display.
Table 201 debug isdn q921 Field Descriptions
Field
|
Description
|
Jan 3 14:49:47.391
|
Indicates the date and time at which the frame was sent from or received by the data link layer entity on the router. The time is maintained by an internal clock.
|
TX
|
Indicates that this frame is being sent from the ISDN interface on the local router (user side).
|
RX
|
Indicates that this frame is being received by the ISDN interface on the local router from the peer (network side).
|
IDREQ
|
Indicates the Identity Request message type sent from the local router to the network (ASP) during the automatic TEI assignment procedure. This message is sent in a UI command frame. The SAPI value for this message type is always 63 (indicating that it is a Layer 2 management procedure) but it is not displayed. The TEI value for this message type is 127 (indicating that it is a broadcast operation).
|
ri = 31815
|
Indicates the Reference number used to differentiate between user devices requesting TEI assignment. This value is a randomly generated number from 0 to 65535. The same ri value sent in the IDREQ message should be returned in the corresponding IDASSN message. Note that a Reference number of 0 indicates that the message is sent from the network side management layer entity and a reference number has not been generated.
|
ai = 127
|
Indicates the Action indicator used to request that the ASP assign any TEI value. It is always 127 for the broadcast TEI. Note that in some message types, such as IDREM, a specific TEI value is indicated.
|
IDREM
|
Indicates the Identity Remove message type sent from the ASP to the user side layer management entity during the TEI removal procedure. This message is sent in a UI command frame. The message includes a reference number that is always 0, because it is not responding to a request from the local router. The ASP sends the Identity Remove message twice to avoid message loss.
|
IDASSN
|
Indicates the Identity Assigned message type sent from the ISDN service provider on the network to the local router during the automatic TEI assignment procedure. This message is sent in a UI command frame. The SAPI value for this message type is always 63 (indicating that it is a Layer 2 management procedure). The TEI value for this message type is 127 (indicating it is a broadcast operation).
|
ai = 64
|
Indicates the TEI value automatically assigned by the ASP. This TEI value is used by data link layer entities on the local router in subsequent communication with the network. The valid values are in the range from 64 to 126.
|
SABME
|
Indicates the set asynchronous balanced mode extended command. This command places the recipient into modulo 128 multiple frame acknowledged operation. This command also indicates that all exception conditions have been cleared. The SABME command is sent once a second for N200 times (typically three times) until its acceptance is confirmed with a UA response. For a list and brief description of other commands and responses that can be exchanged between the data link layer entities on the local router and the network, see ITU-T Recommendation Q.921.
|
sapi = 0
|
Identifies the service access point at which the data link layer entity provides services to Layer 3 or to the management layer. A SAPI with the value 0 indicates it is a call control procedure. Note that the Layer 2 management procedures such as TEI assignment, TEI removal, and TEI checking, which are tracked with the debug isdn q921 command, do not display the corresponding SAPI value; it is implicit. If the SAPI value were displayed, it would be 63.
|
tei = 64
|
Indicates the TEI value automatically assigned by the ASP. This TEI value will be used by data link layer entities on the local router in subsequent communication with the network. The valid values are in the range from 64 to 126.
|
IDCKRQ
|
Indicates the Identity Check Request message type sent from the ISDN service provider on the network to the local router during the TEI check procedure. This message is sent in a UI command frame. The ri field is always 0. The ai field for this message contains either a specific TEI value for the local router to check or 127, which indicates that the local router should check all TEI values. For a list and brief description of other message types that can be exchanged between the local router and the ISDN service provider on the network, see Appendix B, "ISDN Switch Types, Codes, and Values."
|
IDCKRP
|
Indicates the Identity Check Response message type sent from the local router to the ISDN service provider on the network during the TEI check procedure. This message is sent in a UI command frame in response to the IDCKRQ message. The ri field is a randomly generated number from 0 to 65535. The ai field for this message contains the specific TEI value that has been checked.
|
UAf
|
Confirms that the network side has accepted the SABME command previously sent by the local router. The final bit is set to 1.
|
INFOc
|
Indicates that this is an Information command. It is used to transfer sequentially numbered frames containing information fields that are provided by Layer 3. The information is transferred across a data-link connection.
|
INFORMATION pd = 8 callref = (null)
|
Indicates the information fields provided by Layer 3. The information is sent one frame at a time. If multiple frames need to be sent, several Information commands are sent. The pd value is the protocol discriminator. The value 8 indicates it is call control information. The call reference number is always null for SPID information.
|
SPID information i = 0x343135393033383336363031
|
Indicates the SPID. The local router sends this information to the ISDN switch to indicate the services to which it subscribes. SPIDs are assigned by the service provider and are usually 10-digit telephone numbers followed by optional numbers. Currently, only the DMS-100 switch supports SPIDs, one for each B channel. If SPID information is sent to a switch type other than DMS-100, an error may be displayed in the debug information.
|
ns = 0
|
Indicates the send sequence number of sent I frames.
|
nr = 0
|
Indicates the expected send sequence number of the next received I frame. At time of transmission, this value should be equal to the value of ns. The value of nr is used to determine whether frames need to be re-sent for recovery.
|
RRr
|
Indicates the Receive Ready response for unacknowledged information transfer. The RRr is a response to an INFOc.
|
RRp
|
Indicates the Receive Ready command with the poll bit set. The data link layer entity on the user side uses the poll bit in the frame to solicit a response from the peer on the network side.
|
RRf
|
Indicates the Receive Ready response with the final bit set. The data link layer entity on the network side uses the final bit in the frame to indicate a response to the poll.
|
sapi
|
Indicates the service access point identifier. The SAPI is the point at which data link services are provided to a network layer or management entity. Currently, this field can have the value 0 (for call control procedure) or 63 (for Layer 2 management procedures).
|
tei
|
Indicates the terminal endpoint identifier (TEI) that has been assigned automatically by the assignment source point (ASP) (also called the layer management entity on the network side). The valid range is from 64 to 126. The value 127 indicates a broadcast.

Usage Guidelines
The ISDN network layer interface provided by the router conforms to the user interface specification defined by ITU-T recommendation Q.931, supplemented by other specifications such as for switch type VN4. The router tracks only activities that occur on the user side, not the network side, of the network connection. The display information debug isdn q931 command output is limited to commands and responses exchanged during peer-to-peer communication carried over the D channel. This debug information does not include data sent over the B channels, which are also part of the router's ISDN interface. The peers (network layers) communicate with each other via an ISDN switch over the D channel.
A router can be the calling or the called party of the ISDN Q.931 network connection call setup and teardown procedures. If the router is the calling party, the command displays information about an outgoing call. If the router is the called party, the command displays information about an incoming call.
This command decodes parameters of the Facility IE and displays them as text, along with parameter values as they are applicable and as they are relevant to the operation. In addition, the ASN.1 encoded Notification structure of the Notification-Indicator IE is also decoded.
You can use the debug isdn q931 command with the debug isdn event and the debug isdn q921 commands at the same time. The displays will be intermingled. Use the service timestamps debug datetime msec global configuration command to include the time with each message.
Examples
The following is sample output from the debug isdn q931 command of a call setup procedure for an outgoing call:
TX -> SETUP pd = 8 callref = 0x04
Bearer Capability i = 0x8890
Called Party Number i = 0x80, `415555121202'
RX <- CALL_PROC pd = 8 callref = 0x84
RX <- CONNECT pd = 8 callref = 0x84
TX -> CONNECT_ACK pd = 8 callref = 0x04....
Success rate is 0 percent (0/5)
The following is sample output from the debug isdn q931 command of a call setup procedure for an incoming call:
RX <- SETUP pd = 8 callref = 0x06
Bearer Capability i = 0x8890
Calling Party Number i = 0x0083, `81012345678902'
TX -> CONNECT pd = 8 callref = 0x86
RX <- CONNECT_ACK pd = 8 callref = 0x06
The following is sample output from the debug isdn q931 command that shows the contents of the Facility IE. The following example uses the supplementary service Malicious Call Identification (MCID). In this service, the router sends out the Facility IE.
Sep 20 04:09:38.335 UTC: ISDN Se7/1:23 Q931: TX -> DISCONNECT pd = 8 callref = 0x0007

Table 202 describes the significant fields shown in the displays, in alphabetical order.
Table 202 debug isdn q931 Field Descriptions
Field
|
Description
|
Bearer Capability
|
Indicates the requested bearer service to be provided by the network.
|
CALL_PROC
|
Indicates the CALL PROCEEDING message; the requested call setup has begun and no more call setup information will be accepted.
|
Called Party Number
|
Identifies the called party. This field is present only in outgoing SETUP messages. Note that it can be replaced by the Keypad facility field. This field uses the IA5 character set.
|
Calling Party Number
|
Identifies the origin of the call. This field is present only in incoming SETUP messages. This field uses the IA5 character set.
|
callref
|
Indicates the call reference number in hexadecimal notation. The value of this field indicates the number of calls made from either the router (outgoing calls) or the network (incoming calls). Note that the originator of the SETUP message sets the high-order bit of the call reference number to 0. The destination of the connection sets the high-order bit to 1 in subsequent call control messages, such as the CONNECT message. For example, callref = 0x04 in the request becomes callref = 0x84 in the response.
|
Cause
|
Indicates the cause of the disconnect.
|
Channel ID
|
Indicates the channel identifier. The value 83 indicates any channel, 89 indicates the B1 channel, and 8A indicates the B2 channel. For more information about the channel identifier, refer to ITU-T Recommendation Q.931.
|
Codeset 6 IE 0x1 i = 0x82, `10'
|
Indicates charging information. This information is specific to the NTT switch type and may not be sent by other switch types.
|
CONNECT
|
Indicates that the called user has accepted the call.
|
CONNECT_ACK
|
Indicates that the calling user acknowledges the called user's acceptance of the call.

i =
|
Indicates the information element identifier. The value depends on the field it is associated with. Refer to the ITU-T Q.931 specification for details about the possible values associated with each field for which this identifier is relevant.
|
Looking Shift to Codeset 6
|
Indicates that the next information elements will be interpreted according to information element identifiers assigned in codeset 6. Codeset 6 means that the information elements are specific to the local network.
|
pd
|
Indicates the protocol discriminator. The protocol discriminator distinguishes messages for call control over the user-network ISDN interface from other ITU-T-defined messages, including other Q.931 messages. The protocol discriminator is 8 for call control messages such as SETUP. For basic-1tr6, the protocol discriminator is 65.
|
Protocol Profile
|
Remote operations protocol, which contains networking extensions for other services. This profile determines which protocol should be used to decode the rest of a Facility IE message.
A Facility IE can contain multiple components. Each component displays a hexadecimal code followed by the code contents in text. In the example that included encoded ISDN Facility IE message output, 0xA106020107020103 is the hexadecimal code and represents the Facility IE Component, Invoke Id, and Operation. The Operation portion of the IE corresponds to the supplementary service that the component represents.

Usage Guidelines
Use the debug isis rib command to verify if an IP prefix has been installed or removed. To monitor updates from the IS-IS database to the IS-IS local RIB, use the local keyword, and to monitor updates from the IS-IS database to the global RIB, use the global keyword.
It is highly recommended that you limit the debugging output to information specific to the IP prefix that is associated with a specific access list by entering the accest-list-number argument.
Examples
The following is sample output from the debug isis rib command after the ip route priority high command was used to give high priority to IS-IS IP prefixes for the configured access list access-list1. The debug output shows that the route 10.1.1.0/24 has been removed from the IS-IS local RIB.

debug isis spf statistics
To display statistical information about building routes between intermediate systems (ISs), use the debug isis spf statistics command in privileged EXEC mode. To disable debugging output, use the no form of this command.
debug isis spf statistics
no debug isis spf statistics
Syntax Description
This command has no arguments or keywords.
Command Modes
Privileged EXEC
Usage Guidelines
The Intermediate System-to-Intermediate System (IS-IS) Interdomain Routing Protocol (IDRP) provides routing between ISs by flooding the network with link-state information. IS-IS provides routing at two levels, intra-area (Level 1) and intra-domain (Level 2). Level 1 routing allows Level 1 ISs to communicate with other Level 1 ISs in the same area. Level 2 routing allows Level 2 ISs to build an interdomain backbone between Level 1 areas by traversing only Level 2 ISs. Level 1 ISs only need to know the path to the nearest Level 2 IS in order to take advantage of the interdomain backbone created by the Level 2 ISs.
The IS-IS protocol uses the shortest-path first (SPF) routing algorithm to build Level 1 and Level 2 routes. The debug isis spf statistics command provides information for determining the time required to place a Level 1 IS or Level 2 IS on the shortest path tree (SPT) using the IS-IS protocol.
Note
The SPF algorithm is also called the Dijkstra algorithm, after the creator of the algorithm.
Examples
The following is sample output from the debug isis spf statistics command:
Router# debug isis spf statistics
ISIS-Stats: Compute L1 SPT, Timestamp 2780.328 seconds
ISIS-Stats: Complete L1 SPT, Compute time 0.004, 1 nodes on SPT
ISIS-Stats: Compute L2 SPT, Timestamp 2780.3336 seconds
ISIS-Stats: Complete L2 SPT, Compute time 0.056, 12 nodes on SPT
Table 206 describes the significant fields shown in the display.

The following is sample output from the debug kerberos command for a login attempt that was successful. The information indicates that the router sent a request to the key distribution center (KDC) and received a valid credential.
Kerberos: Requesting TGT with expiration date of 820911631
Kerberos: Sent TGT request to KDC
Kerberos: Received TGT reply from KDC
Kerberos: Received valid credential with endtime of 820911631
The following is sample output from the debug kerberos command for a login attempt that failed. The information indicates that the router sent a request to the KDC and received a reply, but the reply did not contain a valid credential.
Kerberos: Requesting TGT with expiration date of 820911731
Kerberos: Sent TGT request to KDC
Kerberos: Received TGT reply from KDC
Kerberos: Received invalid credential.
AAA/AUTHEN (425003829): password incorrect
The following output shows other failure messages you might see that indicate a configuration problem. The first message indicates that the router failed to find the default Kerberos realm, therefore the process failed to build a message to send to the KDC. The second message indicates that the router failed to retrieve its own IP address. The third message indicates that the router failed to retrieve the current time. The fourth message indicates the router failed to find or create a credentials cache for a user, which is usually caused by low memory availability.
Kerberos: authentication failed when parsing name
Kerberos: authentication failed while getting my address

Usage Guidelines
For incoming dial peers if you configure multiple DTMF negotiation methods, the first configure value takes precedence, then the second, then the third.
For incoming dial peers, the first out-of-band negotiation method takes precedence over other DTMF negotiation methods, except when rtp-nte has precedence; in this case, sip-kpml takes precedence over other out-of-band negotiation methods.
For incoming dial peers, if both sip-kpml and rtp-nte notification mechanisms are enabled and negotiated, the gateway relies on RFC 2833 notification to receive digits and a SUBSCRIBE for KPML is not initiated.
SIP KPML support complies to the IEFT draft "draft-ietf-sipping-kpml-04.txt" with the following limitations:
•
The SIP gateway always initiates SUBSCRIBE in the context of an established INVITE dialog. The gateway supports receiving SUBSCRIBE in the context of an established INVITE dialog, as well as out-of-call context requests with a leg parameter in the Event header. If the request code does not match an existing INVITE dialog, the gateway sends a NOTIFY with KPML status-code 481 and sets Subscription-State to terminated.
•
The gateway does not support the Globally Routable User Agent (GRUU) requirement. The Contact header in the INVITE/200 OK message generates locally from the gateway's contact information.
•
The gateway always initiates persistent subscriptions, but it receives and processes persistent and one-shot subscriptions.
•
The gateway supports only single-digit reporting. There is no need for inter-digit timer support. The only regular expressions supported are those which match to a single digit. For example:
–
<regex>x</regex>—Matches to any digit 0 through 9
–
<regex>1</regex>—Matches digit 1
–
<regex>[x#*ABCD]</regex>—Matches to any digit 0 through 9, # (the pound sign), * (an asterisk), or A, B, C, or D
–
<regex>[24]</regex>—Matches digits 2 or 4
–
<regex>[2-9]</regex>—Matches on any digit 2 through 9
–
<regex>[^2-9]</regex>—Matches digits 0 or 1
•
The gateway does not support long key presses. Long key presses are detected and reported as a single digit press.
•
Digit suppression is not supported (pre tag for suppressing inband digits).
•
Individual stream selection is not supported. A SUBSCRIBE request for KPML applies to all audio streams in the dialog (stream element and reverse not supported).
You can configure support only on a SIP VoIP dial peer.

The SGSN module uses the proprietary Layer 2 Relay protocol in conjunction with the intra-Serving GPRS Support Node (iSGSN) protocol for communication between the SGSN-datacom (SGSN-D) and SGSN-telecom (SGSN-T) units that comprise the SGSN.
For debugging purposes, it might also be useful to trace Layer 2 Relay packets. To display information about Layer 2 Relay packets, use the debug l2relay packets command.
Normally you will not need to use the debug l2relay events or debug l2relay packets commands. If problems with the SGSN are encountered, Cisco technical support personnel may request that issue the command.
Caution 
Because the
debug l2relay events command generates a substantial amount of output, use it only when traffic on the GPRS network is low, so other activity on the system is not adversely affected.
Examples
The following example enables the display of Layer 2 Relay events:
Router# debug l2relay events

debug lane signaling
To display information about LANE Server (LES) and Broadcast and Unknown Server (BUS) switched virtual circuits (SVCs), use the debug lane signaling command in privileged EXEC mode. To disable debugging output, use the no form of this command.
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 debugging messages.
|
Command Modes
Privileged EXEC
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.
Examples
The following is sample output from the debug lane signaling command when an interface with LECS, LES/BUS, and LEC is shut down:

debug lapb
To display all traffic for interfaces using Link Access Procedure, Balanced (LAPB) encapsulation, use the debug lapb command in privileged EXEC mode. To disable debugging output, use the no form of this command.
debug lapb
no debug lapb
Syntax Description
This command has no arguments or keywords.

11.0
|
This command was introduced prior to this release.
|
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.
The debug lapb command can generate debugging messages of LAPB on all interfaces configured with the encapsulation lapb command or when X.25 traffic is present on interfaces configured with the encapsulation x25 command. LAPB debugging produces a substantial amount of data and makes debugging very tedious. The problem becomes more severe if the network contains a large number of X.25 interfaces. Therefore the LAPB debugs are set to be available for individual interface.
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):
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 208 describes the first seven fields.
Table 208 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 present only 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 data terminal equipment (DTE)/data communications equipment (DCE) assignments are not correct for this link.
• BAD-ADDR—Address field is neither Command nor Response
|
A timer event displays only the first six fields of debug lapb command output. For frame events, however, the seventh field documents the LAPB control information present in the frame. Depending on the value of the frame type name shown in the sixth field, the seventh field may or may not appear.
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 also be highlighted, 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 tha 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
The output in the next example shows that the debug lapb command is set for a single interface; that is, interface 0/0.
Serial0/0: LAPB O CONNECT (17) IFRAME 1 7
Serial0/0: LAPB I CONNECT (5) IFRAME 7 2
Serial0/0: LAPB I CONNECT (6) IFRAME 0 2
Serial0/0: LAPB O CONNECT (2) RR (R) 1
Serial0/0: LAPB O CONNECT (50) IFRAME 2 1
Serial0/0: LAPB I CONNECT (15) IFRAME 1 2
Serial0/0: LAPB O CONNECT (5) IFRAME 3 2

debug lex rcmd
no debug lex rcmd
Syntax Description
This command has no arguments or keywords.
Command Modes
Privileged EXEC
Examples
The following is sample output from the debug lex rcmd command:
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: 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:
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 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 license

Syntax Description
list
|
(Optional) An access list number in the range from 1100 to 1199.
|
interface
|
(Optional) The interface 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
|
Command Modes
Privileged EXEC
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 arp
•
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 Logical Link Control, type 2 (LLC2) connections, use the show llc2 command to display the active connections:
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 llc2 packet
LLC2 Packets debugging is on
To use the debug list command for Synchronous Data Link Control (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:
SDLC link debugging is on
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
SDLC link debugging is on
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:
Token Ring Interface debugging is on
To enable routing information field (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:
RIF update debugging is on
