The router on which this command is used must be equipped with one or more digital T1/E1 packet voice trunk network modules (NM-HDVs) or high-density voice (HDV) transcoding and conferencing digital signal processor (DSP) farms (NM-HDV-FARMs) to provide DSP resources.
Debugging is turned on for all DSP farm service sessions. You can debug multiple sessions simultaneously, with different levels of debugging for each.
Examples
The following is sample output from the debug sccp events command:

To display information on a serial connection failure, use the debug serial interface command in privileged EXEC mode. To disable debugging output, use the no form of this command.
debug serial interface
no debug serial interface
Syntax Description
This command has no arguments or keywords.
Command Modes
Privileged EXEC
Usage Guidelines
If the show interface serial EXEC command shows that the line and protocol are down, you can use the debug serial interface command to isolate a timing problem as the cause of a connection failure. If the keepalive values in the mineseq, yourseen, and myseen fields are not incrementing in each subsequent line of output, there is a timing or line problem at one end of the connection.
Caution
The output of the debug serial interface command can vary, depending on the type of WAN configured for an interface: Frame Relay, High-Level Data Link Control (HDL) , High-Speed Serial Interface (HSSI), SMDS, or X.25. The output also can vary depending on the type of encapsulation configured for that interface. The hardware platform also can affect debug serial interface output.
Examples
The following sections show and describe sample debug serial interface output for various configurations.
Debug Serial Interface for Frame Relay Encapsulation
The following message is displayed if the encapsulation for the interface is Frame Relay (or HDLC) and the router attempts to send a packet containing an unknown packet type:
Illegal serial link type code xxxDebug Serial Interface for HDLC
The following is sample output from the debug serial interface command for an HDLC connection when keepalives are enabled. This output shows that the remote router is not receiving all the keepalives the router is sending. When the difference in the values in the myseq and mineseen fields exceeds three, the line goes down and the interface is reset.
Table 294 describes the significant fields shown in the display.
Table 295 describes additional error messages that the debug serial interface command can generate for HDLC.
Debug Serial Interface for HSSI
On an HSSI interface, the debug serial interface command can generate the following additional error message:
HSSI0: Reset from 0xnnnnnnnThis message indicates that the HSSI hardware has been reset. The 0xnnnnnnn variable is the address of the routine requesting that the hardware be reset; this value is useful only to development engineers.
Debug Serial Interface for ISDN Basic Rate
Table 296 describes error messages that the debug serial interface command can generate for ISDN Basic Rate.
Debug Serial Interface for an MK5025 Device
Table 297 describes the additional error messages that the debug serial interface command can generate for an MK5025 device.
Debug Serial Interface for SMDS Encapsulation
When encapsulation is set to SMDS, the debug serial interface command displays SMDS packets that are sent and received, and any error messages resulting from SMDS packet transmission.
The error messages that the debug serial interface command can generate for SMDS follow.
The following message indicates that a new protocol requested SMDS to encapsulate the data for transmission. SMDS is not yet able to encapsulate the protocol.
SMDS: Error on Serial 0, encapsulation bad protocol = xThe following message indicates that SMDS was asked to encapsulate a packet, but no corresponding destination E.164 SMDS address was found in any of the static SMDS tables or in the ARP tables:
SMDS send: Error in encapsulation, no hardware address, type = xThe following message indicates that a protocol such as Connectionless Network Service (CLNS) or IP has been enabled on an SMDS interface, but the corresponding multicast addresses have not been configured. The n variable displays the link type for which encapsulation was requested.
SMDS: Send, Error in encapsulation, type=nThe following messages can occur when a corrupted packet is received on an SMDS interface. The router expected x, but received y.
SMDS: Invalid packet, Reserved NOT ZERO, x ySMDS: Invalid packet, TAG mismatch x ySMDS: Invalid packet, Bad TRAILER length x yThe following messages can indicate an invalid length for an SMDS packet:
SMDS: Invalid packet, Bad BA length xSMDS: Invalid packet, Bad header extension length xSMDS: Invalid packet, Bad header extension type xSMDS: Invalid packet, Bad header extension value xThe following messages are displayed when the debug serial interface command is enabled:
Interface Serial 0 Sending SMDS L3 packet:SMDS: dgsize:x type:0xn src:y dst:zIf the debug serial interface command is enabled, the following message can be displayed when a packet is received on an SMDS interface, but the destination SMDS address does not match any on that interface:

no debug sgbp error
Syntax Description
This command has no arguments or keywords.
Command Modes
Privileged EXEC
Command History
Usage Guidelines
Enter the debug sgbp error command to enable the display of debugging messages about routing problems between members of a stack group.
Note
Examples
One common configuration error is setting a source IP address for a stack member that does not match the locally defined IP address for the same stack member. The following debugging output shows the error message that results from this misconfiguration:
Systema# debug sgbp error%SGBP-7-DIFFERENT - systemb's addr 10.1.1.2 is different from hello's addr 10.3.4.5This error means that the source IP address of the Stack Group Bidding Protocol (SGBP) hello message received from systemb does not match the IP address configured locally for systemb (through the sgbp member command). Correct this configuration error by going to systemb and checking for multiple interfaces by which the SGBP hello can send the message.
Another common error message is:
Systema# debug sgbp error%SGBP-7-MISCONF, Possible misconfigured member routerk (10.1.1.6)This error message means that routerk is not defined locally, but is defined on another stack member. Correct this configuration error by defining routerk across all members of the stack group using the sgbp member command.
The following error message indicates that an SGBP peer is leaving the stack group:
Systema# debug sgbp error%SGBP-7-LEAVING:Member systemc leaving group stack1This error message indicates that the peer systemc is leaving the stack group. Systemc could be leaving the stack group intentionally, or a connectivity problem may exist.
The following error message indicates that an SGBP event was detected from an unknown peer:
Systema# debug sgbp error%SGBP-7-UNKNOWPEER:Event 0x10 from peer at 172.21.54.3An SGBP event came from a network host that was not recognizable as an SGBP peer. Check to see if a network media error could have corrupted the address, or if peer equipment is malfunctioning to generate corrupted packets. Depending on the network topology and firewall of your network, SGBP packets from a nonpeer host could indicate probing and attempts to breach security.

Note
Examples
The following output from the debug sgbp hellos command shows systema sending a successful Challenge Handshake Authentication Protocol (CHAP) challenge to and receiving a response from systemb. Similarly, systemb sends out a challenge and receives a response from systema.
systema# debug sgbp hellos%SGBP-7-CHALLENGE: Send Hello Challenge to systemb group stack1%SGBP-7-CHALLENGED: Hello Challenge message from member systemb (10.1.1.2)%SGBP-7-RESPONSE: Send Hello Response to systemb group stack1%SGBP-7-CHALLENGE: Send Hello Challenge to systemb group stack1%SGBP-7-RESPONDED: Hello Response message from member systemb (10.1.1.2)%SGBP-7-AUTHOK: Send Hello Authentication OK to member systemb (10.1.1.2)%SGBP-7-INFO: Addr = 10.1.1.2 Reference = 0xC347DF7%SGBP-5-ARRIVING: New peer event for member systembThis debug output is self-explanatory.
If authentication fails, you may see one of the following messages in your debug output:
%SGBP-7-AUTHFAILED - Member systemb failed authenticationThis error message means that the remote systemb password for the stack group does not match the password defined on systema. To correct this error, make sure that both systema and systemb have the same password defined using the username command.
%SGBP-7-NORESP -Fail to respond to systemb group stack1, may not have password.This error message means that systema does not have a username or password defined. To correct this error, define a common group password across all stack members using the username command.

To display source-route bridging (SRB) errors, use the debug source error command in privileged EXEC mode. To disable debugging output, use the no form of this command.
debug source error
no debug source error
Syntax Description
This command has no arguments or keywords.
Command Modes
Privileged EXEC
Usage Guidelines
The debug source error command displays some output also found in the debug source bridge output. See the debug source bridge command for other possible output.
Examples
In all of the following examples of debug source error command messages, the variable number is the Token Ring interface. For example, if the line of output starts with SRB1, the output relates to the Token Ring 1 interface. SRB indicates a source-route bridging message. RSRB indicates a remote source-route bridging message. SRTLB indicates a source-route translational bridging (SR/TLB) message.
In the following example, a packet of protocol protocol-type was dropped:
SRBnumber drop: Routed protocol protocol-typeIn the following example, an Address Resolution Protocol (ARP) packet was dropped. ARP is defined in RFC 826.
SRBnumber drop:TYPE_RFC826_ARPIn the following example, the current Cisco IOS version does not support Qualified Logical Link Control (QLLC). Reconfigure the router with an image that has the IBM feature set.
RSRB: QLLC not supported in version versionPlease reconfigure.In the following example, the packet was dropped because the outgoing interface of the router was down:
RSRB IF: outgoing interface not up, dropping packetIn the following example, the router received an out-of-sequence IP sequence number in a Fast Sequenced Transport (FST) packet. FST has no recovery for this problem like TCP encapsulation does.
RSRB FST: bad sequence number dropping.In the following example, the router was unable to locate the virtual interface:
RSRB: couldn't find virtual interfaceIn the following example, the TCP queue of the peer router is full. TCPD indicates that this is a TCP debug.
RSRB TCPD: tcp queue full for peerIn the following example, the router was unable to send data to the peer router. A result of 1 indicates that the TCP queue is full. A result of —1 indicates that the RSRB peer is closed.
RSRB TCPD: tcp send failed for peer resultIn the following example, the routing information identifier (RII) was not set in the explorer packet going forward. The packet will not support SRB, so it is dropped.
vrforward_explorer - RII not setIn the following example, a packet sent to a virtual bridge in the router did not include a routing information field (RIF) to tell the router which route to use:
RSRB: no RIF on packet sent to virtual bridgeThe following example indicates that the RIF did not contain any information or the length field was set to zero:
RSRB: RIF length of zero sent to virtual bridgeThe following message occurs when the local service access point (LSAP) is out of range. The variable lsap-out is the value, type is the type of RSRB peer, and state is the state of the RSRB peer.
VRP: rsrb_lsap_out = lsap-out, type = type, state = stateIn the following message, the router is unable to find another router with which to exchange bridge protocol data units (BPDUs). BPDUs are exchanged to set up the spanning tree and determine the forwarding path.
