debug source event
To display information on source-route bridging activity, use the debug source event command in privileged EXEC mode. To disable debugging output, use the no form of this command.
debug source event
no debug source event
Syntax Description
This command has no arguments or keywords.
Command Modes
Privileged EXEC
Usage Guidelines
Some of the output from the debug source bridge and debug source error commands is identical to the output of this command.
Note
In order to use the debug source event command to display traffic source-routed through an interface, you first must disable fast switching of SRB frames with the no source bridge route-cache interface configuration command.
Examples
The following is sample output from the debug source event command:
Router# debug source event
RSRB0: forward (srn 5 bn 1 trn 10), src: 8110.2222.33c1 dst: 1000.5a59.04f9
RSRB0: forward (srn 5 bn 1 trn 10), src: 8110.2222.33c1 dst: 1000.5a59.04f9
RSRB0: forward (srn 5 bn 1 trn 10), src: 8110.2222.33c1 dst: 1000.5a59.04f9
RSRB0: forward (srn 5 bn 1 trn 10), src: 8110.2222.33c1 dst: 1000.5a59.04f9
RSRB0: forward (srn 5 bn 1 trn 10), src: 8110.2222.33c1 dst: 1000.5a59.04f9
Table 230 describes the significant fields shown in the display.

Description
|
RSRB0:
|
Indication that this RIF cache entry is for the Token Ring interface 0, which has been configured for remote source-route bridging (SRB). (SRB1, in contrast, would indicate that this RIF cache entry is for Token Ring 1, configured for SRB.)
|
forward
|
Forward (normal data) packet, in contrast to a control packet containing proprietary Cisco bridging information.
|
srn 5
|
Ring number of the source ring of the packet.
|
bn 1
|
Bridge number of the bridge this packet traverses.
|
trn 10
|
Ring number of the target ring of the packet.
|
src: 8110.2222.33c1
|
Source address of the route in this RIF cache entry.
|
dst: 1000.5a59.04f9
|
Destination address of the route in this RIF cache entry.
|
[0800.3201.00A1.0050]
|

In the following example messages, SRBnumber or RSRBnumber denotes a message associated with interface Token Ring number. A number of 99 denotes the remote side of the network.
SRBnumber: no path, s: source-MAC-addr d: dst-MAC-addr rif: rif
In the preceding example, a bridgeable packet came in on interface Token Ring number but there was nowhere to send it. This is most likely a configuration error. For example, an interface has source bridging turned on, but it is not connected to another source bridging interface or a ring group.
In the following example, a bridgeable packet has been forwarded from Token Ring number to the target ring. The two interfaces are directly linked.
SRBnumber: direct forward (srn ring bn bridge trn ring)
In the following examples, a proxy explorer reply was not generated because the address could not be reached from this interface. The packet came from the node with the first address.
SRBnumber: br dropped proxy XID, address for address, wrong vring (rem)
SRBnumber: br dropped proxy TEST, address for address, wrong vring (rem)
SRBnumber: br dropped proxy XID, address for address, wrong vring (local)
SRBnumber: br dropped proxy TEST, address for address, wrong vring (local)
SRBnumber: br dropped proxy XID, address for address, no path
SRBnumber: br dropped proxy TEST, address for address, no path
In the following example, an appropriate proxy explorer reply was generated on behalf of the second address. It is sent to the first address.
SRBnumber: br sent proxy XID, address for address[rif]
SRBnumber: br sent proxy TEST, address for address[rif]
The following example indicates that the broadcast bits were not set, or that the routing information indicator on the packet was not set:
SRBnumber: illegal explorer, s: source-MAC-addr d: dst-MAC-addr rif: rif
The following example indicates that the direction bit in the RIF field was set, or that an odd packet length was encountered. Such packets are dropped.
SRBnumber: bad explorer control, D set or odd
The following example indicates that a spanning explorer was dropped because the spanning option was not configured on the interface:
SRBnumber: span dropped, input off, s: source-MAC-addr d: dst-MAC-addr rif: rif
The following example indicates that a spanning explorer was dropped because it had traversed the ring previously:
SRBnumber: span violation, s: source-MAC-addr d: dst-MAC-addr rif: rif
The following example indicates that an explorer was dropped because the maximum hop count limit was reached on that interface:
SRBnumber: max hops reached - hop-cnt, s: source-MAC-addr d: dst-MAC-addr rif: rif
The following example indicates that the ring exchange request was sent to the indicated peer. This request tells the remote side which rings this node has and asks for a reply indicating which rings that side has.
RSRB: sent RingXreq to ring-group/ip-addr
The following example indicates that a message was sent to the remote peer. The label variable can be AHDR (active header), PHDR (passive header), HDR (normal header), or DATA (data exchange), and op can be Forward, Explorer, Ring Xchg, Req, Ring Xchg, Rep, Unknown Ring Group, Unknown Peer, or Unknown Target Ring.
RSRB: label: sent op to ring-group/ip-addr
The following example indicates that the remote bridge and ring pair were removed from or added to the local ring group table because the remote peer changed:
RSRB: removing bn bridge rn ring from ring-group/ip-addr
RSRB: added bridge bridge, ring ring for ring-group/ip-addr
The following example shows miscellaneous remote peer connection establishment messages:
RSRB: peer ring-group/ip-addr closed [last state n]
RSRB: passive open ip-addr(remote port) -> local port
RSRB: CONN: opening peer ring-group/ip-addr, attempt n
RSRB: CONN: Remote closed ring-group/ip-addr on open
RSRB: CONN: peer ring-group/ip-addr open failed, reason[code]
The following example shows that an explorer packet was propagated onto the local ring from the remote ring group:
RSRBn: sent local explorer, bridge bridge trn ring, [rif]
The following messages indicate that the RSRB code found that the packet was in error:
RSRBn: ring group ring-group not found
RSRBn: explorer rif [rif] not long enough
The following example indicates that a buffer could not be obtained for a ring exchange packet (this is an internal error):
RSRB: couldn't get pak for ringXchg
The following example indicates that a ring exchange packet was received that had an incorrect length (this is an internal error):
RSRB: XCHG: req/reply badly formed, length pak-length, peer peer-id
The following example indicates that a ring entry was removed for the peer; the ring was possibly disconnected from the network, causing the remote router to send an update to all its peers.
RSRB: removing bridge bridge ring ring from peer-id ring-type
The following example indicates that a ring entry was added for the specified peer; the ring was possibly added to the network, causing the other router to send an update to all its peers.
RSRB: added bridge bridge, ring ring for peer-id
The following example indicates that no memory was available to add a ring number to the ring group specified (this is an internal error):
RSRB: no memory for ring element ring-group
The following example indicates that memory was corrupted for a connection block (this is an internal error):
RSRB: CONN: corrupt connection block
The following example indicates that a connector process started, but that there was no packet to process (this is an internal error):
RSRB: CONN: warning, no initial packet, peer: ip-addr peer-pointer
The following example indicates that a packet was received with a version number different from the one pre-sent on the router:
RSRB: IF New version. local=local-version, remote=remote-version,pak-op-code peer-id
The following example indicates that a packet with a bad op code was received for a direct encapsulation peer (this is an internal error):
RSRB: IFin: bad op op-code (op code string) from peer-id
The following example indicates that the virtual ring header will not fit on the packet to be sent to the peer (this is an internal error):
RSRB: vrif_sender, hdr won't fit
The following example indicates that the specified peer is being opened. The retry count specifies the number of times the opening operation is attempted.
RSRB: CONN: opening peer peer-id retry-count
The following example indicates that the router, configured for FST encapsulation, received a version reply to the version request packet it had sent previously:
RSRB: FST Rcvd version reply from peer-id (version version-number)
The following example indicates that the router, configured for FST encapsulation, sent a version request packet to the specified peer:
RSRB: FST Version Request. op = opcode, peer-id
The following example indicates that the router received a packet with a bad op code from the specified peer (this is an internal error):
RSRB: FSTin: bad op opcode (op code string) from peer-id
The following example indicates that the TCP connection between the router and the specified peer is being aborted:
RSRB: aborting ring-group/peer-id (vrtcpd_abort called)
The following example indicates that an attempt to establish a TCP connection to a remote peer timed out:
RSRB: CONN: attempt timed out
The following example indicates that a packet was dropped because the ring group number in the packet did not correlate with the ring groups configured on the router:
RSRBnumber: ring group ring-group not found

This command was introduced on the Cisco AS5350 and Cisco AS5400 Signaling Link Terminal (SLT).
|
Usage Guidelines
The following debug commands are not used in this release:
•
debug ss7 mtp1 rx
•
debug ss7 mtp1 tx
•
debug ss7 mtp1 scc-regs
•
debug ss7 mtp1 siram
Examples
To turn on message tracing between the host processor and the trunk firmware for each trunk card inserted, use the debug ss7 mtp1 ipc command.
For example, there is a digital link in slot 7, trunk 0, channel-group 0 (therefore, timeslot 1). When you enter show ss7 mtp1 links, the following output is displayed:
Router# show ss7 mtp1 links
SS7 MTP1 Links [num = 1, platform max = 4]:
interface type SCC state channel
--------- -------- --- ------------ -------
7/0:0 digital 7/3 STOPPED 0
Notice that the link is stopped in this example. Enter the following commands:
Router# debug ss7 mtp1 ipc
Router# configure terminal
Router(config)# interface serial 7/0:0
Router(config-if)# no shutdown
You would see trace output similar to the following:
00:01:27:from Trunk(7):TRUNK_SERIAL_STOP(3), link_type=2
00:01:27:from Trunk(7):TRUNK_SERIAL_START(3), link_type=2
In this case, the output means that for the SS7 link that is using SCC3 on the trunk card in slot 7 (link 7/0:0), the host processor has told the board firmware to STOP then START.
To show low-level (MTP1) state changes for the internal state-machine implemented for each SS7 link, use the debug ss7 mtp1 link-state command. The following output shows the different MTP1 states link Serial 7/0:0 goes through during shutdown, no shutdown, and debug.
For example, if you stopped the SS7 link 7/0:0 (shutdown), then restarted it (no shutdown), you could see MTP1 state changes by enabling debugging, as follows:
Router# debug ss7 mtp1 link-state
Router# configure terminal
Router(config)# interface serial 7/0:0
Router(config-if)# shutdown
01:02:20:%TRUNK_SERIAL-3-STATE_GENERIC:

At ../src-7k-as5400/as5400_ss7_link.c:1010 [Serial7/0:0]: FW_STOPPED:
Now restart the link:
Router(config-if)# no shutdown
01:02:26:ss7_link_start:slot=7/SCCport=3 current state is STOPPED
01:02:26:%TRUNK_SERIAL-3-STATE_GENERIC:

At ../src-7k-as5400/as5400_ss7_link.c:1234 [Serial7/0:0]: FW_STARTED:
To show detailed information about how TDM timeslots on the DFC trunk card on the host backplane are allocated and deallocated based on link configuration activity, use the debug ss7 mtp1 tdm-info command.
For example, if you wanted to create a digital SS7 link on timeslot 1 of trunk 0 for an 8PRI board in slot 7, and you would like to see traces of the TDM resources allocated, you would enable TDM debugging using the debug ss7 mtp1 tdm-info command then create the new SS7 link as described above, as in the following example:
Router# debug ss7 mtp1 tdm-info
Router# configure terminal
Router(config)# controller t1 7/0
Router(config-controller)# channel-group 0 timeslots 1
Router(config-controller)# exit
Router(config)# interface serial 7/0:0
Router(config-if)# encapsulation ss7
Due to the debug flag, the following information is displayed:
05:26:55: ss7_link_flink_tdm_setup:card type for slot 7 is T1 8PRI
05:26:55: ds0-side BEFORE call to tdm_allocate_bp_ts()
05:26:55: scc-side BEFORE call to tdm_allocate_bp_ts()
05:26:55:TDM(PRI:0x28002000):Close PRI framer st0 ch4
05:26:55:<<< tdm_allocate_bp_ts(ss7_ch) SUCCEEDED >>>
05:26:55:scc-side AFTER call to tdm_allocate_bp_ts()
bp_ts->vdev_slot = 7 should be same as the CLI slot, and bp_ts->vdev_channel = 3should be *->channel.
When you later remove the SS7 link, other information is displayed showing how resources are cleaned up.

|
12.0(7)XR and 12.1(1)T
|
This command was introduced.
|
12.1(1)T
|
This command was integrated into Cisco IOS Release 12.1(1)T.
|
12.2(11)T
|
This command replaces the debug ss7 sm session command. This command was modified with the session, set, and timer keywords. This command was also modified to support up to four Session Manager sessions.
|
Usage Guidelines
Use this command to watch the Session Manager and Reliable User Data Protocol (RUDP) sessions. The Session Manager is responsible for establishing the RUDP connectivity to the Virtual Switch Controller (VSC).
Support for up to four Session Manager sessions was added. Session Manager sessions are now numbered 0 through 3. This feature changes the CLI syntax, and adds sessions 2 and 3.
Examples
The following is an example of debug ss7 sm command output using the session keyword. The Session Manager has established the connection (RUDP_CONN_OPEN_SIG) for session 3.
Router# debug ss7 sm session 3
*Mar 8 09:37:52.119:SM:rudp signal RUDP_SOFT_RESET_SIG, session = 3

*Mar 8 09:37:58.137:SM:rudp signal RUDP_CONN_OPEN_SIG, session = 3
The following is an example of debug ss7 sm session command output for session 0. The Session Manager has established the connection (RUDP_CONN_OPEN_SIG):
Router# debug ss7 sm session 0
*Mar 8 09:37:52.119:SM:rudp signal RUDP_SOFT_RESET_SIG, session = 0

Usage Guidelines
Use this command to turn on debug information for the SSG TCP Redirect for Services feature. Use the packet keyword to display redirection information and any changes made to a packet when it is due for redirection. Use the error keyword to display any SSG TCP redirect errors. Use the event keyword to display any major SSG TCP redirect events or state changes.
Note
This command replaces the debug ssg packets command.
Examples
The following example shows how to display redirection information and any changes made to a packet when it is due for redirection:
Router# debug ssg tcp-redirect packet
Direction of the packet "-Up" indicates upstream packets from an SSG user, while "-Down" indicates downstream packets sent to a user:
07:13:15:SSG-REDIR-PKT:-Up:unauthorised user at 111.0.0.2 redirected to 9.2.36.253,8080
07:13:15:SSG-REDIR-PKT:-Down:TCP-RST Rxd for user at 111.0.0.2, port 11114
07:13:15:SSG-REDIR-PKT:-Down:return remap for user at 111.0.0.2 redirected from 9.2.36.25
The following example shows how to display any SSG TCP redirect errors:
Router# debug ssg tcp-redirect error
07:15:20:SSG-REDIR-ERR:-Up:Packet from 172.0.0.2:11114 has different destination from
stored connection
The following example shows how to display any major SSG TCP redirect events or state changes:

debug syslog-server
To display information about the syslog server process, use the debug syslog-server command in privileged EXEC mode. To disable debugging output, use the no form of this command.
debug syslog-server
no debug syslog-server
Syntax Description
This command has no arguments or keywords.
Command Modes
Privileged EXEC
Usage Guidelines
This command outputs a message every time the syslog server receives a message. It also displays information about subfile creation, removal, and renaming.
Use this command when subfiles are not being created as configured or data is not being written to subfiles. This command is also useful for detecting syslog file size mismatches.
Examples
The following sample display shows output when the following command has been added to the configuration:
logging syslog-server 10 3 syslogs
This example shows the files being created. Use the dir disk0:/syslogs.dir command to display the contents of the newly created directory.
Router# debug syslog-server
SYSLOG_SERVER:Syslog file syslogs
SYSLOG_SERVER:Directory disk0:/syslogs.dir created.
SYSLOG_SERVER:Syslog file syslogs created successfully.
When a syslog message is received, the router checks to determine if the current file will be too large when the new data is added. In this example, two messages are added to the file.
SYSLOG_SERVER: Configured size : 10240 bytes
SYSLOG_SERVER: Wrote 68 bytes successfully.
SYSLOG_SERVER: Configured size : 10240 bytes
SYSLOG_SERVER: Wrote 61 bytes successfully.
Table 235 describes the significant fields shown in the display.
