The debug output consists of exceptional events, which should not occur during normal operations. However, these exceptions are not indicative of a software failure.
The following example enables the debugging of SGCP error events.
Switch# debug sgcp errors
Simple Gateway Control Protocol errors debugging is on
debug sgcp events
debug sgcp packets
To enable the production of debug information on significant events encountered in the use of SGCP to control the interconnection of CES circuits, use the debug sgcp events privileged EXEC command. To disable debugging, use the no form of this command.
debug sgcp eventsThis command has no arguments or keywords.

Privileged EXEC
The principle debug output includes circuit state changes that occur because of SGCP packet and CES circuit events.
The following example enables the debugging of SGCP events.
Switch# debug sgcp events

To debug the tag-switching configuration, use the debug tag-switching privileged EXEC commands. To disable tag-switching debugging, use the no form of these commands.
debug tag-switching adjacency
adjacency | Displays changes to tag switching entries in the adjacency database. Use this option to monitor instances when entries are updated or added to the adjacency database. |
atm-tdp api | Displays information about the VCI allocation of TVCs, free, and cross-connect requests. Use the debug tag-switching atm-tdp api command with the debug tag-switching atm-tdp states command to display more complete information about a TVC. |
atm-tdp routes | Displays information about the state of the routes for which VCI requests are being made. See also "Usage Guidelines." |
atm-tdp states | Displays information about TVC state transitions as they occur. See also |
packets | Displays tagged packets switched by this system. The optional if-type (atm, atm-p, cbr, ethernet, or null) and card/subcard/port arguments restrict the display to those packets received or transmitted on the specified interface type or number. This command should be used with care because it generates output for every packet processed. Furthermore, enabling this command causes fast and distributed tag switching to be disabled for the selected interfaces. Use this command only when traffic on the network is low, so other activity on the system is not adversely affected. |
tdp advertisements | Displays information about the advertisement of tags and interface addresses to TDP peers. |
tdp bindings | Displays information about changes to the TIB used to keep track of tag bindings learned from TDP peers through TDP downstream tag distribution. |
tdp directed-neighbors | Displays information about TDP directed-neighbor events. |
tdp peer | Displays information about state transitions at the tag distribution level. See also "Usage Guidelines." |
tdp pies | Displays information about TDP PIEs received from (received) or sent to (sent) TDP peers. TDP requires periodic transmission of keepalive PIEs. If you do not specify the all option, periodic keepalive PIEs are not displayed. |
tdp session | Displays TDP session information. See also "Usage Guidelines." |
tdp transport | Used with the connections keyword, this command displays information about the TCP connections used to support TDP sessions. Used with the events keyword, this command displays information about the events related to the TDP peer discovery mechanism, which is used to determine the devices with which to establish TDP sessions. Used with the timers keyword, this command displays TDP discovery and transport timer activity. See also "Usage Guidelines." |
tsp-tunnels events | Displays TSP tunnels events. |
tsp-tunnels signalling | Displays TSP tunnels signalling. |
tsp-tunnels tagging | Displays TSP tunnels tagging. |
Disabled
Privileged EXEC
When there are a large number of routes and a number of system activities (shutting down interfaces, learning new routes, and so on), the debug tag-switching atm-tdp routes and debug tag-switching atm-tdp states commands display a lot of information that may interfere with system timing.
Most commonly, this affects the normal operation of TDP. You should increase the holdtime value of the TDP by using the tag-switching tdp holdtime command.
TDP sessions are supported by data structures and state machines at three levels:
The debug tag-switching tdp transport commands provide visibility of activity at the transport level, the debug tag-switching tdp session commands at the protocol level, and the debug tag-switching tdp peer state-machine command at the tag distribution level.
To return to the EXEC mode by exiting the privileged EXEC mode, use the disable EXEC command.
disable [level]
level | You can specify up to 16 privilege levels, using numbers 0 through 15. Level 1 is normal EXEC-mode user privileges. If this argument is not specified, the privilege level defaults to |
15
EXEC
In the following example, the user is logging out from privilege level 5.
Switch# disable 5
