D Commands

The commands shown in this chapter apply to the Catalyst 8540 MSR, Catalyst 8510 MSR, and LightStream 1010 ATM switch routers. Where an entire command or certain attributes of a command have values specific to a particular switch or switch router, an exception is indicated by the following callouts:

• Catalyst 8540 MSR

• Catalyst 8510 MSR and LightStream 1010

Note   Commands that are identical to those documented in the Cisco IOS software documentation have been removed from this chapter.

debug tag-switching

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.

Syntax Description

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 "Usage Guidelines."
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.

Defaults

Disabled

Command Modes

Privileged EXEC

Command History

Release	Modification
11.3(3a)	New command

Usage Guidelines

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 might 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:

• Transport—TCP connections used to support TDP sessions are established and maintained at the transport level.

• Protocol—The protocol level implements the TDP session setup protocol, and deals with constructing and parsing TDP PDUs and PIEs.

• Tag distribution—The tag distribution level uses TDP sessions to exchange tags with TDP peers.

The debug tag-switching tdp transport commands provide visible 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.

disable

To return to the EXEC mode by exiting the privileged EXEC mode, use the disable EXEC command.

Syntax Description

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 level 15 (traditional enable privileges).
