Command

Description

debug tag atm-tdp

Debugs label-controlled ATM TDP.

debug tag packets

Debugs tag switching packets.

debug tag tdp

Debugs tag distribution protocol items and information.

debug tag-switching atm-tdp api

To display information about the VCI allocation of tag VCs (TVCs), free, and cross-connect requests, use the debug tag-switching atm-tdp api privileged EXEC command. The no form of this command disables debugging output.

debug tag-switching atm-tdp api
no debug tag-switching atm-tdp api
Syntax Description

This command has no arguments or keywords.

Usage Guidelines

You can 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.

Examples

The following is sample output from the debug tag-switching atm-tdp api command:
Router# debug tag-switching atm-tdp api
Tailend Router Free tag Req 167.50.0.0 on ATM0/0.2 VPI/VCI 1/674
 TAGATM_API: received tag free request
       interface: ATM0/0.2 dir: in vpi: 1 vci: 674

Command

Description

debug tag-switching atm-tdp states

Displays information about TVC state transitions as they occur.

debug tag-switching atm-tdp routes

To display information about the state of the routes for which VCI requests are being made, use the debug tag-switching atm-tdp routes privileged EXEC command. The no form of this command disables debugging output.

debug tag-switching atm-tdp routes
no debug tag-switching atm-tdp routes
Syntax Description

This command has no arguments or keywords.

Usage Guidelines

When there are many routes and system activities (that is, shutting down interfaces, learning of new routes, and so on), the debug tag-switching atm-tdp routes command displays a substantial amount of information that may interfere with system timing. Most commonly, this affects the normal operation of the Tag Distribution Protocol (TDP). You should increase the TDP hold-time value by using the tag-switching tdp holdtime command.

Description

debug tag-switching tdp directed-neighbors

To print information about the directed neighbor mechanism, use the debug tag-switching tdp directed-neighbors privileged EXEC command. The no form of this command disables debugging output.

debug tag-switching tdp directed-neighbors
no debug tag-switching tdp directed-neighbors
Syntax Description

This command has no arguments or keywords.

Usage Guidelines

This mechanism establishes TDP adjacencies to peer devices that are not directly adjacent, such as peer devices at either end of a tunnel.

The directed neighbor mechanism starts TDP discovery between two TSRs that are not necessarily directly adjacent. This mechanism is used, for instance, to support two-level tagging across a TSP tunnel, and to support traffic engineering metric exchange across a TSP tunnel.

The mechanism is based on an IP address, such as the IP address of the last hop of a TSP tunnel. A TSR wanting to establish a TDP adjacency to some other TSR with a given IP address is the active TSR for that directed neighbor discovery. A TSR willing to respond to that discovery is the passive TSR for that discovery.

As with TDP discovery between adjacent TSRs, it is possible to have multiple directed neighbor discovery sessions can run between two TSRs, all supporting a single TDP adjacency.

The debug messages track discovery changes, such as discovery or loss of a directed neighbor. As a detail reflected in the debug prints, discovery of a directed neighbor with IP address X is complete when a TDP adjacency comes up and the far end announces that IP address X is one of its IP addresses.

Examples

The following is sample output from the debug tag-switching tdp directed-neighbors command:
Router# debug tag-switching tdp directed-neighbors
tdp_directednbr: TDPDirAdj 10.11.10.11 received address addition notification
tdp_directednbr: TDPDirAdj 10.11.10.11 TDP peer set

Description

Command

Description

show tag-switching tdp neighbors

Displays the status of TDP sessions.

s

debug tag-switching tdp peer state-machine

To print information about state transitions at the tag distribution level, use the debug tag-switching tdp peer state-machine privileged EXEC command. The no form of this command disables debugging output.

debug tag-switching tdp peer state-machine
no debug tag-switching tdp peer state-machine
Syntax Description

This command has no arguments or keywords.

Usage Guidelines

TDP sessions are supported by data structures and state machines at three levels:

•Transport—The transport level establishes and maintains TCP connections used to support TDP sessions.

•Protocol—The protocol level implements the TDP session setup protocol, and constructs and parses TDP PDUs and PIEs.

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

The debug tag-switching tdp transport command provides visibility of activity at the transport level, the debug tag-switching tdp session command at the protocol level, and the debug tag-switching tdp peer command at the tag distribution level.

Examples

The following is sample output from the debug tag-switching tdp peer state-machine command:

debug tag-switching tdp session io [all]
no debug tag-switching tdp session io [all]
Syntax Description

all

(Optional) TDP session I/O activity, including I/O for periodic keepalives.

Usage Guidelines

TDP sessions are supported by data structures and state machines at three levels:

•Transport—The transport level establishes and maintains TCP connections used to support TDP sessions.

•Protocol—The protocol level implements the TDP session setup protocol, and constructs and parses TDP PDUs and PIEs.

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

The debug tag-switching tdp transport command provides visibility of activity at the transport level, the debug tag-switching tdp session command at the protocol level, and the debug tag-switching tdp peer command at the tag distribution level.

TDP requires periodic transmission of keepalive PIEs. If you do not specify the all option, periodic keepalive PIEs are not displayed.

Syntax Description

This command has no arguments or keywords.

Usage Guidelines

TDP sessions are supported by data structures and state machines at three levels:

•Transport—The transport level establishes and maintains TCP connections used to support TDP sessions.

•Protocol—The protocol level implements the TDP session setup protocol, and constructs and parses TDP PDUs and PIEs.

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

The debug tag-switching tdp transport command provides visibility of activity at the transport level, the debug tag-switching tdp session command at the protocol level, and the debug tag-switching tdp peer command at the tag distribution level.

When two devices establish a TCP connection for a TDP session, the device with the larger transport address plays an active role and the other plays a passive role. The active device attempts to establish a TCP connection to the well-known TDP port at the passive device. The passive device waits for the connection to the well-known port to be established.
