debug diag online (Catalyst 8540 MSR)

To enable online diagnostic debugging output, use the debug diag online command. To disable debugging, use the no form of the command.

debug diag online [access | oir | snake]

no debug diag online [access | oir | snake]

Syntax Description

access

The access tests ensure connectivity at a configurable interval between the primary route processor and the following:

Active switch processors
Standby switch processor, if it is present
Feature cards
Port adapters
Interface modules

Whenever the access test detects a hardware failure, the system issues an error message to the console.

If the access test detects a hardware problem with an active switch processor, the standby switch processor, if present, automatically takes over and becomes an active switch processor. The system generates an SNMP trap when the switchover occurs.

oir

Online insertion and removal (OIR) tests check the functioning of the switch fabric and interfaces on a per-port basis. The switch router performs these tests when the system boots up and when you insert a port adapter or interface module into a slot. The OIR test sends a packet to the interface loopback and expects to receive it back within a certain time period. If the packet does not reach the port within the expected time period, or the route processor receives a corrupted packet, the system issues an error message to the console, generates an SNMP trap, and brings the port to an administrative down state.

snake

The snake test establishes a connection across all the active ports in the switch router, originating and terminating at the primary route processor. The route processor establishes a connection by sending a packet to each port in turn, which then terminates at the route processor. If the packet does not reach the route processor within the expected time period, or the received packet is corrupted, further testing is performed to isolate and disable the port causing the problem.The size of the packet and frequency of the test are configurable to minimize the impact on system performance.

The snake test supports all ATM interface modules and enhanced Gigabit Ethernet interface modules. It does not support ATM port adapters, Fast Ethernet interface modules, or Gigabit Ethernet interface modules.

Defaults

Disabled.

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

Command Modes

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.
