3-28 ENABLE SWITCH DEBUG AR400 Series Router Software Reference

Software Release 2.6.6

C613-03079-00 REV A

ENABLE SWITCH DEBUG

Syntax ENABLE SWITCH DEBUG={ARL|DMA|M6|PHY|ALL} [OUTPUT=CONSOLE]

[TIMEOUT={1..4000000000|NONE}]

Description This command enables the specified switch debug mode or all switch

debugging.

Enabling debug may flood the receiving Telnet session or asynchronous port

with raw data.

The DEBUG parameter specifies the switch debug mode to be disabled (see

Table 3-9 on page 3-28). If ALL is specified, all switch debugging modes are

enabled.

The OUTPUT parameter set to CONSOLE specifies that the debugging

information produced is sent to the console. The debugging data is by default

sent to the port where it received the ENABLE SWITCH DEBUG command.

Use this option if the command is in a script since a script is not received on a

port.

The TIMEOUT parameter specifies the time in seconds for which any switch

debugging is enabled. This reduces the risk of overloading the router and the

display with too much debugging information. The value set by the TIMEOUT

parameter overrides any previous switch debugging timeout values, even if

they were specified for other debugging modes. If TIMEOUT is not specified,

the time out is the most recent one from a previous ENABLE VLAN DEBUG

command or NONE if it had not been set.

Example To enable the ARL switch debugging mode, use the command:

ENABLE SWITCH DEBUG=ARL
