slot/port: Specifies a valid slot and port number. For devices that do not support linecards, specify 0 for the slot.

Usage Guidelines

Diagnostic commands are developed and intended for specialized troubleshooting. Work closely with Extreme Networks technical support when running debug or show system internal commands and interpreting their results.

When debugging is enabled, UDLD PDUs are written to the console as they are transmitted and received on one or all ports.

Use the show debug udld command to view your current debug settings.

Use the no form of this command to turn off either all dumping of UDLD PDUs or dumping on a specific port.

Examples

To turn on debugging of transmitted packets on a specific ethernet interface:

device# debug udld packet interface ethernet 0/1 tx
