debugging efm

Function

The debugging efm command enables all debugging EFM functions and outputs debugging information.

The undo debugging efm command disables all EFM debugging functions.

By default, all efm debugging functions are disabled.

Format

debugging efm { error | info | debug | warning | message | packet { all | receive | send } | state }

debugging efm { error | info | debug | warning | message | packet { all | receive | send } | state } interface { interfaceName | ifType ifNum }

undo debugging efm { error | info | debug | warning | message | packet { all | receive | send } | state }

undo debugging efm { error | info | debug | warning | message | packet { all | receive | send } | state } interface { interfaceName | ifType ifNum }

Usage Guidelines

Usage Scenario

When an EFM session fails to be negotiated, the debugging efm packet command displays the sent and received packets and checks whether packet sending and receiving are normal and whether the packet format is correct.
When the EFM fails to interwork with other components, the debugging efm message command displays the messages exchanged between the EFM and other components and checks whether message sending and receiving of the components are normal.
When an EFM session fails to be negotiated, the debugging efm state command displays changes of the state machine and checks whether stateful switchover is normal.
When the EFM component becomes abnormal, the debugging efm error command checks whether an error occurs in packet or message processing.
