Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
EFD can only be enabled for down MEPs within a down MEPs service.
If the efd command is issued when any MEP in the service has any of the following error conditions, the MEP
will shut down the interface:
• The MEP appears cross-connected to another MAID.
• The MEP is receiving invalid CCMs, such as receiving its own MAC or MEP-ID.
• All peer MEPs are reporting a state other than UP via the Port Status TLV.
• A peer MEP is reporting a state other than UP in Interface Status TLV.
Enables protection switching, which causes high-priority notifications to be sent when
peer MEPs specified for cross-check time out, or when CCMs are received with the
RDI bit set.
Note
The high-priority notifications only apply to MEPs that are offloaded. In the
case of non-offloaded MEPs, enabling protection switching has no effect,
and the command only enables EFD.
