### Description

```asn1
opticsIMEthConfExtCsfMAUAction OBJECT-TYPE 
SYNTAX INTEGER 
MAX-ACCESS read-write 
STATUS current 
DESCRIPTION 
"This object identifies the consequent action triggered on local Interface 
egress port for port-to-port application in front of received CSF Frame 
indications (due to detected remote Ethernet PHY Interface failures). 
The choice of enabled CSF consequent actions is allowed to be different 
from SSF consequent actions (consequent actions coping with SDH network 
failures). 
disabled (0) is defined to perform no consequent actions. 
transmitter\_shutdown (1) is defined to trigger forced transmitter 
shut-down action. 
If the interface is not involved in a port-to-port application, this 
consequent action will never be triggered. The default value is disabled"
