Usage
Information
Ensure to enable SyncE on the interfaces for ESMC to work on the interfaces. When ESMC capability
is disabled, it indicates that the interface is not going to receive or transmit QL. In that case, QL of
the interface can be configured using the sync-e quality-level command. The no form of this
command removes the configuration.
Example
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# sync-e esmc rx

Incoming ESMC messages with extended QL TLV are processed regardless of whether extended QL TLV
configuration is disabled or not. The no version of this command reenables QL TLV support for the ESMC
transmit messages.
