cfm protocol
Function
The cfm protocol command configures the EtherType value of a CCM.
The undo cfm protocol command restores the default setting.
As defined in IEEE 802.1ag/Draft 7, the default EtherType value of a CCM is 0xBBB0.
Parameters
| Parameter | Description | Value |
|---|---|---|
| ethertype-value | Specifies the EtherType value of a CCM. | The value is an integer that ranges from 0600 to FFFF. The default value is BBB0. |
Usage Guidelines
No specific protocol type is defined in IEEE 802.1ag/Draft
7, so devices of different vendors may use different protocols to
encapsulate CCMs. To allow devices of different vendors to interwork
with each other, you must run the cfm protocol command
to configure the same protocol types on these devices. Otherwise,
these devices cannot communicate.
You must run the cfm enable command to enable CFM globally before configuring the protocol
type.
