Table 7: Opcode Values - Alcatel-Lucent 7950 SR System Management Manual

Management Access Filter Commands
If the cfm-opcode match condition is configured then a check must be made to see if the Ethertype is
either IEEE802.1ag or Y1731. If the Ethertype does not match then the packet is not CFM and no
match to the cfm-opcode is attempted.
The CFM (ieee802.1ag or Y1731) opcode can be assigned as a range with a start and an end number
or with a (less than lt, greater than gt, or equal to eq) operator.
If no range with a start and an end or operator (lt, gt, eq) followed by an opcode with the value
between 0 and 255 is defined then the command is invalid.
