Description
000 = Reserved (Do Not Use)
001 = 32µs (default)
010 = 128µs
011 = 256µs
100 = 512µs
101 = 1ms
110 = 2ms
111 = 4ms
To send a maintenance frame, an external controller writes to
these command bits via the SMI, SPI, or I
0 0000 : No request
0 0001 : Send “Condition Inform Request” frame
0 0010 : Send “Loop Mode Start Request” frame
0 0100 : Send “Loop Mode Stop Request” frame
0 1000 : Send “Remote Command”. Here, the Maintenance
frame will be made up of the “Condition Inform Request/Reply”
frame, but the My Model Info bits MM24-MM47 will be mapped
to Registers 4Ah-4Ch, instead of Registers 55h-57h.
1 0000 : Send “Indicate Center/Terminal MC Condition”
frame. Usually, “Indicate Center/Terminal MC Condition” frame
will be sent automatically. But this OAM frame can be sent
manually using this command.
Other values : N/A
Note: Except for the “Indicate Center/Terminal MC Condition”
frame, all maintenance frames here are sent by the Center
side MC only.
Description
1 = 100Mbps
0 = 10Mbps
This bit share the same physical register as Reg. 2Ch bit 6.
1 = Full duplex
0 = Half duplex
This bit share the same physical register as Reg. 2Ch bit 5.
1 = AN enable
0 = AN disable
This bit share the same physical register as Reg. 2Ch bit 7.
1 = Reset MC sub-layer, MACs of both PHY ports and switch
fabric to their default states. This bit is self-cleared after a ‘1’ is
written to it.
0 = Normal operation
1 = Enable “Remote Command” access at Center side and
Terminal side
0 = Disable “Remote Command” access at Center side and
Terminal side
