This object is used to specify the port speed and duplex abilities to be advertised during link negotiation.

bit 0 - 10 half duplex advertised bit 1 - 10 full duplex advertised bit 2 - 100 half duplex advertised bit 3 - 100 full duplex advertised bit 4 - 1000 half duplex advertised bit 5 - 1000 full duplex advertised bit 6 - Mac PAUSE frame support advertised bit 7 - Asymmetric PAUSE frame support advertised bit 8 - No advertisements

The abilities specified in this object are only used when auto-negotiation is enabled on the port. If all bits in this object are disabled, and auto-negotiation is enabled on the port, then the physical link process on the port will be disabled (if hardware supports this ability).

Any change in the value of this bit map will force the PHY to restart the auto-negotiation process. This will have the same effect as physically unplugging and reattaching the cable plant attached to this port.

The capabilities being advertised are either all the capabilities supported by the hardware or the user- configured capabilities which is a subset of all the capability supported by hardware.

The default value for this object will be all the capabilities supported by the hardware.

Note that bit 6 and bit 7 are currently not supported in ERS8600/ERS8800.
