### Description

```asn1
cBaseTAutoNegCapabilityAdvertised OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-write
STATUS mandatory
DESCRIPTION
"A value that uniquely identifies the set of
capabilities advertised by the local NWay entity. The
value is a sum. This sum initially takes the value
zero. Then, for each additionally capability
advertised by this interface, 2 raised to the power
noted below is added to the sum. For example, an
interface which advertises the capability to support
only 100Base-TX would have a value of 256 (2**8). In
contrast, an interface which advertises both 100Base-TX
and 100Base-TX Full Duplex would have a value of
768 ((2**8) + (2**9)).
The powers of 2 assigned to the capabilities are these:
Power Capability
6 10Base-T
7 10Base-T Full Duplex
8 100Base-TX
9 100Base-TX Full Duplex
10 100Base-T4
Note that interfaces that support this MIB may
advertise capabilities that extend beyond the scope
of this MIB.
Capabilities in this object that are not available
in cBaseTAutoNegCapability cannot be enabled."
