### Description

```asn1
cBaseTAutoNegCapability OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"A value that uniquely identifies the set of
capabilities of the local Autonegotiation entity. The
value is a sum which initially takes the value zero.
Then, for each capability of this interface, 2 raised
to the power noted below is added to the sum. For
example, an interface which has the capability to support
only 100Base-TX would have a value of 256 (2**8). In
contrast, an interface which supports 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 have
capabilities that extend beyond the scope of this MIB."
