ifMauAutoNegCapability

Module: MAU-MIB

OID (symbolic): MAU-MIB::ifMauAutoNegCapability

OID (numeric): 1.3.6.1.2.1.26.5.1.1.5

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: ********* THIS OBJECT IS DEPRECATED **********

This object has been deprecated in favour of ifMauAutoNegCapabilityBits.

A value that uniquely identifies the set of capabilities of the local auto-negotiation entity. The value is a sum that 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 that has the capability to support only 100Base-TX half duplex would have a value of 32768 (2**15). In contrast, an interface that supports both 100Base-TX half duplex and 100Base-TX full duplex would have a value of 98304 ((2**15) + (2**16)).

The powers of 2 assigned to the capabilities are these:

Power Capability 0 other or unknown (1-9) (reserved) 10 10BASE-T half duplex mode 11 10BASE-T full duplex mode 12 (reserved)

13 (reserved) 14 100BASE-T4 15 100BASE-TX half duplex mode 16 100BASE-TX full duplex mode 17 (reserved) 18 (reserved) 19 100BASE-T2 half duplex mode 20 100BASE-T2 full duplex mode

Note that interfaces that support this MIB may have capabilities that extend beyond the scope of this MIB.

What is ifMauAutoNegCapability?

A deprecated bitmap encoding this interface's local auto-negotiation capabilities, superseded by ifMauAutoNegCapabilityBits and kept only for backward compatibility with older tools.

Examples

Walk all instances (SNMPv2c):
