s5EnPortExtAutoNegAdv
Module: S5-ETHERNET-COMMON-MIB
OID (symbolic): S5-ETHERNET-COMMON-MIB::s5EnPortExtAutoNegAdv
OID (numeric): 1.3.6.1.4.1.45.1.6.6.1.3.1.4
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description: A bit array that contains the bit map representing the abilities advertised during link negociation. The bit 7 tells if auto negotiation is enabled or disabled: bit 0 - 10 BASE-T half duplex capable bit 1 - 10 BASE-T full duplex capable bit 2 - 100 BASE-TX half duplex capable bit 3 - 100 BASE-TX full duplex capable
bit 5 - 100 BASE-FX full duplex capable bit 6 - 100 BASE-FX half duplex capable bit 7 - auto negotiation is enabled or disabled Only capabilites present in the hardware as indicated by s5EnPortExtHwCapability can be advertised.
If auto negotiation is enabled only bits 0-3 are used to indicate the capabilities available for negotiation. Any or all of these bits may be set as long as at least one bit is set, AND the settings are in accordance with s5EnPortExtHwCapability.
If auto negotiation is disabled one and only one of the speed setting bits MUST be set in accordance with s5EnPortExtHwCapability.
What is s5EnPortExtAutoNegAdv?
A bitmap the admin sets to control which speed/duplex combinations this port advertises during auto-negotiation, or, with bit 7 clear, to fix a single manual speed/duplex; any bits set here must be a subset of what s5EnPortExtHwCapability says the hardware can actually do.
