etherPortAutonegAdvSpeed
Module: PORT-MIB
OID (symbolic): PORT-MIB::etherPortAutonegAdvSpeed
OID (numeric): 1.3.6.1.4.1.5812.3.3.1.30
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This specifies what speed capability is advertised for autonegotiation. If 100 MBPS is set, then 10 MBPS is also advertised.This does not apply to Gig Ethernet Phys, since they do not autonegotiate speed or duplex.
What is etherPortAutonegAdvSpeed?
This sets which speed capability (10, 100, or 1000 Mbps) the port advertises during autonegotiation. Advertising 100 Mbps automatically also advertises 10 Mbps as a fallback, per standard autonegotiation rules, though this object doesn't apply to Gigabit Ethernet PHYs since they don't autonegotiate speed. An admin restricts advertised speeds here to force a link to a specific tier, for example limiting an uplink to 100 Mbps to match an older switch.
