Cabletron Fast Ethernet Advertised Technology Ability

1.3.6.1.4.1.52.4.1.2.9.1.1.1.6

Indicates the advertised ability of the local hardware, but only becomes active on ports that have auto-negotiation enabled. For example a port which will advertise 100Base-TX(32) and 100Base-TXFD(64) ablilities would have a value of 96(32 + 64). A port that does not support auto-negotiation will be read as other(1). Values written to this object are limited to values read from ctFastEthernetLocalTechnologyAbility, excluding other(1) and Auto-Negotiation(2). Therefore if ctFastEthernetLocalTechnologyAbility has a value of 98 writing a value of 128 would result in an error. That is to say 100Base-T4 is not supported on this port. Furthermore, if ctFastEthernetLocalTechnologyAbility has a value that does not include Auto-Negotiation(2), writing any value will result in an error. That is to say that this port does not support Auto-Negotiation and therefore does not support ctFastEthernetAdvertisedTechnologyAbility. A successful set operation will result in immediate link re-negotiation if ctFastEthernetCurrentOperationalMode has a value that includes Auto-Negotiation(2)(meaning Auto-negotiation is enabled). Note: this re-negotiation will in every case cause temporary link loss during the link re-negotiation. If set to a value that is incompatible with ctFastEthernetReceivedTechnologyAbility, link negotiation will not be successful and will cause permanent link loss.
