Chapter 1 Interfaces Speed Setting for 10/100Base-T When the router is set to auto-negotiation enable, the following is the correct behavior of the Ethernet with each setting: 1. 10mbps Half Duplex Use parallel detection because the Ethernet is using force mode and thus has auto-negotiation disabled. PORs to Half Duplex. Resets to Half Duplex. Reconnection at switch maintains Half Duplex. 2. 10mbps Full Duplex Use parallel detection because the Ethernet is using force mode and thus has auto-negotiation disabled. PORs to Half Duplex. Resets to Half Duplex. Reconnection at switch maintains Half Duplex. 3. 100mbps Half Duplex Use parallel detection because the Ethernet is using force mode and thus has auto-negotiation disabled. PORs to Half Duplex. Resets to Half Duplex. Reconnection at switch results in Half Duplex. 4. 100mbps Full Duplex Use parallel detection because the Ethernet is using force mode and thus has auto-negotiation disabled. PORs to Half Duplex. Resets to Half Duplex. Reconnection at switch results in Half Duplex. 5. Ethernet in Auto mode in 100mbps FD environment Use auto negotiation to the highest common local and remote capability, i.e. 100FD in this case. PORs to 100/FD. Resets to 100/FD. Reconnection at switch remains 100/FD. 28
