Speed Setting for 10/100Base-T
When the router is set to auto-negotiation enable, the following is
the correct behavior of the NIC with each setting:
1. 10mbps Half Duplex
Use parallel detection because the NIC is using force mode
and thus has auto-negotiation disabled.
PORs to 10mbps Half Duplex. Resets to 10mbps Half Duplex.
Reconnection at switch maintains 10mbps Half Duplex.
2. 10mbps Full Duplex
Use parallel detection because the NIC is using force mode
and thus has auto-negotiation disabled.
PORs to 10mbps Full Duplex. Resets to 10mbps Full Duplex.
Reconnection at switch maintains 10mbps Full Duplex.
3. 100mbps Half Duplex
Use parallel detection because the NIC is using force mode
and thus has auto-negotiation disabled.
PORs to 100mbps Half Duplex. Resets to 100mbps Half
Duplex. Reconnection at switch results in 100mbps Half
Duplex.
4. 100mbps Full Duplex
Use parallel detection because the NIC is using force mode
and thus has auto-negotiation disabled.
PORs to 100mbps Full Duplex. Resets to 100mbps Full
Duplex. Reconnection at switch results in 100mbps Full
Duplex.
5. NIC 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.
