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.
