Configuring 10/100 Auto-Sensing Ports

The 10/100cfg command allows you to enable auto-negotiation, as well as configure link
speed (10 or 100 Mbps) and the link mode (full or half-duplex) on 10/100 Ethernet ports on
the ESX-K-100C-32W modules on the Omni Switch/Router.
Follow these steps to configure a 10/100 port:
1. Enter 10/100cfg at the system prompt and press <Enter>.
2. The system displays a prompt asking for the slot and port number:
Enter Slot/Interface :
Enter the slot number, a slash (/), and the port number of the Ethernet port that you want
to configure. Press <Enter>.
3. The system prompts you to enable or disable auto-sensing:
Autonegotiate [y,n, or quit] (Currently enabled (y)) :
Enter y to enable auto-negotiation or n to disable auto-negotiation. Auto-negotiation can
be used to determine the link speed and the link mode (full or half) of the connection.
If you choose y to enable auto-negotiation, the system will automatically detect whether
the connection speed of the attached device is 10 Mbps or 100 Mbps. It can also deter-
mine whether the link mode of the connection is half- or full-duplex.
♦ Note ♦
Auto-negotiated ports on GSX modules display inactive
ports as 1000 Mbps/full duplex.
If you enable auto-negotiation, continue with Step 6.
If you choose n to disable auto-negotiation, then you will be prompted for the Line
Speed. Continue on with the next step.
4. If you chose to disable auto-sensing, then the following prompt displays showing the
current line speed:
Line Speed [100 or 10] (Currently 100) :
Select whether you want the port to operate at 10 Mbps or 100 Mbps. The port will oper-
ate at this speed until you change it through the 10/100cfg command later. Press <Enter>
after you enter the Line Speed. The new line speed will take effect; no reboot is required.
Continue with the next step.
5. The following prompt displays, showing the current link mode:
Link Mode [Full, Half] (Currently (H)alf Duplex) :
Enter F to set the port to full-duplex mode or H to set the port to half-duplex mode. In
full-duplex mode, the full 100 or 10 Mbps of bandwidth is used for data traveling on each
direction of the cable. Press <Enter> after you enter the Mode. The new mode will take
effect; no reboot is required. You have completed the configuration of this port.
