Step 3
From the Port screen, choose the appropriate mode for each Ethernet port. Valid choices for the
E100T-12/E100T-G card are Auto, 10 Half, 10 Full, 100 Half, or 100 Full. Valid choices for the
E1000-2/E1000-2-G card are 1000 Full or Auto.
Both 1000 Full and Auto mode set the E1000-2 port to the 1000 Mbps and Full duplex operating mode;
however, flow control is disabled when 1000 Full is selected. Choosing Auto mode enables the E1000-2
card to auto-negotiate flow control. Flow control is a mechanism that prevents network congestion by
ensuring that transmitting devices do not overwhelm receiving devices with data. The E1000-2 port
handshakes with the connected network device to determine if that device supports flow control.
Step 4 Click the Enabled checkbox(s) to activate the corresponding Ethernet port(s).
Step 5 Click Apply.
Your Ethernet ports are now provisioned and ready to be configured for VLAN membership.
Step 6 Repeat this procedure for all other cards that will be in the VLAN.
