Configuring the Switch Modules using the Menu-driven Interface 
—  Backpressure—Toggle to enable or disable backpressure flow control in and out of 
the switch. When backpressure is enabled and there is incoming traffic congestion on 
a 10/100 port, the receiving port sends a request to the transmitting port. The 
transmitting port acknowledges the request and stops sending packets for a random 
amount of time, before it starts sending again. 
—  SNTP—Toggle to enable or disable Simple Network Time Protocol (SNTP). For 
additional information, refer to the “Configuring the Switch Module Date and Time” 
section later in this chapter.  
3.  After making your changes, highlight APPLY, then press the Enter key. 
 
IMPORTANT:  To save the configuration settings permanently, you must enter them into NVRAM using 
the Save Changes option on the main menu. Refer to the “Saving Changes” section earlier in this 
chapter.  
Configuring Port Settings 
This section describes how to configure the following port settings: port name, speed/duplex 
parameter, and flow control state. Refer to the “Configuring Port Security” section later in 
this chapter for information on how to set the port security parameters. 
The speed-duplex parameter for each port can be set to 1000M/Full, 100M/Full, 100M/Half, 
10M/Full, 10M/Half, or Auto. The Auto setting allows the port to automatically determine 
the fastest settings that the device the port is connected to can handle.  
 
IMPORTANT:  In the forced 100M/Full, 100M/Half, 10M/Full, and 10M/Half modes, auto MDI-X is 
disabled and a cross-over cable must be used. 
To configure ports: 
1. Highlight Configure Ports from the Configuration menu. 
2. Press the Enter key. The following screen is displayed. 
 
The Configure Ports screen allows you to configure the name, speed-duplex, and flow 
control for each port
