Chapter 4 Using the Command-Line Interface for Quick Configuration
Configuring Ethernet Interfaces
Step 3 The system prompts you for the subnet mask for the Ethernet 2 (Public) interface. The entry in brackets
is the standard subnet mask for the IP address you entered above. For example, an IP address of
192.168.12.34 is a Class C address, and the standard subnet mask is 255.255.255.0.
> Enter Subnet Mask for Ethernet 2
Quick -> [ 255.255.255.0 ] _
At the cursor, enter the subnet mask for Ethernet 2, using dotted decimal notation; for example,
255.255.255.0. To accept the default, press Enter.
Step 4 The system prompts with a menu to set the speed for the Ethernet 2 interface. You can let the VPN
Concentrator automatically detect and set the appropriate speed (the default), or you can set fixed speeds
of 10 or 100 Mbps per second (for 10BASE-T or 100BASE-T networks). If you accept the default, be
sure that the port on the active network device (hub, switch, or router) to which you connect this interface
is also set to automatically negotiate the speed. Otherwise, select the appropriate fixed speed.
1) Ethernet Speed 10 Mbps
2) Ethernet Speed 100 Mbps
3) Ethernet Speed 10/100 Mbps Auto Detect
Quick -> [ 3 ]
At the cursor, enter the menu number for your selection; for example, 1. To accept the default (3), press
Enter.
Step 5 The system prompts with a menu to set the transmission mode for the Ethernet 2 interface. You can let
the VPN Concentrator automatically detect and set the appropriate mode (the default), or you can
configure the interface for full duplex (transmission in both directions at the same time) or half duplex
(transmission in only one direction at a time). If you accept the default, be sure that the port on the active
network device (hub, switch, or router) to which you connect this interface is also set to automatically
negotiate the transmission mode. Otherwise, select the appropriate fixed mode.
1) Enter Duplex - Half/Full/Auto
2) Enter Duplex - Full Duplex
3) Enter Duplex - Half Duplex
Quick -> [ 1 ] _
At the cursor, enter the menu number for your selection; for example, 2. To accept the default (1), press
Enter.
Step 6 The system prompts with a menu giving choices for proceeding. You can configure other interfaces, save
your current entries, continue on to other quick configuration parameters, or exit the CLI. We
recommend that you save first.
