Global Configuration Mode
From the global configuration mode, you can make configuration changes that
apply to the entire router and all interfaces. You can configure the system's
global parameters, such as the hostname, passwords, and banners. You can
also set parameters for IP services such as DHCP and DNS. You can enable
the built-in firewall and configure global options for that firewall. You can also
configure passwords to protect the enable mode and SSH, FTP, and HTTP
access.
From the global configuration mode context, you can also access other
configuration mode contexts to configure specific router interfaces and func-
tions, such as routing protocols. There are four main types of contexts:
interface
router
line
other
Interface. The interface configuration mode contexts enable you to config-
ure the LAN and the WAN connections to your router. To configure an
interface, enter the following command from the global configuration mode
context:
Syntax: interface <interface> [<slot>/<port> | <interface number>]
Replace <interface> with the type of physical interface such as e1, t1, serial,
bri (for ISDN interfaces), adsl, or modem (for analog backup interfaces). You
can also replace <interface> with a logical interface such as ppp, frame-
relay, loopback, or tunnel. For physical interfaces, replace <slot>/<port>
with the slot and port location of the connection, and for logical interfaces,
replace <interface number> with the interface number.
For example, if your router has a T1 module in slot one, you would type
interface t1 1/1 to configure this interface. The CLI prompt will change to
show that you are in the T1 1/1 interface configuration mode context:
ProCurve(config)# interface t1 1/1
ProCurve(config-t1 1/1)#
For another example, if you want to configure a PPP connection to an ISP, you
would enter interface ppp 1 to create and configure a PPP logical interface.
