Nortel Networks 14.2 manual Ifconfig Command Options for a Serial Interface

Configuring Remote Access for AN and Passport ARN Routers

Table 4-2.	ifconfig Command Options for a Serial Interface
Option		Description
-d		Resets the router’s IP interface options to the default values. This
		option tries four WAN configurations in the following order, until it finds
		the correct type for the router’s connection to the network:
		1. Nortel Networks HDLC encapsulation (also called
		Nortel Networks Standard PPP) with external clocking
		2. Frame Relay Annex D
		3. Frame Relay LMI
		4. Frame Relay Annex A
-fr		Configures the router’s serial port as a frame relay connection. With
		this option, use one of the following options to specify a DLCMI
		option: -annexd,-annexa, or -lmi.
-annexd		When one of these options is used with the -froption, it specifies a
-annexa		DLCMI option. Use the same option as the network to which the
-lmi		router’s Frame Relay interface is connected. The default option for
		Frame Relay is -annexd.
-int_clk		Sets the serial port to internal clocking at 1.25 MB/s. If you do not
		specify this option, the router defaults to external clocking.
<interface>		Specifies the IP connector you are configuring. Use the format
		com<port_no.>.
<IP_address>		Specifies the IP address of the interface you set with <interface>.
		Provide this address in dotted-decimal notation.
<subnet_mask>		Specifies the IP subnet mask of the interface you set with <interface>.
		Provide this address in dotted-decimal notation.
<next_hop_		Specifies the IP address of the next-hop router. Provide this address
address>		in dotted-decimal notation. Specify this address only if there are
		intermediate routers between the AN/ANH or ARN router and the
		BootP server.
