Installing and Operating Passport ARN Routers

Using the ifconfig Command
A router interface cannot communicate in an IP network without an IP address.
Because an ARN netboots over one of its serial, 56/64K DSU/CSU, Ethernet, or
token ring links, the netboot interface must have a valid IP address.
You use the interface configuration command
ifconfig
to do the following:
•
Configure the router’s initial IP interface to the network. (The initial IP
interface should be a serial interface if you are using EZ-Install.) You also use
the same procedure to configure other serial interfaces for the netbooting
procedure.
•
Configure Ethernet or token ring interfaces for the netbooting procedure.
•
Enable or disable netbooting on an interface.
Configuring an IP Serial or 56/64K DSU/CSU Interface for Netbooting
Configure a serial or 56/64K DSU/CSU (COM) interface to the IP network using
the following interface configuration command:
ifconfig
[<
synchronous_options>
]
<interface>
[
<IP_address> <subnet_mask>
[
<next_hop_address>
]]
The
synchronous options
variable indicates some combination of the following
settings:
[
-d
|
-r
[
56
|
64
]
|
-fr
[
-annexd
|
-lmi
|
-annexa
]
|
-int_clk
]
Note:
Make sure to separate command options with spaces.
