Enabling and Disabling Interfaces with ifconﬁg

To enable or disable an ARN interface for the network boot process, use the following command formats:

ifconﬁg -disable <interface> ifconﬁg -enable <interface>

Table A-4 describes the ifconﬁg command arguments for enabling and disabling interfaces for network booting.

Table A-4.	ifconﬁg Settings to Enable and Disable Netboot Interfaces

Setting		Description

<interface>		Speciﬁes the IP connector you are enabling or disabling for network
		booting. Use one of the following formats:
		xcvr<port #>
		com<port #>
		mau<port #>

ifconﬁg Command Examples

1.Conﬁgure the current interface for the default Netboot procedure. ifconﬁg -d

2.Specify the IP address and subnet mask of the base module Ethernet interface. ifconﬁg xcvr1 21.3.5.62 255.255.255.0

3.Specify the IP address and subnet mask of the expansion module Ethernet interface.

ifconﬁg xcvr2 21.3.5.61 255.255.255.0

4.Conﬁgure the IP address and Frame Relay DLCMI of the third serial interface on the expansion module.

ifconﬁg com3 21.3.5.62 -fr -annexa

5.Specify the IP address and subnet mask of the base module token ring interface.

ifconﬁg mau1 21.3.4.77 255.255.255.0
