Chapter 3 Initially Configuring the Cisco DSLAM
Configuring IP Interface Parameters
You define subnet mask bits as a decimal number between:
• 0 and 22 for Class A addresses
• 0 and 14 for Class B addresses
• 0 and 6 for Class C addresses
Note Do not specify 1 as the number of bits for the subnet field. That specification is reserved by
Internet conventions.
To configure the IP address, perform the following steps, beginning in global configuration mode:
Example
This example shows how to configure the Ethernet CPU interface 0/0 with IP address 172.20.40.93 and
subnetwork mask 255.255.255.0, and displays the interface information:
DSLAM# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
DSLAM(config)# interface ethernet 0/0
DSLAM(config-if)# ip address 172.20.40.93 255.255.255.0
DSLAM(config-if)# end
DSLAM# show interface ethernet 0/0
Ethernet0/0 is up, line protocol is up
Hardware is AmdP2, address is 0001.64ff.a97f (bia 0001.64ff.a97f)

Command Task
Step 1
DSLAM(config) interface ethernet slot/port Select the interface to be configured.
Step 2
DSLAM(config) ip address A.B.C.D sub_net_A.B.C.D Configure the IP and subnetwork address.
