Chapter 3 Configuring the Cisco 1604 Router

Verifying the Ethernet Interface Configuration

Step 3 Establish connectivity with an Ethernet-based device. In this example, IP address 10.1.4.2 is assigned to the first external PC on this LAN to test for router-to-PC connectivity. The PC’s DOS prompt application is opened and the ping 10.1.4.1 command is issued.

C:\WINDOWS> ping 10.1.4.1

Pinging 10.1.4.1 with 32 bytes of data:

Reply from 10.1.4.1: bytes=32 time=3ms TTL=236

Reply from 10.1.4.1: bytes=32 time=2ms TTL=236

Reply from 10.1.4.1: bytes=32 time=3ms TTL=236

Reply from 10.1.4.1: bytes=32 time=2ms TTL=236

Step 4 Ping the PC from the Cisco 1604. If the PC has not yet used any IP services or drivers, the connection might fail. The preferred method is to ping the router from a PC on the LAN first:

robo-austin# ping 10.1.4.2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.1.4.2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 4/5/8 ms

Step 5 If you know that the Ethernet interface is up but not performing correctly, enter the show interface ethernet 0 command. This example shows errors in the counters because the Ethernet cable was not plugged in:

robo-austin#show interface ethernet 0 Ethernet0 is up, line protocol is up
