Basic Configuration 3-7

Verify

To verify the IP address, configured and actual speed, and configured and actual duplex operations:

• Enter the show arp command to verify the IP address:

5300# show arp

Protocol Address Age (min) Hardware Addr Type Interface

Internet 172.16.254.250 _ 0800.207e.bead ARPA FastEthernet0

• Enter the show interface fastethernet 0 command to verify the configured speed:

5300# show interface fastethernet 0

FastEthernet0 is up, line protocol is up

Hardware is DEC21140, address is 00e0.1e3e.c125 (bia 00e0.1e3e.c125)

Internet address is 2.2.2.2/8

MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, rely 255/255, load 2/255

Encapsulation ARPA, loopback not set, keepalive set (10 sec), auto duplex,

100BaseTX/FX, 100Mb/s

• Enter the show controller fastethernet 0 command to verify actual speed or duplex if speed or

duplex are configured as auto:

5300# show controller fastethernet 0

DEC21140

PHY link up

Duplex mode sensed by auto-negotiation is half-duplex and Fast Ethernet speed is 100

Mbps.

• Enter the show interface fastethernet 0 command to verify the configured duplex operation:

5300# show interface fastethernet 0

Tips

If you are having trouble:

• Make sure the cable connections are not loose or disconnected.

• Make sure you are using the correct IP address.

full 10 Sets 10 Mbps for speed and full-duplex for duplex.

half 100 Sets 100 Mbps for speed and half-duplex for duplex.

full 100 Sets 100 Mbps for speed and full-duplex for duplex.
