Step 2
Verify that the Fast Ethernet interface is up. Ping the default gateway.
5800-NAS#ping 172.22.66.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.22.66.1, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 1/1/1 ms
5800-NAS#
This step verifies that you have IP connectivity with another device on the subnet. If the ping succeeds
to the default gateway, try pinging the DNS server in your backbone. Make sure the backbone is
configured to get to the access server; otherwise, the ping will not work. Configure the backbone routers
to support the routes to the networks you are using.
Note
An 80% ping-success rate is normal for the first time you ping an external device.
The NAS does not yet have an ARP entry (address resolution protocol) for the
external device. A 100% success rate is achieved the next time you ping the
device.
