# arp –s 192.168.20.127 00:80:92:01:00:D2 temp
The Ethernet address (MAC address) 00:80:92:01:00:D2 in the above
example can be determined from the network card self-diagnostic test
which can be printed by pressing the push-button on the network card for
two seconds and then releasing it.
3. Use the ping command to confirm the connection with the network
interface card.
Example: for IP address 192.168.20.127
# ping 192.168.20.127
If there is no reply, there is a problem with the configuration of the IP
address (the IP address has been already set manually or DHCP/RARP
server may run), or with the network. Reset the network interface card
settings to default and try to set temporary IP address.
If you still have the problem after resetting the network interface card,
consult the network manager.
4. Log in to the network interface card using TELNET.
Example: Logging in to IP address 192.168.20.127
#telnet 192.168.20.127
Trying 192.168.20.127
Connected to 192.168.20.127
