The Card must now be reset by either pressing the reset button on the faceplate or
by typing sysReboot at the command line interface. When the card has rebooted,
the operation of the network interface can be tested by using the "ping" command.
 ping "mm.nn.oo.pp",3
Where mm.nn.oo.pp is another IP address in the network that should be accessible
from the Nortel Remote Agent Observe card and 3 denotes that 3 ping packets will
be sent out to the other IP address.
This should result in output similar to that shown below:
> ping "47.85.3.41", 3

DHCP IP Address Assignment
DHCP is used to determine the network configuration of each Nortel Remote
Agent Observe card in a dynamic fashion. DHCP aims to reduce the work
necessary to administer an IP network by using a server to allocate network
addresses. DHCP also allows automatic reuse of addresses by specifying a lease
time. Clients must renew the lease periodically.
The client (Nortel Remote Agent Observe Card) first broadcasts a discover
message containing its Ethernet address as a client identifier. A DHCP server then
replies with an offer message, containing configuration parameters. The client can
receive offers from multiple DHCP servers. The client must then select a server by
broadcasting a request message containing the server identifier. The server then
acknowledges the reply and assigns the configuration to the client. The client can
now use the assigned configuration.
The DHCP server should assign a reserved address to the card to guarantee that the
card always receives the same IP address. Otherwise, the card must have an
assigned DNS name to ensure that it can always be found using a Web Browser. If
the local DHCP server provides long lease periods, this may not be necessary.
