Note: Using the ARP utility may require administrator rights.
To assign the Ethernet/hardware address using the ARP utility:
1. At the command prompt, type
ARP-A
to verify that there is at least one entry in the ARP table. If there
is at least one entry, proceed to Step 3.
2. If there is no other entry listed in the ARP table besides the local machine, ping another IP machine on
the network to build the ARP table. You must ping a host other than the machine on which you are
working.
3. After the entry is listed in the ARP table, use the following command to ARP the IP address:
arp -s <IP Address> <Ethernet/Hardware Address>
where the
<IP address>
is the numerical address (example: 192.168.002.203 ) and the
<Ethernet/Hardware Address>
is the address labeled on the Micro Serial Server device
(example: 00-80-a3-2b-02-3b ).
Note: The ARP/ping method only works during the first two minutes of LNL-ETHLAN-MICR
operation. If this process is not completed in time, then the LNL-ETHLAN-MICR must be
rebooted and the ARP/ping process redone.
4. Ping the IP address to have the device acknowledge the IP assignment. There should be replies from the
IP address if the ARP command was accepted.
Note: The ETHLAN-MICR will not save this learned IP address permanently; this procedure is
intended as a temporary measure to allow an administrator to Telnet into the LNL-ETHLAN-
MICR for configuration. Once the power is recycled on the device, the IP programming that is
done with the arp command will be lost.
After doing this, telnet into the IP address to complete the rest of the device configuration. For more
information, refer to
Establish Network Communication on page 44.
Important: In Establish Network Communication, it is critical to perform Step 3 (
change
ipaddress <your ip address>
) in order to lock in the temporary IP
address assigned by the ARP process. This step makes the IP address static
within the device.
Note: BOOTP and RARP are disabled using commands when configuring the device for use. DHCP
is disabled when the device is shipped from Lenel. However, if an NVR reset is performed on
the device, DHCP, BOOTP, and RARP will all be re-enabled and if there is a DHCP server on
the network the unit will obtain an IP address automatically and you will not be able to use the
ARP command for programming. If there is no DHCP server on the network, the DHCP option
