IP Addressing
Guidelines
IP Networks and Proxy ARP
On the proxy node:
• The Proxy ARP parameter must be enabled on the management gateway node. In
Map View, click a node, click the Config tab, and change the value in Proxy ARP
to enabled.
bp-dcn-gw
-ip
Required
for each
bp-dcn-i
p
If the node is connected directly to the management
server, this address is the IP gateway of the
management server.
If there is a router between the management server
and this node, this address is the IP address of the
port on the router connected to the Ethernet
interface on the back of the Traverse node.
Depends on site
practices.
ems-ip Required if
there is a
router
between this
node and
the
managemen
t server.
This address is the IP address of the TransNav
management server.
This IP address must be on a separate network from
any node-ip and gcm-{a | b}-ip.
For in-band management, this address must be on
or routed to the same network as the bp-dcn-ip of
the management gateway node (the node with the
physical connection to the management server).
For out-of-band management, this address must be
connected or routed to all bp-dcn-ip addresses.
Depends on site
practices.
ems-gw-ip Required
for each
ems-ip.
This address is the IP address of the port on the
router connected to the Ethernet interface on the
back of the Traverse shelf. This address is the same
address as bp-dcn-gw-ip.
Depends on site
practices.
ems-mask Required
for each
ems-ip.
Required if there is a router between the node and
the management server. This address is the address
mask of the IP address on the management server
(ems-ip).
Depends on site
practices.
proxy-arp Required on
the node
acting as
proxy server
for the IP
subnet.
Enable this parameter if this node is to be used as
the proxy server for the IP subnet.
The bp-dcn-ip and the node-ip of the proxy node
must be the same IP address.
Once you plan the network with one node as the
proxy, you cannot arbitrarily re-assign another node
to be the proxy ARP server.
Depends on
network plan and
site practices.
