Networking
The primary goal of your Cisco WAN Manager (CWM) network design is to build the simplest, most
economical communication network possible while enabling both flat and tiered networks.
Determination of the number and placement of CWM workstations throughout the network is largely
dependent on the amount of message traffic between CWM and the nodes within the network, and the
ability of either CWM or the individual MGX™ 8850 series, BPX® 8600 series, or IGX™ 8400 series
nodes to process the messages. As each component in the network owns indigenous factors that
contribute to overall performance, a key issue becomes understanding the limitation of each component
and determining which component is the limiting factor in the network design.
Connecting to Cisco WAN Manager
Each CWM workstation resident within a network must be able to communicate with all nodes within
the network.
Each node can have two different IP addresses. The first is the network IP address. You configure the
network IP address on a switch by invoking the cnfnwip command from the Switch Command Line
Interface (CLI). The network IP address is used by CWM to communicate with all nodes in the network.
The second type of IP address, is the LAN IP address. It is configured on a switch by invoking the cnflan
command from the Switch CLI. CWM uses the LAN IP address for communicating with a gateway node
and all feeder nodes.
Note The network and LAN IP addresses should be configured on all of the nodes that are to communicate
directly with CWM. All nodes that communicate with the CWM workstation through a gateway node do
not need a LAN IP address. These nodes use the network address via the trunks between nodes and are
in-band.
Following are descriptions of various components found in a CWM network:
Cisco WAN Manager Gateway Node
A Gateway node provides topology and other vital information about the network to CWM. The Gateway
node name is specified in the /usr/users/svplus/config/network.conf file on the CWM workstation.
