Additional CWM Release 10 Applications and Features

Configuration Save and Restore

The ConfigSave and Restore feature can be found under the Tools pull down menu of the CWM
Topology Main Window. This feature enables you to save a snapshot of the entire network’s
configuration on CWM. In a disa ster r ec over y scen ar io , yo u can se lectively restore a single node’s
configuration, or restore the configuration of the entire network on a node by node basis. This feature
significantly reduces time to recover in the unlikely e vent of a catastrophic failure . You can also use the
Save and Restore feature to restore a previous configuration after making a series of incorrect or
temporary changes.

Network Configurator

The Network Configurator is a new Java-based applicati on for Release 10 of CWM that enables users to
add new nodes, or modify or delete exi sting node s. It is also use d to provi de des criptor informa tion, no de
name, and IP address information for the nodes i n yo ur net wor k. The Network Config urator is start ed
by entering runConfigurator <machine name> <login> <password> on a shell’s command line,
where Cisco WAN Manager Release 10 is installed. The Network Configurator main window appears,
allowing the user to add, delete, and modify nodes.

CWM to CWM Communications

Release 10 of Cisco WAN Mana ger has been designed to enable multiple CW M workstations to ma nage
a network with improved n e t wo r k synchronization and s c alability. Due to the size an d growth of
networks, it is faster to retrieve initial network information from another CWM workstation that is
already running and synchronized with the network.
A new CWM feature now enables users to continue the provisioning of network data, even when
communications between a Primary CWM and Secon dary CWM ha ve been interrup ted. If for any rea son
the communications betw een CWM servers are interrup ted, user data provisioni ng will be suspended on
the Secondary CWM, but user data provisioning will continue on the Primary CWM. During that time,
the provisioning of user data and mon itoring of the ne twor k are not impac ted. T his is c alled the De graded
Mode of Operation, and is discus se d in Chap te r 11, CW M- CW M Comm un ic ation s.
Release 10 of CWM uses an in d ust ry st an da rd CORBA architecture to implemen t the communications
between two or more CWM work s tat io ns. Th e a rchitecture uses a server-client stru ctu r e f o r
communications between the CWM server and client processes.

Access to IGX, BPX, and MGX Networks

IGX, BPX, and MGX switches provide an Ethernet 802.3 AUI LAN interface to CWM for network
management control and information. An entire network can be managed through an Ethernet
connection on a single WAN switch or through multiple Ethernet interfaces distributed throughout the
network. Cisco WAN switches u s e T C P /I P ove r Ethernet to commun ic ate between CWM netwo rk
management workstations and the WAN switch. Telnet support is also available to enable LAN-based
workstations access to the IG X, B P X, o r MGX m anagement interface.
