Troubleshooting Strategy Overview
Cisco WAN Manager
Cisco WAN Manager is part of the Cisco Service Management System. Cisco WAN Manager includes
tools that operators of service provider networks and large enterprise networks can use to provision and
manage their networks. The Cisco WAN Manager provides fault-management features and can be used
along with other applications such as CiscoView, the Event Browser, and Configuration Save and
Restore.
Use Cisco WAN Manager to perform search, sort, and filter operations, and to tie events to extensible
actions. For instance, Cisco WAN Manager can page someone upon receiving a certain type of SNMP
trap. It supports alarm hierarchies that report the root cause of problems to operators and higher-level
systems.
Configuration Save and Restore saves a snapshot of the entire network configuration. For disaster
recovery, operators can selectively restore configurations of any element, from a single node up to the
entire network. This restoration ability significantly reduces recovery time when a catastrophic failure
occurs.
The Cisco WAN Manager Trivial File Transfer Protocol (TFTP) statistics collection facility offers the
ability to obtain extensive usage and error data across machines and platforms.
A wide range of statistics is available at the port and virtual channel level including the following:
• Connection statistics
• Circuit line statistics
• Packet line statistics
• Frame Relay port statistics
• Network statistics
• Physical layer statistics
• Protocol layer statistics
Use the Cisco WAN Manager application to manage several Cisco products. Use the
Cisco WAN Manager on the Cisco PGW 2200 Softswitch platform to manage Cisco SS7 interfaces and
other switches. See the Cisco WAN Manager documentation for more information.
Cisco MGC Node Manager
The Cisco MGC Node Manager (CMNM) is an element management system that is based on the
Cisco Element Management Framework (CEMF). It is responsible for managing the
Cisco PGW 2200 Softswitch platform, including the Cisco PGW 2200 Softswitch, other switches, and
Cisco SS7 interfaces.
NMS design divides network management into five discrete areas: Fault, Configuration, Accounting,
Performance, and Security. The Cisco MNM provides fault and performance management of the
Cisco PGW 2200 Softswitch, as well as flow-through provisioning of the Cisco PGW 2200 Softswitch
and its subcomponents. In addition, MNM provides fault and performance management of the Cisco SS7
interfaces and switches. MNM uses the Cisco Voice Services Provisioning Tool (VSPT) to enable
configuration of the Cisco PGW 2200 Softswitch and uses CiscoView to configure the Cisco SS7
interfaces and switches.
The CEMF platform provides security and some accounting features. MNM does not provide any
security or accounting features beyond the features that the CEMF provides. MNM operates separately
with a customer-operations support system or a Cisco NMS such as the Voice Network Manager (VNM).
