Release Notes for the Cisco WAN Manager, Release 15.3.00 P1
OL-11190-01, Rev. C0
CWM Feature Limitations
• The Configurator can be started on either the primary CWM or the secondary CWMs, but devices
can be added, modified, or deleted using the Configurator only on the primary CWM.
• The CWM gateway role is undefined or unknown when links between the primary and
corresponding secondaries are unstable. When a CWM gateway is in an undefined or unknown role,
a core dump sometimes occurs.
All of the above CWM-to-CWM communication limitations listed also apply to the SCM gateway.
Network Monitor Limitations
Network nodes are managed differently depending on the network configuration. See the
following configurations:
• In a single routing node PNNI network, the node is managed by using the IP address specified in the
network.conf file.
• In the case of a PXM45-based or PXM1E-based MGX network, these PXM45-based or
PXM1E-based MGX nodes are managed by using the primary IP address, which is specified by
using the cnfndparms command and specifying Option 7 or 8 (depending on chassis type).
Configure the trap IP address with the primary IP address.
• PXM1-based MGX nodes connected to PXM45-based MGX nodes are managed through the atm0
IP address. If atm0 is not set, the LAN IP address is used to manage the PXM1-based MGX nodes.
Use the cnftrapip command to configure the trap IP address accordingly.
As of CWM 15.0.00 and later, the SHOW_TOPO_VIEW flag in the CMSCClient.conf file is used to
configure if nodes and trunks are displayed in the topology display of the Network Monitor application
at CWM startup. Each flag determines what you see when the NWTopology opens:
• SHOW_TOPO_VIEW 1 = You see nodes and trunks in the topology.
• SHOW_TOPO_VIEW 0 = You cannot see nodes and trunks in the topology.
In releases prior to CWM 15.0.00, a flag named TOPO_SHOW_MAP in the
/usr/users/svplus/config/CwmGs.conf file was used to configure if nodes and trunks were displayed in
the topology display of the Network Monitor application at CWM startup. Because this flag is now
obsolete, you should use the SHOW_TOPO_VIEW flag in the CMSCClient.conf file instead.
Chassis View Operation
This section describes different aspects of the Chassis View operation in the CWM:
• Chassis View Card Operation in a Redundant Setup, page 32
• RPM Card Behavior based on the Chassis View Flag Value, page 32
• Chassis View Operation after Card and Line Switchover, page 32
