Chassis View Card Operation in a Redundant Setup
This section describes how the primary and secondary cards are shown in Chassis View when they are
in a redundant setup. The Chassis View behavior is changed based on the
CHASSIS_SHOW_PHYSICAL_MAPPING_AND_HIDE_UNMANAGED_ALARMS flag set in the
CMSCClient.conf file under the ~svplus/config directory.
When set to
false
When two cards are in a redundant relationship, the primary card (also known as the logical slot)
displays the ports and lines for all provisioning activities even if the primary slot becomes standby. No
ports and lines are shown under the secondary slot even after it becomes active.
In Chassis View, the primary card displays the ports only if they are available in the active card. The
secondary slot does not display the ports even if it becomes active.
When set to
true
• For the controller and non–controller cards:
–
When two cards are in a redundant relationship, the active card displays the ports and lines for
all provisioning and troubleshooting activities.
–
In Chassis View, the active card displays the ports only if they are available in the active card.
In a redundant setup, Chassis View displays the lines and alarms under the active card.
However, this flag does not affect the tree view and other CWM applications. The logical slot
in the tree view of a CWM application and the physical slot in Chassis View are maintained
when you select an object in one application and drag it to another application.
• For the controller card only:
–
Chassis View does not show unmanaged or unsupported alarms for PXM and RPM cards and
unmanaged alarms for MGX nodes, such as the HIST and ACO alarms on the PXM cards.
–
Chassis View does show the following in the active controller card: the shelfIntegrated alarm
for MGX nodes, physical mapping (alarms and ports or lines) for redundant cards, and alarms
that are similar to DCA, DCB, and ENET.
–
Chassis View displays an Empty Reserved controller card as a blank card in the front view.
–
If no back card or no secondary back card exists, Chassis View displays either card as a blank
back card in the rear view.
RPM Card Behavior based on the Chassis View Flag Value
When the CHASSIS_SHOW_PHYSICAL_MAPPING_AND_HIDE_UNMANAGED_ALARMS flag
value is set to true in the CMSCClient.conf file, unmanaged alarms, such as the CB_TX and CB_RX
alarms on the RPM cards, are not shown in the RPM card in Chassis View.
Chassis View Operation after Card and Line Switchover
For a card switchover in a redundant setup, Chassis View behavior depends on the
CHASSIS_SHOW_PHYSICAL_MAPPING_AND_HIDE_UNMANAGED_ALARMS flag value set in
the CMSCClient.conf file.
After line switchover, provisioning is allowed only on the working line of an automatic protection
switching (APS) pair, whether the line is currently active or not. However, both the working and
protection lines are monitored.
