UUID Support in Prime Network
In the absence of infrastructure monitoring tools like VCenter, the associations (hyperlinks) between 
Cisco Virtualized Packet Core (CvPC) VNE and the corresponding VCenter and UCS are not displayed 
in Prime Network. To identify a VM in the CvPC setup, UUID (a textual representation) is added in the 
physical inventory at the card level for all the virtual cards.
Viewing UUID Properties in Physical Inventory
To view UUID properties in the physical inventory:
Step 1In the Vision client, double-click the device in which the CvPC is configured.
Step 2In the VNE inventory window, expand the Physical Inventory node.
Step 3Choose Chassis > Server : Card A9K-VSM-500. The server configuration details are 
displayed in the content pane.
Step 4Choose Server : Card A9K-VSM-500 > Subslot : Subcard -A9K-MODULEv. 
The slot details configured with UUID details is displayed in the content pane.

Monitoring VSS Redundancy System
The following topics provide an overview of Cisco 6500 virtual switching redundancy system.
Cisco 6500 VSS Redundancy System Overview, page 32-1
Virtual Switch Link, page 32-4
Cisco 6500 VSS Redundancy System Overview
The Cisco Catalyst 6500 Series Virtual Switching System (VSS) allows the clustering of two chassis 
units together into a single, logical entity. The two chassis units are connected through a Virtual switch 
link (VSL) link, where one chassis acts as an active unit and the another chassis acts as a standby unit. 
If the active chassis fails, then the standby chassis act as the active chassis. The chassis units are selected 
as the active or standby units based on the priority set. 
This clustering of chassis allows enhancements in all areas of network design including high availability, 
scalability, management, and maintenance.
The VSS redundancy system has the following processors:
Dual 6500 processor—Each chassis has 1 SUP card.
Quad processor—Each chassis has 2 SUP cards, one is active and the other one is standby hot 
(switchover target). The chassis which is in standby hot (switchover target) acts as the next active 
chassis.
Viewing VSS Redundancy System Properties in Logical Inventory
To view the VSS redundancy system properties in the logical inventory:
Step 1Double-click the Cat 6500 VSS device to open the Inventory window.
Step 2Choose Logical Inventory> Redundancy Systems. Click a particular VSS domain ID. The properties 
of the VSS domain are displayed in the content pane.
Figure 32-1 shows the VSS redundancy system properties in the logical inventory

  Virtual Switch Link
Table 32-2 describes the information displayed for the VSL link:
Table 32-2  Virtual Switch Virtual Redundancy State 
Virtual Switch Link 
Any device connected to VSS system, if there is a Virtual switch link (VSL) failure from the device to 
the first active chassis, then the system internally runs SSO and creates a VSL link with the second active 
chassis. Hence there is no network failure seen in the device connected to the VSS system.
Switch Virtual Redundancy State Value Description
Active This RP is in active state
Standby HOT (Chassis) This RP is in standby state for this chassis (not 
ready to take over)
Standby HOT (Switchover Target) This RP is in standby state and ready to take over
NA Not Applicable as the system is not operating in 
VSS mode
