The term switch stack refers to a combined module that consists of several network switches bridged together with the aim of delivering maximum scalability and performance.
All Cisco switch stacks consist of the following components:
Each stack has an unique IP address that is linked to the master switch. Stacking is widely approved as the most effective, flexible, and scalable mode for increasing the capacity of a network, and it is important to monitor switch stacking for their availability and performance.
Switch stacks contain several individual switches but exist as a single entity. It's difficult to mark and troubleshoot a problematic switch from the group of available switches. Monitoring Cisco stacking switches is a complicated process and requires precise and extensive methods to be followed. In-depth switch stack monitoring is needed to remotely detect and troubleshoot the problematic switch.
OpManager now supports Cisco switch stack monitoring for versions 125300 and above. A combined interface with a unified SNMP/CLI view is provided for all units in a stack that is discovered in OpManager. The device snapshot page displays the availability status of all individual switches bundled within the stack. This Cisco switch stack management feature helps you monitor an entire stack with complete focus on all individual switches in the stack. Switch stacks can be discovered in OpManager individually from the Add Device page or as bulk from theNetwork Discovery page.
Stack topology is a graph representation of the data port connectivity between various switches in a stack along with the status of that switch. This data is fetched from the stack port information of the discovered stack. This varies from time to time based on the switch state, switch number, role, and more. OpManager makes use of this stack port information from the master switch and plots the topology map accordingly.
Stack details: The stack details table gives you information on the currently acting master switch, the bandwidth consumed by the switch stack, and the number of problematic switches in the stack.
The switch stack table is similar to that of a device inventory. OpManager fetches the following inventory information automatically upon discovering a switch stack.
The stack sensor details widget gives you a consolidated view on the status of all hardware sensors associated with the switch stack such as fan, power supply, temperature, and voltage sensors. This allows you to monitor the status of all available hardware sensors at any given time remotely. For detailed information, you can further drill down by clicking a sensor link to be redirected to the corresponding hardware monitor details page. This gives all the necessary switch-wise sensor information.
OpManager keeps network administrators informed about the changes done to all the monitored stacks in your environment. OpManager generate alerts exclusively for switch stacks and informs the user when:
You can associate custom performance and script monitors, configure thresholds, and generate notifications for the alerts generated. You can also generate reports on availability and performance statistics for the discovered switch stack.
