The active and standby exchange control traffic between one another, as well as with the member devices. Problem - Unexpected Reload of One or More Members Use verification commands provided later in the document to determine which member(s) are most impacted. If stack members are chronically unstable, reseat the stack hardware and ensure cable thumb screws are hand tightened. Most stack-related instability stems from misalignment of the physical stack media - the stack cables and/or stack adapters. Chronic instability can lead to a situation where the stack splits and merges. If communication between the active/standby and members is interrupted, reloads occur. Troubleshoot Stackwise-Related Operational Problems Bundle mode requires manual intervention to resolve version license mismatch errors. Bundle mode does not support auto-upgrade.

Note: The auto-upgrade feature is only available in Install mode.

End with CNTL/Z.Ĭ9300-Stack(config)# software auto-upgrade enable It is implemented with this command: C9300-Stack# config tĮnter configuration commands, one per line. The auto-upgrade feature can be leveraged to resolve these conflict problems when you add a new switch.

Operational mode (Install vs Bundle) must match.

Connect new member(s) while powered-down to avoid a stack-merge. Importantly, never connect a powered-on switch into a powered-on stack. Several factors must be considered when you implement a new stack or add a member to an established stack.

Switch numbers do not reflect the physical orientation of the switches within the stack.

Switch number conflicts are resolved by the active.

Switch numbers remain persistent after reload and if a member is removed.

Switch priority is manually configured- the change takes effect after reload.With active elected and all members discovered, the standby is elected with the same criteria – next highest priority or next lowest MAC. Stack Discover Protocol (SDP) is used by the switches connected to the stack topology for neighbor discover and role election. After bootup, and before the switch software loads completely, there is a 120-second election window where members are discovered, and the active and standby roles are determined.Īctive election is determined by the highest priority and then lowest MAC address.

The ring can operate at half or full capacity. The stack ring provides interconnectivity between the active/standby switches and the member switches. Stackwise OperationĬonnect two or more (up to eight) switches with the relevant Stackwise stack kit to form a data stack.

This section explains how stack ring instability can induce reloads and other problems, and how to validate the stack ring and troubleshoot related issues. Operational issues in established stacks often relate to silent reloads of one or all member devices, with stack merge a common reload reason. It simplifies management and allows for greater resilience and scalability. The stack architecture expands the switches’ form factor, throughput, port density, and redundancy and provides a single control and management plane. StackWise architecture allows a stack of up to eight switches in a ring topology to achieve a high density of stack bandwidth. This article is applicable to Catalyst 9200/9200L, 9300/9300L and 9300X switches. C9300/9300X PID stack kits only require the cable. These PIDs support Stackwise:Ĭ9200/C9200L and C9300L PID stack kits contain a stack adapter which seats into the chassis and a cable which connects to the adaptor. If your network is live, ensure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment.

This section specifies the Product IDs (PIDs) and associated components relevant to Stackwise on the Catalyst 9000 family. This document describes how to troubleshoot common failure scenarios in Stackwise deployments of Catalyst 9200/9200L and 9300/9300L.
