The ToR Cisco Nexus 9300 platform switches and Cisco Nexus 3100 Series switches are the standalone switches with single supervisors. Performing Standard ISSU on Top-of-Rack (ToR) Switches with a Single Supervisor Performing enhanced ISSU on Top-of-Rack (ToR) switches with a single supervisor Performing standard ISSU on End-of-Row (EoR) switches with two supervisors Performing standard ISSU on Top-of-Rack (ToR) switches with a single supervisor
The following ISSU scenarios are supported:
The guest shell is disabled during the ISSU process and it is later reactivated after the upgrade.Įnhanced ISSUs are supported for some Cisco Nexus 9000 Series switches and the Cisco Nexus 3164Q, 31128PQ, 3132Q-V, 31108PC-V, Using the nondisruptive option helps ensure a nondisruptive upgrade. Therefore, ISSU needs to be enabled using the command-line interface (CLI), asĭescribed in the configuration section of this document.

(See the Cisco NX-OS Software Upgrade Guidelines for a complete list of supported platforms.) You can perform an ISSU, also known as a nondisruptive ISSU reduces or eliminates the downtime typically caused by software upgrades. On EPLD images and the upgrade process, see the Cisco Nexus 9000 Series FPGA/EPLD Upgrade Release Notes.Īn in-service software upgrade (ISSU) allows you to upgrade the device software while the switch continues to forward traffic. The EPLD image upgrades are independent from the Cisco NX-OS software upgrades. For more information on SMUs, see the Cisco Nexus 9000 Series NX-OS System Management Configuration Guide.Ĭisco also provides electronic programmable logic device (EPLD) image upgrades to enhance hardware functionality or to resolve SMU package files are available for downloadįrom and generally include the ID number of the resolved defect in the filename (for example, n9000-dk9.3.1. They are created to respond to immediate issues and do not include new features. The Cisco Nexus 9000 Series switches and the Cisco Nexus 3132C-Z, 3132Q-V, 3164Q, 3232C, 3264C-E, 3264Q, 31108PC-V, 31108TC-V,ģ1128PQ, and 34180YC switches support disruptive software upgrades and downgrades by default.Īnother type of binary file is the software maintenance upgrade (SMU) package file.
