Overview
This section provides an introduction about transceiver firmware upgrades with NX-OS, and informs about how this upgrade improves performance, addresses issues, ensures compliance, and supports efficient bulk updates for supported models.
Transceiver firmware upgrades are the software upgrades that
-
enhance transceiver performance and resolve known issues
-
are bundled with NX-OS releases,
-
and apply only to supported transceiver models.
The transceiver firmware upgrade feature provides network administrators with the ability to
-
update transceiver firmware to address bugs and security vulnerabilities
-
enhance transceiver performance through firmware optimizations
-
maintain compliance with latest industry standards, and
-
perform bulk firmware updates across multiple interfaces.
One of the ways in which the transceiver firmware upgrade can be performed is by using the NX-OS command framework. This requires careful procedural adherence to avoid disruption and maintain network stability. For more information, see Firmware upgrade using NX-OS commands.
You can upgrade transceiver firmware faster by processing multiple downloads simultaneously. The process involves careful grouping of ports for parallel operations, but ports on the same Inter-Integrated Circuit (I2C) line are updated sequentially. For more information, see Parallel firmware download.
