Quick Overview Of The Supervisor Engine Upgrade Processīefore we dive into the upgrade process, let’s take a quick look at the steps to be followed. Note: The process we are about to describe was performed on a live 4507R+E with two Supervisor Engines 7L-E, on a network of 120+ users and 11 servers connected to our 4507R+E via dual 10Gbps fiber optic links (one 10Gbps link on each Supervisor Engine). On the other hand, the Cisco Catalyst 4507R and 4510R series are capable of accepting up to two Supervisor Engines (hence the ‘ R’ – Redundancy), therefore in case of a 4507R/ 4510R with two Supervisor Engines installed, IOS upgrades can be performed with guaranteed Zero-Service-Interruption. For the Cisco Catalyst 45 series, which can only accept a single Supervisor Engine, this means network service interruption is unavoidable as the single Supervisor Engine must reboot. Who wouldn’t be? This is, after all, the network backbone switch and when it comes to large campus, Enterprise networks or networks that operate around the clock, downtime is not an option.Īt this point, we should note that when upgrading a Supervisor Engine the engine must be reloaded (rebooted) in order for the system to load the new IOS image. This is perhaps one of the most frequently asked question that troubles engineers, administrators and IT Managers who have not dealt with the Supervisor Engine upgrade process before. Installation of a Cisco Catalyst 4507R-E Layer 3 SwitchĪre Network Services Affected During Or After The Catalyst Supervisor Engine(s) Upgrade?.Cisco 4507R+E Layer 3 Installation: Redundant WS-X45-SUP7L-E Supervisor Engines & WS-X4648-RJ45V+E Line Card.Note: Information on installing the Cisco 4507R-E/4507R+E Catalyst Switch, Supervisor Engines, Line cards and power supplies can be found in our following articles which, combined, contain over 30 pictures of all switch components, including the passive backplane, fantray and more: This contract not only makes you eligible for all software upgrades for the duration of your contract, but also binds Cisco in delivering Top-Class support for your covered device(s). To be eligible to download an IOS image from Cisco’s website, one must have a valid contract support with Cisco Systems. Unlike other vendor operating systems, it is always advisable to keep your Cisco Catalyst operating system up to date by fitting it with the latest IOS image. Every packet that enters or exits your switch passes through the Supervisor Engine and, naturally, the Cisco IOS is the software that brings this beast to life.Ĭisco makes an enormous effort to bring new features to its products through new versions of its popular IOS software, especially for the enterprise-class series switches such as the 45 Catalyst switches. It is the equivalent of an engine in a car. The Supervisor Engine is the heart of the Cisco Catalyst 45 series switches.
