Background Information Brief Description of SPAN If your network is live, make sure 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. Although this document is updated to reflect changes to SPAN, refer to your switch platform documentation release notes for the latest developments on the SPAN feature. On the Catalyst 2900XL/3500XL Series Switches, Cisco IOS ® Software Release 12.0(5)XU is used. This information in this document uses CatOS 5.5 as a reference for the Catalyst 4500/4000, 5500/5000, and 6500/6000 Series Switches. There are no specific requirements for this document. Supervisor 720 with PFC3A that has hardware version 3.2 or later and running Cisco IOS Software Release 12.2(18)SXE or laterĬatalyst 4500/4000 Series (includes 4912G)
Yes Supervisor 2T with PFC4, Supervisor 720 with PFC3B or PFC3BXL running Cisco IOS Software Release 12.2(18)SXE or later. Prerequisites Catalyst Switches That Support SPAN, RSPAN, and ERSPAN Catalyst Switches What are the different features available (especially multiple, simultaneous SPAN sessions), and what software level is necessary in order to run them? What is SPAN and how do you configure it? This document answers the most common questions about SPAN, such as: This document is not intended to be an alternate configuration guide for the SPAN feature. However, the latest releases of the Catalyst OS (CatOS) introduced great enhancements and many new possibilities that are now available to the user. Previously, SPAN was a relatively basic feature on the Cisco Catalyst Series switches. The network analyzer can be a Cisco SwitchProbe device or other Remote Monitoring (RMON) probe. The SPAN feature, which is sometimes called port mirroring or port monitoring, selects network traffic for analysis by a network analyzer. This document describes the recent features of the Switched Port Analyzer (SPAN) that have been implemented.
