This tool does not verify whether SIPs or SPAs within a system are compatible, but it does provide the minimum Cisco IOS requirements for individual hardware modules or components. Note Access to this tool is limited to users with Cisco.com login accounts. To access Software Advisor, click Login at Cisco.com, type "Software Advisor" in the SEARCH box, and click GO. Click the link for the Software Advisor tool. Choose a product family or enter a specific product number to search for the minimum supported software release needed for your hardware. Bandwidth Oversubscription Oversubscribing the bandwidth limit recommendations of a router can result in decreased or degraded performance. For this reason, it is important to determine the amount of bandwidth used by the SPAs on the router and verify that the total bandwidth used by all SPAs does not exceed the recommended bandwidth limit of the router. Table 3-2 provides information about the bandwidth for each port (per-port bandwidth) on a SPA and the cumulative bandwidth (total bandwidth) for all ports available on the SPA.
