Не совсем к раритетам. Ты же не будешь называть 3560,3750 + low end ME switches раритетом.
http://www.cisco.com/en/US/products/hw/swi...0801b0971.shtmlQ. For which fixed configuration and stackable Cisco Catalyst Switch product families can I obtain a "no additional cost" Cisco IOS® Software update?
A. Cisco offers ongoing Cisco IOS Software updates for the following fixed configuration and stackable Cisco Catalyst Switch product families at no additional cost. For the life of the product, updates within the Cisco IOS Software package purchased (for example, LAN Base, IP Base, IP Services, and so on) will be made available to customers.
• Cisco Catalyst Express 500 Series Switches
• Cisco Catalyst 2900 XL Series Switches
• Cisco Catalyst 2940 Series Switches
• Cisco Catalyst 2948G-GE-TX Series Switch
• Cisco Catalyst 2950 Series Switches
• Cisco Catalyst 2950 LRE Series Switches
• Cisco Catalyst 2955 Series Switches
• Cisco Catalyst 2960 Series Switches
• Cisco Catalyst 2970 Series Switches
• Cisco Catalyst 3500 XL Series Switches
• Cisco Catalyst 3550 Series Switches
• Cisco Catalyst 3560 Series Switches
• Cisco Catalyst 3750 Series Switches
• Cisco ME 2400 Series Ethernet Access Switches
• Cisco ME 3400 Series Ethernet Access Switches
Note: Upgrades are different from updates. For example, an upgrade from the IP Base package to IP Services package provides significant new function; therefore, this upgrade requires the purchase of a software license upgrade. Updates are incremental software features and bug fixes that are released within a Cisco IOS Software package for which you own a license.
Взять update от ADV IP SVC вместо IP Base может помешать разве только что совесть .
