Cisco Tech Talk: Change of Authorization on Catalyst 1300 Switches – Part 1
Change of Authorization (CoA) allows network administrators to modify AAA session properties post-authentication using RFC-based RADIUS extensions on Cisco Catalyst 1300 switches.
MAIN POINTS FROM TRANSCRIPT
- CoA enables post-authentication changes to AAA sessions using RADIUS protocol extensions.
- Cisco ISE acts as a dynamic authorization client to test CoA on Catalyst 1300 switches.
- Effective CoA communication requires direct connectivity between the switch and Cisco ISE, but not necessarily on the same subnet.
TAKEAWAYS
- CoA functionality is supported from version 4.1.0.3 on Catalyst 1300 switches.
- RFC 3575 and 5176 provide the framework for CoA operations within the RADIUS protocol.
- Dynamic authorization requires careful configuration of network connectivity between the ISE and the switch.
