Refer to the exhibit. AAA server 10.1.1.1 is configured with the default authentication and accounting settings, but the switch cannot communicate with the server.
Which action resolves this issue?
The issue specified in the question pertains to the switch's inability to communicate with the AAA server, 10.1.1.1, which is configured with the default authentication and accounting settings. Typically, RADIUS servers use UDP port 1812 for authentication and UDP port 1813 for accounting. Ensuring that the authentication port on the switch matches the default port on the AAA server is crucial for proper communication. Hence, matching the authentication port resolves the issue.
The port values of 1812 for authentication and 1813 for accounting are RADIUS standard ports defined by the Internet Engineering Task Force (IETF) in RFCs 2865 and 2866. However, by default, many access servers use ports 1645 for authentication requests and 1646 for accounting requests.
Radius authentication port is 1812. Hence authentication needs to be matched.
Ref: Solved: Which port numbers are used for RADIUS accounting and RADIUS authentication? - Cisco Community Post by Peter Paluch “Hi, On all recent RADIUS server implementations, UDP/1812 is the authentication and authorization port, and UDP/1813 is the accounting port. …” A. Correct the timeout value. Wrong answer. B. Match the authentication port. Correct answer. C. Correct the shared secret. Wrong answer. D. Match the accounting port. Wrong answer.
B is correct RADIUS uses those ports: UDP port 1812 for authentication UDP port 1813 for accounting
The given answer is correct
The given answer is correct
Should be C .
No its B as "default" authentication RADIUS port is 1812
