#### Meaning

Table 28 lists the show radius statistics command output fields.

| Note: All descriptions apply to the primary, secondary, and tertiary RADIUS authentication and accounting servers.

Table 28: show radius statistics Output Fields

Field Name | Field Description
--- | ---
UDP Port | Number of the UDP port of a RADIUS server
Round Trip Time | Hundreds of seconds from request to response
Access Requests | Number of access requests sent to server
Rollover Requests | Number of requests coming into server as a result of the previous server timing out
Retransmissions | Number of retransmissions
Access Accepts | Number of Access-Accepts received from the server
Access Rejects | Number of Access-Rejects received from the server
Access Challenges | Number of access challenges received from the server
Malformed Responses | Number of responses with attributes having an invalid length or unexpected attributes (such as two attributes when the response is required to have at most one)
Bad Authenticators | Number of responses in which the authenticator is incorrect for the matching request. This can occur if the RADIUS secret for the client and server does not match.
Requests Pending | Number of requests waiting for a response
Request Timeouts | Number of requests that timed out
Unknown Responses | Number of unknown responses. The RADIUS response type in the header is invalid or unsupported.
Packets Dropped | Number of packets dropped either because they are too short or the E-series router receives a response for which there is no corresponding request. For example, if the router sends a request and the request times out, the router removes the request from the list and sends a new request. If the server is slow and sends a response to the first request after the router removes the request, the packet is dropped.
Requests | Total number of accounting requests sent, which is the combined total of Start Requests, Interim Requests, Stop Requests, and Reject Requests
Start Requests | Number of accounting start requests sent; includes Acct-On, Acct-Start, Acct-Link-State, and Acct-Tunnel-Start requests
Interim Requests | Number of interim accounting requests
Stop Requests | Number of accounting stop requests sent; includes Acct-Off, Acct-Stop, Acct-Link-Stop, and Acct-Tunnel-Stop requests
Reject Requests | Number of accounting reject requests sent; includes Acct-Link-Reject and Acct-Tunnel-Reject requests
Responses | Number of accounting responses received from the server
Start Responses | Number of accounting start responses received; includes Acct-On, Acct-Start, Acct-Link-Start, and Acct-Tunnel-Start responses
Interim Responses | Number of interim accounting responses
Stop Responses | Number of accounting stop responses received; includes Acct-Off, Acct-Stop, Acct-Link-Stop, and Acct-Tunnel-Stop responses
Reject Responses | Number of accounting reject responses received; includes Acct-Link-Reject and Acct-Tunnel-Reject responses
