Hi,
our switching guys reported that their Cisco Nexus switches running NX-OS log
that their can't reach the tacacs servers. This is what the troubleshooting
brought up:

According to Cisco the accounting responses from Radiator (version 4.11 with
patches revision 1.1530) contain errors:
Accounting Statistics
failed transactions: 1865
successful transactions: 0
requests sent: 1865
requests timed out: 4
responses with no matching requests: 0
responses not processed: 0
responses containing errors: 1861
Did someone else notice these problems? Authentication works without any
problems.
