Acct-Flag in TACACS+ Accounting

Real quick ...

Can anyone tell me the significance of an Acct-Flag entry "NAS Port re-used" might have in TACACS+ accounting?

Thank you. Tom

Re: Acct-Flag in TACACS+ Accounting

You'll usually see this on ACS when the NAS sends out an accounting start record for a userid, but ACS has already received a start record and still thinks that user is logged on. In other words, the NAS sent two start records without a stop record in between them.

This quite often occurs when a user logs into a router, then also goes into enable mode, and accounting is turned on. The router will send a start for the initial login, and another start record for going into enable mode, but there's no stop record in there cause the user never logged out. Nothing to worry about usually.
