Re: [Packetfence-users] common problem we've seen

[Matt A. <md...@un...>]

I think judging by the fact that I have 2051 rows of data in my node table,
but have 15234 entries in the locationlog, that the system is not removing
them correctly. 

What's the corresponding log entry that should appear?

Thanks

Matt

Hi Matt,

normally, PacketFence uses the locationlog entries to remove the  
computers security entry on the previous switchport. In the example  
below, when the user connects in step (2), the mac security entry  
created in the residence in step (1) should be removed.

In you environment, does this systematically not happen ?
