SYS4 error

2006 Jan 20 07:02:11 PST -08:00 %SYS-4-P2_WARN: 8/Filtering Ethernet MAC address

of value zero from agent host table interface

I started getting these all of a sudden everyday. Looked up the explanation but wasn't much help. How can I track this down? Thanks in advance.

Re: SYS4 error

Hi,

Here's another link that describes it:

You'll have to use a sniffer to try to identify the source. Although the source mac is all zeros, there may be upper level protocol information that may help identify the source of these packets.

HTH,
