Security Log Output question

[RichTJ99]

Hi,

A few questions about the security logs:

What does this mean (it goes on for pages & pages):

Code:

freenas.local kernel log messages:
> arp: 192.168.168.155 moved from dc:9b:9c:ef:1d:dc to 00:0c:29:c9:36:db on epair1b
> arp: 192.168.168.155 moved from 00:0c:29:c9:36:db to dc:9b:9c:ef:1d:dc on epair2b

-- End of security output --

Code:

freenas.local kernel log messages:
> arp: 08:00:27:72:90:65 attempts to modify permanent entry for 192.168.168.113 on em0
-- End of security output --

Code:

freenas.local kernel log messages:

Are these normal things I should ignore?

Thanks,
Rich
