DAI Question

Daniel333

All,

Been a couple years since I had to think of CCNA:Sec stuff so I am pretty rusty.

What are all the fields here from the output of a DAI alert?

SwitchB#

 1w2d: %SW_DAI-4-INVALID_ARP: 9 Invalid ARPs (Req) on Gi3/31, vlan 
100.([0002.0002.0002/170.1.1.2/0001.0001.0001/170.1.1.1/02:30:24 UTC Fri Feb 4 2005])

0002.0002.0002 = source mac?
170.1.1.2 = source Ip?

0001.0001.0001 = dest mac?
170.1.1.1 = desk IP?

I have been studying the CCNA Security (640-553) on and off for the last four weeks, and there was no mention of Dynamic ARP Inspection in the CCNA Security topic, so you might want to check out this article, Catalyst 4500 Series Switch Cisco IOS Software Configuration Guide, 12.2(31)SGA - Configuring Dynamic ARP Inspection  [Cisco Catalyst 4500 Series Switches] - Cisco Systems.
