lots of arp broadcasts on my network

I see lots arp traffic when looking at the network through a sniffer.

When I look at my switch I see input drops but I can not catch them incrementing at the moment.

Looking at the cpu I see this for my input traffic.

sh process cpu | i ^PID|Input
   8       66776    144034        463  0.39%  0.27%  0.30%   0 ARP Input       
  52        1804    109764         16  0.00%  0.00%  0.00%   0 Net Input       
146      121096    799915        151  0.63%  0.66%  0.63%   0 IP Input        
204           0         1          0  0.00%  0.00%  0.00%   0 Probe Input

Re: lots of arp broadcasts on my network

Hi Mark

Looking at the output:

  8       66776    144034        463  0.39%  0.27%  0.30%   0 ARP Input  

ARP process just takes 0.3 % of the CPU cycle, which is pretty normal.. Is there any issue on the network ? Can you please let us know your network on a high level ? can you paste us the full output of show proc incase you have issues with this switch ?

hope this helps.. all the best

Raj
