ARP Traffic
-
How much ARP traffic is too much. In our environment we have about 140 devices on the same subnet. It seems as though every machine keeps track of where every other machine is. Sometimes even the router (meraki mx84) is sending out those requests 2 or 3 times per minute per device.
The switches are a mix of SG200, SG300, SF200, SF300 switches. Most of which just have never been configured other than what's default.

How many devices? I haven't managed an environment where ARP was ever a problem. Some of the best practices, like creating a vlan for VoIP (QoS) reduces it quite a bit.
-
there is a vlan for voip (all on a separate switch).
I'm not sure it is a problem - I guess I was just curious to know how much seems to be right. There are about 100 arp packets per second.

Seems about right. I remember getting a Fluke LANmeter about 15 years ago and seeing all the traffic on our network in real time. I was amazed at all the broadcast traffic. Then I went in to the SNMP view on our switches. Even on the 100Mb/s switches percentage wise, the traffic wasn't measurable.

Yeah. Usually the ARP traffic is just not an issue, unless there are other underlying issues in the network.

Very few people have. ARP traffic is very small and part of the Ethernet layer.

Seems like a reasonable amount of traffic. That's really just background noise on a network.

Especially when SNMP sometimes queries 2-3 times a second.

I agree, it seems reasonable.

Sounds good, thanks for the help.
