The dropped graph is actually displaying the ifOutDiscard values. As you are seeing drops on the RX line they wouldn't be ifOutDiscard packets but ifInDiscard (if anything) count.
Drops are generally thought of ifOutDiscard because this is where it normally happens on network devices such as routers. It usually means you are driving the interface too fast. It is generally the more important of the two to monitor. Incoming packets being dropped usually mean something is wrong with the setup. An obvious example is incoming tagged 802.1q packets for a VLAN you don't have (or don't permit). The proper fix is to go downstream one device and tweak the VLANs permitted to be sent. You pump appletalk into an ip-only device and you might see this too. - Craig -- Craig Small VK2XLZ http://enc.com.au/ csmall at : enc.com.au Debian GNU/Linux http://www.debian.org/ csmall at : debian.org GPG fingerprint: 5D2F B320 B825 D939 04D2 0519 3938 F96B DF50 FEA5 ------------------------------------------------------------------------------ Don't let slow site performance ruin your business.
