SNMP: Monitoring External (WAN) Traffic Only.
Posted on 2008-11-17
Hello - a few questions for our office:
We are monitoring In/Out Bits for Total Bandwidth on a handful of switches using Cacti.
Is it possible to graph traffic that only goes across the internet and is not transmitted from one port to another.
My problem stems from 2 users transferring data between 2 local switch ports. For billing purposes, we only need to know how much traffic is transferred in/out the wan, not internal traffic caused by sharing files.
#2 - Will setting up VLANs solve this issue? Does monitoring a VLAN include LAN traffic?
#3 - Am I right to say that if a user transfers large files over the local LAN from one office to another it will slow down the overall performance of the network and WAN (internet) speed?
