When polling interface statistics with Getif and mapping the VLAN stats to the interface stats, I do not see correlation between actual traffic created and verified on VLAN IfInOctets or IfOutOctets. Polling the interfaces themselves is accurate, but the VLAN information does not seem to be. Is this as designed?
How do you mean? Typically, VLAN interfaces do not contain an aggregate count of port counters since they are only counting packets that are routed via those interfaces. Intra-VLAN, and layer 3 hardware switched frames will not be counted.
Exactly what I thought. I need an accurate count of all traffic carried by an interface, and it was suggested that L3 VLANs could be used for separation of organization, regardless of where the physical ports were. Thank you for your response.
