If I have a router with sub-interfaces and I generate a report on bandwidth for the physical interface itself, will the report give me the total amount of bandwidth utilized for itself and all sub-interfaces or just itself? I know if I generate a chart on interface bandwidth for a router, the chart will show me bandwidth and the breakdown of all interfaces on the router including sub-interfaces. For example, if I have gi0/1 with sub-interfaces gi0/1.1 and gi0/1/2, the chart will show me 3 lines however, this doesn't answer my question. Let's say for a day I transmit this amount of bandwidth:
gi0/1 (physical interface): 10 Mbps
gi0/1.1 (sub-interface): 2 Mbps
gi0/1.2 (sub-interface): 3 Mbps
Does that 10 Mbps from gi0/1 include the 5 Mbps (2 + 3 Mbps from both gi0/1.1 and gi0/1.2)?
Anyone with insight about this?
I was informed that this depends on Cisco.
