lets say i have a switch port
GigabitEthernet1/0/1
switchport access vlan 10
switchport mode access
interface Vlan10
description Vlan10
ip address 10.0.0.1 255.255.255.0
"show interface summary"
1. what traffic is counted on the interface vs the vlan
2. if the traffic is coming from a device (other switch etc.) which also has set its interface as "mode access"
3. if the port is "mode trunk"
bit confused here

Hello,
the traffic counted on the physical interface is ALL traffic that comes from whatever is connected to this interface.
The traffic counted on the SVI (Vlan 10 interface) is the traffic that is going to other SVIs (that is, layer 3 traffic destined for another subnet or external destination). Any inter-Vlan traffic never passes through the SVI.

thank you
my confusion came probably because i had ip routing enabled on the switch and saw little spikes in the vlan traffic
still not sure what they are as although ip routing was enabled i havent used it
some route announcements maybe?
any way on my router i can more clearly see whats going on
