[admin@atrinnet.net]

Hi Dears I used 2 switch 3850 A and B and dot1q tunneling for trunking

My network transit operator assign me vlan 100 i used dot1q and Q in Q my latency is ok

on vlan 1000 and 2000 on servers file transfer is slow icmp is ok i donnot have any policy operator is too donot have any shaping

on the dot1q tunnel by default have shaping ??? or any policy ?

Hello admin@atrinnet.net,

The default behavior for dot1Q tunneling on your C3850 switches does not inherently include shaping or any specific policies.

Do you check if you have any other points of congestion within your network that could be impacting the performance between the servers on VLANs 1000 and 2000 ?

Is it possible to monitor traffic on that dot1q link? See if you have fragmentation etc...
