I have 3 vlan on 4503 switch .
When i am trying to copy data within vlan say vlan2 to vlan2 its very fast but when i am doing intervlan vlan2 to vlan3 copying its very very slow.
Port speed ,cables are all swapped and changed theer is no STP loop no high CPU.
All the devices are connected to 1 switch no other switch is involved in between,no access-list.
I have tried hard to find what could be the problem but was not able to.
