Hi!

I'm facing a strange limitation on ex-4200 virtual-chassis: 
vcp-interfaces are configured with mtu 1500: 

s...@vsw02# run show interfaces vcp-0                   
Physical interface: vcp-0, Enabled, Physical link is Up
  Type: 105, Link-level type: 70, MTU: 1514, Speed: 32000mbps

and not reconfigureable to use jumbo frames: 

s...@vsw02# show | compare 
[edit interfaces]
+   vcp-0 {
+       mtu 9216;
+   }
s...@vsw02# commit check 
[edit interfaces]
  'vcp-0'
     Interface is not user configurable
error: configuration check-out failed

As a result, hosts within the same vlan but connected to different
VC members is not able to reach each other with big packets :( 

Are there any way to overcome this limitation ?

In theory, there is no difference between theory and practice. 
But, in practice, there is.
