[j-nsp] EX-4200 two members virtual chassis problem

[laith zuraiqi]

Dears,
 
I
have two ex-4200-24 f running 11.4r8.5 software, connected through two VCP
ports, it was connected to mx router by trunk port and the uplink connected to
member 0.
The
customers connected to member 0(master) working fine , but when I add a
customer to member 0 I cannot access to the MX-Router .I toggled the mastership
between the two members all my services go down .
 
Any
suggestions
