Hi AshvinO,
unfortunately this dosn't helo. EX4200 is connected to MX10. I try this:
EX4200:
ether-options { no-flow-control; link-mode full-duplex; speed { 10g; } }
MX10
[edit interfaces xe-1/2/0] root@mx10# show description citynet; vlan-tagging; link-mode full-duplex; gigether-options { no-flow-control; }
Traffic is 1.64Gbit ( TX ) and 780 ( TX )
