Hi Experts, i am planning deployment of QFX 3000-M. Found few excellent online support , even for control plan (EX 4200 24T switches) configuration file is available just copy, paste and control plane is ready. I found configuration file a bit hard to understand (specially due to inclusion of groups etc). What i have decided to follow the control plan cabling scheme as per Juniper recommendation but change control plane configuration. I will establish a virtual chassis consists of two EX 4200,
ge-0/0/0 and ge-1/0/0 connected to node-0 and configured as ae0 (mtu 9216 and vlan-id xxx dot1q-tunneling enabled)
ge-0/0/1 and ge-1/0/1 connected to node-1 and configured as ae1 (mtu 9216 and vlan-id xxx dot1q-tunneling enabled)
and so on for all nodes
ge-0/0/16 and ge-1/0/16 connected to IC-1 and configured as ae7 (mtu 9216 and vlan-id xxx dot1q-tunneling enabled)
ge-0/0/17 and ge-1/0/17 connected to IC-2 and configured as ae8 (mtu 9216 and vlan-id xxx dot1q-tunneling enabled)
ge-0/0/20 , ge-0/0/21, ge-1/0/20, ge-1/0/21 connected to DG0 and configured as ae9 (mtu 9216 and vlan-id xxx dot1q-tunneling enabled, LACP active)
ge-0/0/22 , ge-0/0/23, ge-1/0/22, ge-1/0/23 connected to DG1 and configured as ae10 (mtu 9216 and vlan-id xxx dot1q-tunneling enabled, LACP active)
Now you see deviation from Juniper configuration for control plane. But i think it is easy to understand the configuration in this way, manage and trouble shoot control plane. Need comments from experts , what adverse effects may this deviation cause on operation of QFX-3000M in production network
