Step1 need to follow
Before configuring the ae0 need delete the ethernet switch under the interface
set chassis aggregated-devices ethernet device-count 5
set interfaces ae0 aggregated-ether-options lacp active
set interfaces ge-0/0/0 ether-options 802.3ad ae0 >>>>>Link switch 1
for High Availability
set interfaces ge-0/0/1 ether-options 802.3ad ae0 >>>>>Link switch 2 High

How enable Juniper
stacking
In Juniper Ex3300 is using hardware stacking so not required
to put the CLI commands for doing the
stacking Port number xe-0/0/2 and xe-0/0/3 are already in stacked mode (only
required to doing the cabling part)
For more information on Ex3300 stacking
Stacking in 4550
juniper switch
We
required choosing the link first and enabling the stacking on them.
Request
virtual-chassis vc-port set pic-slot 0 port
xe-0/0/31 ß and restart /switch1
Request
