After configuring Layer 3 subinterfaces, verify they are set up properly and transmitting
data.
Use the
show interfaces
1.
subinterfaces and the links are up:
user@switch> show interfaces interface-name terse
Interface
ge-0/0/0
ge-0/0/0.0
ge-0/0/0.1
ge-0/0/0.2
ge-0/0/0.3
ge-0/0/0.4
ge-0/0/0.32767
Use the
command from a device on one subnet to an address on another subnet
ping
2.
to determine if packets were transmitted correctly on the subinterface VLANs:
user@switch> ping ip-address
