2. Use the ping command from a device on one subnet to an address on another subnet
to determine whether packets were transmitted correctly on the subinterface VLANs:
user@switch> ping ip-address
PING 1.1.1.1 (1.1.1.1): 56 data bytes
64 bytes from 1.1.1.1: icmp_seq=0 ttl=64 time=0.157 ms
64 bytes from 1.1.1.1: icmp_seq=1 ttl=64 time=0.238 ms
64 bytes from 1.1.1.1: icmp_seq=2 ttl=64 time=0.255 ms
64 bytes from 1.1.1.1: icmp_seq=3 ttl=64 time=0.128 ms
--- 1.1.1.1 ping statistics ---
4 packets transmitted, 4 packets received, 0% packet loss
Meaning The output confirms that the subinterfaces are created and the links are up.

Verifying Unicast RPF Status
Purpose Verify that unicast reverse-path forwarding (RPF) is enabled and is working on the
interface.
Action Use one of the show interfaces interface-name commands with either the extensive or
detail options to verify that unicast RPF is enabled and working on the switch. The
following example displays output from the show interfaces ge- extensive command.
