# Ping Switch A and Switch B on the host, and ping Switch A and the host on Switch B to verify that they
are connected.
NOTE:
When you ping a link-local address, use the -i parameter to specify an interface for the link-local
address.
[SwitchB] ping ipv6 -c 1 3001::1
Ping6(56 data bytes) 3001::2 --> 3001::1, press CTRL_C to break
56 bytes from 3001::1, icmp_seq=0 hlim=64 time=4.404 ms
--- Ping6 statistics for 3001::1 ---
1 packet(s) transmitted, 1 packet(s) received, 0.0% packet loss

[SwitchB] ping ipv6 -c 1 2001::15B:E0EA:3524:E791
Ping6(56 data bytes) 3001::2 --> 2001::15B:E0EA:3524:E791, press CTRL_C to break
56 bytes from 2001::15B:E0EA:3524:E791, icmp_seq=0 hlim=64 time=5.404 ms
--- Ping6 statistics for 2001::15B:E0EA:3524:E791 ---

The output shows that Switch B can ping Switch A and the host. The host can also ping Switch B and
Switch A.
Troubleshooting IPv6 basics configuration
Symptom
An IPv6 address cannot be pinged.
Solution
1. Use the display ipv6 interface command in any view to verify that the IPv6 address of the output
interface is correct and the interface is up.
2. Use the debugging ipv6 packet command in user view to enable the debugging for IPv6 packets
to locate the fault.
