Ping Test. This is a test of the path between the switch and another device
on the same or another IP network that can respond to IP packets (ICMP Echo
Requests).
Link Test. This is a test of the connection between the switch and a desig­

link test, IEEE 802.2 test packets are sent to the designated network device
in the same VLAN or broadcast domain. The remote device must be able to
respond with an 802.2 Test Response Packet.
