sequence of these messages, terminating only when the maximum timeout
has been reached, may indicate this problem with the target device.
The same link-local address may be used by different interfaces/nodes in
different zones (RFC 4007). Therefore, when specifying a link-local address,
include zone-id information indicating the VLAN identifier after the % delimiter.
For example, FE80::7272%1 identifies VLAN 1 as the interface from which the
trace route is sent.
Web Interface
To trace the route to another device on the network:
1.
Click IP, General, Trace Route.
2.
Specify the target device.
3.
Click Apply.

Address Resolution Protocol
The switch uses Address Resolution Protocol (ARP) to forward traffic from one hop
to the next. ARP is used to map an IP address to a physical layer (i.e., MAC) address.
When an IP frame is received by this switch (or any standards-based switch/router),
it first looks up the MAC address corresponding to the destination IP address in the
ARP cache. If the address is found, the switch writes the MAC address into the
appropriate field in the frame header, and forwards the frame on to the next hop. IP
traffic passes along the path to its final destination in this way, with each routing
device mapping the destination IP address to the MAC address of the next hop
toward the recipient, until the packet is delivered to the final destination.
