Link; Cdp/Lldp - Pockethernet Manual

Link

This test determines if an ethernet link can be established, what the highest
achievable speed is. The result is shown in the summary line: 10 / 100 / 1000
Mbit, Full Duplex / Half Duplex, MDI / MDI-X.
On gigabit links, additional information is shown: The delay skew of each pair
(maximum allowed per IEEE specification is 45ns) and the polarity of each
wire pair, which helps detecting any wiring errors.

CDP/LLDP

When activated, Pockethernet waits for up to 65 seconds after link
establishment to receive CDP or LLDP packages.
These diagnostic packages contain information about the connected switch
or router, like the physical port ID Pockethernet is connected to, the system
name or management IP address. Information fields, called TLVs of the
received packet are listed in the details section of this measurement.
A link test will always be selected in order to test the CDP/LLDP settings. The
app will auto-select it once you select the CDP/LLDP test.
