Tested interfaces
UTP：Auto Nego (10/100TX), Auto Nego (10/100/1000T), 10BASE-T fixed, 100BASE-TX fixed
Optical：Auto Nego (1000BASE-X),1000BASE-X fixedComments on the results
Link-up and communication
All the models have achieved the transmission speed and the half duplex/full duplex communication expectations.
To use 10 Mbps and 100 Mbps fixed connections, use a crossover cable.

Link aggregation
In most cases, a switchover has been completed within one second of a communication interruption.
However, the communication interruption time will become longer if a line fault is detected when 1000BASE-T is used.
This is due to the physical layer standard (IEEE 802.1ab) for link-down detection.
Reference: Line fault detection time (ms) specified in IEEE 802.1ab
Clock master: 750±10, clock slave: 350±5

Comment(Note)

Switchover
within one second
possible
No impact oncommunication

Note: If a stackable device (master) failure occurs in a LACP configuration, the Catalyst changes theaddress information notified in the LACPDU from the MAC address of the stackable switch (master) tothat of the stackable switch (slave).
On the other hand, the AX continues to recognize the MAC address of the master switch as the partner
device's address until it fails to receive the LACPDU three times. This causes a longer communicationinterruption.
