automatically disabled and the speed/duplex mode is
automatically set to 100Mbps full-duplex for Ports 1-48 and
1000Mbps full-duplex for Ports 49-50.
❑ If you create a VLAN with ports that are port of a port trunk, the
other port members of the port trunk are automatically added to
the VLAN.
❑ When cabling a trunk, the order of the connections should be
maintained on both nodes. The lowest numbered port in a trunk
on the switch should be connected to the lowest numbered port
of the trunk on the other device, the next lowest numbered port
on the switch should be connected to the next lowest numbered
port on the other device, and so on.
For example, assume that you are connecting a trunk between
two AT-8350GB switches. On the first AT-8350GB switch you
choose ports 12, 13, 14, 15 for the trunk. On the second AT-
8350GB switch you choose ports 21, 22, 23, and 24. To
maintain the order of the port connections, you would
connect port 12 on the first AT-8350GB switch to port 21 on
the second AT-8350GB, port 13 to port 22, and so on.
The example in Figure 18 shows a port trunk of four data links between
two AT-8350GB switches.
