To configure a trunk between switch 1 and switch 2, each with port 1-4 in the trunk
group.
Type the following commands on each switch:
Switch# trunk
Trunk_id: 1
Trunk_rtag: 1
Ports _list: 1-4
Notes:
When configuring a trunk, both switches should have the same number of ports in the trunk, with
the same speed and duplex configuration, but the port identification number can be different.
To delete a trunk group
Switch# no trunk A
A: trunk id, range: 0-5
To check any error
(1). If the trunk doesn't work, check the status:
switch# show trunk
TGID RTAG
0 0
1 1
2 0
3 0
4 0
5 0
Thus you can check whether the configured trunk is active, whether the included ports number is
correct and whether member ports are correct.
(2) Ports in the same trunk should belong to the same vlan, with the same speed and
duplex configuration.
