then the problem is with the cable or the other network device.
Verify that the twisted pair cable does not exceed 100 meters (328
feet).
Verify that you are using the appropriate category of twisted pair
cable. Cable requirements are listed in Table 5 on page 28.
Verify that the port is connected to the correct twisted pair cable.
Note
An 1GBase/10GBase connection may require five to ten seconds to
establish a link.
Problem 9:
The SHOW STACK command is not displaying all the
switches in the stack.
Solutions:
The switches are unable to form the stack. Try the following:
The switches might have an earlier version of the management
software that does not support VCStack, or they might have
different versions. The version must be 5.4.8-2 or later. You can
view the version number with the SHOW VERSION command.
Review the information in “Stack Trunks” on page 50 to verify that
the trunk complies with all rules and restrictions.
If the trunk is using fiber optic transceivers, verify that they are fully
inserted into the ports.
Verify that the transceivers are from Allied Telesis.
Verify that the fiber optic cables are securely connected to the
ports on the transceivers.
Display the running configurations and confirm the ports of the
stack trunk. They are identified by the STACKPORT command. In
this example from a running configuration, ports 1 to 4 are the
stack trunk:
interface port1.0.1-1.0.4
stackport
If necessary, repeat the STACKPORT command. For information,
refer to “STACKPORT” on page 122. Afterwards, save your
changes and reboot the switch.
Problem 10:
You removed a port from a stack trunk with the NO
STACKPORT command, but the port is still not forwarding regular
Ethernet traffic.
Display the running configuration to verify that the port is no longer
part of the stack trunk.
You have to reboot the switch whenever you add a port to a stack
trunk with the STACKPORT command or remove a port with the
