Brocade FastIron Ethernet Switch Stacking Configuration Guide - Manual (Page 88)

NOTE
If you are building a stack using secure-setup, you do not have to enter stack enable on each unit.
2. Check that all of your stacking port connections are secure and working properly. Enter show
interface stack on each device to confirm that the stacking port links are up and the ports are in
the forward state.
device# show interfaces stack
Port Link State Dupl Speed Trunk Tag P MAC Name
1/2/1 Up Forward Full 10G None No 1 0000.00eb.a902
1/2/2 Up Forward Full 10G None No 1 0000.00eb.a904
3. Confirm that all of the devices are running the same software image.
4. Use the show log command to display any IPC version mismatch messages. These messages
appear in one minute when receiving mismatched probe packets, and then once every 10
minutes.
5. Use the show stack ipc command to see if any traffic has been sent or received. Enter clear
stack ipc to clear the traffic statistics and then enter show stack ipc again so you can easily see
differences in traffic flow. The following output is from an ICX 6610 switch.
device# show stack ipc

Possible errors:
*** recv from non-exist unit 2 times: unit 5
If the send message types: field is empty, it means that stack enable has not been configured. If
the number of Recv IPC packets increases, but there are no Recv message types, then the
packets are being dropped for various reasons, including the wrong IPC version, or a checksum
error. The Possible errors field will list reasons for packet loss.
NOTE
A small "***state not ready" count is normal, but if it continues to increase a problem is indicated.
6. If the results of a show stack command show other stack members, but lists them as non-
operational, this could be due to an image mismatch, or a configuration mismatch. In the event of
an image mismatch, you can download the correct images to the entire stack from the active
controller.
