Brocade ICX 7250 Recommendations and Restrictions

1. A two port or eight port POD license is required for ICX 7250 stacking.

2. Only ports recognized as default ports can be used as stacking ports. Before a unit can use no

default stacking ports, the default-ports command must be configured on the local console for the

unit so the unit can be discovered by the secure-setup utility used to form a stack.

3. Default ports cannot be changed on a live stack. The following example shows the error message

displayed if you attempt to do so.

ICX7250-24P Switch(config-unit-1)#stack unit 3

ICX7250-24P Switch(config-unit-3)#default-ports 3/2/5 3/2/7

New default-ports 3/2/5 3/2/7 result in removing both old stack ports. Abort

4. If there are any wrong stack trunk connections, secure setup will not be performed. An invalid stack

trunk message or no new units discovered messages will be displayed.

5. Secure setup will not be performed if the setup has loops.

ICX7250-24P Switch# stack secure

CPU utilization too high: 92 percent. Check loops in the network and try again...

6. In case of any image mismatch on member units, active unit will trigger Autocopy. Autocopy is

supported only between minor and patch releases and not between major releases.

7. When a uplink port is being converted to stacking ports, the uplink configuration should be removed

before it can be configured as a stack port.
