Runtime Configuration Mismatch

In some cases, such as a runtime configuration mismatch between the active controller and candidate standby controller, the standby controller cannot be assigned by the active controller unless the candidate standby controller is reloaded.

Samples in this section must be replaced with samples from a model other than the ICX 7750.
As shown in the following example, the show stack command output indicates whether there is a runtime configuration mismatch. 

device# show stack
alone: standalone, D: dynamic config, S: static config

1  S ICX7750-48XGC   active 0000.0001.0000  30  local  Ready
2  d ICX7750-48XGC   member 0000.0002.0000  20  remote Ready, standby if reload

 -2/1| 2 |2/2--2/1| 1 |2/2-
     +---+        +---+
Note: There is no standby. Reason: u2: diff runtime config
Current stack management MAC is 0000.0001.0000
Note: no "stack mac" config. My MAC will change after failover.
