Modes
User EXEC mode
The
show stack command displays the following information:
| Output field | Description |
|---|---|
| ID | Specifies the identification number of the stack unit. Each unit in the stack has a unique ID number. |
| Type | Specifies the type (model) of the stack unit. |
| Role | Specifies the role of the stack unit. The roles are controller, standby, or member. |
| Mac Address | Specifies the MAC address of the stack unit. The roles are controller, standby, or member. |
| Pri | Specifies the priority value assigned to the stack unit. The default value is 128. |
| State | Specifies whether the stack unit is local or remote. A unit with a State value of Local is the active controller. Units with a State value of Remote are either standby units or member units. |
| Comment | Indicates if the stack unit is ready (available). |
| Role history | Tracks up to six role changes per stack unit. The initial state is always displayed. Overflow is indicated by ellipses (...). Standby to member role changes are not displayed. Role history also does not display the transition after bootup of a non-active controller unit from member to standby. |
