The command configures a node to be allowed to operate as either a backup or master, or prevents a node from operating as either.
The command controls the setting on the specified node only. To set the master capability for all nodes on a stack, you can use the command configure stacking redundancy [none | minimal | maximal].
| node_address | Specifies the MAC address of a node in the stack. To view the MAC addresses for all nodes in a stack, enter the show stacking command. |
| slot_number | Specifies the slot number of the target active node. To view the slot numbers, enter the show stacking command. |
Master-capability is On.
At least one node in the stack topology must be master-capable.
If you attempt to disable the master-capability of the only master capable node in a stack topology, the attempt is denied and following message appears:
Error: At least one node must have Master-capability configured "on".This command is used to set up master-capability manually. It can also be used to adjust the result achieved when the configure stacking redundancy [none | minimal | maximal] command is used.
The setting takes effect the next time the node reboots. When this command is executed successfully, the following message appears:
This command will take effect at the next reboot of the specified node(s).To turn on the master capability for a node:
configure stacking node-address 00:04:96:26:6b:ed master-capability on
To turn on the master capability of an active node currently occupying slot 4:
configure stacking slot 4 master-capability on
This command was first available in ExtremeXOS 12.0.
