ImportantThe Settings object persists and overrides the configuration files, storing both settings and passwords for the cluster. See Swarm Passwords. |

PracticeAlways change settings using the Swarm UI, rather than through the configuration files. |
There are several benefits to this practice:
No reboot required. No need to perform a full reboot for the configuration change to take effect.
Updates persisted settings. The changes are stored directly in the Settings object.
Only update in one place. Only need to update persisted settings on one node: Swarm propagates the changes to all other Settings objects in the cluster.

Note
{node} is the IP address of any Swarm storage node. {password} is the SNMP read-write community as specified via the snmp.rwCommunity cluster setting.
Listed below are the special Swarm settings with SNMP names, as well as whether they are persisted and writable. All are configurable using the Swarm UI.
