Updating configuration settings about devices

WalT allows users to show or modify device configuration settings by using commands walt device config or walt node config. For instance:

$ walt device config switch1                    # show
$ walt device config switch1 lldp.explore=true  # modify
$ walt node config virt-node ram=384M           # modify

One may also show or change several settings at once, and/or show or update them on several devices at once. (See also: walt help show device-sets) For instance:

$ walt device config all-switches               # show
$ walt device config all-switches lldp.explore=true poe.reboots=true
$ walt node config virt-node-1,virt-node-2 ram=384M

You can also use this command to indicate to walt server that an unknown device is actually a switch:

$ walt device config unknown-a2f2d3 type=switch

Here is the set of settings currently allowed:

Name	possible values	Applies to:	Notes

poe.reboots	true or false	switches
snmp.version	1 or 2	switches
snmp.community	e.g. ‘private’	switches
type	‘switch’	‘unknown’ devices
netsetup	‘NAT’ or ‘LAN’	devices of walt-net
ram	e.g. ‘384M’ or ‘1G’	virtual nodes
cpu.cores	e.g. 1 or 4	virtual nodes
disks	e.g. ‘8G’ or ‘32G,1T’	virtual nodes
