Name: "updatechanstatus",

Category: "Channels",
|
||
|
|
Usage: "Set the status of an existing channel on the network.",
|
||
|
|
Description: `
|
||
|
|
Set the status of an existing channel on the network. The actions can
|
||
|
|
be "enable", "disable", or "auto". If the action changes the status, a
|
||
|
|
message will be broadcast over the network.
|
||
|
|
|
||
|
|
Note that enabling / disabling a channel using this command ONLY affects
|
||
|
|
what's advertised over the network. For example, disabling a channel
|
||
|
|
using this command does not close it.
|
||
|
|
|
||
|
|
If a channel is manually disabled, automatic / background requests to
|
||
|
|
re-enable the channel will be ignored. However, if a channel is
|
||
|
|
manually enabled, automatic / background requests to disable the
|
||
|
|
channel will succeed (such requests are usually made on channel close
|
||
|
|
or when the peer is down).
|
||
|
|
|
||
|
|
The "auto" action restores automatic channel state management. Per
|
||
|
|
the behavior described above, it's only needed to undo the effect of
|
||
|
|
a prior "disable" action, and will be a no-op otherwise.`,
