NAME¶
ng_hub —
packet distribution netgraph node type
DESCRIPTION¶
The hub node type provides a simple mechanism for
distributing packets over several links. Packets received on any of the hooks
are forwarded out the other hooks. Packets are not altered in any way.
HOOKS¶
A hub node accepts any request to connect, regardless of
the hook name, as long as the name is unique.
CONTROL MESSAGES¶
This node type supports the generic control messages, plus the following:
NGM_HUB_SET_PERSISTENT
(setpersistent)- This command sets the persistent flag on the node, and takes no
arguments.
SHUTDOWN¶
This node shuts down upon receipt of a NGM_SHUTDOWN
control message, or when all hooks have been disconnected. Setting the
persistent flag via a NGM_HUB_SET_PERSISTENT control
message disables automatic node shutdown when the last hook gets disconnected.
HISTORY¶
The ng_hub node type appeared in
FreeBSD 5.3.
