in.cdpd
actively listens for other hosts,
and advertises the local machine to connected network interfaces using the
Cisco Discovery Protocol (CDP). Local network interfaces available for use
are those which implement dlpi(4P) and
act as Ethernet provider nodes. in.cdpd
will connect
to each provider node, and register with it to read raw datalink frames in
order to parse CDP.
When the in.cdpd
service starts, it
requests multicast promiscuous mode on all Ethernet style interfaces, and
begins processing raw multicast frames, scanning for those that match the
CDP multicast address and LLC header. The DLPI layer does not explicitly
specify the ability to bind to, and listen for LLC frames, so
in.cdpd
binds to the typically unused SAP address of
0x0000, and enables raw mode processing.
The associated cdpadm(8) utility can be used to display status data from the running daemon.
