FP_DRV-4:
PrismImmFastPath::Send: Could
not allocate an MCID. Remote
message send aborted.
The CSS MIPS processor attempts to
send a group message, but the
processor cannot obtain an multicast
ID (MCID) from the Multicast ID
Module (MID). The MID keeps track
of the reference count on a buffer when
the CSS sends a packet to multiple
locations. The fast path uses an MCID
to reference count the buffer with a
contained packet that is being flooded
to all ports in a VLAN.
For MCIDs to be depleted in the CSS,
there must be 1024 reference counted
packets queued up in some
combination of hardware queues and
software queues.
To fill up hardware queues, the CSS
must receive a large number of packets,
which it then chooses to flood out all
ports.
