Description (partial)


If the Blaze key index allocation fails for an encrypted mcast session, the traffic will be sent 
unencrypted. Index allocation might fail due to an IPC drop between the host and the guardian, or 
because the guardian is down.


Multicast traffic will be sent in the clear. Also upon key renewal, blaze index 0 (for deault 
traffic) is over written with the new key and all traffic is encrypted, causing the modem to go 
offline and come back and get stuck in the init(io) state.
