Description
The CM is being reset and will shortly restart the registration process.
The CM had registered and was online, but has received a Downstream
Channel Change (DCC) or Upstream Channel Change (UCC) request
message from the CMTS. The CM has begun moving to the new channel, and
the CMTS has received the CM's initial ranging on the new downstream or
upstream channel. At the MAC layer, the CM is considered offline because it
is not yet passing traffic on the new channel, but this state does not trigger the
flap-list counters.
This state should normally follow cc(r1) and indicates that the CM has
finished its initial ranging on the new channel, and is currently performing
continuous ranging on the new channel. At the MAC layer, the CM is
considered offline because it is not yet passing traffic on the new channel, but
this state does not trigger the flap-list counters.
The CM is considered offline (disconnected or powered down).
The CM has registered and is enabled to pass data on the network.
The CM registered, but network access for CPE devices using this CM has
been disabled through the DOCSIS configuration file. The CM does not
forward traffic to or from the CPE devices, but the CMTS can continue to
communicate with the CM using DOCSIS messages and IP traffic (such as
SNMP commands).
If BPI was enabled in the DOCSIS configuration file sent to the CM,
Note
assume that the CM is using BPI encryption, unless other messages
show that the BPI negotiation and key assignments have failed.
The CM registered, but network access for CPE devices using this CM has
been disabled through the DOCSIS configuration file. In addition, BPI is
enabled and KEK is assigned.
This state is equivalent to the online(d) and online(pk) states.
Note
The CM registered, but network access for CPE devices using this CM has
been disabled through the DOCSIS configuration file. In addition, BPI is
enabled and TEK is assigned. BPI encryption is now being performed.
This state is equivalent to the online(d) and online(pt) states.
Note
The CM registered, BPI is enabled and KEK is assigned.
The CM registered, BPI is enabled and TEK is assigned. BPI encryption is
now being performed.
If network access was disabled in the DOCSIS configuration file sent
Note
to the CM, the network disabled status takes precedence, and the
MAC status field shows online(d) instead of online(pt) even when BPI
encryption is enabled and operational.
If an exclamation point (!) appears in front of one of the online states, it indicates that the
dynamic-secret
command has been used with either the mark or reject option, and that the
cable modem has failed the dynamic secret authentication check.
