IOS-XE 3.15.0S
|
This
command was implemented on the
Cisco cBR Series Converged
Broadband Router. The
name,
queue
keyword and the
logical-channel-index variable were removed.
|
Usage Guidelines
This command
displays information for all cable modems, for all cable modems attached to a
specific CMTS cable interface, or for a particular cable modem, identified by
its IP address, MAC address, or its domain name. The output is sorted by the
cable interface and the cable modem’s MAC address.
Note |
In Cisco IOS
Release 12.2(33)SCA, the
show
cable
modem
domain-name command must be run first on the route
processor (RP) of the CMTS router before any domain name can be used as part of
a cable command.
|
Tip |
Several
options in the
show
cable
modem command do not pause the screen to display
the information page by page, even if the
terminal
length command has been used to set the page size
of your terminal. Paging and pausing the display could result in outdated or
stale information for cable modems, and thus produce an incorrect snapshot of
the current cable modem state of the system. To capture or review this
information, use your terminal program’s capture buffer to save the information
to a file, and then review it offline.
|
Tip |
You can also
specify the MAC address or IP address for a CPE device, and the Cisco CMTS will
display the information for the cable modem that is associated with that CPE
device in its internal database.
|
Note |
If the CPE
IP address is no longer associated with a cable modem, the
show
cable
modem command might not display information about
the cable modem. To display the IP address of the CPE device for the cable
modem, use the
clear
cable
host
ip-address
command to clear the IP address of the modem from the router database, and then
enter the
ping
docsis
mac-address
command, which resolves the MAC address by sending the DOCSIS ping to the CM.
|
Note |
When an IPv4
CPE is moved from one bundle interface to another bundle interface, the
show
cable
modem command displays duplicate CPE device under
the original modem and new modem. CPE ping may also fail. To prevent
duplication, use the
clear
cable
host command to manually remove the old CPE device
entry before moving the IPv4 CPE from one bundle interface to another. Reload
the CPE after moving it to another bundle interface.

Refer to the
following document on Cisco.com for additional information about cable
interface bundling and virtual interface bundling on the Cisco CMTS:

Cable
Interface Bundling and Virtual Interface Bundling on the Cisco CMTS
Operation with Hot
Standby Connection-to-Connection Protocol (HCCP) Configuration
If you are
using Hot Standby Connection-to-Connection Protocol (HCCP) 1+1 or 1:n (N+1)
redundancy, the new primary processor after a switchover automatically creates
a new database of the online cable modems. This means that the
show
cable
modem
ip-address
command might not show a particular cable modem until the CMTS receives IP
traffic from that cable modem. You can force IP traffic by using the
ping
ip-address
command, and then the
show
cable
modem
ip-address
command will show the cable modem. You can also display any particular cable
modem by using the
show
cable
modem
|
include
ip-address
command.
In addition,
when HCCP redundancy has been configured, the Cisco IOS software automatically
synchronizes the secondary, backup cards whenever the configuration is changed.
The cards can also be synchronized manually, using the
hccp
resync command. When a SYNC event command is
occurring, CLI commands might be very slow to respond. In particular, if you
enter the
show
cable
modem command at the same time a SYNC event is
occurring, the command might respond produce a blank display, or it might
display an error message similar to the following:
%No response from slot 6/1. Command aborted
If this occurs,
wait a minute or so and retry the command.
Operation of the show
cable modem Commands with Different Cable Interface Line Cards
The
show
cable
modem commands display the most current
information for standard cable interface line cards. If the card itself is
down, the
show
cable
modem commands still show whatever information is
appropriate (such as offline cable modems and flap list information).
The
show
cable
modem commands function slightly different when
used on routers that are using Broadband Processing Engine (BPE) cable
interface line cards (such as the Cisco uBR-MC16U/X, Cisco uBR-MC28U/X, or
Cisco uBR10-MC5X20S/U/H). When BPE cards are the only cable interface cards
installed, the
show
cable
modem commands do not display any output until at
least one BPE card is up and communicating with the router processor. If the
BPE cards are not yet up, the
show
cable
modem
command does not display any output.
Note |
The
hccp
commands are not supported on the
Cisco cBR router for
Cisco IOS-XE 3.15.0S.

max-cpe
command. In Cisco IOS Release 12.2(15)BC1 and later releases,
the
verbose
display also includes information about the dynamic shared-secret feature (see
the
cable
dynamic-secret
command).
|
Note |
An asterisk
(*) in the Receive Power column indicates that a power adjustment has been made
for that CM. An exclamation point (!) in the Receive Power column indicates
that the cable modem has reached its maximum power transmit level and cannot
increase its power level further. An exclamation point (!) in the Timing Offset
column indicates that the cable modem has exceeded the maximum delay and timing
offset specified by the
cable
map-advance command. A pound sign (#) in the MAC
State column indicates that the
cable
tftp-enforce
mark-only command has been used for the cable
modem to attempt a TFTP download of the DOCSIS configuration file before
registering, but the cable modem did not do so (Cisco IOS Release 12.1(11b)EC1
and Cisco IOS Release 12.2(8)BC2 or later releases).
|
Tip |
The
show
cable
modem command displays the cable modem timing
offset in DOCSIS ticks, while other commands, such as
cable
map-advance, display the offset in microseconds.
Use the following method to convert microseconds to DOCSIS ticks: ticks =
microseconds*64/6.25 .

and ‘N’ for disabled.
|
Upstream SNR
|
Upstream signal-to-noise ratio (SNR) for a particular cable modem (CM), in
decibels (dB).
|
Upstream SM MER (dB)
|
Upstream station maintenance (SM) modulation error ratio (MER) for a particular
cable modem, in decibels (dB).
|
Upstream Data MER (dB)
|
Upstream modulation error ratio (MER) for a particular cable modem, in decibels
(dB). This field is displayed only when RF adaptation is enabled.
|
RxPwr,
Received Power
|
Average
power in dBmV for the upstream channel symbol rate for the CM. With default
settings, 0 dBmV is considered optimal, but a range of -1 to 1 dBmV is
allowable. When cable modems exceed this range, older Cisco IOS releases
supported a drop to as low as -2 dBmV. Recent Cisco IOS releases support a drop
to as low as -4 dBmV.
This
field supports a resolution of 0.25 dBmV, but the dB resolution level for cable
modems and for the Cisco CMTS are slightly higher—approximately 1.0 and 1.4 dB.
Note
| An
asterisk (*) in the RxPwr column indicates that a power adjustment has been
made for that CM. An exclamation point (!) indicates that the cable modem has
reached its maximum power transmit level and cannot increase its power level
further.
|
|
Timing
Offset and Initial Timing Offset
|
Timing
offset for the CM, in ticks, as recognized on the CMTS. (A tick, as used here,
is 6.25/64 microseconds.) This is the delay between when a particular cable
modem is scheduled to make a transmission and when the CMTS actually receives
it.
Note
| An
exclamation point (!) in the Timing Offset column indicates that the cable
modem has exceeded the maximum delay and timing offset specified by the
cable
map-advance command.
|
Note
| The
timing offset shown here is typically smaller than the TX Time Offset value
shown by the
show
cable
modem
remote-query command, because the latter value is
the offset as recognized on the cable modem (which will include any internal
delay between when the cable modem software begins the transmission and when
the bits actually appear on the local cable interface).
|
|
Reported Transmit Power (dBmV)
|
Reported Transmit Power level by the cable modem for each upstream channel.
This applies only to the cable modems operating in the MTC mode.
|

the maximum transmit power level that the cable modem in the MTC mode could
transmit at for the upstream channel.
|
Minimum
Transmit Power (dBmV)
|
This is
the minimum transmit power level that the cable modem in the MTC mode could
transmit at for the upstream channel.

The table below
shows the possible values for the MAC state field.
Note |
The CM MAC
state field can also be retrieved using SNMP by getting the value of the
cdxCmtscable modemstatusValue object in the CISCO-DOCS-EXT-MIB. The following
symbols appended to the modem state indicate a special condition:An exclamation
mark (!) indicates that the cable dynamic-secret command is used with either
the mark or reject keyword and the cable modem has failed the dynamic secret
authentication check.An ampersand (and) indicates that the cable modem has
registered using a self-signed certificate. This is inherently not secure and
can be avoided by negating the cable privacy accept-self-signed-certificate
command.The asterisk () indicates that the cable modem does not satisfy the
BPI+ policy and the data traffic is blocked. The cable privacy bpi-plus-policy
command enforces this requirement.A hash sign () indicates that the cable modem
is using an unknown configuration file. To solve this problem, use the cable
dynamic-secret command with the reject keyword. This will reject registration
for cable modems with DOCSIS configuration files. In Cisco IOS Releases
12.1(20)EC, 12.2(15)BC1, and earlier releases, when network access is disabled
in the DOCSIS configuration file sent to the CM, the network disabled status
takes precedence, and the MAC status field shows online(d) even if BPI
encryption fails.

Ranging Status Conditions for Devices Using IPv4 Addressing
|
init(r1)
|
The
cable modem sent initial ranging.
|
init(r2)
|
The
cable modem is ranging. The CMTS received initial ranging from the cable modem
and has sent RF power, timing offset, and frequency adjustments to the CM.
|
init(rc)
|
Ranging
has completed.
Note
| If a
cable modem appears to be stuck in this state, it could be that the cable modem
is able to communicate successfully on the cable network, but that the upstream
is at capacity and does not have any additional bandwidth to allow the cable
modem to finish registration and come online. Either manually move one or more
cable modems to other upstreams, or enable load balancing on the upstream using
the
cable
load-balance
group commands.
|
|
Early
Authentication and Encryption
|
assign(epk)
|
BPI is
enabled and KEK is assigned.
|
assign(ept)
|
BPI is
enabled and TEK is assigned. The registration messages will be encrypted.
|
Registration and
Provisioning Status Conditions for Devices Using IPv4 Addressing
If
early authentication and encryption is used, the letter ‘s’ is appended to
these states to indicate secure registration.
|
init(d)
|
The
DHCP request was received, as DHCPDISCOVER. This also indicates that the first
IP broadcast packet has been received from the CM.
|
init(dr)
|
The
DHCP request has been sent to the cable modem.
|
init(i)
|
The
cable modem has received the DHCPOFFER reply (DHCPACK) from the DHCP server
that has assigned an IP address to the modem, but the modem has not yet replied
with a DHCPREQUEST message requesting that particular IP address, nor has it
sent an IP packet with that IP address.
Note
| If a
cable modem appears to be stuck in this state, the cable modem has likely
received the DHCPOFFER reply from the DHCP server, but this reply might have
contained one or more invalid options for that particular CM.
|
|
init(io)
|
The
Cisco CMTS has seen the DHCP offer as sent to the cable modem from the DHCP
server that has assigned an IP address to the modem.
|
init(o)
|
The
cable modem has begun to download the option file (DOCSIS configuration file)
using the Trivial File Transfer Protocol (TFTP), as specified in the DHCP
response. If the cable modem remains in this state, it indicates that the
download has failed.
|
init(t)
|
Time-of-day (TOD) exchange has started.
|
Registration and Provisioning Status Conditions for Devices
Using IPv6 Addressing
If
early authentication and encryption is used, the letter ‘s’ is appended to
these states to indicate secure registration.
|
init6(s)
|

server.
|
Non-error Status
Conditions
|
cc(r1)
|
The
cable modem had registered and was online, but has received a Downstream
Channel Change (DCC) or Upstream Channel Change (UCC) request message from the
CMTS. The cable modem 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 cable modem is considered offline because it is not yet
passing traffic on the new channel, but this state does not trigger the
flap-list counters.
|
cc(r2)
|
This
state should normally follow cc(r1) and indicates that the cable modem has
finished its initial ranging on the new channel, and is currently performing
continuous ranging on the new channel. At the MAC layer, the cable modem is
considered offline because it is not yet passing traffic on the new channel,
but this state does not trigger the flap-list counters.
|
offline
|
The
cable modem is considered offline (disconnected or powered down).
|
resetting
|
The
cable modem is being reset and will shortly restart the ranging and
registration process.
|
online
|
The
cable modem has registered and is enabled to pass data on the network.
|
online(d)
|
The
cable modem registered, but network access for CPE devices using this cable
modem has been disabled through the DOCSIS configuration file. The cable modem
does not forward traffic to or from the CPE devices, but the CMTS can continue
to communicate with the cable modem using DOCSIS messages and IP traffic (such
as SNMP commands).
Note
| If
BPI was enabled in the DOCSIS configuration file sent to the CM, assume that
the cable modem is using BPI encryption, unless other messages show that the
BPI negotiation and key assignments have failed.
|
|
online(pkd)
|
The
cable modem registered, but network access for CPE devices using this cable
modem has been disabled through the DOCSIS configuration file. In addition, BPI
is enabled and KEK is assigned.
Note
| This
state is equivalent to the online(d) and online(pk) states.
|
|
online(ptd)
|
The
cable modem registered, but network access for CPE devices using this cable
modem has been disabled through the DOCSIS configuration file. In addition, BPI
is enabled and TEK is assigned. BPI encryption is now being performed.
Note
| This
state is equivalent to the online(d) and online(pt) states.
|
|
online(pk)
|
The
cable modem registered, BPI is enabled and KEK is assigned.
|
online(pt)
|
The
cable modem registered, BPI is enabled and TEK is assigned. BPI encryption is
now being performed.
Note
| If
network access was disabled in the DOCSIS configuration file sent 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.
|
|
expire(epk)
|
Early
authentication and encryption is enabled, KEK was assigned, but the current KEK
expired before the cable modem could successfully renew a new KEK value.
|
expire(pkd)
|
The
cable modem registered, but network access for CPE devices using this cable
modem has been disabled through the DOCSIS configuration file. In addition, BPI
is enabled, KEK was assigned, but the current KEK expired before the cable
modem could successfully renew a new KEK value.
Note
| This
state is equivalent to the online(d) and expire(pk) states.
|
|
expire(ept)
|
Early
authentication and encryption is enabled, TEK was assigned, but the current TEK
expired before the cable modem could successfully renew a new KEK value.
|
expire(ptd)
|
The
cable modem registered, but network access for CPE devices using this cable
modem has been disabled through the DOCSIS configuration file. In addition, BPI
is enabled, TEK was assigned, but the current TEK expired before the cable
modem could successfully renew a new KEK value.
Note
| This
state is equivalent to the online(d) and expire(pt) states.
|
|
Error
Status Conditions
|
reject(m)
|
The
cable modem attempted to register but registration was refused due to a bad
Message Integrity Check (MIC) value. This also could indicate that the shared
secret in the DOCSIS configuration file does not match the value configured on
the CMTS with the
cable
shared-secret command.
In
Cisco IOS Release 12.1(11b)EC1 and Cisco IOS Release 12.2(8)BC2 or later
releases, this could also indicate that the
cable
tftp-enforce
command has been used to require that a cable modem
attempt a TFTP download of the DOCSIS configuration file before registering,
but the cable modem did not do so.
|
reject(c)
|
The
cable modem attempted to register, but registration was refused due to a a
number of possible errors:
- The cable modem
attempted to register with a minimum guaranteed upstream bandwidth that would
exceed the limits imposed by the
cable
upstream
admission-control command.
- The cable modem has been
disabled because of a security violation.
- A bad class of service
(COS) value in the DOCSIS configuration file.
- The cable modem
attempted to create a new COS configuration but the CMTS is configured to not
permit such changes.
- The cable modem failed
the timestamp check for its DOCSIS configuration file. (This could indicate a
possible theft-of-service attempt, or a problem with the synchronization of the
clocks on the cable modem and CMTS.)
|
reject(epk)
|
Early
authentication and encryption is enabled, KEK key assignment is rejected, and
the modem has not been authenticated.
|
reject(pk)
|
KEK key
assignment is rejected, and the modem has not been authenticated.
|
reject(pkd)
|
The
cable modem registered, but network access for CPE devices using this cable
modem has been disabled through the DOCSIS configuration file. In addition, BPI
encryption was not established because KEK key assignment was rejected.
Note
| This
state is equivalent to the online(d) and reject(pk) states.
|
|
reject(ept)
|
Early
authentication and encryption is enabled, TEK key assignment is rejected, and
BPI encryption has not been established.
|
reject(ptd)
|
The
cable modem registered, but network access for CPE devices using this cable
modem has been disabled through the DOCSIS configuration file. In addition, BPI
encryption was not established because TEK key assignment was rejected.
Note
| This
state is equivalent to the online(d) and reject(pt) states.
|
|
reject(ts)
|
The
cable modem attempted to register, but registration failed because the TFTP
server timestamp in the cable modem registration request did not match the
timestamp maintained by the CMTS. This might indicate that the cable modem
attempted to register by replaying an old DOCSIS configuration file used during
a prior registration attempt.
|
reject(ip)
|
The
cable modem attempted to register, but registration failed because the IP
address in the cable modem request did not match the IP address that the TFTP
server recorded when it sent the DOCSIS configuration file to the CM. IP
spoofing could be occurring.
|
reject(na)
|
The
cable modem attempted to register, but registration failed because the cable
modem did not send a Registration-Acknowledgement (REG-ACK) message in reply to
the Registration-Response (REG-RSP) message sent by the CMTS. A
Registration-NonAcknowledgement (REG-NACK) is assumed.
|
Tip |
In Cisco IOS
Release 12.1(12)EC, Release 12.2(8)BC1, and later releases, you can add a
timestamp to
show
commands using the
exec
prompt
timestamp command in line configuration mode.
