Undocumented Cisco Commands

Undocumented Commands in Cisco IOS

[A] | [B] | [C] | [D] | [E] | [F] | [G] | [H] | [I] | [J] | [K] | [L] | [M] | [N] | [O] | [P] | [Q] | [R] | [S] | [T] | [U] | [V] | [W] | [X] | [Y] | [Z]

[A]
aaa accounting delay-start
[12.1] [hidden] global configuration command aaa accounting delay-start
delays creation of the PPP Network start record until the peer IP
address is known.
aaa authorization address-authorization-exec
[12.1] [hidden] configuration command forces address authorzation for
PPP when started from an exec.
aaa group server {radius | tacacs+} server-group-name
server ip-address-1 [auth-port port-number] [acct-port port-number]
server ip-address-2 [auth-port port-number] [acct-port port-number]
deadtime minutes pick-method [next | load-balanced | round-robin]
[hidden] pick-method server-group configuration command is used to specify
an alternate
method of selecting servers when one is not responding. As of 12.0(3)T
the load-balanced and round-robin alternatives may be specified but
may not be implemented. The Load-balanced keyword indicates that the
initial host is selected load-balanced. The Round-robin keyword
indicates that the initial host is selected in a round-robin method
with all servers being retried before starting from the beginnng of
the list of servers. The Next keyword indicates that the list of
servers is stepped through sequentially with each request always
starting with the first server in the list. This last option is the
default method of operation.
aaa nas port description text
[hidden] global configuration command causes the specified text to
appear in TACACS+ accounting records with the attribute nas-description
and the value of the text specified in the command.
This command is useful during debugging allowing one to specify
information about the environment or configuration in which the
accounting record was generated.
access-list number remark comment
and
ip access-list extended name
remark comment
[12.1]To add comments about the access list. This keyword is documented
under Bug Id CSCdk14543.
atm allow-max-vci
interface command, will allow the cisco 7000 use VCI's above 1023.

clear startup-config
same as erase startup-config)
clear vtemplate
reset virtual templates
clock rate { 1200 | [...]| 2015232 }
[hidden] There is an anomaly between what is documented, what is
displayed and what is entered for this command. The documentation
indicates the command is clock rate and this is what IOS shows as
the valid command in configuration mode. However, a configuration
display shows the command as clockrate as this is how is is saved in
nvram. In addition, older rom monitors do not understand the newer
clock rate command which would cause problems. What actually happens
here is that clockrate is implemented as a hidden command and is not
completed by pressing tab and nor is there any help generated for it.
But both clockrate and clock rate are accepted and there should
be no problem in cutting and pasting the configurations.

ipx flooding-unthrottled
[12.1] global configuratiom command specifies that NLSP flooding should
be unthrottled.
ipx netbios-socket-input-checks
[12.1] global configuratiom command limits the input of non-type 20
netbios bc packets
ipx potential-pseudonode
[12.1] global configuration command specifies to keep backup route and
service data for NLSP potential pseudocode.
ipx sap follow-route-path
[12.1] An undocumented global configuration command. See Bug Id
SCdm12190 for details.
ipx server-split-horizon-on-server-paths
[12.1] global configuratiom command specifies that split horizon SAP
occurs on server, not route, paths. This command is documented in Bug Id
CSCdm12190.
ipx update interval {rip | sap} {seconds | passive | changes-only}
[12.1] The undocumented passive keyword specifies to listen but does not
send normal periodic SAP updates nor flashes/changes updates. Queries
will still be replied to. The update interval is set to the same
interval as changes-only. The passive keyword is documented under Bug
Id CSCdj59918.
isdn {n200 | t200 | t203} number
[hidden] commands change the value of various layer 2 ISDN timer
settings. The number parameter is milliseconds for t200 and t203 and
the maximum number of retransmits for the keyword n200. The current
value of ISDN timers can be displayed using the show isdn
timers EXEC command.The values of the timer settings depend on the
switch type and typically are used only for homologation purposes.
The typical value for t200 is 1 second, for t203 is 10 seconds and
for n200 is 3 retransmits.

[L]
llc attach [interface]
llc close aaaa
llc offset aaaa
llc open [interface]
llc send aaaa
logging event {link-status | subif-link-status}
The no form of the undocumented logging event link-status interface
commmand is used to turn off sending up, down and change messages for an
interface to the syslog. This is very useful on live systems since
these systems generate so many of these messages that other important
messages are often hard to see. This is a companion command to the
documented command no snmp trap link-status which prevents sending the
associated snmp trap.

[M]
memory scan
Parity check for 7500 RSPs
modem log {cts | dcd | dsr | dtr | ri | rs232 | rts | tst}
[12.1] configuration command is used to specify which rs232 log events
are to be saved for display by the show modem log command. When
performing log analysis, various RS232 events fill the log within
seconds rendering it useless for analysis (see Bug Id CSCdk86001).
This command helps to filter out unwanted entries in the log.
modem-mgmt csm debug-rbs
[12.1] turns on debugging for Channelized T1 links in the AS5x00
series, providing info about ABCD bits in phone call supervision.
Documented, here. Debug cas replaced this 'broken' command.
INTERNAL privileged EXEC command enables robbed bit signaling debugging
within CSM. Issuing the command once turns on rbs debugging. Issueing
the command a second time turns on special rbs debugging. Issuing
the command using the no-debug-rbs keyword turns off all degugging.
This command is useful in looking at modem pooling and channelized
T1s. To make this command available, the service internal global
configuration command must be issued first.
multilink bundle-name {authenticated | both | endpoint}
[12.1] This undocumented global configuration command selects the method
for naming multilink bundles. "authenticated" specifies using the
peer's authenticated name, "endpoint" specifies using the peer's
endpoint discriminator and "both" specifies using both the peer's
authenticated name and endpoint discriminator.

Disable environment monitoring
[no] ppp chap ignoreous

[no] service password-recovery
For the daring people, it can be undone but *please* only specify this if you know what you are doing. and since this is undocumented, you probably don't! :-)

[A] | [B] | [C] | [D] | [E] | [F] | [G] | [H] | [I] | [J] | [K] | [L] | [M] | [N] | [O] | [P] | [Q] | [R] | [S] | [T] | [U] | [V] | [W] | [X] | [Y] | [Z]

[P]
ppp direction {callin | callout | dedicated}
[12.1] [hidden] identify the direction of ppp activity. PPP attempts to
determine if a call is callin or a callout or a dedicated line. This is
how it detects spoofed CHAP challenges. When an async interface is
added to a dialer interface, ppp cannot detect the difference between
a dedicated line and a callin. So it assumes that it is a callin.
Adding the ppp direction dedicated overcomes this.
ppp ipcp accept-address
[hidden] interface command specifies that IOS is to revert to the
previous operation regarding the acceptance of ip addresses from
users. When enabled, the peer IP address will be accepted but is still
subject to AAA verification, it will have precedence
over any local address pool however. In IOS releases after 11.0(11),
PPP IPCP negotiation was changed to accepts a remote peer's
"Her" proposed address regardless, and the "Her" address is
subsequently added to the IP routing table as a host route.
With IOS Releases later than 11.0(11) the software checks the
"Her" address against the corresponding dialer map and if the address
is different than the IP address detailed within the dialer map,
a NAK will be sent and the dialer map IP address will be added as
a host route in the IP routing table.
ppp ipcp ignore-map
ppp lcp fast-start
[12.1] interface configuration command specifies to ignore the carrier
timer and start PPP when an LCP packet arrives.
ppp restart-timer msec
[hidden] interface configuration command modifies the default value
(2 seconds) for the restart timer. The translate command also has a
similar keyword, restart.
ppp timeout absolute <sec>
Determines how long PPP link can be up [default is infinity, configurable as 0] used under virtual-template interfaces.
ppp timeout idle <sec> inbound
ppp timeout idle <sec> either
Determines how long PPP can wait until bringing the link down if there
is no traffic. [default is infinity, configurable as 0] used under
virtual-template interfaces.
profile <start> <stop> <granularity>

[A] | [B] | [C] | [D] | [E] | [F] | [G] | [H] | [I] | [J] | [K] | [L] | [M] | [N] | [O] | [P] | [Q] | [R] | [S] | [T] | [U] | [V] | [W] | [X] | [Y] | [Z]

[R]
radius-server attribute 44 on-for-access-req
[hiden] global configuration command sends attribute 44 in all access
request packets. The command may be present in IOS 11.3(9+)AA
(reference BugID CSCdk74429). This command is replaced by the
radius-server attribute 44 include-in-access-req command.
radius-server attribute 6 on-for-login-auth
[hidden] global configuration command sends attribute 6 in all
authentication packets (e.g., access requests). This command may be
present in IOS 11.3(9+)T and 12.0(3+)T (reference
BugID CSCdk81561).
radius-server attribute 6 support-multiple
[hidden] global configuration command specifies that IOS is to support
multiple Service-Type values per Radius profile in violation of the
RFC for Radius. This command was added in IOS
12.1(2.3)T2 and 12.1(3.3)T (reference BugID CSCdr60306).
radius-server authorization default framed-protocol ppp
[hidden] used to specify the default framed-protocol as PPP when this
RADIUS attribute is missing.
radius-server authorization permit missing service-type
[hidden] global command is used to specify that a RADIUS entry without
service-type information is permitted. It is used when RADIUS is being
used as a database without regard to service-type.
radius-server attribute nas-port extended
[hidden?] command is replaced by the radius-server attribute nas-port
format b command in some releases of IOS. For this reason it may be
hidden in the IOS configuration mode but documented. In these
versions of IOS, the command will be accepted but ignored.
radius-server challenge-noecho
[12.1] global configuration command specifies that data echoing to the
screen is disabled during Access-Challenge.
radius-server directed-request [restricted] [right-to-left]
[hidden] right-to-left keyword, which first appeared in IOS 12/0(7)T,
enables right-to-left parsing of the user information (reference
Bugid CSCdm77820).
radius-server extended-portnames
[hidden] global configuration command, which displays expanded interface
information in the NAS-Port-Type attribute, has been replaced by the
radius-server attribute nas-port extended command.
This command configures RADIUS to expand the size of the NAS-Port
attribute field to 32 bits.
The upper 16 bits of the NAS-Port attribute display the type and number
of the controlling interface; the lower 16 bits indicate the
interface undergoing authentication.
This command first appeared in IOS Release 11.1. It has been hidden in
IOS 11.3+ and IOS 12.0+ since the command has been replaced
(reference Bugid CSCdj06817).
radius-server host {hostname | ip-address} [auth-port port-number]
[acct-port port-number] [timeout seconds] [retransmit retries]
[key string] [ignore-acct-authenticator]
[hidden] ignore-acct-authenticator keyword specifies to ignore
accounting authenticator errors and warn only (11.3(+)AA).
radius-server ipc-limit done limit
[hidden]
radius-server retry method round-robin
[hidden] global configuration command is used to specify an alternate
method of selecting servers when one is not responding. As of 12.0(3)T
alternates may not be defined and the round-robin alternative may not
be implemented.
radius-server secret string
[hidden] global configuration command is used to specify the key shared
with the RADIUS server. This command is hidden because it has been
replaced with the radius-server key command (reference
BugID CSCdi44081). This command first appeared in IOS Release 11.1.
radius-server unique-ident value
[hidden] global configuration command is used to set high order bits for
the accounting identifier. The identifier field is a one octet field
included in all RADIUS accounting packets which aids in matching
requests and replies.

show mbuf
Catalyst 5000, The main issue to observe with this command is whether
the switch is being starved for memory. Within the display, "clusters"
is the number of buffers that are available for NMP to process
incoming packets, which include any broadcast/multicast, management
traffic. "clfree" is the number of buffers that are available for the
NMP at any given time.
If this is zero then this means that NMP has no buffers to process any
incoming frames. "lowest clfree" determines the lowest watermark that
NMP has hit at any time. If this value is zero but clfree is nonzero,
then this means that at one instance NMP ran out of buffers. This
can be because of a broadcast of a multicast storm in the management
vlan.

snmp-server priority {low | normal | high}
[hidden] global configuration command can be used to change the
priority of SNMP processes. To avoid extensive polling, use the
priority should be set to low . All SNMP queries sent to a router
are prioritized as either low or medium priority, depending on the
version of code run by the route processor. This means that processes
with a higher priority than the SNMP process will be serviced before
SNMP. So, regardless of SNMP polling intensity, routing processes will
generally be processed before SNMP requests because route processes
are "high" priority. You can view the priorities of each of the
router's processes by doing a show process and looking in the Q column
(L == Low, M == Medium, H == High). See
http://www.cisco.com/warp/public/490/9.html for documentation.
This command has no impact on the priority of the snmp trap process.
[no] snmp-server sparse-tables

test voip scripts
allow to run self-created IVR (Interactive Voice Response) scripts.
Cisco included 7 IVR scripts in IOS. Self-created scripts must be
specially signed. Issuing this command in priviliged mode before loading
self-created script you turn off the signature checking procedure. The
only problem is that the command must be issued every each router
reboot. Cisco promises to remove totally the signature checking
procedure in future IOS releases.

set trace
If you enter set trace ?, nothing appears however if you enter
set trace followed by anything else you will see the command
options. Be careful with this command, make a backup of the
configuration FIRST. You can saturate the processor if it is
used inappropriately the Catalyst may reboot constantly or
become non responsive upon boot! In this case you have to break
in and wipe the config very quickly.
