Hola a todos
Les lejo un par de comendos, los cuales no estan documentados, espero que les sea util. Son aproximadamente 29 hojas A4.
COMANDOS CISCO IOS NO DOCUMENTADOS
Tomado de : http://boerland.com/dotu (Project DOTU: Document The Undocumented VERSION: 2001.08.25)
http://www.heinzulm. com/hu03.html (Heinz Ulm’s collection of undocumented OSPF, EIGRP and interface commands with samples
[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 authorization 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 beginning 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.

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 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.

debug eigrp neighbor [ sia-timer ]
this will print debug information about the operation of the sia timers. Generally not very useful (unless you are testing the timers)

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.
