Lock-and-Key Commands

This chapter explains the function and syntax of the Lock-and-Key commands. For more information about defaults and usage guidelines, see the corresponding chapter of the Cisco IOS Security Command Reference, Release 12.1.

acc es s-enable

To enable the router to create a temporary access list entry in a dynamic access list, use the access-enable EXEC command.

access-enable [host] [timeout minutes]

Syntax Description

host

(Optional) Tells the software to enable access only for the host from which the Telnet session originated. If not specified, the software allows all hosts on the defined network to gain access. The dynamic access list contains the network mask to use for enabling the new network.

timeout minutes

(Optional) Specifies an idle timeout for the temporary access list entry. If the access list entry is not accessed within this period, it is automatically deleted and requires the user to authenticate again. The default is for the entries to remain permanently. We recommend that this value equal the idle timeout set for the WAN connection.

host	(Optional) Tells the software to enable access only for the host from which the Telnet session originated. If not specified, the software allows all hosts on the defined network to gain access. The dynamic access list contains the network mask to use for enabling the new network.
timeout minutes	(Optional) Specifies an idle timeout for the temporary access list entry. If the access list entry is not accessed within this period, it is automatically deleted and requires the user to authenticate again. The default is for the entries to remain permanently. We recommend that this value equal the idle timeout set for the WAN connection.

access-template

To manually place a temporary access list entry on a router to which you are connected, use the access-template EXEC command.

access-template [access-list-number | name] [dynamic-name] [source] [destination] [timeout minutes]

Syntax Description

access-list-number

(Optional) Number of the dynamic access list.

name

(Optional) Name of an IP access list. The name cannot contain a space or quotation mark and must begin with an alphabetic character to avoid ambiguity with numbered access lists.

dynamic-name

(Optional) Name of a dynamic access list.

source

(Optional) Source address in a dynamic access list. The keywords host and any are allowed. All other attributes are inherited from the original access-list entry.

destination

(Optional) Destination address in a dynamic access list. The keywords host and any are allowed. All other attributes are inherited from the original access-list entry.

timeout minutes

(Optional) Specifies a maximum time limit for each entry within this dynamic list. This is an absolute time, from creation, that an entry can reside in the list. The default is an infinite time limit and allows an entry to remain permanently.
