receive-time month

Function

The receive-time command makes a key act as a receive-key for the specified interval of time.

The undo receive-time command deletes the receive-time configuration.

By default, no receive-time is configured.

Format

receive-time month start-month to end-month

receive-time month { start-month } &<1-12>

Parameters

Parameter	Description	Value
start-month	Specifies the month of the year to be configured as the start receive month for the given key.	The value ranges from January to December. jan feb mar apr may jun jul aug sep oct nov dec
to	Acts as a separator.	-
end-month	Specifies the end receive month.	The value ranges from January to December. feb mar apr may jun jul aug sep oct nov dec The end month should be greater than the start month.

Usage Guidelines

Usage Scenario

Each keychain consists of multiple key IDs that are valid within different time periods and each key ID is configured with an authentication algorithm. When a key ID becomes valid, the corresponding authentication algorithm is used, ensuring the dynamic change of authentication algorithms. Configure different key IDs for packet sending and receiving to be valid within different time periods.

Implementation Procedure

There are two keychain validity modes:

Absolute time range: In this mode, keychains are valid within a certain period and are invalid out of the period.
Periodic time range: In this mode, keychains are valid periodically. After one period ends, keychains continue to be valid within next period.
The mode in which key IDs for packet receiving become valid must be identical with that configured for the keychain.

Precautions

Only one key ID is valid within a time period. In other words, the send time periods of different key-ids cannot overlap with each other.

Example

# Configure the receive time with the timing mode as yearly periodic.
