Certain configuration changes will only take effect when negotiating subsequent security associations. 
If you want the new settings to take immediate effect, you must clear the existing security associations 
so that they will be reestablished with the changed configuration. If the switch is actively processing 
IPsec traffic, it is desirable to clear only the portion of the security association database that would be 
affected by the configuration changes (that is, clear only the security associations established by a given 
crypto map set). Clearing the full security association database should be reserved for large-scale 
changes, or when the router is processing very little other IPsec traffic.
