Deactivating crypto lists to modify IPSec VPN parameters

Most IPSec VPN parameters cannot be modified if they are linked to an active crypto list. To
modify a parameter linked to an active crypto list, you must first deactivate the list using the
no ip crypto-group command in the context of the interface on which the crypto list is
activated.
Note:
If the crypto list is activated on more than one interface, deactivate the crypto list
Note:
for each of the interfaces on which it is activated.
For example:
G350-001# interface Serial 2/1
G350-001(if: Serial 2/1)# no ip crypto-group
Done!
After modifying IPSec VPN parameters as desired, re-activate the crypto list on the interface
using the ip crypto-group crypto-list-id command. For example:
G350-001# interface Serial 2/1
G350-001(if: Serial 2/1)# ip crypto-group 901
Done!
Tip:
If you wish to change the parameters of a crypto-list, you can use the ip
Tip:
policy-list-copy <old list> <new list> command, edit the new list,
and activate it on the interface. Note that activating the new list will cause all the
current IPSec tunnels to close.
