Parameter proposal-name&<1-6>: Name of the IPSec proposal for the IPSec policy to reference, a string of 1 to 15 characters. &<1-6> means that you can specify the proposal-nameargument for up to six times.

Description Use the proposal command to specify the IPSec proposal(s) for the IPSec policy to reference.

Use the undo proposal command to remove an IPSec proposal reference by the

IPSec policy.

By default, an IPSec policy references no IPSec proposal.

Note that:

■You can specify only existing IPSec proposals when using this command.

■A manual IPSec policy can reference only one IPSec proposal. To replace a referenced IPSec proposal, use the undo proposal command to remove the original proposal binding and then use the proposal command to reconfigure one.

■An IKE negotiated IPSec policy can reference up to six IPSec proposals. The IKE negotiation process will search for and use the exactly matched proposal.
