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-name argument 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.
