Field Reference

Table B-19 Preshared Key Page

Element		Description
Key Specification
User Defined		Click to use a manually defined preshared key, then enter the
		required preshared key in the Key field.
Auto Generated		Click to allocate a random key to the participating peers. This
		ensures security because a different key is generated for every
		hub-spoke connection. Auto Generate is the default selection.
		Note The key is allocated during the first deployment to the
		devices and is used in all subsequent deployments to the
		same devices, until you select the Regenerate Key (Only in
		Next Deployment) check box.
Key Length		The required length of the preshared key to be automatically
		generated (maximum 127 characters).
Same Key for All Tunnels		Unavailable in a point-to-point VPN topology.
		Select this check box to use the same auto-generated key for all
		tunnels.
		If you do not select this check box, different keys are used for the
		tunnels, except in cases, such as DMVPN configuration, when
		different multipoint GRE interfaces in the same network must use
		the same preshared key.
