Chapter 30 Configuring Tunnel Groups, Group Policies, and Users
Configuring User Attributes
If, however, you specify the method as new-tunnel:
hostname(config-username-webvpn)# no svc rekey method new-tunnel
hostname(config-username-webvpn)#
and the current method is ssl, then the command fails, because the values don't match.
In the following example, the user configures the SVC to renegotiate with SSL during rekey and
configures the rekey to occur 30 minutes after the session begins:
hostname(config-username-webvpn)# svc rekey method ssl
hostname(config-username-webvpn)# svc rekey time 30
hostname(config-username-webvpn)#
