This INTEGER, isakmp or isakmpDialup, is described as indicating whether this crypto map is a regular map or used for dial-up, noting its value is set only at creation and must not be modified afterward. An admin picks 'isakmpDialup' for remote-access style connections from roaming or dial-in users, and plain 'isakmp' for fixed site-to-site tunnels, since choosing wrong at creation cannot be corrected in place. For example, an admin setting up VPN access for traveling employees would create the crypto map with this set to 'isakmpDialup', while a permanent branch-office tunnel would use 'isakmp'.
