This LongDisplayString, up to 512 characters, is described as the remote IKE Identity for this crypto map entry (slot 1 of up to five), which can be a hostname or an IP address in 'a.b.c.d/w.x.y.z' CIDR-like form, defaulting to a /32 mask if none is given; IKE uses it to differentiate which remote end is connecting. An admin populates several remote-identity slots like this one when a single crypto map must accept dial-up or multi-peer connections from more than one distinguishable remote identity. For example, an admin supporting several roaming users might set slot 1 to '198.51.100.21/255.255.255.255' to recognize one specific remote host among several allowed identities.
