Usage Guidelines
â—† Host addresses must fall within the range specified for an existing network
pool.
â—† When a client request is received, the switch first checks for a network address
pool matching the gateway where the request originated (i.e., if the request
was forwarded by a relay server). If there is no gateway in the client request (i.e.,
the request was not forwarded by a relay server), the switch searches for a
network pool matching the interface through which the client request was
received. It then searches for a manually configured host address that falls
within the matching network pool.
