36.1.2 Distribution information to the client

The table below describes the types of information that the Switch can distribute to clients. Optional information is not distributed even if option numbers are specified on the Switch unless clients request optional information by submitting an option request list.

Table 36-2: List of information distributed to clients on the Switch
Information	Overview
IP address	IP address that can be used by a client
IP address lease time (optional)	Lease time for a distributed IP address. In the Switch, the lease time is determined based on the values of the default-lease-time and max-lease-time parameters and the request from the client. (Option No. 51)
Subnet mask	Subnet mask length indicating a network address specified in the configuration. (Option No:1)
Router (optional)	A list of the IP addresses of the routers on the subnet containing the target client. NetBIOS name servers are listed according to priority from highest to the lowest. One of the IP addresses in this list is used as the gateway address for the client. (Option No:3) If you do not specify this item in the configuration, the Switches do not distribute a list of router IP addresses to the client when the client requests a router IP address. However, the Switches insert the IP address set for the client in the router IP address field and distribute the information to the client.
DNS (optional)	A list of IP addresses of the domain name servers that a client can use. NetBIOS name servers are listed according to priority from highest to the lowest. (Option No:6)
Host name (optional)	Host name of the client determined by the server. The host name might be restricted by the local domain name. A host name is specified as a character string. (Option No:12)
Domain name (optional)	Domain name to be used when the IP address of the client is converted to an FQDN by the Domain Name System. (Option No:15)
NetBIOS over TCP/IP name server (optional)	A list of the IP addresses of the NetBIOS name servers (WINS servers) referenced by a client. NetBIOS name servers are listed according to priority from highest to the lowest. (Option No:44)
NetBIOS over TCP/IP node type (optional)	Node type of the NetBIOS over TCP/IP client (NetBIOS name resolution method). (Option No:46) Code 1: B-node (broadcast) Code 2: P-node (peer to peer; WINS only) Code 4: M-node (mixed; WINS is used when the IP address is not found by a broadcast) Code 8: H-node (hybrid; broadcasting is used when the IP address is not found by WINS)
