Motorola WS5100 manual Editing the Properties of an Existing Dhcp Pool, Lease Time, Ddhhmm, Domain

Switch Services 5-5

Lease Time	When a DHCP server allocates an address for a DHCP client, the client is assigned a lease,
(dd:hh:mm)	which expires after a designated interval defined by the administrator. The lease time is the
	number of seconds an IP address is reserved for re-connection after its last use. Using very
	short leases, DHCP can dynamically reconfigure networks in which there are more
	computers than there are available IP addresses. This is useful, for example, in education
	and customer environments where mobile-unit users change frequently. Use longer leases if
	there are fewer users.
Domain	Displays the domain name for the current interface.

5.2.1.1Editing the Properties of an Existing DHCP Pool

The properties of an existing pool can be modified to suit the changing needs of your network. To modify the properties of an existing pool:

1.Select Services > DHCP Server from the main menu tree.

The DHCP Server screen displays with the Configuration tab displayed.

2.Select an existing pool from those displayed within the Network Pool field and click the Edit button.

3.Modify the name of the IP pool from which IP addresses can be issued to client requests on this interface.

4.Modify the Domain name as appropriate for the interface using the pool.

5.Modify the NetBios Node used with this particular pool. The NetBios Node could have one of the following types:

•A b-broadcast(broadcast node) uses broadcasting to query nodes on the network for the owner of a NetBIOS name.

•A p-peer(peer-to-peer node) uses directed calls to communicate with a known NetBIOS name server, such as a Windows Internet Name Service (WINS) server, for the IP address of a NetBIOS
