Connectivity Guide

Address lease time
Use the lease {days [hours] [minutes] | infinite} command to congure an address lease time (default 24 hours).
OS10(config)# ip dhcp server
OS10(conf-dhcp)# pool Dell
OS10(conf-dhcp-Dell)# lease 36
Default gateway
Ensure the IP address of the default router is on the same subnet as the client.
1 Enable DHCP server-assigned dynamic addresses on an interface in CONFIGURATION mode.
ip dhcp server
2 Create an IP address pool and provide a name in DHCP mode.
pool name
3 Enter the default gateway(s) for the clients on the subnet in order of preference in DHCP<POOL> mode.
default-router address
Change default gateway name
OS10(config)# ip dhcp server
OS10(conf-dhcp)# pool Dell
OS10(conf-dhcp-Dell)# default-router 20.1.1.1
Enable DHCP server
Use the ip dhcp server command to enable DHCP server-assigned dynamic addresses on an interface in CONFIGURATION mode.
The DHCP server is disabled by default.
OS10(config)# ip dhcp server
OS10(conf-dhcp)# no disable
Hostname resolution
You have two choices for hostname resolution — domain name server (DNS) or NetBIOS Windows internet naming service (WINS). Both
DHCP and WINS clients query IP servers to compare host names to IP addresses.
1 Enable DHCP server-assigned dynamic addresses on an interface in DHCP <POOL> mode.
ip dhcp server
2 Create in IP address pool and enter the name in DHCP mode.
pool name
3 Create a domain and enter the domain name in DHCP <POOL> mode.
domain-name name
4 Enter the DNS servers in order of preference that are available to a DHCP client in DHCP <POOL> mode.
dns-server address
DNS address resolution
OS10(config)# ip dhcp server
OS10(conf-dhcp)# pool Dell
OS10(conf-dhcp-Dell)# domain-name dell.com
OS10(conf-dhcp-Dell)# dns-server 192.168.1.1
