Managing Subnets

Subnets control settings for each subnet that DHCP serves. A subnet can include a range of IP addresses to
give clients. Subnets contain groups, pools and hosts. Only one subnet can contain dynamic IP address ranges
without any access restrictions on any given physical port, since DHCP doesn't know which subnet a client
should belong to when the request is received.
The following sections describe how to configure and manage subnets on a DHCP server:
• Section 5.15.7.1, "Viewing a List of Subnets"
• Section 5.15.7.2, "Adding a Subnet"
• Section 5.15.7.3, "Configuring Subnet Options"
• Section 5.15.7.4, "Configuring a Subnet Client"
• Section 5.15.7.5, "Deleting a Subnet"
Section 5.15.7.1

Viewing a List of Subnets

To view a list of subnets, type:
show running-config services dhcpserver subnet
If subnets have been configured, a table or list similar to the following example appears:
ruggedcom# show running-config services dhcpserver subnet network-ip | tab
NAME NETWORK IP
-----------------------
SUB1 192.168.0.0/27
