This example shows that the preassigned address was correctly reserved in the DHCP pool:
switch# show ip dhcp pool dhcppool
Pool dhcp pool:
Utilization mark (high/low) : 100 / 0
Subnet size (first/next) : 0 / 0
Total addresses : 254
Leased addresses : 0
Excluded addresses : 4
Pending event : none
1 subnet is currently in the pool:
Current index
10.1.1.1
1 reserved address is currently in the pool
Address
10.1.1.7 Et1/0
Enabling DHCP Snooping: Example
This example shows how to enable DHCP snooping globally and on VLAN 10 and to configure a rate limit of 100 packets
per second on a port:
Switch(config)# ip dhcp snooping
Switch(config)# ip dhcp snooping vlan 10
Switch(config)# ip dhcp snooping information option
Switch(config)# interface GigabitEthernet1/17
Switch(config-if)# ip dhcp snooping limit rate 100
