Configuring the Number of Leases for the Address Pool

The number of lease IP addresses used for the DHCP address pool can be configured.

Memory is allocated based on the number of leases configured on the switch. The switch allocates the memory for the first 3000 leases. Any configured leases on the remaining address pools are then removed from the configuration.

Note: A maximum of 3000 leases can be configured. When 3000 leases are allocated, the configuration under any remaining pools is removed from the configuration.

Note: If more than 3000 leases are configured, the following error is displayed while rebooting: Error: exceeds maximum 3000 leases.

Note: After upgrading to FastIron 09.0.10a, it is recommended to re-configure the DHCP server address pool, and to configure the lease count with the number of leases specific to the address pool.

Complete the following steps to configure the number of lease IP addresses used for the DHCP address pool.

  1. Enter global configuration mode by issuing the configure terminal command. 
    device# configure terminal
  2. Create and enter DHCP server pool configuration mode. 
    device(config)# ip dhcp-server pool cabo
  3. Configure the number of lease IP addresses. 
    device(config-dhcp-cabo)# lease-count 2500

The following example sets the number of lease IP addresses used for the DHCP address pool to 2500. 

device# configure terminal
device(config)# ip dhcp-server-pool cabo
device(config-dhcp-cabo)# lease-count 2500
