Configuring IP parameters – Layer 3 Switches
Removing DHCP leases
The clear ip dhcp-server binding command can be used to delete a specific lease, or all lease
entries from the lease binding database.
Brocade(config)# clear ip dhcp-server binding *
Syntax: clear ip dhcp-server binding [<address> | <*>]
• <address> - The IP address to be deleted
• <*> - Clears all IP addresses
Enabling DHCP Server
The ip dhcp-server enable command enables DHCP Server, which is disabled by default.
Syntax: [no] ip dhcp-server enable
The no version of this command disables DHCP Server.
Disabling DHCP Server on the management port
By default, when DHCP Server is enabled, it responds to DHCP client requests received on the
management port. If desired, you can prevent the response to DHCP client requests received on
the management port, by disabling DHCP Server support on the port. When disabled, DHCP client
requests that are received on the management port are silently discarded.
To disable DHCP Server on the management port, enter the following command at the global
configuration level of the CLI.
Brocade(config)# no ip dhcp-server mgmt
To re-enable DHCP Server on the management port after it has been disabled, enter the ip
dhcp-server mgmt command:
Brocade(config)# ip dhcp-server mgmt
Syntax: [no] ip dhcp-server mgmt
