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.
device(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:
device(config)# ip dhcp-server mgmt
Syntax: [no] ip dhcp-server mgmt
Setting the wait time for ARP-ping response
At startup, the server reconciles the lease-binding database by sending an ARP-ping packet out to
every client. If there is no response to the ARP-ping packet within a set amount of time (set in seconds),
the server deletes the client from the lease-binding database. The minimum setting is 5 seconds and
the maximum is 30 seconds.
Syntax: ip dhcp-server arp-ping-timeout num
• num - The number of seconds to wait for a response to an ARP-ping packet.
NOTE
Do not alter the default value unless it is necessary. Increasing the value of this timer may increase the
time to get console access after a reboot.
Creating an address pool
The ip dhcp-server pool command puts you in pool configuration mode, and allows you to create an
address pool.
device(config)# ip dhcp-server pool
device(config-dhcp-name)# ip dhcp-server pool monterey
device(config-dhcp-monterey)#
These commands create an address pool named monterey.
Syntax: ip dhcp-server pool name
Configuration notes for creating an address pool
• If the DHCP server address is part of a configured DHCP address pool, you must exclude the DHCP
server address from the network pool. Refer to Specifying addresses to exclude from the address
pool on page 93.
• While in DHCP server pool configuration mode, the system will place the DHCP server pool in
pending mode and the DHCP server will not use the address pool to distribute information to clients.
To activate the pool, use the deploy command. Refer to
Deploying an address pool configuration to
the server on page 92.
