Configuring The Dhcp Server's Ping Settings - HP ProCurve 7000dl Series Basic Management And Configuration Manual

2. Configure the VLAN interfaces:
ProCurve(config-eth 0/1)# interface eth 0/1.1
ProCurve(config-eth 0/1.1)# description Scope 1 interface
ProCurve(config-eth 0/1.1)# vlan-id 101
ProCurve(config-eth 0/1.1)# ip address 10.2.1.1 255.255.255.0
ProCurve(config-eth 0/1.1)# no shutdown
ProCurve(config-eth 0/1.1)# interface eth 0/1.2
ProCurve(config-eth 0/1.2)# description Scope 2 interface
ProCurve(config-eth 0/1.2)# vlan-id 102
ProCurve(config-eth 0/1.2)# ip address 10.3.1.1 255.255.255.0
ProCurve(config-eth 0/1.2)# no shutdown
3. Reserve addresses for the VLAN interfaces and other servers by excluding
them from DHCP:
ProCurve(config)# ip dhcp excluded-address 10.2.1.1 10.2.1.20
ProCurve(config)# ip dhcp excluded-address 10.3.1.1 10.3.1.20
4. Configure a DCHP pool for each VLAN, and set the IP address of the
default router to that of the corresponding VLAN interface:
ProCurve(config)# ip dhcp-server pool Scope1
ProCurve(config-dhcp-pool)# network 10.2.1.0 255.255.255.0
ProCurve(config-dhcp-pool)# default-router 10.2.1.1
ProCurve(config-dhcp-pool)# ip dhcp-server pool Scope2
ProCurve(config-dhcp-pool)# network 10.3.1.0 255.255.255.0
ProCurve(config-dhcp-pool)# default-router 10.3.1.1

Configuring the DHCP Server's Ping Settings

The DHCP server sends ping packets to verify that an address is available
before assigning it to a DHCP client. You can configure two settings for DHCP
server pings:
Timeout—This determines how long the DHCP server waits for a reply to
a ping.
Ping packet count—The DHCP server pings an address without result this
many times before assigning the address to a requesting client.
By default, the router times out a ping after 500 ms and pings an address twice
before assuming it is available.
Ping settings apply to DHCP on the router as a whole, not to individual DHCP
pools. You configure them from the global configuration mode context.
