Release M.10.35 Enhancements

An example of the ip source binding command is shown here:

ProCurve(config)# ip source binding 0030c1-7f49c0 interface vlan 100 10.10.20.1 interface A4

Note that the ip source binding command is the same command used by the Dynamic IP Lockdown feature to configure static bindings. The Dynamic ARP Protection and Dynamic IP Lockdown features share a common list of source IP-to-MAC bindings.

Configuring Additional Validation Checks on ARP Packets

Dynamic ARP protection can be configured to perform additional validation checks on ARP packets. By default, no additional checks are performed. To configure additional validation checks, enter the arp protect validate command at the global configuration level.

Syntax: [no] arp protect validate <[src-mac] [dst-mac] [ip]>

src-mac(Optional) Drops any ARP request or response packet in which the source MAC address in the Ethernet header does not match the sender MAC address in the body of the ARP packet.

dst-mac(Optional) Drops any unicast ARP response packet

 

in which the destination MAC address in the

 

Ethernet header does not mach the target MAC

 

address in the body of the ARP packet.

ip

(Optional) Drops any ARP packet in which the

 

sender IP address is invalid. Drops any ARP

 

response packet in which the target IP address is

 

invalid. Invalid IP addresses include: 0.0.0.0,

 

255.255.255.255, all IP multicast addresses, and

 

all Class E IP addresses.

You can configure one or more of the validation checks. The following example of the arp protect validate command shows how to configure the validation checks for source MAC address and destination AMC address:

ProCurve(config)# arp protect validate src-mac dst-mac
