IP ADDRESSING AND PROTOCOL COMMANDS
ARP
-MAC-DISPARITY
arp-mac-disparity
Overview Use this command in Interface Configuration mode for a VLAN interface to enable
the reception of ARP packets that contain a multicast MAC address in the sender
field.
By default, ARP packets that contain a multicast MAC address in the sender field are
dropped. The no variant of this command reverts to the default behavior.
Syntax
arp-mac-disparity
no arp-mac-disparity
Default ARP disparity is disabled. ARP packets with a multicast MAC address in the sender
field are dropped.
Mode Interface Configuration for a VLAN interface.
Usage Normally, it is invalid for an ARP request to resolve a multicast MAC address. By
default, ARP replies with a multicast MAC addresses are not learned. This
command allows control over the learning of dynamic ARPs that resolve to a
multicast MAC address.
ARP-MAC disparity may need to be enabled to support multicast network load
balancing. The arp-mac-disparity command allows ARP replies quoting multicast
MAC addresses to be accepted and learned. No arp-mac-disparity command
reverts to default behavior.
If the ARP-MAC disparity feature is enabled, then the device sends traffic to a single
port as specified by the ARP entry.
Examples To enable ARP MAC disparity on interface vlan2, use the following commands:
awplus# configure terminal
awplus(config)# interface vlan2
awplus(config-if)# arp-mac-disparity
To disable ARP MAC disparity on interface vlan2, use the following commands:
awplus# configure terminal
awplus(config)# interface vlan2
awplus(config-if)# no arp-mac-disparity
