mac_address:
|
|
description:
|
|
- Specifies the floating Media Access Control (MAC) address associated with the floating IP addresses
|
|
defined for a traffic group.
|
|
- Primarily, a MAC masquerade address minimizes ARP communications or dropped packets as a result of failover.
|
|
- A MAC masquerade address ensures that any traffic destined for a specific traffic group reaches an available
|
|
device after failover, which happens because along with the traffic group, the MAC masquerade address floats
|
|
to the available device.
|
|
- Without a MAC masquerade address, the sending host must learn the MAC address for a newly-active device,
|
|
either by sending an ARP request or by relying on the gratuitous ARP from the newly-active device.
|
|
- To unset the MAC address, specify an empty value (C("")) to this parameter.
