HA Interface
- Network > Interfaces > Ethernet
Each high availability (HA) interface has a specific function:
one interface is for configuration synchronization and heartbeats,
and the other interface is for state synchronization. If active/active
high availability is enabled, the firewall can use a third HA interface
to forward packets.
Some Palo Alto Networks firewalls include dedicated physical ports
for use in HA deployments (one for the control link and one for
the data link). For firewalls that do not include dedicated ports,
you must specify the data ports that will be used for HA. For additional
information on HA, refer to “Device > Virtual Systems”.
To configure an HA interface, click the name of an Interface
(ethernet1/1, for example) that is not configured and specify the
following information.
HA Interface Settings | Configured In | Description |
---|---|---|
Interface Name | Ethernet Interface | The interface name is predefined and you
cannot change it. |
Comment | Enter an optional description for the interface. | |
Interface Type | Select HA . | |
Link Speed | Ethernet Interface Advanced Link Settings | Select the interface speed in Mbps, or select auto to
have the firewall automatically determine the speed. |
Link Duplex | Select whether the interface transmission
mode is full-duplex ( full ), half-duplex (half ),
or negotiated automatically (auto ). | |
Link State | Select whether the interface
status is enabled ( up ), disabled (down ),
or determined automatically (auto ). | |
PoE Rsvd Pwr | Ethernet Interface Advanced PoE Settings ( Supported firewalls only ) | Select the amount of allocated
power in Watts if PoE is enabled. |
PoE Enable | Select to enable PoE on this interface. When using Panorama, non-PoE
interfaces display the option to enable or disable PoE. To avoid a
commit failure, ensure that PoE Enable
remains selected on these non-PoE interfaces. |
