Heartbeat Backup - Uses the management ports on the HA devices to provide a backup path for heartbeat and hello messages. The management port IP address will be shared with the HA peer through the HA1 control link. No additional configuration is required.

What is HA in Palo Alto?

High availability (HA) is a deployment in which two firewalls are placed in a group and their configuration is synchronized to prevent a single point of failure on your network. A heartbeat connection between the firewall peers ensures seamless failover in the event that a peer goes down.

What does the HSCI port on a firewall do?

—The HSCI port is a Layer 1 SFP+ interface that connects two PA-3200 Series firewalls in an HA configuration. Use this port for an HA2 connection, HA3 connection, or both. The traffic carried on the HSCI ports is raw Layer 1 traffic, which is not routable or switchable.

Can a HA2 port be connected to a HSCI port?

For HA2 or HA2/HA3 traffic, the PA-7000 Series firewalls synchronize sessions across the NPCs one-for-one. —Connect the HSCI-B port on the first firewall directly to the HSCI-B port on the second firewall. HA2 and HA2-Backup links can be configured to use a dataplane interface instead of the HSCI ports.

Where are the HSCI ports on a Palo Alto firewall?

The HSCI ports must be connected directly between the two firewalls in the HA configuration (without a switch or router between them). When directly connecting the HSCI ports between two PA-3200 Series firewalls that are physically located near each other, Palo Alto Networks recommends that you use a passive SFP+ cable.

What does HSIC stand for in computer industry?
