Page 313 from the training manual:

- Restart the service:

orchd restart

- Restart the service without confirmation

service orchd restart

This configuration likely provides balanced and redundant connectivity for orchestrator redundancy.

The Pre-Upgrade Verifier is a tool that checks the compatibility and readiness of the Maestro environment for the upgrade process. It verifies the current version, the target version, the hardware requirements, the configuration settings, and the license validity of the Maestro Orchestrators and the Security Groups. It also identifies any potential issues or risks that might affect the upgrade and provides recommendations on how to resolve them. The Pre-Upgrade Verifier should be run before importing the R81.10 software package and before performing the actual upgrade.

Auto-topology is the default distribution mode for Maestro Security Groups. In this mode, the Orchestrator assigns packets to a Security Group Member based on the topology of the port defined in the gateway object. Each port is either in user mode or network mode depending on the topology. User mode means that the port is connected to the internal network and network mode means that the port is connected to the external network. The Orchestrator uses a hash function to map each source IP or destination IP to a specific SGM, depending on the mode of the port. This mode ensures that all packets with the same source IP or destination IP are processed by the same SGM, regardless of the port or protocol.

This aligns with the principle of redundancy in network systems, where the next available device with the lowest ID typically takes over management roles in case of a failure.

The Correction Layer is a Maestro component that ensures that packets from the same connection are handled by the same Security Group Module (SGM) in a multi-appliance system. This is especially important when NAT is involved, as packets sent from the client to the server can be distributed to a different SGM than packets from the same session sent from the server to the client. The Correction Layer must then forward the packet to the correct SGM.

The g_all prefix is used to run commands globally in Expert mode on all Security Group Members of the current Security Group. For example, g_all cpstop will stop the Check Point services on all SGMs. The other prefixes are not valid for global commands in Expert mode.

Security groups are used to simplify management and policy enforcement across multiple devices or network segments, often offering redundancy and load balancing features

The RJ-45 connectors located at the front panel of the Orchestrator MHO-170 are used for out-of-band management and serial console access. One of them is a 1Gbps RJ-45 port that provides an out-of-band interface for accessing the Orchestrator itself for configuration and management purposes. The other one is a RJ-45 serial console port that provides a command-line interface for initial setup and troubleshooting.

Network mode is the distribution mode that assigns packets to an SGM based solely on the packet destination IP. In this mode, the Orchestrator uses a hash function to map each destination IP to a specific SGM. This mode ensures that all packets with the same destination IP are processed by the same SGM, regardless of the source IP or port. This mode is suitable for scenarios where the destination IP is the main factor for load balancing, such as NAT or VPN.

The SMO Master is the SGM that is responsible for synchronizing the configuration and policy with the other SGMs in the security group. The SMO Master is automatically designated as the SGM with the lowest member ID, which is usually the first one added to the security group. The SMO Master can be changed manually if needed.

In a Maestro Dual Site environment, there are two sites that can host Security Group Members (SGMs) for each Security Group (SG). The Active Site is the one that is currently processing the traffic for a specific SG, while the Standby Site is the one that is ready to take over in case of a failover. The Active Site and the Standby Site can be different for different SGs, depending on the load balancing and failover policies. The Active Site and the Standby Site are synchronized by the Maestro Orchestrators (MHOs) using the Site-Sync port and VLANs.

Orchestrators in many network environments do not require separate licenses, as they primarily function to manage and distribute network traffic.

MHOs process traffic in Active-Active mode, which means that both MHOs are active and share the load of the traffic that is sent to and from the SGMs. Active-Active mode provides better performance and scalability than Active-Standby mode, which only uses one MHO at a time and keeps the other as a backup. Active-Active mode also allows for faster failover and recovery in case of an MHO failure, as the surviving MHO can take over the traffic without interruption.

The g_update_conf_file command is a global command that allows users to update the specified file on all Security Group Members of the current Security Group. The command takes the file name and the parameter-value pair as arguments and updates the file accordingly. For example, g_update_conf_file fwkern.conf fwha_enable_arp=1 will add or modify the fwha_enable_arp parameter in the fwkern.conf file on all SGMs.

According to the Port Mapping for the Check Point Maestro HyperScale Orchestrator MHO-175 document1, ports 1 - 4 are Management ports that are used to connect the MHO to the customer’s management infrastructure, such as SmartConsole or SmartDomain Manager. Ports 5 - 26 are Uplink ports that are used to connect the MHO to the customer’s network infrastructure, such as switches, routers, or firewalls. Ports 27 - 47 are Downlink ports that are used to connect the MHO to the Security Group Modules (SGMs) in the Security Group. Ports 49 - 55 are Backplane ports that are used to connect the MHO to another MHO in a Dual Orchestrator environment.
