LACP Based aggregate interface status is "down" on an HA "suspended" device with LACP pre-negotiation enabled.

• LACP pre-negotiation is enabled.
• HA state of the device is "suspended".
• LACP based aggregate interface status is "down"

• Palo Alto Firewalls
• Supported PAN-OS
• High Availability Active/Passive
• LACP pre-negotiation enabled.
• Device is in HA "suspended" state.

• As described in "LACP and LLDP Pre-Negotiation for Active/Passive HA ", LACP pre-negotiation will pre-negotiate LACP in HA passive or Non-Functional state.
• As the device is in HA “Suspended” state, Firewall will not exchange LACP BPDU and LACP port will be in “Down” state.

1. Move the device to HA functional state for firewall to move to HA "Passive" state and negotiate LACP.
2. Refer How to recover HA pair member  to make HA device functional.
