NP7 hardware logging supports multicast logging

You can now configure NP7 hardware logging to support multicast logging. Previous hyperscale firewall versions of FortiOS only supported multicast logging for CPU or host logging.

You can use multicast logging to simultaneously send session setup log messages for CPU or software sessions to multiple remote syslog or NetFlow servers. Multicast logging is not supported for NP7 sessions.

Enable multicast logging by creating a log server group that contains two or more remote log servers and then set log-tx-mode to multicast:

config log npu-server

set log-processor hardware

config server-group

edit "log_ipv4_server1"

set log-format {netflow | syslog}

set log-tx-mode multicast

end

Set log-tx-mode to multicast to simultaneously send session setup log messages to multiple remote syslog or NetFlow servers.
