Multicast 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 | host}

config server-group

edit "log_ipv4_server1"

set log-format {netflow | syslog}

set log-tx-mode multicast

end

The following example shows how to set up two remote syslog servers and then add them to a log server group with multicast logging enabled.

config log npu-server

set log-processor {hardware | host}

config server-info

edit 1

set vdom "root"

set ipv4-server <server-ip>

set source-port 8055

set dest-port 2055

set template-tx-timeout 60

next

edit 2

set vdom "root"

set ipv4-server <server-ip>

set source-port 8055

set dest-port 2055

set template-tx-timeout 60

end

end

config server-group

edit "Example-Multicast"

set log-format syslog

set log-tx-mode multicast

set server-number 2

set server-start-id 1

end
