Sending Event Messages to Log Targets

You can specify seven types of targets to receive log messages:

Console display
Current session (Telnet or console display)
Memory buffer (can contain 200 to 20,000 messages)
NVRAM (messages remain after reboot)
Primary node (for SummitStack)
Backup node (for SummitStack)
Syslog server, supports IPv6 address family as of ExtremeXOS 21.1

The first six targets exist by default; but before enabling any syslog host, you must add the host's information to the switch using the configure syslog command.

By default, the memory buffer and NVRAM targets are already enabled and receive messages.

To start sending messages to the targets, use the following command:
enable log target [console | memory-buffer | nvram | primary-node|backup-node| session | syslog [all | ipaddress udp-port {udp_port} | ipPort | ipaddress tls_port {tls_port}] {vr vr_name} {local0...local7}]]

After you enable this feature, the target receives the messages for which it is configured. See Target Configuration for information on viewing the current configuration of a target. The memory buffer can contain only the configured number of messages, so the oldest message is lost when a new message arrives, when the buffer is full.
To stop sending messages to the target, use the following command:
disable log target [console | memory-buffer | nvram |primary-node | backup-node | session | syslog [all | ipaddress udp-port {udp_port} | ipPort | ipaddress tls_port {tls_port}] {vr vr_name} {local0 ... local7}]]

Refer to your UNIX documentation for more information about the syslog host facility.
