Multicast Storm Protection
Multicast storm protection is enabled for the same reason as broadcast storm protection. IP phones and some industrial
networks such as EtherNet/IP generate significant multicast traffic.
Port Mirroring
Port mirroring is an advanced switch feature disabled by default. To use this feature, you must add the key SnifferPort to
the setup file. The configured port will mirror all packets received and transmitted on port 3 (internal switch connection to
RMA PLUS). Connect a PC running
on the sniffer port to capture all traffic seen by the RMA PLUS.
MAC Filter
The RMA PLUS implements unicast Source Address (SA) filtering. If configured, it will filter out all MACs except those
configured in the acceptance filters MACA(1-3) . Use MAC filtering to add a layer of anonymity to your network.

Ethernet
MAC fil-
tering
MAC address(es) for Ethernet MAC filtering. Each MAC address is a string con-
sisting of six hexadecimal octets separated by a colon. The MAC will only allow
requests from the MAC addresses specified in this file. These records are not mem-
bers of the default file, and therefore, the feature is disabled. If you wish to use this
feature, you must add one or more records to the setup file.
Setup Key: MACA 1-3
Addressing
The RMA PLUS currently implements IPV4 static and DHCP addressing. Static addressing is the preferred method.
If DHCP is selected and the device does not get an address from the server, the RMA PLUS will fail to the static IP
address after a timeout period.
NetBIOS Name Service
The RMA PLUS implements NetBIOS-NS. This means the RMA PLUS may be addressed by its IP address or
NetBIOS / host name. The format of the NetBIOS name is RMA-<Serial Number>. Ensure that NetBIOS is enabled in
the network adapter settings for this feature to work. Example: RMA-1894854 (where 1894854 is the device serial num-
ber)
Intermodule Bus Over Ethernet
Software tools use this feature to discover Watlow devices on an Ethernet network. The RMA PLUS provides up to
three (priority based) intermodule bus Ethernet gateway sessions. Each connection provides access to the RMA PLUS
and all devices connected to the intermodule bus network. Transactions intended for remote devices are proxied
(routed) through the RMA PLUS.
The keep-alive feature is enabled on all accepted sockets. This prevents socket leaks if a socket is not closed properly.
Typical causes include application hang / crash, loss of link, severed network, half close, etc.
This service is enabled by default for all model numbers. It may be disabled by writing “No” on the "Watbus Enable"
member. If you disable discovery, you must specify the IP address or host name to make a connection with PC soft-
ware. NOTE: A reset is required for this change to take effect.
