Redundancy protocol – RSTP
The Lynx switch support the Rapid Spanning Tree Protocol (RSTP) according to
IEEE802.1w with fallback to the Spanning Tree Protocol (STP - IEEE802.1D).
The STP fallback feature means that the Lynx switches can be used together
with switches that only have support for STP.
For more information on RSTP, please read the Whitepaper found on the enclosed Lynx CD
or at the Westermo website.
Available options are:
Bridge PrioThe switch with the lowest priority will become the root switch.
Dynamic Dynamic trunking is enabled when RSTP is used in a VLAN to
eliminate failure
Trunking due to an incorrectly configured VLAN. If every unit in the ring has
enabled Dynamic trunking, all VLANs will be granted access on the
ring.

on IGMP v1, IGMP v2 and IGMP v3. To enable IGMP Snooping, click Enable IGMP.
For more information on IGMP, please read the Whitepaper found on the enclosed Lynx CD
or at the Westermo website.
This unit will always act as a member in the network.
Auto mode disabled + Querier enabled:
This unit will always act as Querier in the network.
(IGMP focal point)
Auto mode enabled + Querier enabled:
This unit can act as a Querier in the network. If
more than one unit in the network is configured
with this setting, the unit with the lowest IP-address
will automatically be selected as Querier. If that
unit should fail, the unit with the second lowest
IP-address becomes the Querier, then the third lowest and so on.
Querier interval (seconds)Indicates the interval between two IGMP query
packets. Four intervals are possible. 12, 30, 70 or 150
seconds.
Enable IGMP Fast ReconnectThe IP multicast filter implementation is integrated
with the Fast Reconfiguration of Network Topology
(FRNT) protocol. This means that the multicast
filters will be updated as fast the FRNT implementation handles a topology change, i.e. approx. 20 ms.
Trunk PortsThe IGMP Queriers will be forwarded on selected
ports.
Click the "Apply" button to confirm changes made to the IGMP settings.

MAC Filter
If the MAC filter is enabled, only approved MAC addresses will be granted access through
the switch. To approve MAC addresses, add them according to the methods below.
Note that this function should be used with care. An incorrect configuration
could result in total denied access, and a factory reset of the unit would then
be needed.
MAC addresses can be added to the MAC filter by different methods:
1) One by one by adding a single MAC address in the small input-box.
The MAC address should be typed in the standard format - e.g. 00:07:7c:12:34:56
2) As a range of addresses using an asterisk, *, as a wild card. E.g. 00:07:7c:12:34:**
This will allow addresses between 00:07:7c:12:34:00 to 00:07:7c:12:34:ff.
3) As a sequence of single MAC addresses divided by a semi colon.
Example: 00:07:7c:00:00:00;00:07:7c:00:01:00;00:07:7c:00:0*:**;00:07:7c:00:00:02;
MAC addresses can be added according to method 1 and method 2 in the sequence.
Available options are:
