Is it possible for CFIP PhoeniX M to configure GigE ports capacity like standard Fast Ethernet module? Are the ports separated from each other, so that they can’t see each other’s traffic? What is the MTU for GigE module?

Is CFIP PhoeniX M switch transparent to QinQ VLANs? Is Rapid Spanning Tree Protocol (RSTP) and Multiple Spanning Tree Protocol (MSTP) supported?

Is there any limitations regarding GigE SFP (Small Form-factor Pluggable) module choice for CFIP PhoeniX M?

Does CFIP PhoeniX M utilize transparent transmission of BPDU frames or does there exist a possibility to set BPDU filtering off when STP is off?

In CFIP PhoeniX M link from A to B there is the following problem: on B side Tx output power is set to 24dBm but actual value is -3.8dBm. The ATPC is disabled. This problem never happened before and we had similar problem on another CFQ link, but after rebooting it works fine.

During the test of CFIP PhoeniX M link and using Iperf, I got only 53Mbps instead of 100Mbps. Why did it happen?

We would like to segregate the traffic on our CFIP PhoeniX M backbone into different VLANs so we keep the different traffic types separated. We would also like to have some of the ports as trunk or tagged ports so we can do some aggregation at that level. SAF CFQ IDU has 2xE1, 4 Gigabit Ethernet Interfaces, 2 Fast Ethernet interfaces for NMS.

We have never before configured space diversity CFIP PhoeniX M link. What are the correct steps to do? Currently we have defined link mode to be Protected Diversity with capacity setting ETH 100-28. After updating link, it is starting to establish a link. Soon we got one or two green lights to IF modem, but soon those are starting to blink yellow again. This behavior seems to be continuing forever. SNR seems to be quite low around 20 dBm even signal level is around -35 dBm. Is this because we are trying to do this on the table with all the radios close to each other? Should only one transmitter be active in space diversity? It looks like that both transmitters are active, but each using 5 dBm power instead of configured power.
