In addition to our Comprehensive configuration report and our Devices and ports reports, for a site or factory acceptance test, an audit or during troubleshooting with the help of our unique software tool* and a special script, we can generate this last Microsoft Excel® document.
Moreover, in a Gigabit network – without competing a complete reflectometry – it provides status’s summary of all optical links in your network. The transmitted / received power and the corresponding attenuation is reported with a color status (green to red) for each links. The attenuations are calculated in dBm and mW (whatever the firmware version of the switch) and can even tell you if a conflict exist on the end to end SFP’s types (eg. when using a LX SFP on one end and a LH SFP on the other end).
It is a perfect tool to pinpoint the faulty optical links you have to clean or change after a real reflectometry (we can help you on that purpose too).
A great improvement: there is now a control between transmitted and received power against the intrinsic values of each SFP used. This is a good way to proactively control the aging of the SFPs and if the other side transmission is too low to be detected.
Latest addition: this report provides a comprehensive Ethernet addresses map on your entire network (associated with IP). You can now easily find on which port of which switch a specific device is connected (if you don’t have a reliable documentation).
These last report as always using Microsoft Excel format includes the following elements:
- IP of A device, A Port and A device name if the partner B is answering using LLDP
- IP of B device, B Port and B device name
- In the case of an optical link,
- A to B and B to A attenuation in mW,
- A to B and B to A attenuation in dBm with a background color depending the attenuation value: green is good, yellow = warning, red = high attenuation
In the latter case, you should check the type of SFP (LH and LH+ have a larger optical budget and color can be red but with a still acceptable attenuation for this type of SFP)
- Conformity control of both SFPs: OK or error in red background if the two do not match (eg. LX SFP with LH SFP)
- IP, Port and device name
- SFP’s type
- Support: Is the SFP supported by the device ( Yes or Not supported) ?
- Inside temperature of the SFP (usually 10 to 15° more than the inside temp of the device)
- Transmission in mW and dBm
- Reception in mW and dBm
- Optical link status as reported by the SFP : OK or Error
- NEW: Control of SFP’s aging and too high attenuation on the SFP side
- Warning in case the transmitted power is lower than the usual one of this type of SFP (FALSE in red if Ptx<Pavg)
- Warning in case the transmitted power is lower than the minimum of this type of SFP (FALSE if Ptx<Pmin)
- Calculation of deviation between the real transmitted power and the average power of the SFP
- Warning in case the received power is lower than the lowest acceptable threshold of this type of SFP (FALSE if Prx<Pmin)
- MAC address (taken from FDB – Forwarding Database – table & LLDP – Link Layer Discovery – table)
- IP address (if a match is found in the ARP table)
- Ports list where this mac address is seen amongst the switches (IP of the switch in the first row).
- If the port background is green, the device with this mac is 99% connected to this port of this switch (info given by the FDB table)
- If the port background is yellow, the information is given by the LLDP table and the port is quite certainly the one where the device is connected
- If the port background is grey, this port is known as a backbone port in the LLDP table (so connected to another switch)
- If the port background has no colour, the report tool is not able to give a status for this mac on this switch. The address is seen on the port, it is not a known backbone port but many addresses are connected to it (may be the device is behind a non manageable switch or behind a switch which is not part of the analysed ones).
- The learning mode of this device: F (FDB : Forwarding Database of the switch) / L (LLDP table of the switch) / A (ARP table)
- In the proposed sample,
- The device with the mac 00:15:99:47:59:c2 (IP 220.127.116.11) is located most probably on port 1/7 of the switch 192.168.6.240 (last column) as there are only one address learned on that port on the forwarding database of the switch and it is not a known backbone port.
- The port 1/2 of the switch 192.168.6.240 is a backbone port (many addresses learned on that port et reported as backbone port on the LLDP table).
- The device with the mac 00:0e:58:8b:2d:ce (IP 18.104.22.168) is most probably located on port 1/8 of the switch 192.168.6.240 as it is reported as such by the LLDP table of this switch. There may be many addresses on this port (in case they are connected to a unmanageable switch or a switch not included in the analysis)
- The device with mac ec:e5:55:3f:14:ee has the IP 192.168.6.235 (at the right to this MAC) and it is the internal address of a Hirschmann switch (port is —-) with IP192.168.6.235 (first line of the raw).
To generate this report, we have to be on your site to collect the necessary items (not provided by the usual Hirschmann™ tools).
* This tool is internally developed and enhanced based on configurations on which we operate. It is now running in the 3rd major release and it should integrate in a short time a better compatibility with the new MSP and RSP products line.
