SFP incompatibility on Netgate XG-7100

stephenw10

Were you able to get any further info on this?

Digging a bit it doesn't look like your boards are affected by that issue.

What does the ifconfig output from the other SFP module look like?

Are you able to test those modules direct to your switch?

I assume the switch shows it linked at 1G to Verizon when it's connected that way?

@stephenw10 Not yet, I am working with support on this. With the fiber connected it shows:
media: Ethernet autoselect (Unknown <rxpause,txpause>)
status: active
supported media:
media autoselect

with the fiber disconnected it shows:
media: Ethernet autoselect
status: no carrier
supported media:
media autoselect

There doesn't seem to be traffic passing through when connected. The SFP functions fine in a D-Link DGS-3630 managed switch

The generic SFP module also shows similar ifconfig verbose output?

@stephenw10 that was the output of the generic SFP (IC INTRACOM PN: 506724). This was with two of those linked together.

I bought a few other SFPs from fs.com so I can try the same test with those SFPs and see if anything changes. I'll post after I run the tests.

Same failure with the following SFPs:

vendor: CISCO-ADDON PN: GLC-LX-SM-RGD-AO SN: XXXXXX DATE: 2018-08-07
module temperature: 23.93 C Voltage: 3.29 Volts
RX: 0.20 mW (-6.91 dBm) TX: 0.24 mW (-6.07 dBm)

vendor: IC INTRACOM PN: 506724 SN: XXXXXX DATE: 2018-02-08
module temperature: 18.00 C Voltage: 3.24 Volts
RX: 0.21 mW (-6.60 dBm) TX: 0.31 mW (-5.00 dBm)

vendor: FS PN: SFP1G-SX-31 SN: XXXXXX DATE: 2018-11-09
module temperature: 22.05 C Voltage: 3.24 Volts
RX: 0.24 mW (-6.10 dBm) TX: 0.26 mW (-5.76 dBm)

vendor: FS PN: SFP1G-SX-31 SN: XXXXXX DATE: 2019-02-19
module temperature: 14.73 C Voltage: 3.30 Volts
RX: 0.31 mW (-4.96 dBm) TX: 0.23 mW (-6.26 dBm)

vendor: FS PN: SFP1G-LX-31 SN: XXXXXX DATE: 2018-06-29
module temperature: 21.85 C Voltage: 3.31 Volts
RX: 0.24 mW (-6.17 dBm) TX: 0.25 mW (-5.97 dBm)

There is RX and TX power so you know that there is handshaking but for some reason FreeBSD / pfSense just cannot make use of it. I know the SFP isn't faulty since I am using the same fiber / SFP in my switch to act as a media converter until support can help me fix this. The CISCO-ADDON SFP functions whether it is in a SFP or SFP+ port so I don't think this is a case of a SFP speed issue.

stephenw10

And by the same failure you mean they all show:

media: Ethernet autoselect (Unknown <rxpause,txpause>)
status: active

And seemingly pass no traffic?

Steve

WillCT1

Correct. I also might have had the "unsupported SFP" flag set incorrectly so I changed my loader.conf.local to:

hw.ixgbe.unsupported_sfp=1
hw.ix.unsupported_sfp=1

I also put those same items in the system tunables.

The output of the ifconfig was the same and I still cannot ping the gateway or any other IP that goes through that interface.

stephenw10

I doubt that was an issue, it's very rare that does anything.

If you do get an unsupported module you will find the interface disappears entirely if you boot with it in. The driver will fail to attach and you would see that reported in the boot log.

@WillCT1 Did you find resolution to this? Think I'm having the exact same issue.

WillCT1

@jake Not really. I ended up returning it as we couldn't get the XG-7100 to work with the SFP. The XG-7100 had a few quirks due to the internal switch but that shouldn't have made the SFP not work. All the other units I had from Netgate (different models) worked extremely well. The few issues I did have were fixed quickly and directly. I did purchase a media convertor for the SFP to 1G-BaseT as a potential workaround but didn't end up using it.
