packet loss to SW mgmt IP

[LRL]

This is a weird one. As usually we setup our sites with a local mgmt bridge and give a site a /27 for management of local devices. 10.247.33.224/27 to be pressie in this case. The subnet is as follows:

10.247.33.225 router
10.247.33.231 SW1 Uplink to router on routers ether5 and SWPort14
10.247.33.232 SW2 Uplink to router on routers ether8 and SWPort5
10.247.33.254 UBNT Gen3 Cam on SW2 Port4

From the router I see packet loss to SW2's IP, but from the router I see no packet loss to the camera which has to traverse the same interface.

From the camera I don't see packet loss to SW2's IP, but I'll have multiple pings in a row that come back between 700-3400ms

Web UI frequently cycles with "loss connection".

All of this was persistent prior to upgrade so I upgraded still no change so I did a cold reload and still the same. I'm going to try physically power cycling the switch, but I may replace it since it's 2 hours from here.

What model?

What firmware version? (I hope v1.5.0)

If this is a WS-12 unit then your going into SFP modules?

The Ports TAB allows you to set Speed/Duplex with the newer firmware.
Some SFP modules like Auto especially copper SFP modules, other like 1G.
Also make sure speed/duplex matches on the routers side.

Could also be bad SFP modules if this is a WS-12 model.

That appears to have been the culprit. I pulled them and re-seated and poof problem solved. I went ahead and changed them out to be sure.
