ICX 7250 Queued Packets

[TannerW]

I'm having issues with speeds and have been doing further troubleshooting. The uplink from my 7250 is going to an OLT(Zhone) and is set to 10g. However, when I look at the port I have a ton of queued packets and no dropped packets. Will having tons of queued packets cause a slowdown in speeds or congestion in the network?

Hey @TannerW 

Queued packets are normal and expected for a store and forward switch/router. There is nothing to be concerned about there. If you start to see the Dropped Packets increment, then the egress buffer has overflowed for that specific queue. Hope this helps!
