ICX 7250 Queued Packets

New Contributor

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!
