Hello,

We have CRS328-24P-4S+ running Mikrotik version 7.10.2 we are getting Tx Drop anyone facing same issue?

Regards

Any Idea?

Sure...after you provide some additional information:

• what version were you running before?
• had the same problem with previous OS?
• what is the percentage drops in regards to the traffic?
• is it on an interface (and have you checked wire?
• what does your config look like?

what version were you running before?
-Before we was on v6.49.8 long term.
had the same problem with previous OS?
- Yes
what is the percentage drops in regards to the traffic?
Tx Unicast: 330541201
Tx Broadcast: 85454
Tx Multicast: 82283
Tx Drop: 448
is it on an interface (and have you checked wire?
Tested on both interfaces SFP and Ethernet
what does your config look like?

P.S.: Now We are downgraded the switch to v6.49.8 long term again, Ethernet 1 the main link we have very simple configuration on the switch it's just an access switch. We are getting more TX Drop when using queue=only-hardware-queue

Regards

I seem to be seeing this same thing but on a CRS326-24G.
Similar bridge setup and tx drops. Happening on 2 switches on the SFP+ interfaces. I do see some on copper interfaces as well, but not nearly as many as the SFP+ interfaces. 65 tx drops in under 30 min of runtime. No rx drops though, rx is running clean. Just seems to be tx.

Hello,

Any fix about above issue?

Tested v7.15.2 still have TX drops.

What is connected to the ports you are seeing drops in?

Out of curiosity I checked a CRS326-24G-2S+ that's in use as a server switch here and sure enough I am seeing TX drops however only on 4 interfaces. The devices connected to these 4 interfaces are all Proxmox servers.

All 4 ports are vlan trunks. As these are the only ports on the switch with TX drops I'm inclined to think it's a client issue rather than a switch issue and that Proxmox might be the issue.

I also have a CRS328-24P-4S+ and no ports are showing TX drops.

The CRS326 is running 7.15.2
The CRS328 is running 7.15.1

Hello,

Mikrotik PowerBox's with 100Mbps port are connected to ports.
