Odd Network Speed display

[ijuarez]

I was doing some cleaning up on my unraid server 6.1.3 and notice in the dashboard that my eth0 was reporting 100/full not 1000.

 

My board is a gigabyte with a realtek nic, and i have been reading the other post about some goofy anomalies. Everything in my network is gigabit so I Know that is not the issue.

 

I did a quick "ifconfig"

and sure enough is reporting a gig i wonder why unraid states it is not, prior to the latest update it did say 1000full.

 

eth0: flags=4419<UP,BROADCAST,RUNNING,PROMISC,MULTICAST>  mtu 1500

        ether 50:e5:49:57:3c:1e  txqueuelen 1000  (Ethernet)

        RX packets 148296302  bytes 198267741123 (184.6 GiB)

        RX errors 0  dropped 0  overruns 0  frame 0

        TX packets 91167762  bytes 30310912674 (28.2 GiB)

        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

 

Just thought i asked, performance does not seem to be hampered.

You might want to check your cabling, since the speed is negotiated down to 100 Mb/s.

I will,

its running cat6 , but that command gives me more details.

I will make sure that i didnt  pooch something.

It is always worth trying an alternative cable as if any of the connections inside a cat6 cable are defective then speed will be negotiated down to 100Mb (as that requires less connections).

Thank you guys for the suggestions but I found the culprit. My pfSense box has two added nics and they are only 10/100. They are connected to my asus rt n66u (only used for wifi) which i used the ports as a switch (they are Gigbit) however when i connected my firewall box it slowed the whole switch. I did have gig card in my previous box but they turn out not to be supported by pfsense.  Sooooo unraid is working perfectly.
