Anyone got any suggestions for this.
I have a linksys sr2024 Gb switch
Several things are plugged into this - all using cat 5e or cat 6 cables.
Some things are connecting with full Gb speed but the main firewall wont.
The machine has 3 intel nic's -
lspci | egrep -i ethernet 04:00.0 Ethernet controller: Intel Corporation 82573L Gigabit Ethernet Controller (rev 01) 05:04.0 Ethernet controller: Intel Corporation 82541PI Gigabit Ethernet Controller (rev 05) 05:05.0 Ethernet controller: Intel Corporation 82541PI Gigabit Ethernet Controller (rev 05)
The 82573 is on board and not used - the other 2 nic's are used - one for internal subnet and one for external.
The internet side is connected to a cisco 800 router (which I believe is 10/100 only .. tho I cudnt swear for sure)
The inside is connected to the SR2024 Gb switch.
Both nic's come up in 100 Mb/s - I rebooted the switch, and I plugged and unplugged the cables, I tried ethtool -r ethx a few times to no avail.
Did you try ethtool -s ethX speed 1000
Other machines on same switch are happily running at full gigabit speeds.
Nothing in logs suggests a problem
Is there a problem with multi nics of same brand where they need to run at diff speeds ? Or is this a quirk with some hardware somewhere ? Or ???
Appreciate any suggesions ... its getting tiring forcing renogiation!
thanks ...
