Ethernet Port Speed for PGXL and TGXL

I am doing some cleanup on my network and noticed something interesting.

If I set the Ethernet port speed for my 6600 to 100MB/Full, everything works as expected.

If I set the Ethernet port speed for the TGXL and PGXL to 100MB/Full, I get an Ethernet link, but neither device can grab a DHCP address. If I change back to auto-negotiation, DHCP works fine.

When set to auto-negotiation, the TGXL and PGXL link up at 100MB/Full (according to the switch). It seems the devices have issues when a forced speed/duplex is set.

I have tried this with three switches, and the behavior is the same.

Is anyone else seeing this?

    I have seen that and I have passed it on to 4O3A.

    It could be that different networks and routers will give different results, so this may not help, but I found a simple solution here which was to set fixed IP addresses for my PGXL and TGXL.

    Along the same vein… my TGXL is connected to an in-shack Ubiquiti Gigabit managed switch. This switch has been a reliable workhorse for years. I have computers, a POE-phone, printer, Flex6400, Maestro C, and never a hiccup.

    My TGXL, when powered-up, will never get a DHCP address. After showing 0.0.0.0 for a short while, it self-assigns 169.x.x.x

    Once up though, if I unplug and replug the RJ-45 network connection, it will get a DHCP address.

    Annoying … so I set a static address, and it "just works" now.

    I run my TGXL on a 19V 2A supply.

    I found on my TGXL that it would not always get an IP address from my TP-LINK Gigabit switch. It would always work on a 100M switch.
