Ports blocked when moving LACP connection to new switches

Ports blocked when moving LACP connection to new switches

We currently both connections from our ISP connected to one X460-48t switch (16.2.5.4 16.2.5.4-patch1-30)

Ports are set to auto-negotiate.

We are attempting to move the connections to two Extreme Networks x695 switches (31.7.1.4-patch1-36).

We can’t set the ports to auto-negotiate ("01/06/2024 07:35:24.10 <Warn:HAL.Port.OpticCfgCflct> The configuration for the LX optic module is not correct - please configure port 36 for auto-negotiation Off and speed 1000”), so they have to be manually configured.

Switch #1
configure ports 36 auto off speed 1000 duplex full
enable sharing 36 grouping 36 algorithm address-based L2 lacp
enable mlag port 36 peer x695-02 id 36



Switch #2
configure ports 36 auto off speed 1000 duplex full
enable sharing 36 grouping 36 algorithm address-based L2 lacp
enable mlag port 36 peer x695-01 id 36

However, when we move the cables to the new switches, XOS is disabling the ports.  We don't have spanning tree enabled, so that isn't the issue.  I opened a case and the best guess is because the ISP portal is set to auto-negotiation on the ports whereas we have them set to manual.  We won't be able to test changing the ISP portal settings to auto-negotiation off until 2/3, but has anyone run into an issue where a mismatch of auto-negotiation blocks ports?

Tried this again today, and the reason for the ports being blocked really was the fact that they were set to auto-negotiate on in the ISP control panel and auto-negotiate off on the ports.  Switching the ISP to auto off resolved the blocking.

Thanks for the reply.  Yes, the port on both switches was showing a link but blocked (below).  We will try hard setting the speed.
