Check optic information and data

Hi All,

One of our customers has two r4600 appliances and on those appliances is a BIP-IP tenant configured.
The two BIG-IP tenants are configured in a Device Group (Sync and Fail-Over).

Both appliances are in different data centers so customer is using a MRV solution to create connectivity between the data centers. This solution has been there for many years and is working fine when connecting their infrastructure.

Now we want to use the MRV solution to connect both r4600 appliances for config sync and network fail-over.

We have F5 SFP's in the r4600 appliances but when we connect them (on both sides) to the MRV hardware, there is no link. When we connect the r4600 appliance to a switch, we have link and the interface is UP.

Customer checked the MRV setup and the fiber path between the data centers and they seem to be OK. No other issues are reported with the link between the data centers.

As a work-around, we have configured ethernet ports to connect both r4600 appliance for sync and network fail-over and those ports are connected to access ports on a switch. But customer prefers to use the 10Gbe interfaces connected to the MRV solution.

How can we troubleshoot this on the F5 side? Are there commands to get optic data on a very low level to see what is going on? 

Any tips and tricks are welcome.

Regards,
Martijn
