Something wierd with mac address' that I cant explain on my i2600 Series F5 LTM HA
We have 2 F5 LTM i2600 series physical devices running v13.1.3.2.We have 4 X 1G interfaces and 2 X 10GBFiber interfaces.One of the 1GB interfaces is patched and is used for the Management IP.Both 10GBFiber interfaces are patched and used for our Internal and External vlan. The weird thing I cant explain is why my Internal & External Vlans are using the mac address of 2 of the 1GB ports that are not patched, respectively. FYI..These F5s have been in use for 18 months without issues. I attached a screenshot. The only reason I noticed this is because we were adding a VPN in our environment and were tracing the traffic from the F5 during troubleshooting.The networking team was seeing a mac address that I told them couldn't be because the port was not patched.When I started looking deeper, I found that they were right. So my question is why is the F5 using a mac address belonging to a disconnected Interface for another connected interface that has its own mac address? Can anyone explain this behavior.
