Mixing 1G and 100FD interfaces in same subnet for MC/SG

We are facing a linkloop failure ( result of cmquerycl) for nodes in a cluster. Nodes have mix of 1G and 100FD interfaces connected to same subnet. Linkloop fails between 100FD and 1G interfaces ? Any ideas ?

I do not believe HP-UX supports in any context Service Guard or not two NIC cards with the same network and subnet.

So these are Gigabit and 100BaseT cards, yes?
are the connected via switches? or how are they interconnected?
If you are getting linkloop failures, there is no physical connection between them, which could be switch configuration.
Or by 100FD do you mean FDDI links?

Re: Mixing 1G and 100FD interfaces in same subnet for MC/SG

This was the configuration :

some nodes with 1G interfaces and rest with 100FD had linkloop failing. It was found that they were on the different blades on CSCO6513. This is could be bug/prob of the CSCO 6513 switch. The 1G blades ports dont work at layer 2 with blades with 100FD, though at IP level all were fine ( ping/telnet/rlogin etc).

So moved all the interfaces on the 1G blades on the swicth, after setting proper speed on the port, linkloop started working.
