ICX Brocade switch forwarding LLDP packet

unknown

Hello,

I'm working a hybrid-vendor network. Here is how it is all connected:

Cisco 4500 -> Brocade 7450 -> Brocade 7250 -> HP 2920 

Situation:
The funny thing is that on the uplink port of the HP switch (port 24) I'm seeing the Cisco 4500 LLDP info. By standard, it shouldn't really be there. It's 2 hops too far to show that data.

My question is: does Brocade implement any sort of LLDP packet forward mechanism? If it does, can it be limited to only 1 switch?

If LLDP is off on the ICXs, we will likely forward/flood LLDP like any other packet. If LLDP is on (lldp run globally), we will trap it to the cpu and it will not be forwarded. Do you have LLDP on for the two ICXs?
