Output drops on cisco link connecting to F5 LTM mgmt port

On a connection like below:

 

 

Cisco 6509: gi x/y <<-->> F5 LTM: mgmt

 

 

I observed incrementing packet drops on the F5 LTM mgmt interface. Also, at the Cisco end, incrementing

 

output drops were observed.

 

 

tcpdump on the etho show brodcast packets including the HSRP hellos. My assumption is that the F5 LTM will

 

reject any packets it can't understand (including the cdp, hsrp and other broadcast), and this will cause the

 

pckt drop counter on mgmt port to increase.

 

 

Will this cause the output drop counter at the cisco device to roll up?

 

 

Any idea or suggestion is highly appreciated.
