3781.0. "DR900TM port sees a different address" by GIDDAY::STANISLAUS () Thu Aug 08 1996 06:25

    
    	Has anyone seen a problem with a DR900TM security setup.
    
    	Version 2.0.0. Don't know the version of the MAM module.
    	
    	A customer is telling me that he has setup security on a DR900TM so
    that for example port A2 can use the network only if's address is 
    08-00-2b-01-02-03. If not disable port. He tells me that about once
    every 2 to 3 days the port gets locked out (disabled) because it saw
    another address such as 08-00-2b-04-05-06. This address is not a
    phantom address but a real address that either sits on the Flex-Channel
    that the DR900TM is connected to.
    
    	I said to him to move the station above connected from port A2 to 
    port say D3 and see what happens, to find out if it was a DR900TM 
    hardware failure of the ASIC chip or some such thing. He did that and
    now for 3 weeks he hasn't seen the problem. 
    
    
    	Before I make the conclusion that my customer's problem is one
    where the DR900TM has developed a H/W failure, I thought I will ask
    others via this conference if anyone else has seen anything similar.
