How to check the hash conflict problem on MA5616 ?
Some of the mac-address form the clients could not learned by our DLSAM, even the packets already reached to DSLAM, A service interrupting can be caused by this problem.
1.Firstly we check the mac-address leaned by system, we can use the command "display mac-address all", If there are lots of mac-address(with the characteristic of sequence ) learned in a same vlan,
usually it could be confirmed the problem is caused by HASH conflict, but in our equipement there are no alarms or events outputing when HASH conflict happens, aslo it is impossible to query the hash conflict status,so we need some methods to confirm this.
2.The command "mac-address static service-port " is used to bind a static mac-address to a specified service-port, we can use this command to check if the hash conflict happens when we have related doubt, just try to add the mac-address (from the client, which can not learned by system) to the service-port,
1).if the command executes failed and get the prompt as "Failure: Configuring the hardware fails", it is very sure that the hash conflict happened.
2).If the mac-address bind successfully, that means it should be another problem, there are no hash conflict problem for this mac-address.
