HUAWEI-USERLOG-MIB
The HUAWEI-USERLOG-MIB contains objects to manage configuration and monitor running state for userlog feature. For users who access network through NAT and BAS equipments, their IP addresses are generally unfixed, and so it is hard to exactly locate which host a certain access comes from and which user initiates it. This decreases the network security. User log is designed to solve the problem. User log can record Network Address Translation (NAT) flow information, and login/ logout information and flow information of Broadband Access Server (BAS) user, thus enabling the administrator know address information before NAT, access record of BAS user, etc. Then, network activities and operations can be queried and tracked, and network availability and security are improved accordingly.
