The investment in pure R & D ( the stuff the tax deductions are really supposed to be about ) has been long been missing from our world . Multilevel access security on the switch console and the Web management interface prevents unauthorized users from accessing or altering switch configurations and can be implemented using an internal user database on each switch or a centrally administered TACACS + or RADIUS server . As is always the case , early stage companies either grow or produce profit . These switch and host authentications are performed locally or remotely in each fabric . Cisco Fabric Manager can be used independently or in conjunction with third-party management applications . We are going to bet , this time , that industry leaders will recognize the importance of R & D and that the next wave will come from an already known player . For authentication of users with a Terminal Access Controller Access Control System ( TACACS + ) or RADIUS server , 802.1x provides port-level security . We expect to see some relatively interesting efforts on the parts of mid-level players to convert their market positions intop dominant ones by funding real R & D. Unicru tracks and correlates all the data in order to provide customers with best practice hiring statistics and performance improvement benchmark data . After this has been completed , a user simply has to enter the unique pieces of the configuration either through the CLI or through the Cisco Fabric Manager tool . The Top 10 Summary lists average and peak throughput values for host and storage connections , ISLs , and flows all in one compact report . Implementing switching platforms that accommodate growth in connectivity and functionality is one key requirement of a Data Center Switch . With this challenge of managing heterogeneous storage networking environment comes a host of new applications and services to fill the need . Threshold values may be set with user-specified levels or with baseline values automatically calculated from performance history . The services and support programs described in the table below are available as part of the Cisco Desktop Switching Service and Support solution , and are available directly from Cisco and through resellers . There are two sorts of R & D : Applied ( product improvements ) and pure ( experimentation in general areas in the hopes of discovering an innovation ) . In addition , for authentication of users with a TACACS + or a RADIUS server , 802.1x provides port-level security . If the statistics exceed either configured threshold , an event is shown on the Fabric Manager web client Events tab . The services and support programs described in Table 6 are available as part of the Cisco Desktop Switching Service and Support solution , and are available directly from Cisco and through resellers . Their readers ( users ) have become ( and / or are becoming ) proactive owners of their own destinies .
