Security7-10Configuring SecurityFigure 7-4. Add MAC Address Windowd. Enter the desired MAC address in an xx:xx:xx:xx:xx:xx format, then clickon . A confirmation window will appear; if you click on Yes tosecure the address, it will appear in the Secure Addresses list box.4. To secure addresses for additional ports, click to select the desired port in theChannel X Port Security window; the Addresses window will automaticallydisplay the Learned and Secure addresses for the new port.Boards with Multiple CachesBecause of the number of ports they contain, some boards provide two separatefloating address caches: one for each bank of ports. In effect, this circumstanceallows you to configure as many as 64 additional secure addresses, as long as nomore than 32 are configured for each set of ports. For example, the TPR-36S,which has 26 ports, provides one 32-address cache for ports 1-13 and a secondcache for ports 14-26; the TPX-22S, which has 22 ports, provides one 32-addresscache for ports 1-10, and a second cache for ports 11-22.In any case, the Security application will keep track of how many caches arepresent and how many addresses have been assigned to each, and will disable theAdd button as appropriate.NOTEIf the maximum number of addresses has already been assigned to the floatingcache on the selected board, or if you have already secured two addresses on a non-LANVIEWSECURE MIM port, the Add button will be disabled.You can clear both Learned and Secure addresses (and re-start the learning process) byusing the Reset Learned Addresses option in the repeater-, module-, or port-level Securitywindow; see Resetting Learned Addresses, page 7-11.NOTENote thatLANVIEWSECURE TPXMIMs assigned wholly to Channel A contain no activecache, as the floating cache feature is not supported for MIMs operating on Channel A.Similarly, you will not be able to assign more than two secure addresses to any TPXMIMport while it is configured to operate on Channel A.
