WSS 2250 Icons Appear in InfoCenter on Client Installed Optivity NMS Systems To support new switching devices such as the Wireless Security Switch WSS 2250 and BayStack 5510 switch in Optivity NMS ONMS 10 1 you must install their respective Optivity Integration Toolkit OIT on the ONMS server OIT packages for all Nortel switching and routing products can be downloaded from the Nortel Networks Customer Support website at www nortelnetworks com After installing the OIT packages on your ONMS server it is possible that the icons for BayStack 5510 and WSS 2250 switches may not be populated in the InfoCenter Resources Switches folder on your MS Windows NT 2000 ONMS client The diagram below illustrates an example of what you might encounter amp Resources Switches OL x Objects 31 Change Count 31 Created January 26 2004 1 10 PML a 3 i 10 198778 22 101352002 B8PS2K EDS Botto BayStack 5510 10 135 204 14 10 135 177 2 nA 4704 53 72 a EIS TOP M ladle 190 135 174 5 10 135 204 215 Missing icons To enable the proper icons in InfoCenter you must copy or FTP the GIF files for these devices to the lt drive gt Optivity NMS images devices directory on your Windows NT 2000 client machine After the transfer is completed exit and restart InfoCenter on your client PC for the new icons to take effect see diagram below The GIF files for a given device are incorporated in its OIT package2. 2 KM buffer credits 100 KM 2KM 50 BB_C Some FC switches can enable a feature that optimizes switch buffering to ensure the highest possible performance on ISLs When this feature is installed on gateway switches the ISLs E_Ports are configured with up to 60 buffer credits The enhanced switch buffers help ensure that data transfer can occur at near full bandwidth to efficiently utilize the connection over extended links Distances vary depending on the manufacturer of the FC switch typically 50 to 100 km Some FC switches have a limited pool of buffers that are rationed amongst its ports to maximize buffer credits usage a more precise formula can be used to calculate a more accurate number of BB_C for a given E port Using the previous example of 100 KM the formula is as follows 2 distance in meters 4311 BB_C round up 2 100000 4311 46 39 or 47 BB_C Another consideration is the achievable throughput for a given distance and frame size For the same 100 KM distance with a 2 Kbyte frame size plus 8b 10b encoding add two bits per byte and the maximum BB_C configurable for that port the following formula can be use to determine what maximum bandwidth that can be achieved hence determining the type of connection BB_C frame size 8b 10b round trip delay 5 usec per KM max achievable BW 60 BB_C 20 000 0 0005 2 4 Gbp s If only a 1 Gbp s connection is available then adjustment BB_C would be req
