Table 71 shows what LSAN information is stored in each FC router before and after LSAN zone binding is in effect.

How LSAN zone binding works LSAN zone binding uses an FC router matrix, which specifies pairs of FC routers in the backbone fabric that can access each other, and an LSAN fabric matrix, which specifies pairs of edge fabrics that can access each other. Set up LSAN zone binding using the fcrLsanMatrix command. This command has two options: -fcr and -lsan. The -fcr option is for creating and updating the FC router matrix, and the -lsan option is used for Fabric OS 6.1.x administrator guide 333
