2. In a subsequent step you must tag the associated switch fabric module backplane port as well 4 On each Layer 3 switching module with VLANs that you want to perform routing define a routing interface for each protocol based or network based VLAN Verify that the routing interface is defined to use the same network or subnetwork as any other module that supports the VLAN Use the EME to connect to the switch fabric module and configure all VLANs that will pass traffic through the Layer 2 switch fabric module that is VLANs that are associated with switching modules or the GEN interface modules a For each VLAN definition that is associated with one or more switching modules include the switch fabric module backplane ports that correspond to the VLAN s participating switching modules For example if the VLAN s participating modules reside in slots 3 and 5 include switch fabric module ports 5 and 9 in the VLAN definition on the switch fabric module Tag these switch fabric module ports if the backplane ports of the corresponding switching modules are tagged For each VLAN verify that the tagging type for a switch fabric module port matches its associated backplane switching module port For each VLAN definition for 2 port GEN interface modules include the switch fabric module backplane ports that correspond to the VLAN s GEN interface modules For example if the VLAN s GEN interface module resides in slot 6 you define swi
