Access Gateway mapping

Port mapping
F_Ports must be mapped to N_Ports before the F_Ports can come online. Figure 5 on page 16
shows an example in which eight F_Ports are mapped evenly to four N_Ports on a switch in AG
mode. The N_Ports connect to the same fabric through different Edge switches.
FIGURE 5 Port mapping example
Table 6 provides a description of the port mapping in Figure 5.
Default port mapping
When you first enable a switch for AG mode, the F_Ports are mapped to a set of predefined N_Ports
by default. Table 7 on page 17 describes the default port mapping for all supported hardware
platforms. By default, Failover and Failback policies are enabled on all N_Ports.
If you want to change the default mapping, refer to “Adding F_Ports to an N_Port” on page 20. Note
that all F_Ports must be mapped to an N_Port before the F_Port can come online.
