Port mirroring 3 • If you have NPIV or 10-bit address mode enabled on a Brocade 300, 5300, 5410, 5450, 5460, 5470, 5480, 7800, and the M5424 platforms, all devices from the same NPIV port or 10-bit addressing mode hit the same mirror connection, regardless of different AL_PAs, since the validation is done only for the first 16-bits of the SID/DID. • Port mirroring is not supported for the shared area ports of 48-port blades in the default switch. However, when the ports are assigned to a 10-bit address logical switch, port mirroring is supported. On the Brocade FR4-18i blade, if you define multiple mirror connections for the same F_PORT (SID or DID), all the connections must share the same mirror port. Supported platforms Port mirroring is supported only in FC ports. In general, a platform or blade supporting port mirroring supports both the mirror ports and the mirror connections. Exemptions are listed in Table 8.
