Port Index Availability Chapter 1 Product Overview Send documentation comments to [email protected]. Port Index Availability The Cisco MDS 9500 Multilayer Directors are designed to operate with any combination of Cisco MDS 9000 modules. However, you should be aware of the maximum port availability your chassis can support. A port index is an internally assigned number that Cisco NX-OS uses to switch data packets within the director or fabric switch. When the maximum number of port indexes is reached in a chassis, any modules remaining or added to the chassis will not boot up. The number of physical ports on a Fibre Channel module is equal to its number of port indexes. However, for Gigabit Ethernet modules (IPS-8, IPS-4, MPS-14/2, MSM-18/4, and MSFM 18/4), one physical port is equal to four port indexes (one port index for iSCSI and three port indexes for FC IP tunnels). Table 1-8 lists the physical ports and port indexes (virtual ports) available per Cisco MDS 9000 module.

All Generation 1 modules reserve port indexes on fixed boundaries with Supervisor-1. See Table 1-9. 2. 18 Fibre Channel ports and four Gigabit Ethernet ports. 3. 18 Fibre Channel ports and four Gigabit Ethernet ports. 4. 14 Fibre Channel ports and two Gigabit Ethernet ports. Using any combination of modules that include a Generation 1 module or a Supervisor-1 module limits the port index availability to 252 on all Cisco MDS 9500 Series directors. Generation 1 modules also require contiguous port indexes where the system assigns a block of port index numbers contiguously starting from the first port index reserved for the slot that the module is inserted in (See Table 1-9).
