Fex With vPC and ISSU

Fex With vPC and ISSU

FEX design support with Nexus 70000 and vPC:

Fex is the Fabric Extender and its connection with Nexus 7000 is very limited and on very less line cards.

FEX can be connected to the following parent line cards:

• 32 X 10-Gbps ETH ports line card (N7K-M132XP-12 and N7K-M132XP-12L)
• 24 X 10-Gbps ETH ports line card (N7K-M224XP-23L)
• 48 X 1/10-Gbps ETH ports line card (N7K-F248XP-25, N7K-F248XP-25E, N77-F248XP-23E, N7K-F348XP-25, N77-F348XP-23)
• 6 X 40-Gbps ETH ports line card (N7K-M2406FQ-23L) in native 40G mode and break-out mode
• 12 X 40-Gbps ETH ports line card (N7K-F312FQ-25) in native 40G mode and break-out mode
• 24 X 40-Gbps ETH ports line card (N77-F324FQ-25) in native 40G mode and break-out mode

Models of FEX supported as of NX-OS 6.0 are:

• N2K-C2232PP (32 X 1/10-Gbps fiber Host Interface and 8 X 10-Gbps FEX uplinks)
• N2K-C2248TP-E / N2K-C2248TP-1GE (48 X 100-Mbps/1-Gbps copper Host Interface and 4 X 10-Gbps FEX uplinks)
• N2K-C2224TP / N2K-C2224TP-E (24 X 100-Mbps/1-Gbps copper Host Interface and 4 X 10-Gbps FEX uplinks)
• N2K-C2232TM / N2K-C2232TM-E (32 X 1/10-Gbps copper Host Interface and 8 X 10-Gbps FEX uplinks)
• N2K-C2248PQ (48 X 1/10G Fiber Host Interface and 4 X 40-Gbps FEX uplinks)
• N2K-C2348UPQ (48 X 1/10G Fiber Host Interface and 6 X 40-Gbps FEX uplinks)
• N2K-C2348TQ (48 X 100-Mbps/1/10-Gbps copper Host Interface and 6 X 40-Gbps FEX uplinks)

Following is the sample topology which can be used as reference to connect FEX with Nexus 7000.

All models of FEX (2224, 2248 and 2232) support 8 port-channel member ports max. Total number of member ports in a host vPC configuration can go up to 16. In a host vPC configuration, there is no requirement that both FEX models match on both sides of the vPC. FEX 2224 can be used in the left side and FEX 2248 can be used on the right side for instance.
