Connecting Leaf Switches To Spine Switches - Cisco Nexus 93600CD-GX Hardware Installation Manual

Connecting Leaf Switches to Spine Switches

• For a VIC 1455 SFP28 module, 10-Gigabit only, use one of the following sets of transceivers and cables:
• Cisco 10GBASE-LR transceivers (SFP-10G-LR) supporting a link length of up to 6.1 miles (10 km)
• Cisco 10GBASE-SR transceivers (SFP-10G-SR) supporting the following link lengths:
• Using 2000 MHz MMF (OM3) for up to 984 feet (300 m)
• Using 4700 MHz MMF (OM4) for up to 1312 feet (400 m)
• Cisco SFP+ Active Optical Cables (SFP-10G-AOCxM [where x=1, 2, 3, 5, 7, or 10 for lengths in meters])
• Cisco SFP+ Twinax Cables (SFP-H10GB-CUxM [where x=1, 2, 3, 5, 7, or 10 for lengths in meters])
Note The VIC 1455 has 4 ports, port-1, port-2, port-3, and port-4 from left to right.
• All ports must have the same speed, either 10-Gigabit or 25-Gigabit.
• Port-1 and port-2 is one pair, corresponding to eth2-1 on APIC and port-3 and port-4 is another pair,
corresponding to eth2-2 on APIC. Only one connection is allowed for each pair. For example, you can connect
one cable to either port-1 or port-2, and connect another cable to either port-3 or port-4 (please do not connect
two cables on any pair).

Step 2 Connect the other end of the interface cable to a downlink port on a leaf switch.
• For a Cisco 10GBASE-LR or -SR transceiver and cable, insert the transceiver into a downlink optical port on a leaf
switch before connecting the cable to the transceiver.
• For Cisco SFP+ Active Optical Cables, insert the transceiver on the cable into a downlink optical port on a leaf
switch.
• For a 10GBASE-T copper cable, insert the RJ-45 connector on the cable into a downlink BASE-T port on a leaf
switch.

Connecting Leaf Switches to Spine Switches

For optimal forwarding between endpoints, you must connect each leaf switch to every spine switch in the
same ACI fabric.
