What is Cisco Nexus FabricPath?
Introduced by Cisco in Nexus OS software Release 5.1(3), FabricPath allows architects to design highly scalable true Layer 2 fabrics. Similar to spanning tree, it provides an almost plug and play deployment model with the benefits of Layer 3 routing allowing FabricPath networks to scale at an unprecedented level.
What is vPC and vPC+?
vPC connects hosts and other devices to the network. vPC+ uses a pair of physical switches, like regular vPC does. vPC+ is different, as it creates a virtual switch. The rest of the fabricpath domain sees the host as connected to this virtual switch.
What are two benefits of Cisco FabricPath?
FabricPath offers following benefits:
- Simplified configuration.
- Maximizes bandwidth availability using ECMP.
- Provides design flexibility, redundancy and fault tolerance.
- No STP is required.
- FabricPath works by the principle of Conversational MAC learning.
- It offers ECMP and loop prevention by using TTL.
What is FabricPath networking?
FabricPath is Cisco’s proprietary, TRILL-based technology for encapsulating Ethernet frames across a routed network. Its goal is to combine the best aspects of a Layer 2 network with the best aspects of a Layer 3 network.
How do I verify packet drops on a Nexus 7000 switch?
Q. How do I verify packet drops on a Nexus 7000 Switch? A. Verify the Rx Pause and TailDrops fields from the output of the show interface {/} and show hardware internal errors module module # commands for the module with these ports.
What is enhanced vPC?
Enhanced vPC is a method that allows the connection of FEX in an active-active manner using vPC between the FEX and upstream Nexus switch, and at the same time connection of a device to the FEX host interfaces with a vPC.
Why do we need FabricPath?
Cisco FabricPath is about routing your data center traffic and helps doing load-sharing. It combines both Layer 2 and Layer 3 functions, thus giving simplicity of Layer 2 and also the intelligence of Layer 3. On the other hand, STP is only plug and play and does not have any Layer 3 intelligence.
