أ. Virtual PortChannel (vPC) is a port-channeling concept that extends link aggregation to two separate physical switches.
Benefits of vPC include:
-
-
- Utilizes all available uplink bandwidth
- Allows the creation of resilient Layer 2 topologies based on link aggregation
- Eliminates the dependence of Spanning Tree Protocol in Layer 2 access distribution layer(س)
- Enables transparent server mobility and server high availability (ها) clusters
- Scales available Layer 2 bandwidth
- Simplifies network design
- Dual-homed servers can operate in active-active mode
- Faster convergence upon link failure
- Improves convergence time when a single device fails
- Reduces capex and opex
-
