Multichassis EtherChannel (MEC) allows for the aggregation of links across multiple switches, providing increased redundancy and bandwidth. This is typically used in environments with stacked or virtualized switches (e.g., Cisco VSS or Cisco StackWise).
Use Cases for Multichassis EtherChannel:
- Redundancy: Links can terminate on different physical switches, providing redundancy in case one switch fails.
- Increased Bandwidth: Aggregates bandwidth across multiple switches.
- Simplified Management: Treated as a single logical link, simplifying network management and configuration.
- High Availability: Critical for environments requiring high availability and uptime.
