Multi-Chassis Trunking

• Multi-Chassis Trunking (MCT)

• Enhancement to Link Aggregation Groups

• Provides nodal in addition to link and modular

redundancy

• Operates at the physical level to provide sub-

second failover

• MCT Peers

• Pair of physical switches act as one logical

switch

• Access switch/server connected via LAG

• LAGs are spread across the MCT pair

• MCT Pair a single logical switch

• No loop in the logical topology

• All links are now Active/Active links

• Sub-second for link/module or node failure
