Virtual Chassis Stacking

Max physical switches per stack, at the edge8Max physical switches per stack, at the core2Stack ports (pre-configuration)No pre-configured stacking port: any 100G, 25G, or 10G port and any media type can be used for stackingStack ports (max number)1G models: up to 4 (10G) ports per switch 10G models and up: up to 16 ports (10G, 25G, 100G) per switchStack ports (max speed limitation)Stacking link only works on the highest speed supported by a Stack port. A 25G port, when configured in Stack mode, only operates at 25G - it cannot operate at 10G. Similarly, a 100G port, when configured in Stack mode, only operates at 100G.Stacking limitation (mutually exclusive features)Stacking, AVB, and PTP TC are mutually exclusive features: M4350 stack cannot run AVB, nor PTP TC (or BC/GM)Vertical and horizontal stacking topologiesChain, single ring, dual ring, mesh, double starDistant stacking using fiberYesNon-stop forwarding (NSF)YesHitless management unit failover and failbackYes, no service interruption across the stackAutomatic unit replacement (AUR)YesDistributed Link Aggregation (LAGs across the stack)YesStack with M4300 switchesNot supported, only M4350 models
