S5720-EI Service Port Stacking Support
- For the cables that can be used as stack cables, see "Cables" in the Hardware Description. Using other cables may cause exceptions in the stack system, for example, frequent error-down events on stack ports.
- Combo ports cannot function as stack member ports.
- For stacking-supported service ports, some of them can be used as stack ports, whereas some can be used as ordinary service ports.
- In V200R009C00 and later versions, if MPLS-incapable S5720-EIs exist in a stack, this stack cannot have MPLS enabled. If member devices in a stack are running MPLS services, adding MPLS-incapable S5720-EIs to the stack is not allowed. To check whether S5720-EIs support MPLS, run the display device capability command.
- The number of stacked switches is recommended to be 2 to 9. In addition, when using iMaster NCE-Campus to manage and maintain a stack, ensure that the stack has no more than four member switches.
