S5730-SI 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.
Stack card stacking and service port stacking (including ordinary cable stacking and dedicated stack cable stacking) cannot be used together. If service port configurations are correct, service port stacking is preferred over stack card stacking. If stack card stacking has been used to set up a stack, to use service port stacking to set up the stack, you need to restart the stack to make service port stacking takes effect after configuring service port stacking.
40GE ports on interface card cannot be used together with 40GE ports on the ES5D21VST000 stack card to set up a stack.
S5730-SI series switches of all versions can set up stacks in service port stacking mode using dedicated stack cables.
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.

Table 3-21 Service port stacking support

Device Series	Port Supporting Stacking	Stack Cable	Rate of a Single Port	Remarks
S5730-SI	10GE optical ports on the front panel	1 m, 3 m, and 5 m SFP+ passive high-speed copper cables 10 m SFP+ active high-speed copper cables 3 m and 10 m AOC cables 10GE SFP+ optical module and optical fiber 0.5 m and 1.5 m SFP+ dedicated stack cable	10Gbit/s	Any models of the S5730-SI series can set up a stack. When 40GE optical ports are used as stack ports, a switch supports a maximum of two logical stack ports, and each logical stack port supports at least one stack member port and at most four stack member ports. A switch supports a maximum of four stack member ports. When 10GE ports are used as stack ports, a switch supports a maximum of two logical stack ports, and each logical stack port supports at least one stack member port and at most eight stack member ports. A switch supports a maximum of eight stack member ports. Two rates of ports on an S5730-SI can both be configured as stack member ports, but each logical stack port contains only the same type of stack member ports. 40GE ports do not support the stacking function after they are split into 10GE ports. If stack member ports on the front panel are connected using 1 m, 3 m, or 5 m QSFP+ passive high-speed copper cables, their working speed can be increased to 48 Gbit/s using the stack port speed command. After their working speed is increased to 48 Gbit/s, switches using these ports cannot set up a stack with switches using ports with the working speed 40 Gbit/s.
