S3700 Service Port Stacking Support

Enterprise

Worldwide

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.
If the stack system works only in Layer 2 and Layer 3 forwarding scenarios, the number of stack member switches is recommended to be 2 to 5. If the stack system works in user access or gateway scenarios that require protocol interaction, the number of stack member switches is recommended to be 2 or 3. 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 3-6 Service port stacking support

Device Series	Port Supporting Stacking	Stack Cable	Rate of a Single Port	Remarks
S3700-EI	First two GE ports on the front panel	1.5 m SFP stack cable	2.5Gbit/s	All models support the stacking function except that a stack cannot be set up between the S3752EI and S3728EI. A switch supports a maximum of two logical stack ports, and each logical stack port contains one stack member port. A switch supports a maximum of two stack member ports.
S3700-SI	First two GE ports on the front panel	1.5 m SFP stack cable	2.5Gbit/s	All models support the stacking function except that a stack cannot be set up between the S3752SI and S3728SI. A switch supports a maximum of two logical stack ports, and each logical stack port contains one stack member port. A switch supports a maximum of two stack member ports.
