2-port-SFP+ 4-port-Hybrid 4-port-SFP+ DGS-3130 Layer 3 Stackable Managed Switch CLI Reference Guide Specifies 2 SFP+ switch ports to be used for stacking. Specifies 2 10GBase-T and 2 SFP+ switch ports to be used for stacking. Specifies 4 SFP+ switch ports to be used for stacking. Default By default, 2-port-SFP+ is used. Command Mode Privileged EXEC Mode. Command Default Level Level: 12. Usage Guideline Use this command to change the stacking port bandwidth. The stacking bandwidth must be configured before the Switch is stacked with other switches. Physical stacking needs to be enabled and can be configured to support either a 2-port or a 4-port stacking configuration. When the 2-port-10GBaseT stacking configuration is used, a full-duplex speed of up to 40Gbps will be used between two switches.  The DGS-3130-30TS/30S/30PS will use physical ports 25 and 26 for 2-port stacking.  The DGS-3130-54TS/54S/54PS will use physical ports 49 and 50 for 2-port stacking. When the 2-port-SFP+ stacking configuration is used, a full-duplex speed of up to 40Gbps will be used between two switches.  The DGS-3130-30TS/30S/30PS will use physical ports 29 and 30 for 2-port stacking.  The DGS-3130-54TS/54S/54PS will use physical ports 53 and 54 for 2-port stacking. When the 4-port-Hybrid stacking configuration is used, a full-duplex speed of up to 80Gbps will be used between two switches using four physical ports aggregated into two virtual stacking ports.  The DGS-3130-30TS/30S/30PS will use physical ports 25, 26, 29, and 30 for 4-port stacking.  The DGS-3130-54TS/54S/54PS will use physical ports 49, 50, 53, and 54 for 4-port stacking. When the 4-port-SFP+ stacking configuration is used, a full-duplex speed of up to 80Gbps will be used between two switches using four physical ports aggregated into two virtual stacking ports.  The DGS-3130-30TS/30S/30PS will use physical ports 27, 28, 29, and 30 for 4-port stacking.  The DGS-3130-54TS/54S/54PS will use physical ports 51, 52, 53, and 54 for 4-port stacking.
