How to stack optical ports on a switch
For stacking, use only Cisco-certified StackWise cables (do not reuse 3750 or non-matching cables). Switch stacking is a feature of certain Cisco access layer switches which allows for the creation of a single logical device from many individual devices via a backside stack port connected by several stack cables. Stackable switches logically to become one switch. The major benefits of stacking. Approved stacking for av is a two-switch stack for redundant core When the switches are stacked all multicast traffic is flooded through the stack. PTP TC is not supported within a Stack. This ensures simplified management, enhanced redundancy, and greater flexibility in port distribution and bandwidth utilization.

How much does a 5-line optical module cost
The average 10G SFP price typically falls between $10 and $300, depending on the module type, transmission distance, and brand. For most standard enterprise and data center deployments, the practical buying range is much narrower—and far more predictable—than many price lists suggest. All price bands below are market-observed ranges (OEM-branded vs. Certification fees: Vendors pay switch-vendor license fees to test and certify modules for specific platforms. These fees, spread across total shipments, can add an implicit 5–8 % markup to each 400g transceiver. Click to get your 10G SFP+ transceiver modules from nearby warehouses.
