Is the sfp made by cisco? If not there are addition commands needed<br />
service unsupported-transceiver<br />
no errdisable detect cause gbic-invalid.

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Golang, also called Go, is an open source programming language that is a statically-typed language with syntax loosely derived from C, adding automatic memory management, type safety, some dynamic-typing capabilities, additional built-in types such as variable-length arrays and key-value maps, and a large standard library. Go is a general-purpose systems programming language that aims to be efficient both for development and execution with a focus on fast compilation and increased maintainability of large projects. Go was originally targeted at systems programming tasks such as building server/web applications, high throughput middleware and databases.
