Intrinsically safe network switch router or Layer 3 switches extra to get the required management special intrinsically safe network switch network switch can be selected from the scalability, manageability, two aspects to evaluate. When talking about scalability, many vendors cited the number of user ports to support their high reliability assurance, but this is not enough, you should also consider the following three points. Stacking the interconnection between devices on the ring-shaped scalability limitations degree. How many ports can switch from 1OMbps Ethernet upgrade to 100Mbps Ethernet ports. Switch uplink transmission to the rest of the network data stream restrictive. In addition, many Layer 3 stackable switch does not support service differentiation, service type or multi-protocol label switching, so these stackable switches require additional external router or Layer 3 switches to get the required management features. Many studies have shown that relates to the cost of running and managing the lifetime of the product than the product's cost of funds to be more original purchase cost. Therefore. Manageability became evaluate the overall value of the switch another key factor. Stackable managed switch inherent advantage over a single logical entity must manage multiple independent configuration and monitoring devices easier. However, we also have to consider it for the quality of service priority data streams (QoS), the ability to execute strategy and management. And one by one with the text replacement requires a lot of manpower, and there may be a mistake, so strategies must be published to the switch group, need a new strategy, the big boy of the switch should be able to be rapidly modified, therefore, need to check stackable switches support directory to support networks and Light Directory Access Protocol, and Common Open Policy Service (one kind of behavior is expected to implement a richer protocol). Users can use VLAN (Virtual Private Network) across multiple switches or stack equipment to manage the transport stream.
