The Switch Port Management (SPM) features in NetMRI allow at-a-glance management of all switched access interfaces in the network. IT departments routinely under-estimate underestimate (and over-estimateoverestimate) port utilization and capacity requirements. In a large, switched spanning-tree network, some switches can go under-utilized while other switches in the network absorb unacceptably high loads. Switch port utilization trends are difficult to identify. Is switch port utilization static, increasing, or decreasing? Where are usage trends increasing? Decreasing? If certain switches support hosts that frequently leave their network segment (on business trips, for example) only to return within a week or two, how does the network manager control those temporarily vacated ports so that they remain available for their returning hosts?

Switch Port Management (and its polling functions) operates only with devices detected as Switches or Switch-Routers in NetMRI. For more information, see Performing On-Demand Switch Port Polling. |
Network device polling is the key mechanism for building Switch Port Management (SPM)'s switching information, and the polling features provide considerable flexibility. You use polling at the Device Group level to check for changes to any active device in that group. You can define polling time periods for individual device groups so that administrators have near-real-time capabilities for
