Individually, the ports may mean very little, but together there are business processes which may require adjustments. For example, 4 quad 1 Gig Ethernet ports may be used together, with the expectation that 2 can fail but enough bandwidth would still be supplied to meet the business need. The customer may wish to set a threshold for bandwidth at 1.8 GBit. Also, the throughput of the set may be compared consistently when equipment is rebooted nightly, weekly, or monthly, on a rolling schedule. Only the aggregate may truly be important from a performance management expectation.
