How to Commission the Cisco AS5850 Universal Gateway
Step 3 Do some useful memory calculations:
Total Processor = Total RAM – Cisco IOS software (use the show version command to get the MB
assigned for all of Cisco IOS software + processor)
cisco c5850 (R7K) processor (revision 0.12) with 491520K/32768K bytes of memory.
491520K = 480 MB
+ 32768K = 32 MB
Total = 512 MB (what you purchased)
Verify CPU Utilization
High utilization causes network performance problems. Knowing when the gateway is running at over
50% utilization is critical because the gateway might start dropping packets if an unexpected traffic burst
comes through, or if OSPF gets recalculated. Fast switching reduces CPU utilization.
To verify CPU utilization, perform the following steps.
Step 1 Verify CPU utilization.

CPU utilization for five seconds: 0%/0%; one minute: 0%; five minutes: 0%
