Performance management maintains interwork performance at acceptable levels by measuring and managing various work performance variables. ? SPAN selects and copies work traffic to send to a work analyzer. ? Remote SPAN is a variation of SPAN that sends monitored traffic through an intermediate switch rather than directly to the traffic analyzer. ? A NAM uses SNMP RMON information to monitor and analyze work traffic. ? Use the show mands to verify NAM configuration. 169。 2022, Cisco Systems, Inc. All rights reserved.
