![]() For details, see your appliance installation guide.Īnalyze Ethernet VLAN traffic from the following sources: Ethernet, Fast Ethernet, Gigabit Ethernet, trunk port, or Fast EtherChannel SPAN, RSPAN, or ERSPAN source port. The software continues to support baseline manageability features of SNMP such as MIB-2 and IF-TABLE for the NAM, and the health status and interface statistics that can be used by external products like Fault and Configuration Management offerings (for example, CiscoWorks LMS and Prime Infrastructure).Īpplies to NAM appliances only. Prime NAM uses web services as the northbound interface for data objects. Used as a southbound interface for configuration and data retrieval from switches and routers. Prime NAM integration with WAAS Central Manager provides for easier viewing of Prime NAM reports that are directly associated with Application Response Time measurements through the WAN, in both WAAS optimized and non-optimized environments. You can access Prime NAM from within the Central Manager interface. SPAN and NetFlow sources can be in effect simultaneously. For received NetFlow traffic, a default site will be created including all interfaces from that device. You must configure the NetFlow packet source to the NAM from a local switch or remote router using the device CLI. ![]() ![]() Prime NAM analyzes NetFlow from Managed Devices (Routers/Switches) You can monitor NetFlow records directly from remote switches or routers. ERSPAN supports source ports, source VLANs, and destination ports on different routers or switches, which provides remote monitoring of multiple routers or switches across your network. ERSPAN sends traffic to a network analyzer such as a SwitchProbe device or other Remote Monitoring (RMON) probe. You can monitor traffic on one or more ports, or one or more VLANs, and send the monitored traffic to one or more destination ports using ERSPAN. Use the RSPAN VLAN as the SPAN source for the NAM.Įncapsulated Remote Switched Port Analyzer (ERSPAN)1 You can monitor packet streams from remote switches, assuming that all traffic from a remote switch arrives at the local switch on a designated RSPAN VLAN. On some NAM platforms, using SPAN allows for NAM configuration without having to use the switch. Selecting an EtherChannel as a SPAN source is the same as selecting all physical ports comprising the EtherChannel as the SPAN source. You can direct a set of physical ports, a set of VLANs, or a set of EtherChannels to the NAM. Table A-1 Methods of Directing Traffic Method To understand which methods to use to direct specific traffic to the Prime NAM software, see Table A-1.
