The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter contains the following sections:
A Cisco Monitor Manager network consists of one or more Cisco Nexus 3000 and 3100 Series switches with Cisco Plug-in for OpenFlow dedicated for connecting multiple spanned ports and network taps from the production network infrastructure. Cisco Extensible Network Controller (XNC) programs the switches using the OpenFlow protocol. Cisco Monitor Manager filters the packets that travel the network and delivers them to a pool of connected monitoring devices.
Cisco Monitor Manager supports the following forwarding path options:
In Cisco Monitor Manager, you can use a filter to define the Layer 2 (L2), Layer 3 (L3), and Layer 4 (L4) criteria used to filter traffic. Traffic that matches the criteria in the filter is routed to the delivery ports and from there to the attached monitor devices.
You can use rules to associate filters to configured monitor devices. You can configure rules with or without a source. Rules with a source node and port use the Multipoint-to-Multipoint forwarding path option. Rules without a source port on a node use the loop-free Any-to-Multipoint forwarding path option.
When a rule is configured with the Deny option, the ingress edge ports may or may not be defined. Cisco Monitor Manager drops traffic on the specified ingress edge port(s) or on all nodes if no ingress edge ports are defined.
Each rule has a priority that can be configured. Rules with a higher priority are given precedence over those with a lower priority.
Rules can be created and saved without installing them. After they are saved, installation can be toggled on and off in the Cisco Monitor Manager GUI.
Note | The priority setting was moved from filters to rules in Cisco Extensible Network Controller (XNC) Release 1.5. If you upgraded from Cisco Extensible Network Controller (XNC) Release 1.0 to Cisco Extensible Network Controller (XNC) Release 1.5, any filters and rules that you previously configured in Cisco Monitor Manager 1.0 are automatically converted to the new format in Cisco Monitor Manager, Release 1.5. |
