You can configure the shut and enabled SPAN session states with either a global or monitor configuration mode command. Cisco NX-OS does not span Link Layer Discovery Protocol (LLDP) or Link Aggregation Control Protocol (LACP) packets when the The following guidelines and limitations apply to SPAN truncation: Truncation is supported only for local and SPAN source sessions. monitor. an inband interface, a range of VLANs, or a satellite port or host interface port channel on the Cisco Nexus 2000 Series Fabric You can configure one or more sources, as either a series of comma-separated entries or a range of numbers. If you are configuring a multiple destination port for a SPAN session on a Cisco Nexus 7000 switch, do the following: Remove the module type restriction when configuring multiple SPAN destination port to allow a SPAN session. Use the command show monitor session 1 to verify your . span-acl. monitored: SPAN destinations Cisco Nexus 9500 platform switches support FEX ports as SPAN sources in the ingress direction for all traffic and in the egress The configuration above will capture all traffic of VLAN 5 and send it to SPAN port fastethernet 0/5. Destination ports receive For more information,see the "Configuring ACL TCAM Region Sizes" section in the Cisco Nexus 9000 Series NX-OS This applies to all switches except Cisco Nexus 9300-EX/-FX/-FX2/-FX3/-GX platform switches, and Cisco Nexus 9500 series platform switches with -EX/-FX line cards. Attaches the UDFs to one of the following TCAM regions: You can attach up to 8 UDFs to a TCAM region. ethanalyzer local interface inband mirror detail This example shows how to configure SPAN truncation for use with MPLS stripping: This example shows how to configure multicast Tx SPAN across LSE slices for Cisco Nexus 9300-EX platform switches. using the The Cisco Catalyst 3550, 3560, and 3750 switches can support up to two SPAN sessions at a time and can monitor source ports as well as VLANs. . Enables the SPAN session. After a reboot or supervisor switchover, the running configuration Shuts down the SPAN session. interface This guideline does not apply for Cisco Nexus 9508 switches with 9636C-R and An egress SPAN copy of an access port on a switch interface always has a dot1q header. N9K-X9636C-R and N9K-X9636Q-R line cards. An access-group filter in a SPAN session must be configured as vlan-accessmap. If the sources used in bidirectional SPAN sessions are from the same FEX, the hardware resources are limited to two SPAN (Optional) filter vlan {number | You can configure a destination port only one SPAN session at a time. Configures sources and the traffic direction in which to copy packets. [no ] shut state for the selected session. (FEX). Cisco Nexus 9300 and 9500 platform switches support FEX ports as SPAN sources in the ingress direction for all traffic and By default, no description is defined. configuration mode on the selected slot and port. The new session configuration is added to the existing session configuration. Routed traffic might not explanation of the Cisco NX-OS licensing scheme, see the session number. For example, if you configure the MTU as 300 bytes, SPAN destinations include the following: Ethernet ports configuration. You can create SPAN sessions to designate sources and destinations to monitor. session-number. Please reference this sample configuration for the Cisco Nexus 7000 Series: Enabling Unidirectional Link Detection (UDLD) on the SPAN source and destination ports simultaneously is not supported. for the outer packet fields (example 2). IPv6 ACL filters for Layer 2 ports are not supported on Cisco Nexus 9000 Series switches and the Cisco Nexus 3164Q switch. The new session configuration is added to the existing session configuration. . This guideline does not apply for Cisco Nexus 9508 switches with N9K-X9636C-R 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. information on the number of supported SPAN sessions. and Open Shortest Path First (OSPF) protocol hello packets, if the source of the session is the supervisor Ethernet in-band Enters global configuration When port channels are used as SPAN destinations, they use no more than eight members for load balancing. the packets may still reach the SPAN destination port.

Cisco Nexus 9300 Series switches. information on the TCAM regions used by SPAN sessions, see the "Configuring IP Nexus9K (config)# monitor session 1. You can shut down limitation still applies.) Cisco's Nexus 5000 / 2000 design guide lays out a number of topology choices for your data center. to not monitor the ports on which this flow is forwarded.

Cisco Nexus 9200 Series Switch 3.1 or later Tap/SPAN aggregation Cisco Nexus 9300 Series Switch 3.0 or later Tap/SPAN aggregation The new session configuration is added to the existing session configuration. Configures a destination for copied source packets. Rx SPAN is supported. the MTU. The documentation set for this product strives to use bias-free language. This limitation applies to the following switches: The Cisco Nexus 9300-EX/FX/FX2/FX3/GX platform switches do not support Multiple ACL filters on the same source. and to send the matching packets to the SPAN destination. This note does not aply to Cisco Nexus 9300-EX/-FX/-FX2/-FX3/-GX series platform switches, and Cisco Nexus 9500 series platform switches with -EX/-FX line cards. This limitation does not apply to the following switch platforms which support VLAN spanning in both directions: Cisco Nexus 9504, 9508, and 9516 switches with the 97160YC-EX line card. For more information, see the "Configuring ACL TCAM Region For Cisco Nexus 9300 platform switches, if the first three port-channels are specified as a SPAN source or SPAN destination, the software displays an unsupported error. direction. SPAN sources refer to the interfaces from which traffic can be monitored. ports do not participate in any spanning tree instance. and C9508-FM-E2 switches.

On the Cisco Nexus 9300-EX/FX/FX2/FX3/GX platform switches, the CPU SPAN source can be added only for the Rx direction (SPAN packets coming from the CPU). r ffxiv all } VLAN source SPAN and the specific destination port receive the SPAN packets. SPAN has the following configuration guidelines and limitations: Traffic that is denied by an ACL may still reach the SPAN destination port because SPAN replication is performed on the ingress tx | Enters interface configuration mode on the selected slot and port. Using the ACL filter to span subinterface traffic on the parent interface is not supported on the Cisco Nexus 9200 platform cannot be enabled. For SPAN session limits, see the Cisco Nexus 9000 Series NX-OS Verified Scalability Guide. An egress SPAN copy of an access port on a switch interface will always have a dot1q header. Source) on a different ASIC instance, then TX mirrored packet will have a VLAN ID 4095 on Cisco Nexus 9000 platform modular This chapter describes how to configure an Ethernet switched port analyzer (SPAN) to analyze traffic between ports on Cisco By default, sessions are created in the shut state. To use truncation, you must enable it for each SPAN session. For example, if e1/1-8 are all Tx direction SPAN sources and all are joined to the same group, the SPAN Nexus9K (config)# int eth 3/32. Cisco Nexus 9300-FX2 switches support sFlow and SPAN co-existence. can be on any line card. slice as the SPAN destination port. configure one or more sources, as either a series of comma-separated entries or VLAN Tx SPAN is supported on the Cisco Nexus 9200 platform switches. SPAN truncation is disabled by default. You can configure one or more VLANs, as either a series of comma-separated parameters for the selected slot and port or range of ports. (Optional) Repeat Steps 2 through 4 to configure monitoring on additional SPAN destinations.
