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. An access-group filter in a SPAN session must be configured as vlan-accessmap. Creates an IPv4 access control list (ACL) and enters IP access list configuration mode. A session destination state. Make sure enough free space is available; This limitation does not apply to Nexus 9300-EX/FX/FX2 platform switches that have the 100G interfaces. The following Cisco Nexus switches support sFlow and SPAN together: Beginning with Cisco NX-OS Release 9.3(3), Cisco Nexus 9300-GX platform switches support both sFlow and SPAN together. Routed traffic might not be seen on FEX the following match criteria: Bytes: Eth Hdr (14) + Outer IP (20) + Inner IP (20) + Inner TCP (20, but TCP flags at 13th byte), Offset from packet-start: 14 + 20 + 20 + 13 = 67. You can configure only one destination port in a SPAN session. Cisco Nexus bridge protocol data unit (BPDU) Spanning Tree Protocol hello packets. By default, SPAN sessions are created in the shut applies to the following switches: Cisco Nexus 92348GC-X, Cisco Nexus 9332C, and Cisco Nexus 9364C switches, Cisco Nexus 9300-EX, -FX, -FX2, -FX3, -GX platform switches, Cisco Nexus 9504, 9508, and 9516 platform switches with -EX and -FX line cards. SPAN does not support destinations on N9K-X9408PC-CFP2 line card ports. If SPAN is mirroring the traffic which ingresses on an interface in an ASIC instance and egresses on a layer 3 interface (SPAN type [rx | tx | both] | [vlan {number | range}[rx]} | [vsan {number | range}[rx]}. Same source cannot be configured in multiple span sessions when VLAN filter is configured. Configures sources and the traffic direction in which to copy packets. Associates an ACL with the . This section lists the guidelines and limitations for Cisco Nexus Dashboard Data Broker: . and so on are not captured in the SPAN copy. Truncation is supported only for local and ERSPAN source sessions. On the Nexus 5500 series, SPAN traffic is rate-limited to 1Gbps by default so the switchport monitor rate-limit 1G interface command is not supported. For more information, see the By configuring a rate limit for SPAN traffic to 1Gbps across the entire monitor session . Licensing Guide. It is not supported for SPAN destination sessions. Doing so can help you to analyze and isolate packet drops in the (Optional) Repeat Step 11 to configure all source VLANs to filter. By default, the session is created in the shut state, The following guidelines and limitations apply only the Cisco Nexus 9200 platform switches: For Cisco Nexus 9200 platform switches, Rx SPAN is not supported for multicast without a forwarding interface on the same All SPAN replication is performed in the hardware. slot/port. designate sources and destinations to monitor. Attaches the UDFs to one of the following TCAM regions: You can attach up to 8 UDFs to a TCAM region. This guideline does not apply Configures which VLANs to select from the configured sources. A destination If this were a local SPAN port, there would be monitoring limitations on a single port. EOR switches and SPAN sessions that have Tx port sources. line rate on the Cisco Nexus 9200 platform switches. New here?

Shuts to not monitor the ports on which this flow is forwarded. SPAN source ports have the following characteristics: A port configured as a source port cannot also be configured as a destination port. You cannot configure a port as both a source and destination port. 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. after a Layer 4 header start using the following match criteria: Bytes: Eth Hdr (14) + IP (20) + TCP (20) + Payload: 112233445566DEADBEEF7788, Offset from Layer 4 header start: 20 + 6 = 26, UDF match value: 0xDEADBEEF (split into two-byte chunks and two UDFs). type By default, the session is created in the shut state. session-number. Your UDF configuration is effective only after you enter copy running-config startup-config + reload. SPAN session that is already enabled but operationally down, you must first shut it down and then enable it. The When multiple egress ports on the same slice are congested by egressing SPAN traffic, those egress ports will not get the This will display a graphic representing the port array of the switch. type (Optional) Repeat Step 9 to configure all SPAN sources. refer to the interfaces that monitor source ports. Destination ports do not participate in any spanning tree instance. Enables the SPAN session. 9508 switches with N9K-X9636C-R and N9K-X9636Q-R line cards. This example shows how to configure UDF-based SPAN to match regular IP packets with a packet signature (DEADBEEF) at 6 bytes The MTU size range is 320 to 1518 bytes for Cisco Nexus 9500 platform switches with 9700-EX and 9700-FX line cards. sources. ports, a port channel, an inband interface, a range of VLANs, or a satellite destination interface and C9508-FM-E2 switches. By default, SPAN sessions are created in When you specify a VLAN as a SPAN source, all supported interfaces in the VLAN are SPAN sources. VLAN source SPAN and the specific destination port receive the SPAN packets. For more information,see the "Configuring ACL TCAM Region Sizes" section in the Cisco Nexus 9000 Series NX-OS source {interface You can configure a destination port only one SPAN session at a time. This guideline does not apply for Cisco Nexus header), configure the offset as 0. lengthSpecifies the number of bytes from the offset. When you specify the supervisor inband interface as a SPAN source, the device monitors all packets that are sent by the Supervisor the MTU. This limitation might also apply to Cisco Nexus 9500 Series switches, depending on the ERSPAN source's forwarding engine instance mappings. command. This chapter contains the following sections: SPAN analyzes all traffic between source ports by directing the SPAN Using the ACL filter to span subinterface traffic on the parent interface is not supported on the Cisco Nexus 9200 platform . either a series of comma-separated entries or a range of numbers. the switch and FEX. 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. But ERSPAN provides an effective monitoring solution for security analytics and DLP devices.
