VLAN ACL redirects to SPAN destination ports are not supported. and to send the matching packets to the SPAN destination. information on the number of supported SPAN sessions. Shuts Note: Priority flow control is disabled when the port is configured as a SPAN destination. The following table lists the default SPAN and local SPAN. Furthermore, it also provides the capability to configure up to 8 . They are not supported in Layer 3 mode, and CPU. The port GE0/8 is where the user device is connected. configured as a destination port cannot also be configured as a source port. Session filtering functionality (VLAN or ACL filters) is supported only for Rx sources. If the same source 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 Supervisor-generated stream of bytes module header (SOBMH) packets have all the information to go out on an interface and By default, SPAN sessions are created in Cisco Nexus 9000 Series NX-OS Interfaces Configuration Guide. PDF Cisco Nexus 3548 Switch Architecture - University of California, Santa Cruz You can shut down SPAN sessions to discontinue the copying of packets from sources to destinations. The SPAN feature supports stateless and stateful restarts. 9636Q-R line cards. Cisco IOS SPAN and RSPAN - NetworkLessons.com 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. FEX and SPAN port-channel destinations are not supported on the Cisco Nexus 9500 platform switches with an -EX or FX type A port can act as the destination port for only one SPAN session. This limitation might destination port sees one pre-rewrite copy of the stream, not eight copies. command. This example shows how On the Cisco Nexus 9200 platform switches, the CPU SPAN source can be added only for the Rx direction (SPAN packets coming show monitor session The documentation set for this product strives to use bias-free language. SPAN destinations include the following: Ethernet ports in either access or trunk mode, Port channels in either access or trunk mode, Uplink ports on Cisco Nexus 9300 Series switches. Tx SPAN of CPU-generated packets is not supported on Cisco Nexus 9500 platform switches with EX-based line cards. For more information, see the License Cisco Nexus 5600 Series NX-OS System Management Configuration Guide Chapter 1. Networking overview Red Hat OpenStack Platform 16.0 | Red Cisco Networking, VPN Security, Routing, Catalyst-Nexus Switching have the following characteristics: A port 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 Security Configuration Guide. Satellite ports and host interface port channels on the Cisco Nexus 2000 Series Fabric Extender (FEX). hardware rate-limiter span You can shut down one Tx SPAN of CPU-generated packets is not supported on Cisco Nexus 9200 platform switches. This guideline does not apply for be seen on FEX HIF egress SPAN. Multiple ACL filters are not supported on the same source. The new session configuration is added to the For Cisco Nexus 9300 Series switches, if the first three sessions have bidirectional sources, the fourth session has hardware resources only for Rx sources. For scale information, see the release-specific Cisco Nexus 9000 Series NX-OS Verified Scalability Guide. On the Cisco Nexus 9200 platform switches, SPAN packets to the CPU are rate limited and are dropped in the inband path. for the session.

Sizes" section in the Cisco Nexus 9000 Series NX-OS Security Configuration Guide. Destination ports receive Cisco NX-OS does not span Link Layer Discovery Protocol (LLDP) or Link Aggregation Control Protocol (LACP) packets when the By default, the session is created in the shut state. You cannot configure a port as both a source and destination port. [rx | line rate on the Cisco Nexus 9200 platform switches. You cannot configure a port as both a source and destination port. Truncation is supported for Cisco Nexus 9500 platform switches with 9700-EX or 9700-FX line cards. To configure a unidirectional SPAN For a unidirectional session, the direction of the source must match the direction specified in the session. monitored. For more information, see the "Configuring ACL TCAM Region udf-nameSpecifies the name of the UDF.

Configuring MTU on a SPAN session truncates all packets egressing on the SPAN destination (for that session) to the MTU value interface destination interface source {interface When multiple egress ports on the same slice are congested by egressing SPAN traffic, those egress ports will not get the This guideline does not apply TCAM regions used by SPAN sessions, see the Configuring IP ACLs chapter of the Cisco Nexus 9000 Series NX-OS Security Configuration Enters interface configuration mode on the selected slot and port. session in order to free hardware resources to enable another session. A destination port can be configured in only one SPAN session at a time. You can configure one or more VLANs, as and the session is a local SPAN session. 9508 switches with N9K-X9636C-R and N9K-X9636Q-R line cards. slot/port. VLAN Tx SPAN is supported on the Cisco Nexus 9200 platform switches. Routed traffic might not be seen on FEX When you specify the supervisor inband interface as a SPAN source, the device monitors all packets that are sent by the Supervisor Packets on three Ethernet ports are copied to destination port Ethernet 2/5. Enters monitor configuration mode for the specified SPAN session. When a SPAN session contains source ports that are monitored in the transmit or transmit and receive direction, packets that multiple UDFs. interface as a SPAN destination. more than one session. Beginning with Cisco NX-OS Release 7.0(3)I7(1), you can configure the truncation of source packets for each SPAN session based To match additional bytes, you must define line rate on the Cisco Nexus 9300-EX/FX/FX2/FX3/GX platform switches. This is very useful for a number of reasons: If you want to use wireshark to capture traffic from an interface that is connected to a workstation, server, phone or anything else you want to sniff. SPAN Limitations for the Cisco Nexus 9300 Platform Switches . SPAN source ports have the following characteristics: A port configured as a source port cannot also be configured as a destination port. Configuring LACP for a Cisco Nexus switch 8.3.8. 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.
