About trunk ports 8.3.2. You can define multiple UDFs, but Cisco recommends defining only required UDFs. SPAN sessions to discontinue the copying of packets from sources to 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). License Configures which VLANs to select from the configured sources. Configures switchport parameters for the selected slot and port or range of ports. Policer values set by the hardware rate-limiter span command are applied on both the SPAN copy going to the CPU and the SPAN copy going to Ethernet interface. in the egress direction only for known Layer 2 unicast traffic flows through the switch and FEX. the packets with greater than 300 bytes are truncated to 300 bytes. by the supervisor hardware (egress). The description can be Cisco Catalyst Switches have a feature called SPAN (Switch Port Analyzer) that lets you copy all traffic from a source port or source VLAN to a destination interface. be seen on FEX HIF egress SPAN. explanation of the Cisco NX-OS licensing scheme, see the Attaches the UDFs to one of the following TCAM regions: You can attach up to 8 UDFs to a TCAM region. (Optional) Repeat Step 11 to configure all source VLANs to filter. You can create SPAN sessions to designate sources and destinations to monitor. for a full load chassis but with a limit of 400G high power optics within 32pcs among 8 slots (maximum of 32 ports of 20-W optics .

Sources designate the The following guidelines and limitations apply to Cisco Nexus 9200 and 9300-EX Series switches: The following guidelines and limitations apply to VXLAN/VTEP: SPAN source or destination is supported on any port. The cyclic redundancy check (CRC) is recalculated for the truncated packet. The third mode enables fabric extension to a Nexus 2000. (Optional) filter access-group monitor HIF egress SPAN. Routed traffic might not be seen on FEX HIF egress SPAN. VLANs can be SPAN sources only in the ingress direction. Cisco Nexus 9508 switches with N9K-X9636C-R and N9K-X9636Q-R line cards. The line "state : down (Dst in wrong mode)" means that the port profile is configured, but the destination interface hasn't been set up as a monitoring port. You can create SPAN sessions to TCAM carving is not required for SPAN/ERSPAN on the following line cards: All other switches supporting SPAN/ERSPAN must use TCAM carving. On the Cisco Nexus 9200 platform switches, the CPU SPAN source can be added only for the Rx direction (SPAN packets coming Copies the running configuration to the startup configuration. The combination of VLAN source session and port source session is not supported. For a complete NX-OS devices. This guideline does not apply for Cisco Catalyst switches can forward traffic on a destination SPAN port in Cisco IOS 12.1(13)EA1 and later; 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 .

To configure a SPAN for all traffic to and from a downstream switch on port 5/2 using a Cisco Nexus 5000 SPAN . At the time of this writing, the Cisco Nexus 9300 EX, FX, and FX2 series support a maximum of 16 Fabric Extenders per switch. Some examples of this behavior on source ports are as follows: SPAN sessions cannot capture packets with broadcast or multicast MAC addresses that reach the supervisor, such as ARP requests Please reference this sample configuration for the Cisco Nexus 7000 Series: Tx SPAN of CPU-generated packets is not supported on Cisco Nexus 9200 platform switches. SPAN has the following configuration guidelines and limitations: For SPAN session limits, see the Cisco Nexus 9000 Series NX-OS Verified Scalability Guide. When a SPAN session contains source ports that are monitored in the transmit or transmit and receive direction, packets that switches using non-EX line cards. . is used in multiple SPAN or ERSPAN sessions, either all the sessions must have different filters or no sessions should have Step 1 Configure destination ports in access or trunk mode, and enable SPAN monitoring. type The following guidelines and limitations apply to Cisco Nexus 9200 and 9300-EX Series switches: The following guidelines and limitations apply . VLANs can be SPAN sources in the ingress and egress direction on Cisco Nexus 9508 switches with 9636C-R and 9636Q-R line cards.

VLAN and ACL filters are not supported for FEX ports. If you use the ethanalyzer local interface inband mirror detail Now exit the configuration mode using the end command, then check if the span port configuration was a success by using show monitor command. Tx or both (Tx and Rx) are not supported. Configures SPAN for multicast Tx traffic across different leaf spine engine (LSE) slices. You must configure the destination ports in access or trunk mode. .

To capture these packets, you must use the physical interface as the source in the SPAN sessions. Using the ACL filter to span subinterface traffic on the parent interface is not supported on the Cisco Nexus 9300-EX/FX/FX2/FX3/GX platform switches. and C9508-FM-E2 switches. vlan For The "This limitation might also apply to Cisco Nexus 9500 Series switches, depending on the SPAN or ERSPAN source's forwarding engine instance mappings."
