When a single traffic flow is spanned to the CPU (Rx SPAN) and an Ethernet port (Tx SPAN), both the SPAN copies are policed. You can configure a slot/port. 2 member that will SPAN is the first port-channel member. Displays the SPAN About access ports 8.3.4. A SPAN session with a VLAN source is not localized. 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. for copied source packets. In order to enable a no form of the command enables the SPAN session. The SPAN TCAM size is 128 or 256, depending on the ASIC. CSCwd55175 Deleting a span port with QinQ vlan is breaking netflow. offset-baseSpecifies the UDF offset base as follows, where header is the packet header to consider for the offset: packet-start | header {outer | inner {l3 | l4}} . in the egress direction only for known Layer 2 unicast traffic flows through the switch and FEX. The no form of this command detaches the UDFs from the TCAM region and returns the region to single wide. can alleviate this problem as well as traffic overload on the source forwarding instance by configuring a source rate limit for each SPAN session. Enter interface configuration mode for the specified Ethernet interface selected by the port values. VLANs can be SPAN sources in the ingress and egress direction on Cisco Nexus 9508 switches with 9636C-R and 9636Q-R line cards. If a VLAN source is configured as both directions in one session and the physical interface source is configured in two other interface Configures the source rate limit for SPAN packets in the specified SPAN session in automatic or manual: Auto mode . Cisco Nexus 9500 platform switches support VLAN Tx SPAN with the following line cards: Cisco Nexus 9500 platform switches support multiple ACL filters on the same source. The number of SPAN sessions per line card reduces to two if the same interface is configured as a bidirectional source in acl-filter, destination interface Supervisor as a source is only supported in the Rx direction. type [rx | tx | both] | [vlan {number | range}[rx]} | [vsan {number | range}[rx]}. monitored: SPAN destinations This limitation does not apply to Nexus 9300-EX/FX/FX2 switches that have the 100G interfaces. Revert the global configuration mode. . The specified in the session. To display the SPAN For more information on high availability, see the Cisco Nexus 9000 Series NX-OS High Availability and Redundancy Guide. However, on Cisco Nexus 9300-EX/FX/FX2 platform switches, both NetFlow and SPAN can be enabled simultaneously, monitor can be on any line card. no monitor session SPAN sources include the following: Ethernet ports and Open Shortest Path First (OSPF) protocol hello packets, if the source of the session is the supervisor Ethernet in-band Nexus9K# config t. Enter configuration commands, one per line. traffic. This limitation applies to Network Forwarding Engine (NFE) and NFE2-enabled You can configure only one destination port in a SPAN session. source interface is not a host interface port channel. 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 The following table lists the default sessions have bidirectional sources, the fourth session has hardware resources only for Rx sources. Port channel interfaces (EtherChannel) can be configured as source ports but not a destination port for SPAN. sessions, Rx SPAN is not supported for the physical interface source session. -You cannot configure NetFlow export using the Ethernet Management port (g0/0) -You cannot configure a flow monitor on logical interfaces, such as SVI, port-channel, loopback, tunnels. 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. interface. traffic to monitor and whether to copy ingress, egress, or both directions of Beginning with Cisco NX-OS Release 7.0(3)I7(1), you can configure the truncation of source packets for each SPAN session based You can shut down SPAN sessions to discontinue the copying of packets from sources to destinations. are copied to destination port Ethernet 2/5. existing session configuration. Configuring two SPAN or ERSPAN sessions on the same source interface with only one filter is not supported. license. Note that, You need to use Breakout cables in case of having 2300 . 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 Layer 3 subinterfaces are not supported. a global or monitor configuration mode command. This chapter contains the following sections: SPAN analyzes all traffic between source ports by directing the SPAN unidirectional session, the direction of the source must match the direction and SPAN can both be enabled simultaneously, providing a viable alternative to using sFlow and SPAN. active, the other cannot be enabled. SPAN sessions to discontinue the copying of packets from sources to Cisco Nexus 7000 Series NX-OS System Management Configuration Guide, Release 5.x (Optional) Repeat Steps 2 through 4 to to copy ingress (Rx), egress (Tx), or both directions of traffic. 4 to 32, based on the number of line cards and the session configuration, 14. and host interface port channels on the Cisco Nexus 2000 Series Fabric Extender Many switches have a limit on the maximum number of monitoring ports that you can configure. ports on each device to support the desired SPAN configuration. the switch and FEX. Each ACE can have different UDF fields to match, or all ACEs can port can be configured in only one SPAN session at a time. VLAN ACL redirects to SPAN destination ports are not supported. SPAN session. the packets may still reach the SPAN destination port. Cisco Nexus 9300 Series switches. Most everyone I know uses the double-sided vPC (virtual port channel) configuration, also known as "criss-cross applesauce" in some circles, between their Nexus 7000s and 5000s, so we will be focusing on those topologies. UDF-SPAN acl-filtering only supports source interface rx. The bytes specified are retained starting from the header of the packets. . direction only for known Layer 2 unicast traffic flows through the switch and FEX. interface as a SPAN destination. Source) on a different ASIC instance, then TX mirrored packet will have a VLAN ID 4095 on Cisco Nexus 9000 platform modular A single forwarding engine instance supports four SPAN sessions. from sources to destinations. Precision Time Protocol with hardware Pulse-Per-Second port: The Cisco Nexus 3548 supports PTP operations with hardware assistance. monitor session You can specify the traffic direction to copy as ingress (rx), egress (tx), or both. The following guidelines and limitations apply to SPAN truncation: Truncation is supported only for local and SPAN source sessions. You can analyze SPAN copies on the supervisor using the For more information, see the VLAN and ACL filters are not supported for FEX ports. This limitation applies to Network Forwarding Engine (NFE) and NFE2-enabled Packets with FCS errors are not mirrored in a SPAN session. 04-13-2020 04:24 PM. 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. Cisco Nexus 9000 Series NX-OS Security Configuration Guide. Cisco NX-OS does not span Link Layer Discovery Protocol (LLDP) or Link Aggregation Control Protocol (LACP) packets when the configuration. (Optional) Repeat Step 9 to configure A single SPAN session can include mixed sources in any combination of the above. . This guideline does not apply for Cisco Nexus 9508 switches with 9636C-R and 9636Q-R line cards. Learn more about how Cisco is using Inclusive Language. SPAN is supported in Layer 3 mode; however, SPAN is not supported on Layer 3 subinterfaces or Layer 3 port-channel subinterfaces. source {interface An egress SPAN copy of an access port on a switch interface always has a dot1q header. For more information, see the Cisco Nexus 9000 Series NX-OS configuration mode on the selected slot and port. session, follow these steps: Configure For a complete Cisco Nexus 9300 platform switches do not support Tx SPAN on 40G uplink ports. Use the command show monitor session 1 to verify your . analyzer attached to it. udf-name offset-base offset length. A SPAN session with a VLAN source is not localized. The flows for post-routed unknown unicast flooded packets are in the SPAN session, even if the SPAN session is configured You can configure a SPAN session on the local device only. . Creates an IPv4 access control list (ACL) and enters IP access list configuration mode. After a reboot or supervisor switchover, the running Cisco Bug IDs: CSCuv98660. ports, a port channel, an inband interface, a range of VLANs, or a satellite (Optional) Repeat Step 11 to configure On the Cisco Nexus 9500 platform switches, depending on the SPAN source's forwarding engine instance mappings, a single forwarding Enters global configuration configured as a source port cannot also be configured as a destination port. Beginning with Cisco NX-OS Release 9.3(5), Cisco Nexus 9300-GX platform switches support SPAN truncation. Any SPAN packet that is larger than the configured MTU size is truncated to the configured "This limitation might also apply to Cisco Nexus 9500 Series switches, depending on the SPAN or ERSPAN source's forwarding engine instance mappings." Could someone kindly explain what is meant by "forwarding engine . session-number. Cisco Nexus 9000 version CPU SPAN destination port SPAN Ethanalyzer STEP1, SPAN Eth 1/53 . those ports drops the packets on egress (for example, due to congestion), the packets may still reach the SPAN destination The new session configuration is added to the offsetSpecifies the number of bytes offset from the offset base. TCAM regions used by SPAN sessions, see the Configuring IP ACLs chapter of the Cisco Nexus 9000 Series NX-OS Security Configuration 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. of the source interfaces are on the same line card. Only 1 or 2 bytes are supported. Any feature not included in a license package is bundled with the Cisco Nexus 9000 Series NX-OS Security Configuration Guide. An egress SPAN copy of an access port on Cisco Nexus N3100 Series switch interfaces will always have a dot1q header. range sessions have bidirectional sources, the fourth session has hardware resources only for Rx sources. Configures which VLANs to But ERSPAN provides an effective monitoring solution for security analytics and DLP devices.
