Precision Time Protocol with hardware Pulse-Per-Second port: The Cisco Nexus 3548 supports PTP operations with hardware assistance. Cisco Nexus 9300 platform switches support multiple ACL filters on the same source. When port channels are used as SPAN destinations, they use no more than eight members for load balancing. SPAN truncation is disabled by default. A port cannot be configured as a destination port if it is a source port of a span session or part of source VLAN. (Optional) filter vlan {number | (Optional) copy running-config startup-config. Saves the change persistently through reboots and restarts by copying the running configuration to the startup configuration. You can change the size of the ACL ternary content addressable memory (TCAM) regions in the hardware. Configures a destination You can configure only one destination port in a SPAN session. Security Configuration Guide. A single ACL can have ACEs with and without UDFs together. The following guidelines and limitations apply to egress (Tx) SPAN: SPAN copies for multicast packets are made prior to rewrite. You can specify the traffic direction to copy as ingress (rx), egress (tx), or both. ports have the following characteristics: A port mode. When traffic ingresses from an access port and egresses to a trunk port, an ingress SPAN copy of an access port on a switch By default, the session is created in the shut state. By default, sessions are created in the shut The bytes specified are retained starting from the header of the packets. CSCwd55175 Deleting a span port with QinQ vlan is breaking netflow.

Clears the configuration of the specified SPAN session. This guideline does not apply for Cisco Nexus 9508 switches with range} [rx ]}. 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 configured as a destination port cannot also be configured as a source port. This guideline does not apply for Cisco Nexus 9508 switches with 9636C-R and 9636Q-R line cards. All packets that Its also a two stage setup process, you have to define your monitoring ports first and then configure your monitoring sessions. The bytes specified are retained starting from the header of the packets. can alleviate this problem as well as traffic overload on the source forwarding instance by configuring a source rate limit for each SPAN session. Cisco Nexus 9000 version CPU SPAN destination port SPAN Ethanalyzer STEP1, SPAN Eth 1/53 . Furthermore, it also provides the capability to configure up to 8 . monitor To match additional bytes, you must define (Optional) It is not supported for SPAN destination sessions. Configures SPAN for multicast Tx traffic across different leaf spine engine (LSE) slices. 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. If SPAN is mirroring the traffic which ingresses on an interface in an ASIC instance and egresses on a layer 3 interface (SPAN An access-group filter in a SPAN session must be configured as vlan-accessmap. down the SPAN session.

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 NX-OS devices. Routed traffic might not be seen on FEX Therefore, the TTL, VLAN ID, any remarking due to egress policy, Cisco's Nexus 5000 / 2000 design guide lays out a number of topology choices for your data center. Destination You can configure a SPAN session on the local device only. You can configure only one destination port in a SPAN session. Enters the monitor configuration mode. The Cisco Nexus 3048, with its compact one-rack-unit (1RU) form factor and integrated Layer 2 and 3 switching, complements the existing Cisco Nexus family of switches. multiple UDFs. Packets with FCS errors are not mirrored in a SPAN session. Guide. direction only for known Layer 2 unicast traffic flows through the switch and FEX. You must first configure the 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. using the This section lists the guidelines and limitations for Cisco Nexus Dashboard Data Broker: . 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}} . UDLD frames are expected to be captured on the source port of such SPAN session, disable UDLD on the destination port of the The interfaces from which traffic can be monitored are called SPAN sources. Attaches the UDFs to one of the following TCAM regions: You can attach up to 8 UDFs to a TCAM region. 4 to 32, based on the number of line cards and the session configuration, 14. On Cisco Nexus 9300-EX/FX platform switches, SPAN and sFlow cannot both be enabled simultaneously. Switch(config)#show monitor Session 1 --------- Type : Local Session Source Ports : Both : Ge0/1 Destination Ports : Ge0/8 Encapsulation : Native . For port-channel sources, the Layer On the Cisco Nexus 9200 platform switches, SPAN packets to the CPU are rate limited and are dropped in the inband path. 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. direction. This limitation applies to the Cisco Nexus 97160YC-EX line card. Cisco Nexus 9300 and 9500 platform switches support FEX ports as SPAN sources in the ingress direction for all traffic and VLAN ACL redirects to SPAN destination ports are not supported. Suppose I had two Cisco switches each outputting some network traffic to a SPAN port, and I needed to send the sum of all that traffic to a third device for monitoring that traffic via libpcap. Shuts 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).
