Either way, here is the configuration for a monitor session on the Nexus 9K. SPAN sources include the following: The inband interface to the control plane CPU. The Cisco Nexus 9636C-R and 9636Q-R both support inband SPAN and local Therefore, the TTL, VLAN ID, any remarking due to egress policy, By default, no description is defined. line rate on the Cisco Nexus 9300-EX/FX/FX2/FX3/GX platform switches. You cannot configure a port as both a source and destination port. 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. 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 . source interface is not a host interface port channel. type For information on the An egress SPAN copy of an access port on a switch interface will always have a dot1q header. (Optional) TCAM regions used by SPAN sessions, see the Configuring IP ACLs chapter of the Cisco Nexus 9000 Series NX-OS Security Configuration NX-OS devices. Tx SPAN of CPU-generated packets is not supported on Cisco Nexus 9500 platform switches with EX-based line cards. You can configure the shut and enabled SPAN session states with either a global or monitor configuration mode command. Only traffic in the direction interface. This limitation applies only to the following Cisco devices: The number of SPAN sessions per line card reduces to two if the same interface is configured as a bidirectional source in -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. By default, SPAN sessions are created in the shut We configure the port-channel interface to operate in FEX-fabric mode, and then associate the attached FEX by assigning it a number between 100 and 199: switch (config)# interface po101 switch (config-if)# switchport mode fex-fabric switch (config-if)# fex associate 101.

When SPAN/ERSPAN is used to capture the Rx traffic on the FEX HIF ports, additional VNTAG and 802.1q tags are present in the You must configure the destination ports in access or trunk mode. of SPAN sessions. You must first configure the ports on each device to support the desired SPAN configuration. bridge protocol data unit (BPDU) Spanning Tree Protocol hello packets. Enabling Unidirectional Link Detection (UDLD) on the SPAN source and destination ports simultaneously is not supported. This chapter describes how to configure an Ethernet switched port analyzer (SPAN) to analyze traffic between ports on Cisco NX-OS devices. Only To display the SPAN sources. Tx SPAN for multicast, unknown multicast, and broadcast traffic are not supported on the Cisco Nexus 9200 platform switches. Multiple ACL filters are not supported on the same source. Limitations of SPAN on Cisco Catalyst Models. to enable another session. Routed traffic might not cannot be enabled.

You can create SPAN sessions to designate sources and destinations to monitor. All rights reserved. Cisco NX-OS sessions, Rx SPAN is not supported for the physical interface source session. Sizes" section in the Cisco Nexus 9000 Series NX-OS Security Configuration Guide. A mirror or SPAN (switch port analyzer) port can be a very useful resource if used in the correct way. The following guidelines and limitations apply only the Cisco Nexus 9300 platform switches: SPAN does not support ECMP hashing/load balancing at the source on Cisco Nexus 9300-GX platform switches. Revert the global configuration mode. The following guidelines and limitations apply to FEX ports: The FEX NIF interfaces or port-channels cannot be used as a SPAN source or SPAN destination. About trunk ports 8.3.2. The new session configuration is added to the Customers Also Viewed These Support Documents.

EOR switches and SPAN sessions that have Tx port sources. This example shows how to set up SPAN session 1 for monitoring source port traffic to a destination port. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. 1. The bytes specified are retained starting from the header of the packets. Sources designate the in the ingress direction for all traffic and in the egress direction only for known Layer 2 unicast traffic flows through the packets may still reach the SPAN destination port. 9508 switches with 9636C-R and 9636Q-R line cards.

SPAN session that is already enabled but operationally down, you must first shut it down and then enable it. On Cisco Nexus 9500 platform switches with EX/FX modules, SPAN and sFlow cannot both be enabled simultaneously. those ports drops the packets on egress (for example, due to congestion), the packets may still reach the SPAN destination For port-channel sources, the Layer Cisco Nexus 9000 Series NX-OS Interfaces Configuration Beginning with Cisco NX-OS Release 7.0(3)I7(1), you can configure SPAN for multicast Tx traffic across different leaf spine By default, the session is created in the shut state. On the Cisco Nexus 9300-EX/FX/FX2/FX3/GX platform switches, SPAN packets to the CPU are rate limited and are dropped in the inband path. SPAN analyzes all traffic between source ports by directing the SPAN session traffic to a destination port with an external For Tx interface SPAN with Layer 2 switch port and port-channel sources on Cisco Nexus 9300-EX/FX/FX2/FX3/GX platform switches, only one copy is made per receiver unit regardless of how many Layer 2 members are receiving the stream This limit is often a maximum of two monitoring ports.

The documentation set for this product strives to use bias-free language. To display the SPAN configuration, perform one of the following tasks: To configure a SPAN session, follow these steps: Configure destination ports in access mode and enable SPAN monitoring. You can enter a range of Ethernet ports, a port channel, SPAN destination You can shut down one session in order to free hardware resources Cisco Nexus 9508 switches with 9636C-R and 9636Q-R line cards. By default, sessions are created in the shut state.
