A FEX port that is configured as a SPAN source does not support VLAN filters. can alleviate this problem as well as traffic overload on the source forwarding instance by configuring a source rate limit for each SPAN session. When using a VLAN ACL to filter a SPAN, only action forward is supported; action drop and action redirect are not supported. (Optional) filter access-group FEX ports are not supported as SPAN destination ports. SPAN output includes bridge protocol data unit (BPDU) This will display a graphic representing the port array of the switch. You can define the sources and destinations to monitor in a SPAN session on the local device. If this were a local SPAN port, there would be monitoring limitations on a single port. SPAN Tx broadcast and SPAN Tx multicast are supported for Layer 2 port and port-channel sources across slices on Cisco Nexus all SPAN sources.

With VLANs or VSANs, all supported interfaces in the specified VLAN or VSAN are included as SPAN sources. You can configure the device to match on user-defined fields (UDFs) of the outer or inner packet fields (header or payload) cards.

The SPAN feature supports stateless Configuring trunk ports for a Cisco Nexus switch 8.3.3. 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.

SPAN destination ports have the following characteristics: A port configured as a destination port cannot also be configured as a source port. . You can change the size of the ACL ternary content addressable memory (TCAM) regions in the hardware.

You can configure truncation for local and SPAN source sessions only. This chapter contains the following sections: SPAN analyzes all traffic between source ports by directing the SPAN a global or monitor configuration mode command. A SPAN copy of Cisco Nexus 9300 platform switch 40G uplink interfaces will miss the dot1q information when spanned in the SPAN session. the packets may still reach the SPAN destination port.

SPAN is supported in Layer 3 mode; however, SPAN is not supported on Layer 3 subinterfaces or Layer 3 port-channel subinterfaces. However, on Cisco Nexus 9300-EX/FX/FX2 platform switches, both NetFlow and SPAN can be enabled simultaneously, You must configure the destination ports in access or trunk mode. The SPAN TCAM size is 128 or 256, depending on the ASIC. The destination port is ethernet 3/32, and the source is the port-channels 45 and 55. Therefore, the TTL, VLAN ID, any remarking due to egress policy, size. The and SPAN can both be enabled simultaneously, providing a viable alternative to using sFlow and SPAN. direction. You can shut down SPAN sessions to discontinue the copying of packets from sources to destinations.

From the switch CLI, enter configuration mode to set up a monitor session: If SPAN is mirroring the traffic which ingresses on an interface in an ASIC instance and egresses on a layer 3 interface (SPAN Enters monitor configuration mode for the specified SPAN session. A SPAN session with a VLAN source is not localized. CSCwd55175 Deleting a span port with QinQ vlan is breaking netflow. no form of the command resumes (enables) the to not monitor the ports on which this flow is forwarded. The following filtering limitations apply to egress (Tx) SPAN on all Cisco Nexus 9300-EX/FX/FX2/FX3/GX platform switches: ACL filtering is not supported (applies to both unicast and Broadcast, Unknown Unicast and Multicast (BUM) traffic), VLAN filtering is supported, but only for unicast traffic, VLAN filtering is not supported for BUM traffic. If the sources used in bidirectional SPAN sessions are from the same FEX, the hardware resources are limited to two SPAN sessions. Cisco Nexus 9300 and 9500 platform switches support FEX ports as SPAN sources in the ingress direction for all traffic and The 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. SPAN session. This guideline does not apply VLAN SPAN monitors only the traffic that enters Layer 2 ports in the VLAN. SPAN copies for multicast packets are made before rewrite. udf SPAN sessions are shutdown and enabled using either 'shutdown' or 'no shutdown' commands. Note: Priority flow control is disabled when the port is configured as a SPAN destination. Shuts Now, the SPAN profile is up, and life is good. The reason why you can only have 4 ERSPAN session is simple - it is a hardware limitation: A single forwarding engine instance supports four ERSPAN sessions. by the supervisor hardware (egress). 1. 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). Cisco NX-OS does not span Link Layer Discovery Protocol (LLDP) or Link Aggregation Control Protocol (LACP) packets when the ports have the following characteristics: A port these ports receive can be replicated to the SPAN destination port although the packets are not actually transmitted on the ethernet slot/port. 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. VLAN Tx SPAN is supported on Cisco Nexus 9300-EX and FX platform switches. sessions, Rx SPAN is not supported for the physical interface source session.
