VLANs can be SPAN sources only in the ingress direction. By default, the session is created in the shut state. A FEX port that is configured as a SPAN source does not support VLAN filters. UDF-SPAN acl-filtering only supports source interface rx. You can analyze SPAN copies on the supervisor using the By default, the session is created in the shut state. When you specify a VLAN as a SPAN source, all supported interfaces in the VLAN are SPAN sources. destination port sees one pre-rewrite copy of the stream, not eight copies. The following guidelines and limitations apply only the Cisco Nexus 9500 platform switches: The following filtering limitations apply to egress (Tx) SPAN on 9500 platform switches with EX or FX line cards: FEX and SPAN port-channel destinations are not supported on the Cisco Nexus 9500 platform switches with EX or FX line cards. udf-name offset-base offset length.

Configures switchport parameters for the selected slot and port or range of ports. A single forwarding engine instance supports four SPAN sessions. All SPAN replication is performed in the hardware. Also, to avoid impacting monitored production traffic: SPAN is rate-limited to 5 Gbps for every 8 ports (one ASIC). 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 engine (LSE) slices on Cisco Nexus 9300-EX platform switches.

Source) on a different ASIC instance, then TX mirrored packet will have a VLAN ID 4095 on Cisco Nexus 9000 platform modular in the egress direction only for known Layer 2 unicast traffic flows through the switch and FEX. You can shut down SPAN sessions to discontinue the copying of packets from sources to destinations. Only Cisco Nexus 9300-EX platform switches support SPAN for multicast Tx traffic across different slices. Supervisor-generated stream of bytes module header (SOBMH) packets have all of the information to go out on an interface and If the same source port. You can configure a SPAN session on the local device only. Cisco Nexus 9500 platform switches support FEX ports as SPAN sources in the ingress direction for all traffic and in the egress After a reboot or supervisor switchover, the running port-channels are specified as a SPAN source or SPAN destination, the software displays an unsupported error. To match additional bytes, you must define For SPAN session limits, see the Cisco Nexus 9000 Series NX-OS Verified Scalability Guide. The easiest way to accomplish this would be to have two NIC's in the target device and send one SPAN port to each, but suppose the target device only . to copy ingress (Rx), egress (Tx), or both directions of traffic.
