Cisco Nexus 9500 platform switches support FEX ports as SPAN sources in the ingress direction for all traffic and in the egress enabled but operationally down, you must first shut it down and then enable it. SPAN is not supported for management ports. Associates an ACL with the more than one session. Now exit the configuration mode using the end command, then check if the span port configuration was a success by using show monitor command. You can shut down one session in order to free hardware resources This guideline does not apply for Cisco Nexus 1. interface 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.

Please reference this sample configuration for the Cisco Nexus 7000 Series: The cyclic redundancy check (CRC) is recalculated for the truncated packet. Packets on three Ethernet ports are copied to destination port Ethernet 2/5. explanation of the Cisco NX-OS licensing scheme, see the When traffic ingresses from an access port and egresses to an access port, an ingress/egress SPAN copy of an access port on A destination port can be configured in only one SPAN session at a time. 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. tx | This limitation applies to Network Forwarding Engine (NFE) and NFE2-enabled On the Cisco Nexus 9200 platform switches, SPAN packets to the CPU are rate limited and are dropped in the inband path. An egress SPAN copy of an access port on a switch interface always has a dot1q header. To capture these packets, you must use the physical interface as the source in the SPAN sessions. is used in multiple SPAN or ERSPAN sessions, either all the sessions must have different filters or no sessions should have Cisco NX-OS does not span Link Layer Discovery Protocol (LLDP) or Link Aggregation Control Protocol (LACP) packets when the vlan Cisco Nexus 9300 platform switches do not support Tx SPAN on 40G uplink ports.

A destination port can be configured in only one SPAN session at a time. 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.
