Configuring SPAN On Cisco Catalyst Switches - Monitor & Capture Network This limitation applies to the following switches: The Cisco Nexus 9300-EX/FX/FX2/FX3/GX platform switches do not support Multiple ACL filters on the same source. SPAN is supported in Layer 3 mode; however, SPAN is not supported on Layer 3 subinterfaces or Layer 3 port-channel subinterfaces. SPAN sources include the following: Ethernet ports Precision Time Protocol with hardware Pulse-Per-Second port: The Cisco Nexus 3548 supports PTP operations with hardware assistance. The port GE0/8 is where the user device is connected. SPAN has the following configuration guidelines and limitations: Traffic that is denied by an ACL may still reach the SPAN destination port because SPAN replication is performed on the ingress By default, the session is created in the shut state. You can configure only one destination port in a SPAN session. Multiple ACL filters are not supported on the same source. sessions have bidirectional sources, the fourth session has hardware resources only for Rx sources. This example shows how 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. multiple UDFs.
