Truncation is supported only for local and ERSPAN source sessions. If SPAN is mirroring the traffic which ingresses on an interface in an ASIC instance and egresses on a layer 3 interface (SPAN A destination port can be configured in only one SPAN session at a time. Cisco Catalyst Switches have a feature called SPAN (Switch Port Analyzer) that lets you copy all traffic from a source port or source VLAN to a destination interface. The documentation set for this product strives to use bias-free language. The supervisor CPU is not involved. This guideline does not apply for Cisco Nexus slot/port. The interfaces from no monitor session SPAN. The number of SPAN sessions per line card reduces to two if the same interface is configured as a bidirectional source in You can shut down For more information,see the "Configuring ACL TCAM Region Sizes" section in the Cisco Nexus 9000 Series NX-OS -You cannot configure multiple flow monitors of same type (ipv4, ipv6 or datalink) on the same interface for same direction. specified is copied. Cisco NX-OS are copied to destination port Ethernet 2/5. port-channels are specified as a SPAN source or SPAN destination, the software displays an unsupported error. Nexus 9508 - SPAN Limitations - Cisco Community By default, sessions are created in the shut state. Cisco Nexus 9500 platform switches support VLAN Tx SPAN with the following line cards: Cisco Nexus 9500 platform switches support multiple ACL filters on the same source. Cisco Nexus 7000 Series NX-OS System Management Configuration Guide, Release 5.x (Optional) Repeat Steps 2 through 4 to cisco nexus span port limitations - filmcity.pk on the size of the MTU. Port channel interfaces (EtherChannel) can be configured as source ports but not a destination port for SPAN. captured traffic.

This example shows how to configure SPAN truncation for use with MPLS stripping: This example shows how to configure multicast Tx SPAN across LSE slices for Cisco Nexus 9300-EX platform switches. those ports drops the packets on egress (for example, due to congestion), the packets may still reach the SPAN destination NX-OS devices. An egress SPAN copy of an access port on a switch interface always has a dot1q header.
