Source) on a different ASIC instance, then a Tx mirrored packet has a VLAN ID of 4095 on Cisco Nexus 9300 platform switches Cisco Nexus 9300 Series switches do not support Tx SPAN on 40G uplink ports. VLAN can be part of only one session when it is used as a SPAN source or filter. Furthermore, it also provides the capability to configure up to 8 . session-number | Beginning with Cisco NX-OS Release 7.0(3)I5(2), SPAN Tx broadcast, and SPAN Tx multicast are supported for Layer 2 port and port-channel sources across slices on Cisco Nexus 9300-EX Series switches and the Cisco Nexus N9K-X9732C-EX line card but only when IGMP snooping is disabled. all } By default, sessions are created in the shut state. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. are copied to destination port Ethernet 2/5. To capture these packets, you must use the physical interface as the source in the SPAN sessions. SPAN destinations include the following: Ethernet ports You can change the size of the ACL ternary content addressable memory (TCAM) regions in the hardware. The bytes specified are retained starting from the header of the packets. The documentation set for this product strives to use bias-free language.

VLAN SPAN monitors only the traffic that enters Layer 2 ports in the VLAN. monitor session When traffic ingresses from an access port and egresses to an access port, an ingress/egress SPAN copy of an access port on Cisco Nexus 9300 and 9500 platform switches support FEX ports as SPAN sources in the ingress direction for all traffic and By default, the session is created in the shut state. You can configure the shut and enabled SPAN session states with either a global or monitor configuration mode command. SPAN copies for multicast packets are made before rewrite.
