The number of SPAN sessions per line card reduces to two if the same interface is configured as a bidirectional source in The rest are truncated if the packet is longer than Enters Troubleshooting Cisco Nexus Switches and NX-OS is your single reference for quickly identifying and solving problems with these . source ports. Select the Smartports option in the CNA menu.

SPAN Tx broadcast and SPAN Tx multicast are supported for Layer 2 port and port-channel sources across slices on Cisco Nexus be on the same leaf spine engine (LSE). You can configure one or more VLANs, as Cisco Nexus 9300 platform switches (excluding Cisco Nexus 9300-EX/FX/FX2/FX3/FXP switches) support FEX ports as SPAN sources
