Creates an IPv4 access control list (ACL) and enters IP access list configuration mode. Its also a two stage setup process, you have to define your monitoring ports first and then configure your monitoring sessions. The third mode enables fabric extension to a Nexus 2000. This example shows how to configure UDF-based SPAN to match regular IP packets with a packet signature (DEADBEEF) at 6 bytes Doing so can help you to analyze and isolate packet drops in the source interface If the traffic stream matches the VLAN source Tx SPAN of CPU-generated packets is not supported on Cisco Nexus 9200 platform switches. 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. configure one or more sources, as either a series of comma-separated entries or the following match criteria: Bytes: Eth Hdr (14) + Outer IP (20) + Inner IP (20) + Inner TCP (20, but TCP flags at 13th byte), Offset from packet-start: 14 + 20 + 20 + 13 = 67.
