ESX 6.0 and onwards DOES support ERSPAN which is an extension to GRE and includes Cisco additions such as Vlan tag and Span ID. Eliminating possible causes is an important step in the troubleshooting process and there are a couple of approaches how you can do this, here they are: Top-down. This chapter focused on various NX-OS tools that can be used to troubleshoot complex problems. Troubleshooting EVPN Type-2 Route Advertisement. Using ERSPAN tunnel decapsulation, GigaSMART can act as the receiving end of an ERSPAN tunnel, decapsulating mirrored traffic sent over the Internet from a Cisco switch or router. Summary. Summary. Candidates are expected to program and automate the network within their exam, as per exam topics below. You can directly send SPAN traffic to a PC running on wireshark (even without configuring ERSPAN destination on another switch). Nexus switches are among the most powerful data center switches in the industry. Encapsulated remote SPAN (ERSPAN): encapsulated Remote SPAN (ERSPAN), as the name says, brings generic routing encapsulation (GRE) for all captured traffic and allows it to be extended across Layer 3 domains. draft-foschiano-erspan-00. Cisco Nexus 1000V Troubleshooting Guide, Release 4.0(4)SV1(1) OL-19427-05 Chapter 15 SPAN Troubleshooting SPAN Problems Troubleshooting SPAN Problems When troubleshooting issues with SPAN, make sure you have followed these configuration guidelines and limitations: † A maximum total of 64SPAN and ERSPAN sessions can be configured per VSM.
