You have ProxySG or Advanced Secure Gateway (ASG) configured on a network with Cisco Routers

You have Cisco Routers which support Encapsulated Remote Switch Port ANalyzer (ERSPAN).

You want to know if ProxySG or ASG support ERSPAN.

Neither the ProxySG nor the ASG support Cisco's proprietary ERSPAN protocol. Please contact your sales team to submit a Feature Request if you desire support for this feature.
