[j-nsp] Port Mirroring on EX series

[Abdullah Baheer]

Hi
I have a customer who will be testing some mirroring features. I provided them with the steps to configure mirroring on an EX-4200 switch running 12.1, but they are getting an error.
box# commit checkerror: Interface ge-0/0/46.0 has conflicting memberships configured under interfaces stanza and vlan stanzaerror: configuration check-out failed
The Juniper guide they are using is on the link:http://www.juniper.net/documentation/en_US/junos12.3/topics/example/port-mirroring-remote-ex-series.html


Here’s the config they are trying to commit: [edit interfaces]+   ge-0/0/46 {+       unit 0 {+           family ethernet-switching {+               port-mode trunk;+               vlan {+                   members 999;+               }+           }+       }+   }[edit ethernet-switching-options]+   analyzer exa-test {+       loss-priority high;+       input {+           ingress {+               interface ge-0/0/27.0;+           }+           egress {+               interface ge-0/0/27.0;+           }+       }+       output {+           vlan {+               999;+           }+       }+   }[edit vlans]+   SPAN-test {+       vlan-id 999;+       interface {+           ge-0/0/46.0 {+               egress;+           }+       }+   }
My first reaction is to remove the vlan configuration from the hierarchy of the interface ge-0/0/46, but this would mean telling the customer that the juniper documentation has an error, so I need to be sure that this would solve the problem. I don't have an EX switch to test it for myself.I highly appreciate if anyone has done this or can test it for me.

ThanksAbdullah
