This is a Port Mirror implementation across two Juniper EX9208 switches (Remote port mirror scenario)
Traffic from production VLANs on the source switch is mirrored into a dedicated remote monitoring VLAN (Vlan 100 )and transported via an aggregated trunk link (AE0) to a Destination-Switch for packet analysis.
On the Destination-Switch I have a packet capture device connected to port xe-0/0/0 capturing traffic on Vlan 100
The mirrored frames are not successfully egressing to the capture tool.
Configuration on the Source-Switch:
set forwarding-options analyzer Remote-Analyzer input ingress vlan vlan_50
set forwarding-options analyzer Remote-Analyzer input ingress vlan vlan_60
set forwarding-options analyzer Remote-Analyzer output vlan vlan_100
set interfaces ae0 unit 0 family ethernet-switching interface-mode trunk
set interfaces ae0 unit 0 family ethernet-switching vlan members all
Configuration on the Destination-Switch:
set forwarding-options analyzer Remote-Analyzer input ingress vlan vlan_100
set forwarding-options analyzer Remote-Analyzer output interface xe-0/0/0.0
set interfaces xe-0/0/0 unit 0 family ethernet-switching interface-mode trunk
set interfaces xe-0/0/0 unit 0 family ethernet-switching vlan members vlan_100
.
Remove trunk and vlan configuration from the xe-0/0/0 interface.Output interface should only be configured with "unit 0 family ethernet-switching"
#delete interfaces xe-0/0/0 unit 0 family ethernet-switching interface-mode trunk#delete interfaces xe-0/0/0 unit 0 family ethernet-switching vlan members vlan_100
Instead do:#set interfaces xe-0/0/0 unit 0 family ethernet-switching
