RSPAN to vmware not working
Hello
We have a stack of two M4300s. I want to span two LAG ports to RSPAN vlan and monitor this on destination on vmware distributed switch.
I followed following video to set up vmware part.

Relevant netgear config is below.
vlan name 1514 "RSPAN"
vlan 1514
remote-span
port-channel name lag 1 FW01
interface 1/0/1
addport lag 1
exit
interface 2/0/1
addport lag 1
exit
port-channel name lag 2 FW02
interface 1/0/2
addport lag 2
exit
interface 2/0/2
addport lag 2
exit
interface 1/0/31
description 'ESX'
vlan participation include 1100-1101,1103-1104,1113-1114,1254,1514
vlan tagging 1,1100-1101,1103-1104,1113-1114,1254,1514
exit
interface 2/0/31

My issue is that I see no traffic on vlan 1514 on vmware distributed switch. When select other vlans as source under vmware distributed switch, I do see traffic so this points me to some issue between netgear and vmware.
We use similar netgear setup on other M4300 stack, but destination is physical port and this is working fine.
Any idea what can this be and how to fix this?
Many Thanks.

No fix possible - this is very likely a imitation. A mirror port can't be a LAG.
Hello
On our other stack we have following working ok. Only difference is that destination is not RSPAN vlan, but physical port.
port-channel name lag 1 TO-FW01 interface 1/0/1 addport lag 1 exit interface 2/0/1 addport lag 1 exit port-channel name lag 2 TO-FW02 interface 1/0/2 addport lag 2 exit interface 2/0/2 addport lag 2 exit monitor session 1 destination interface 2/0/48 monitor session 1 source interface lag 1 monitor session 1 source interface lag 2 monitor session 1 modeI changed config on problematic stack to following(to get some traffic from physical ports not LAG) and it's still not sending traffic to VLAN 1514.
vlan 1514 remote-span monitor session 1 destination remote vlan 1514 reflector-port 1/0/48 monitor session 1 source interface 1/0/25 monitor session 1 source interface 2/0/25 monitor session 1 mode
