M4100-50G-POE+ sFlow with PRTG. Has anyone done this?
M4100-50G-POE+ sFlow with PRTG. Has anyone done this? M4100-50G-POE+ ProSafe 48-port Gigabit L2+ Intelligent Edge PoE Managed Switch, 10.0.1.16, B1.0.0.9 When I setup the M4100 to have this ...
Hi nsskyetech,
The "#show ip interface brief" returns empty because there is no routing interface configured. Routing interface is needed to configure the sFlow source-interface. You can either use a VLAN routing interface or physical routing interface.
Please see below commands on how to configure VLAN routing interface in CLI:
# vlan database
(vlan)# vlan routing 1
(vlan)# exit
#config
(config)#interface vlan 1
(Interface-vlan 1)#ip address 172.16.121.55 255.255.255.0
(Interface-vlan 1)#exit
To use this VLAN routing interface as the sFlow Agent Source Interface, please see command below:
#config
(config)#sflow source-interface vlan 1
Please see below links for additional information:

enabled vlan routing
next to set the vlan ip interface
(M4100-50G-POE+) #config
(M4100-50G-POE+) (Config)#interface vlan 1
(M4100-50G-POE+) (Interface vlan 1)#ip address 172.16.121.55 255.255.255.0
vlan 1
Subnet conflict between specified IP Address and current configuration.
All routing interfaces, service ports and network ports must be configured on different subnets. (M4100-50G-POE+)- can't seem to use my subnet, so used another subnet/ip that is not on my network
(Interface vlan 1)#ip address 192.168.121.55 255.255.255.0
(M4100-50G-POE+) (Interface vlan 1)#exit
(M4100-50G-POE+) (Config)#sflow source-interface vlan 1
(M4100-50G-POE+) (Config)#exit
(M4100-50G-POE+) #show ip interface brief
Interface State IP Address IP Mask Method---------- ----- --------------- --------------- -------
vlan 1 Up 192.168.121.55 255.255.255.0 ManualGreat but this doesn't seem to be proper.
removed the vlan interface ip address.
---
set the receiver configuration (to the PRTG IP) in the web gui & the sflow interface configuration
NOW PRTG can get sflow information from the M4100 switch
- I think it was just the 'vlan routing' being enabled.
Thanks for all you help
Just a pain that the docs don't have this info clarified
