please try restarting contrail-snmp-collector and contrail-topology - if you

Hi all,

I am running Contrail 2.21 un ubuntu 14.04 and try to get started with 
Underlay/Overlay Mapping. I followed the instructions from the documentation:

http://www.juniper.net/techpubs/en_US/contrail2.21/topics/task/configuration/underlay-overlay-mapping-vnc.html

I have a setup with three Juniper EX switches and configured them for SNMP and 
sflow. I also added them as "physical routers" in the Contrail GUI along with 
their SNMP community. Tcpdump on the contrail server shows me that sflow is 
been recieved from all switches. SNMP queries by contrail are answered by all 
three switches.

When I check these switches at:

http://<ip>:8081/analytics/uves/prouter/<switchname>?flat

two look like this:

{"UvePhysicalRouterConfig": {"product_info": ":", "auto_conf_enabled": false, 
"netconf_enabled_status": false, "ip_address": "172.24.1.154"}}

The third one is acutally showing the interfaces of the switch. When I check 
the switches in the GUI, none of them shows any interfaces. Additionally I am 
not able to find the following menu point in the GUI as mentioned by the 
documentation:

"The topology view and related functionality is accessed from the Physical 
Topology link in the Monitor tab of the Contrail user interface, Monitor > 
Physical Topology"

There is no such point in my GUI under "Monitor". I saw some screenshots from 
opencontrail.org, where this point is located between "Dashboard" and "Control 
Nodes" but it is not there on my installation.

Any idea how I could move on? The services seem to run:

$ sudo service contrail-topology status
contrail-topology                RUNNING    pid 2032, uptime 14:46:09
$ sudo service contrail-snmp-collector status
contrail-snmp-collector          RUNNING    pid 2031, uptime 14:46:46

Thanks

Sebastian
