Hi !

I’m staging a RARE/freeRtr in California :)
I’ve an observation WRT bringing up interface:


interface sdn30
 lldp enable
 vrf forwarding CORE
 ipv4 address 10.10.30.1 255.255.255.0
 no shutdown
 no log-link-change
 exit


When applying:

server p4lang p4
 ...
 export-port sdn30 280 100 2 1 0
 ...
 exit

I see on the debug server p4 [rx/tx/err] the following message:
...
debug servP4langConn.doReports:servP4lang.java:2288 rx: dataplane-say 
Attempting to set administrative state for inactive port [280]
info servP4langConn.doReports:servP4lang.java:2821 dataplane said: Attempting

debug servP4langConn.doReports:servP4lang.java:2288 rx: dataplane-say 
Attempting to set mtu for inactive port [280]
info servP4langConn.doReports:servP4lang.java:2821 dataplane said: Attempting 
to set mtu for inactive port [280]
…

When I check bfshell the interface is _NOT_ enabled at the dataplane level:
In the output 30/0 entry is missing.

In freeRtr the interface is showed as "UP"

In order to bring it up I had to enable it manually at the dataplane level.

After enabled manually the port appears.
(In this case it is still down but this will be tuned at a later stage)

At that moment the port is showed as "DOWN"

The switch is a Wedge100BF 32QS.

All the best,
