Hi VPP-devs,
I was recently testing interface dump and I noticed that it returns weird value
for link_speed. I tested both Java API and Python API for VPP together with
console output.
When I called sudo vppctl sh hardware in console I get:
Name Idx Link Hardware
GigabitEthernet0/9/0 1 down GigabitEthernet0/9/0
Link speed: 1 Gbps
Ethernet address 08:00:27:04:6e:c0
...
Which says that link speed is 1Gbps. When I try this using Java API or Python
API I get a value of 1078071040.
Part of python script which returns the result:
...
for intf in vpp.api.sw_interface_dump():
print(intf.interface_name.decode() + ", link speed:" + str(intf.link_speed))
...
Output:
local0, link speed:0
GigabitEthernet0/9/0, link speed:1078071040
The provided value should be in kbps according to documentation for API:
define sw_interface_details
...
/* link speed in kbps */
u32 link_speed;
Is this value in bps or kbps? Should it be divided (1Gbps should be 1 000 000
000bps) and rounded? Or is this a bug?
Thanks Michal
