syslog message with invalid subnetmask

[vemulabalaji]

Hi,

On trying to configure an IP address using ifconfig command, i am observing syslog message with different subnet mask.

I am working on Mellanox target.

root@test-bed-1:/etc/sonic# show version
SONiC Software Version: SONiC.HEAD.794-c61c1d5
Distribution: Debian 9.6
Kernel: 4.9.0-7-amd64
Build commit: c61c1d5

I executed below command.

ifconfig Ethernet56 13.13.13.13/24 up

But i observed log messages with 13.13.13.13%23 and 13.13.13.13/8
After configuring "ifconfig Ethernet56" is showing configured IP address only.
But why are we observing these messages.
Can some one explain it.

on the master branch, could you use the command config interface <interface_name> ip add <ip_address>?
