[Priya-NS]

SYMPTOM

SONiC AS5712 : "show interface status " is throwing error.

TOPOLOGY

AS5712 DUT

STEPS TO REPRODUCE

1. Bring Up the DUT with default configuration and with the latest build SONiC.201811.0-38d0051
2. Execute the command "show interface status " in AS5712. Observe that it is throwing error.

root@SONIC:~# show interfaces status Ethernet39
Traceback (most recent call last):
File "/usr/bin/intfutil", line 204, in
main(sys.argv[1:])
File "/usr/bin/intfutil", line 197, in main
interface_stat = IntfStatus(intf_name)
File "/usr/bin/intfutil", line 129, in init
appl_db_keys = appl_db_keys_get(self.appl_db, intf_name)
File "/usr/bin/intfutil", line 41, in appl_db_keys_get
appl_db_keys = db.keys(appl_db.APPL_DB, "PORT_TABLE:%s" % intf_name)
NameError: global name 'db' is not defined

EXPECTED BEHAVIOR:

1. As per the Help text, the command should work.
   root@SONIC:~# show interfaces status flejwlfj kjflew
   Usage: show interfaces status [OPTIONS] [INTERFACENAME]

Error: Got unexpected extra argument (kjflew)
2. The same command is working in other SONiC DUT of AG9032v1.

It needs a bug fix in intfutil script in the function app_db_keys_get() function when getting the keys for a specific interface.
I am submitting Pull Request for this shortly.
