Description

test_sub_port_interfaces.py failed.

Steps to reproduce the issue:

  1. config a sub-interface on the device: Ethernet12.10
root@str2-7050cx3-acs-01:/tmp# config vlan member del 1000 Ethernet12

  1. add the interface Ethernet12 back to Vlan1000, then do the sub-steps as step 3
  • add the interface to Vlan1000 then ping from DUT, ping is OK.
