1. fix the issue which "when" doesn't work when it is in a nested "block" statement 2. don't use the hardcoded "Ethernet0" since in topo t1-lag it belongs a PortChannel and to set ip address on such kind of interface causes orchagent terminated. choice a valiable routed interface for test instead. [show_interface.py] 1. add "vlan" to int_status dict
don't use an ary/neighbour which is a bgp neighbour to do the updating neighbour's mac test, doing in that way can cause bgp connection down and a large number of routing entries withdrawed, failing orchagent to handle neighbour mac update in time. use a newly added address and neighbor on an automatically selected routing interface for that test instead.
…hose oper_state are 'up' and remove startup interface stuffs
1. fix the issue which "when" doesn't work when it is in a nested "block" statement 2. alway use a static arp/neighbour for testing, since the dynamic entries are of the BGP neighbors and to change their mac address causes bgp neighbour down and route withdrew, making system busy and unable to handle mac update in time. we use Ethernet0 for t0 and t1, PortChannel0002 for t1-lag

This reverts commit 181a522.
dynamically choose an interface from the output of show interface status which meets the following conditions for the test: 1. it is a routing interface 2. it is up. [show_interface] add support for the "vlan" column.

@stephanxs, I see that the test now uses 'vlan' interface. But this is not present in t1 topologies. How does it work on t1 topology? |

hi Prince, it doesn't choose a vlan interface to do the test. it choose an interface which satisfies both 'up' and 'routed interface' on the dut. |

Description of PR
Summary:
Fix issue 2414 by always using static arp/neighbour entry for the neighbour-mac-noptf testcase
Type of change
Approach
How did you do it?
we choose an interface meeting 1. routing interface 2. oper_state is up from the output of "show interface status" for the test.
How did you verify/test it?
run the testcase on t0, t1 t1-lag and ptf32
Any platform specific information?
Supported testbed topology if it's a new test case?
