[LiSA-Users] vlan interfaces are generated with the same MAC addresses

[chicany]

Hi,

thank you for your response. I have a new update regarding my issue:

1.
Today I was able to change MAC address for VLAN interface. It works
perfectly in both cases - when I load switch module with vif_mac parameter
and also as when I add a line vif to /etc/modprobe.d/lisa.conf. Sorry for
confusing you last time I don't really know when I made a mistake during my
tests.

2.
Seems that the last two hexa numebers are changed for vlan interface. For
example, when vif_mac is 02:00:11:22:33:42 the MAC adress of VLAN
interface30  is e.g. 02:00:11:22:33:6A. I'm ok with it but I have another
question.  Cisco allows to change MAC address of particular interface under
interface configuration. Would it be possible to implement this command at
least for VLAN interfaces?

3.
I noticed even the ping and traceroute commands are available in the enabIe
mode they are not working.  For instance:

QEMU2#ping 192.168.1.2
           ^
% Invalid input detected at '^' marker.

For this reason I must exit LiSA when everytime those commands are needed.
Sorry, I should have brought this to a new topic but it is really annoying
;)

Thank you.
