Hi Claudio,
1. LiSA compilation
I didn't touch the variable. Below is the content of Makefile.variables.
ifndef IMPL
#IMPL = lisa
IMPL = linux
#IMPL = openwrt
endif
I tried to change the content of the file as following but they are
errors during compilation. Please check the attachment.
ifndef IMPL
IMPL = lisa
#IMPL = linux
#IMPL = openwrt
endif
2. Ethernet interfaces
The interface eth0 was up when I tried to configure it.
box(config)#interface ethernet 0
Command rejected: interface eth0 does not exist
box(config)#interface ethernet 0
box(config-if)#description test
box#show running-config interface ethernet 0
Building configuration...
Current configuration : 103 bytes
!
interface Ethernet 0
description test
switchport trunk allowed vlan 1-4094
switchport mode access
end
As you can see, interface description is saved to running-config. We can
normally configure interface but first time is an interface configured.
the warning message is displayed "Command rejected: interface eth0 does
not exist"
Cheers,

Hello,
Thank you for your feedback regarding the functionality of LiSA.
The first 4 problems will be dealt with as soon as possible. The
5th reported issue is not actually a problem because you should
definitely have root privileges when configuring the hostname.
The same for the other operations (bridge and interface
configurations).
Could you also tell us please if you changed the back-end
implementation in "userspace/scripts/Makefile.variables"? The
default one is using the two Linux kernel modules, bridge and
8021q, and this option can be changed through the "IMPL"
variable in the above mentioned file.
Regarding the third issue, I personally checked yesterday the
same command. I was able to configure an Ethernet interface on
my system. Could you confirm please that the interface was up
when you tried to configure it?
Have a nice day!

Hello team,
I have my Qemu image with installed Core Linux 5.0
(3.8.10) ready. I successfully compiled LiSA Devel
version available on git (26.9. 2013).
I'm not going to send LiSA extension to Core repository
until it proves that basic configuration is working -
swiching, vlan, trunks etc.
I used command sudo swcli for LiSA configuration and
notice the following problems:
1. running-config
all the vlans - from 2 to 4093 are presented in a
running-config, each on separate line. I guess, VLANs
should haven't be presented in running-config because no
vlan had been created so far. And it is annoying e.g. if
you want to check interface configuration in
running-config you have to go through all the vlans. It
is because interface configuration is displayed after
vlan configuration.
test#show run
Building configuration...
Current configuration : 48025 bytes
!
hostname test
!
!
no ip igmp snooping
!
vlan 2
!
vlan 3
!
vlan 4
.
.<output truncated>
.
!vlan 4093
interface Ethernet 0
description test
switchport trunk allowed vlan 10
switchport mode trunk
2. VLANs are not presented in show vlan command
when I create VLAN, I should get in (config-vlan) prompt
and configure vlan name. Instead of it I get back to the
prompt (config)#
box(config)#vlan 10
box(config)#
VLAN 10 is not presented in show vlan command.
test#show vlan
VLAN Name Status Ports
---- -------------------------------- ---------
-------------------------------
test#
3. Ethernet interface configuration
test(config)#interface ethernet 0
Command rejected: interface eth0 does not exist
test(config)#
test(config)#
test(config)#interface ethernet 0
test(config-if)#
First, it was complaining that ethernet 0 doesn't exist.
But the second time I was able to get in to (config-if)
prompt and normally configure switchport parameters such
as trunk, allowed vlan etc.
4. VLAN interface configuration
VLAN interface can't be configure. Please, see the
output below.
test(config)#interface vlan 20
Command rejected: ioctl() failed (19 - No such device)
test(config)#
5. running swcli without root privilegies
I\m not sure if it is a desired option or not but when
you start swcli as a normal user (no root) you can't
configure hostname.
test(config)#hostname switch
Command rejected: Operation not permitted
test(config)#
So far I haven't tested if switching is working. First I
must create a LiSA binary extension and then I can test
LiSA against other devices inside GNS3. But first the
mentioned problems should be fixed. I hope I compiled
LiSA properly. The output of make and make install
command is attached. Thank you.

Hi,
I've managed to get the devel branch compile
properly, but there seems to be something wrong
with the "bridge+8021q" backend - which is what
we want to use in order to avoid patching the
kernel. I've already posted the issue to the
devel list, so the developer who wrote that
module may have a chance to investigate what's
going on.
Anyway, I still want to port the kernel module
to newer kernels. If I succeed, then perhaps we
can use the "stable" version and the patched
kernel, and then make an update when the "devel"
version is fixed.
Thanks,
Radu
