network segment use vlan, linux vconfig and AT-GS950
Dear all,
I have a Allied Telesyn AT-GS950 16 port switch.
All hosts&router have rtl8139 NICs.
OS : Slackware linux 12.1.
I use a switch with vlan technique to separate my network to some segment.
here my plan:
router eth0 ---> switch port 1
switch port 5 <--- eth0 host A
switch port 6 <--- eth0 host B
in eth0 of router, I make two vlan :
host A :
host B :
Arrange vlan configuration in switch :
ping result to both host A and host B from router gave same result : Destination Host Unreachable
ping command :
Please help, there's maybe I have wrong concept about vlan configuration?
Thank you very much.

All config seems to be ok. Check ping from host to router (in same network, 172.16.5.2 -> 172.16.5.1 etc). Check running router process on router. And check trunk mode on AT switch - it must be 802.1q (dot1q).
Additionaly try to disable firewall on router, if you use that

Hi,
Is it possible to VLAN tag with a ce interface on Solaris 9? Link speed is gb.

What commands would I need to run?
Thanks.;) (2 Replies)
