Inter VLAN routing on Omniswitch 6400

Posted: 21 Oct 2011 06:25
by Support ACA
I am new on this forum, but other posts have already been lots of help to me.

I have a problem with our network where data VLAN 1 cannot talk to voice VLAN 221. I thought the Omniswitch 6400 would automatically do (layer 3?) inter vlan routing. Some other threads seem to suggest this should work just fine out of the box. If I need to buy a layer 3 router, I will do so. If I can avoid it, this would make me extremely happy.

The network I have looks something like this:

Currently, the DATA network can talk fine to other members in the DATA network, and can talk to the internet through the Sonicwall NSA2400 firewall.
Currently, the VOICE network can talk fine to other members in the VOIP network, and can talk to the internet through the Sonicwall NSA2400 firewall.

Another strange thing is that I was able to talk from a PC in the data network to a server and a phone in the VOIP network and the other way around. To be sure, all configurations were written to starting configurations and Alcatel stack and switch was rebooted. Then it stopped working again. I document every change I make, so normally changes do not go lost.

After these issues I even added the latter config tot the 6400, to no avail

Hi,
I understand you need to ping from data to voip and vice versa.
Normally your OS6400 routed traffic between both vlans based on

Code: Select all

ip static-route 10.132.3.0/24 gateway 10.132.3.253 metric 1
ip static-route 10.221.17.0/24 gateway 10.221.17.253 metric 1
Also you no needed the static-routes in your config and qos policies(traffic is already accepted).
Before reboot do "write memory flash-synchro" for config synchronization in stack.
I do not see default route to FW on 6400, hence another routing done on your Sonicwall?

Thank you for all hints and tips. Especially the synchro, I did not know one has to do that.

GOAL

My goal is (still) that Desktop PC's in VLAN 1 (network 10.132.3.0/24) can "talk" to the VOIP phones in VLAN 221 (network 10.221.17.0/24).
I believe there to be a need to do that, for tasks such as: A person on a desktop PC wants to transfer a call from a VOIP phone to another persons VOIP phone.

WHAT I CHANGED

After installation of the "enhanced" firmware on the Sonicwall, I found that the Enhanced OS for Sonicwall CAN handle VLANs and trunking on one port. So, as can be seen in the picture (URL https://docs.google.com/drawings/d/1mu0 ... -4cLo/edit ), I now have a VLAN 221 sub-interface "X0:v221" on the VLAN 0 interface "X0" (VLAN 0 is supposedly more or less the same as VLAN 1).

Of course, my port 1/10 on the Omniswitch 6400 Core switch, is now trunked and goes to the Sonicwall X0. The other port OS6400 1/11 to Sonic X2 has been disconnected.

I also changed a little bit of the routing stuff on the 6400 and the LS6442P

THE GOOD (improvements since my previous post)

1. I can now ping from my desktop PC (10.132.3.32) to any device in VLAN 221, such as voip phone 10.221.17.50
2. I can now ssh and https from my desktop PC (10.132.3.32) to the Sonicwall management interface on VLAN 221 with IP 10.221.17.253
3. From within the sonicwall ssh, I can reach all devices in both networks.

THE BAD

1. I can reach the VOIP server 10.221.17.212 with TELNET when I am logged in to the cli in the 6400 and the cli in the 6224P, but I cannot reach it with telnet NOR ping from my desktop PC. The VOIP server does have two interfaces on a windows machine. The other interface of this Windows server is 10.132.3.212 with default router 10.132.3.253 (a Windows machine can only have one default router per machine).
2. From my Desktop PC 10.132.1.32, I can NOT telnet to 10.221.17.194 (Alcatel 6400 in VLAN 221) NOR the 10.221.17.193 (Alcatel 6224P in VLAN 221). ( I have put my PC in VLAN 221 with DHCP and then I could telnet to the Alcatels)

CONCLUSION

So, it seems now that I can PING everywhere from my Desktop PC, but I cannot TELNET to anything in VLAN 221. I have not found any firewall exceptions in the Sonicwall that would prevent TELNET traffic.

Does anyone know if I am missing something in my Alcatel configuration that would prevent such?
Are there still errors in my Alcatel routing statements?

Sorry, overwritten,
of course routed based on

Code: Select all

ip interface "data" address 10.132.3.194 mask 255.255.255.0 vlan 1 ifindex 1
ip interface "voip" address 10.221.17.194 mask 255.255.255.0 vlan 221 ifindex 2
