LanView 4 and VLANs

[timbo343]

Does anyone know how to get LanView4 to talk over different VLANs?

 

I am able to get the server and client talking in the same VLAN but as soon as the server is is a different VLAN on the same switch, it doesnt work.

 

Thanks

I have been trying to get this to work, but with not a lot of success...

 

However, what I have been able to get working is to have two network cards in my PC. One card is on the main LAN and the other card is plugged in to our VLAN.

 

That allows me to toggle between network connections and to view the two sets of machines (separately) via Lanview4.

 

This, of course, is only any good if you only have a single VLAN, as multiple VLANS would require multiple additional network cards and connections to your PC.

 

Not ideal, but it is working ok for me at the moment. Just thought I would share...

 

Have you been able to find any other solutions to the VLAN issue?

I found the way during the easter break..

 

We have HP switches and i had to add IP FORWARD-PROTOCOL UDP {BROADCAST ADDRESS OF THE VLAN} {PORT}. Here is the config from one of our switches which was acting as the core switch in the test VLAN.

 

Port 2104 is the sending port to the clients and port 2607 returns the status of the client. My admin machine was in VLAN1, client machines were in VLAN2 & 3 and it worked without any problems..

 

vlan 1
  name "DEFAULT_VLAN"
  untagged 14-21,23-24
  ip address 10.0.0.2 255.255.255.0
  ip helper-address 10.0.0.254
  ip forward-protocol udp 10.0.3.255 2104
  ip forward-protocol udp 10.0.2.255 2104
  ip forward-protocol udp 10.0.4.255 2104
  ip forward-protocol udp 10.0.5.255 2104
  ip forward-protocol udp 10.0.6.255 2104
  ip forward-protocol udp 10.0.7.255 2104
  ip forward-protocol udp 10.0.8.255 2104
  ip forward-protocol udp 10.0.9.255 2104
  ip forward-protocol udp 10.0.10.255 2104
  ip forward-protocol udp 10.0.11.255 2104
  ip forward-protocol udp 10.0.12.255 2104
  ip forward-protocol udp 10.0.13.255 2104
  ip forward-protocol udp 10.0.14.255 2104
  ip forward-protocol udp 10.0.15.255 2104
  ip forward-protocol udp 10.0.16.255 2104
  tagged 22
  no untagged 1-13
  exit
vlan 2
  name "VLAN2"
  ip address 10.0.2.1 255.255.255.0
  ip helper-address 10.0.0.254
  ip forward-protocol udp 10.0.0.255 2607
  tagged 21-22
  exit
vlan 3
  name "VLAN3"
  untagged 9-12
  ip address 10.0.3.1 255.255.255.0
  ip helper-address 10.0.0.254
  ip forward-protocol udp 10.0.0.255 2607
  tagged 21-22
  exit

 

Since the HP Switches we have got only allow 16 entries and we wanted to have about 26 VLANS then we decided to go against it, to this day im looking for a switch which will flood VLANs with the IP FORWARD setting.

I found this on the MST Software site, which may help anyone with CISCO switches:

 

"It is possible by setting up on a cisco device:

 

ON THE SENDING SUBNET

 

ip helper-address SUBNET-BROADCAST-ADDRESS ie 192.168.1.255

 

// This turns the 255.255.255.255 lanview broadcasts to a directed broadcast

 

IN GLOBAL CONFIG

 

ip forward-protocol udp 2607

ip forward-protocol udp 2104

 

// This allows the IP helper address to forward broadcast UDP packets on those ports

 

create an ACL for filtering so only wanted directed broadcasts are forwarded:

 

access-list 110 permit udp host LANVIEWSERVERIP any eq 2607

access-list 110 permit udp host LANVIEWSERVERIP any eq 2104

 

on the recieving subnet

 

ip directed-broadcast 110

 

On a layer 3 switch these are applied to the VLAN interfaces.

 

And DONE!

 

PS Dont blame me if you break stuff!"

 

 

Please let me know if anyone has any other info. for CISCO switches.
