RE: One ethernet card, two IP address, two VLAN

[jsilberberg@xxxxxxxxxxxxxx]

Guys, 

    I think the "network" guys need to rethink what they are asking.  To my 
understanding a VLAN is a network object not a device object and as such is not 
be defined on the iSeries.  

    Also, to pass traffic between two IP Subnets that are VLAN seperated you 
need a router somewhere in the mix.  Now the iSeries can, if allowed, route 
traffic bewteen subnets but except in the case of virtual networks between 
LPARs I can't see why anyone would want to do this..

    As a reference point your people to the CISCO Catalyst 4000 Manual.

"VLANs are often associated with IP subnetworks. For example, all of the end 
stations in a particular IP subnet belong to the same VLAN. Traffic between 
VLANs must be routed. LAN interface VLAN membership is assigned manually on an 
interface-by-interface basis. When you assign LAN interfaces to VLANs manually, 
it is known as interface-based or static VLAN membership."

   I too would like to see there Windows example if they do it all the time in 
Windoze..

   JMS..

PS:  There is a concept of a secondary VLAN assignment but this is also a 
finction of the Network Hardware not the Device attached..

Just for my own education, is there any chance you can get them to explain how 
this would be done under Windows? (I've had enough trouble getting two 
physically separate interfaces working at times.)

p.s. Yes, I realize this reply isn't exactly "Midrange"; but if a Windows 
procedure is given, maybe someone will recognize a possibility for OS/400.
