There are managed switches, and then there are routing switches. Managed simply means there is a processor on the box that can manage some aspect of the switch; in some cases this is as simple as being able to turn ports on and off and reset the switch. Routing switches employ virtual routers to route between the VLANs managed by the switch. The usual way to do this is to assign an IP address to the virtual router in the "normal" IP address range of each VLAN. The router then routes between these virtual interfaces in the normal manner. I can't speak to the insides of the HP equipment, but Xylan/Alcatel used a modified version of the Net/2 TCP/IP stack running on VxWorks in the management processor. -- Where am I, and what am I doing in this handbasket?
