LeMarr, Two things. Guest LANs using Hipersockets don't support broadcast. Guest LANs using QDIO do support it. You have to be at z/VM 4.3 to be able to define a QDIO Guest LAN.

I have an hsi0 defined on both Linux Guests, but I think I have it pointing to the wrong broadcast address. Can I make up a broadcast address (10.22.25.1). or should I select the VMTCPIP Router eth0 (10.25.25.155) or to the Cisco Router (10.25.1.1). and do change the default of the guest to point to (10.22.25.1)? -----Original Message----- From: Dennis Musselwhite [mailto:[EMAIL PROTECTED]] Sent: Friday, January 31, 2003 3:26 PM To: [EMAIL PROTECTED] Subject: Re: z/VM Guest LAN using HiperSockets Hi, It looks like you are dedicating a LAN segment to each Linux guest. With Guest LAN you are no longer restricted to the point-to-point model. Define just one Guest LAN (VHIP1) for this segment and one virtual HiperSockets adapter for each guest (TCPIP, LINUX01, and LINUX02). Each guest connects (via the CP COUPLE command) to the same Guest LAN. You can eliminate DEVICE VHIP2 and LINK VHIP2 statements... The HOME list can include both IP addresses, but both should name the same link (VHIP1). You can drop the VHIP2 entry from the GATEWAY list. And... the START VHIP2 can be eliminated. To "wire" your virtual network, somebody has to "own" the LAN segment (ownership of the LAN makes it easier to manage it). For example, if you want TCPIP to own it, you have to issue (from the TCPIP userid): CP DEFINE LAN VHIP1 This is the simplest form to create a HiperSockets LAN segment. For each guest (TCPIP, LINUX01, and LINUX02) you need to define a NIC (instead of a CTCA) and couple to the LAN (instead of a specific peer). For example: CP DEFINE NIC 2000 CP COUPLE 2000 TO TCPIP VHIP1 After you DEFINE LAN and couple from all three guests, you should be able to confirm those connections with the command: CP QUERY LAN VHIP1 DETAILS Regards, Dennis Musselwhite ([EMAIL PROTECTED]) IBM Corporation -- z/VM Development -- CP Network Simulation "Ketchens, LeMarr T.

Right now, I need to know how to get this running with Guest LAN using virtual Hipersockets. I think I can figure the issues on the Linux Guest side, but I need to know what to use in the PROFILE TCPIP. I need to know based on the following: OSA-E 0090-0092 => z/VM TCPIP => 10.25.25.155 Virtual HIPER 2000-2002 => Portname:VIRTHIP1 Virtual HiperLan 2100-2102 => Portname:VIRTHIP2 Projected Linux Guest IP Addresses: Linux01 => 10.22.25.10 Linux02 => 10.22.25.11 We do have a Cisco Router => 10.25.1.1 ; OSA-E GIGABIT ETHERNET CARD ON Z/800 CHPID =>00 DEVICE DEV@0090 OSD 0090 PORTNAME VMHOST PRIROUTER LINK ETH0 QDIOETHERNET DEV@0090 ; VIRTUAL HIPERSOCKETS 2000-2002 VHIP1 DEVICE VHIP1 HIPERS 2000 PORTNAME VIRTHIP1 AUTORESTART LINK VHIP1 QDIOIP VHIP1 ; VIRTUAL HIPERSOCKETS 2100-2102 VHIP2 (Guest LAN) DEVICE VHIP2 HIPERS 2100 PORTNAME VIRTHIP2 AUTORESTART LINK VHIP2 QDIOIP VHIP2 HOME 10.25.25.155 ETH0 10.22.25.10 VHIP1 10.22.25.11 VHIP2 ; (End HOME Address information) ; ------------------------------------------------------------------ GATEWAY ; ------------------------------------------------------------------ 10 = ETH0 1500 0.255.0.0 0.25.0.0 10 = VHIP1 1500 0.255.255.0 0.22.25.0 10 = VHIP2 1500 0.255.255.0 0.22.25.0 DEFAULTNET 10.25.25.155 ETH0 1500 0 ; (End GATEWAY Static Routing information) START DEV@0090 START VHIP1 START VHIP2 ; (End START statements) With these as the statements, I want to know if I'm going down the wrong path trying to utilize Guest LAN with virtual Hipersockets. --- Legal Disclaimer: The information contained in this communication may be confidential, is intended only for the use of the recipient named above, and may be legally privileged.
