What release of VM on you on? In 5.3.0, we separated the default VLAN and the native VLAN. Prior to 5.3.0, the default VLAN is the same as the native VLAN. In this case, defining the VSWITCH to default to VLAN 147 means that 147 is the native VLAN (or untagged set). Most likely, the OSA card is plugged into an access port on the physical switch and traffic coming into the VSWITCH for 147 is not tagged. Once you change the default on the VSWITCH that untagged traffic is associated with the new default (which does not equal 147) and is then not delivered to the guest (granted VLAN 147). A conversation with your networking folks is probably in order. In most situations, we recommend that if you want to use VLANs on your VSWITCH plug your OSA card into a trunk port on the physical switch. Then define your VSWITCH to default to the native VLAN id of the physical switch.

Our network folks have configured their 6509 connection to our OSAs with 1 VLAN - 147. If I define my VSWITCH with a default VLAN ID of 147 and then "grant IPSTACK VLAN 147" - all is OK - I can PING etc. However if I define the VSWITCH with a different VLAN ID I cannot PING etc. I assume that the switch will tag any packets coming from IPSTACK with VLAN 147 so I should always be able to PING etc even if the default VLAN is not 147. What's the problem here? Me? Thanks. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
