objects disappear from dladm after reboot
On OpenSolaris 2009.06 I created a flow, half a dozen VNICs, and I set some properties, and everything was working, then I rebooted my system and everything disappeared from show-vnic, show-flow, and show-prop. When I tried to re-create the objects, dladm said they already existed. While I could not see the objects, I could delete them. Example: # dladm show-vnic # dladm create-vnic -l bge0

Can''t create a virtual nic
Howdy, I just installed the crossbow snapshot from opensolaris.org, and bumped into an issue when attempting to create a virtual nic: $ dladm create-vnic -i 192.168.1.101 -d ni0 2 dladm: VNIC creation failed: No such file or directory (unknown diagnostic) When I truss the process, it looks like it''s failing when attempting to open the vnic pseudo-device: 100878/1:

dlstat for data link statistics
(Bcc''ed to networking discuss). Hi All, Have enclosed man page draft for dlstat(1M) herewith. This is part of the effort to gain better visibility into network traffic in light of crossbow features like virtual NICs, interrupt vs. polling modes etc. This in turn would greatly assist network performance analysis. It is also aimed at segregating link/flow configuration from

trouble with maxbw
Folks, I''m playing with maxbw on links (as opposed to flows) in Crossbow, and I have a couple of questions. First, the limts seem only advisory. The first example has the main host talking to a zone that has 172.16.17.100 configured on znic0. When there is no maxbw, the throughtput is as expected; when maxbw is 55M the throughput only drops to 76 Mbps: # netperf -H

Crossbow and zones
Howdy, I just finished reading through the Crossbow presentation: http://blogs.sun.com/sunay/resource/crossbow.pdf And have one question. If you create a virtual NIC with dladm: $ dladm create-vnic -d bge0 -m 0:1:2:3:4:5 -b 10000 1 Can you then add vnic1 directly to the zone? e.g.: zonecfg -z zone1 zonecfg:zone1> create zonecfg:zone1> set zonepath=/zones/zone1 zonecfg:zone1> add net

Duplicate packets when using aggregate datalinks on bge
I opened a bug report earlier today but it doesn''t seem to have been added to the bugs database. I''m posting here in case one of the Crossbow developers might see it and confirm this behavior. Description Duplicate packets are generated whenever an aggregate is introduced into the network configuration. We''ve ruled out switch ports and physical bge interfaces as

Issue with Crossbow on VirtualBox
Team, We are trying to install Crossbow on VirtualBox. Siva first tried it on Linux and reported it in Hyderabad Open Solaris User Group alias. http://opensolaris.org/os/project/hosug/ Today both of us tried it on VirtualBox running on OpenSolaris. Both attempts have the same results. a. Selecting Solaris Developer Express during boot process exits the installation. See this picture:

questions from a 10GbE driver author
Hi, I maintain a driver for a 10GbE nic which supports multiple hardware tx/rx rings. We can steer rx packets into rings using the "standard" NDIS6 Toeplitz hashing on TCP port numbers, IP addresses, etc. We can also steer packets based on MAC address. Would this NIC be considered to be capable of supporting crossbow? Also, can crossbow do things like steer outgoing packets to the

Reclaiming transmit descriptors by NIC drivers with Crossbow new scheduling
The following is mainly a capture of parts of multiple off-line discussions within members of the Crossbow team (Gopi, Thiru, Roamer, May-Lin, Thirumailai, Nitin, KB, ...), I thought I''d open it up to other participants. Crossbow''s core scheduling involves switching a NIC (or individual Rx rings on the NIC) to polling mode. The receive interrupt will become not only rarer,

Crossbow integration with Solaris 10/08
Hi, >From what I have read, the create-vnic feature in dladm is only available within the context of crossbow...? Specifically, what I am wondering is whether it is at all possible to successfully install crossbow on top of Sun''s "Standard/sunsolve supported" Solaris 10/08 rather than OpenSolaris, per. Se.... Is this at all feasible? Many thanks in advance.. Best

RFE wish list
Actually, it is not a list.. but just something that''ll be very useful to me in my business. If crossbow/virtual interfaces can provide a flow that can capture bandwidth usage over a period of time (including 95 percentile), that''ll be great! Is this possible? -- This message posted from opensolaris.org

Using tun interface with dladm and flowadm
Hello, I am a rather new user to OpenSolaris and I have been loving every minute of it. I have spent quite a lot of time looking around for bandwidth management features and Project Crossbow is just amazing. It is truly amazing compared to what Linux has to offer. I would like to use flowadm to do some bandwidth management on a tun interface. The problem is that it is not recognized by the dladm

creating a vnic to represent the factory MAC address
How do I create a vnic that represents the factory assigned MAC address of my physical nic? The bge device in my system (x2100) appears to support 4 MAC addresses. The driver reserves the first as the ''primary/default'' address and allows manipulation of the other three via the MAC_CAPAB_MULTIADDRESS interface. I''d like to use vnics on this system, as I have Xen guest

sppp device not routing ? (need help)
Ok, I''m hoping this is a fairly trivial issue, and I''m missing something. I''m trying to use Solaris zones (Nevada Build 117) to act as a DMZ and a router, using exclusive IPs, VNICs (from Crossbow), and connecting to the internet (static IP from my ISP). I''ve got the DMZ working - that zone sees the internet, can do name lookups, ftp, telnet, ssh, etc etc etc.

Controlling outbound bandwidth utilization by port
Among other things, I run an http server on my home DSL line (6M/768kbit). The content includes several large image galleries, and when certain crawlers hit our server w/ multiple large image uploads, we end up with large ping time delays - sufficient to disrupt the kids'' on-line gaming. Attempts to control this with robots.txt has not be very successful; Solaris IPQoS appears quite
