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

I decided to take a stab at 6601421 dladm set-linkprop should support multiple -p options along with some related linkprop fixes, but when I looked into dladm.c, was surprised to find that "dladm_parse_props()" is called from do_create_aggr and do_create_vlan in addition to the expected (by me, at least) do_create_vnic *linkprop functions. What happened here? Why do we pass in

Crossbow team, The following is of interest to the Crossbow project. Since a large chunk of these changes also exist in the Crossbow gate, the delivery of this wad will result in fewer lines of changes for Crossbow''s delivery. If someone on Crossbow could participate in this review, that would be a bonus (Eric Cheng made original changes in the Crossbow gate at some point last year).

Hi, Pradeep: I believe you had some questions about modifying bandwidth for flows/VNICs. I believe that should be fine in the recently released bits, could you please check and lets know if you still have any questions about this. Bandwidth limits can be modified using: links: dladm set-linkprop -p maxbw=<value> linkname flows: flowadm set-flowprop -p maxbw=<value> flowname (I

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:

Hi, I''m trying to BFU my own build of ON onto a snv_104 installation and I''m hitting problems with bnx driver; which is coming from a set of snv_105 closed bins: WARNING: bnx0: Failed to allocate GLD MAC memory. I believe bnx is a closed source GLDv3 driver. Were there any incompatible changes due to the crossbow integration that went in after snv_105?

Following is a short description on assigning priorities to a link (via dladm). Flows will have a similar mechanism (via flowadm). thanks, -venu ---------------------------------------------------------------------------- The components associated with a link or flow, such as Soft Ring Sets, Soft Rings and squeues, have kernel threads processing inbound/outbound packets. The scheduler

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

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

I just BFU''ed up to B61 and started to play with IP Instances. I''m having trouble making my zone happy: root at aeon zones$ zoneadm -z testing1 boot zoneadm: zone ''testing1'': WARNING: unable to hold network interface ''skge0''.: Invalid argument root at aeon zones$ dladm show-dev nge0 link: up speed: 100Mb duplex: full

hi all, got question about using wifi (wpi) with xen. from doc i understand that the nic in dom0 must be based on GLDv3.

Hi All, I have bfu''ed to net-virt_xb-21_snv_81_021308. The dladm command on my machine does not have create-etherstub option. Please let me know what could be the issue. Thanks Khushal

So, just to play with vnics with 106, I have... e1000g2 plumb''d with 192.168.85.10 vnic0 is created on top of e1000g2 with 192.168.85.22 I snoop on e1000g2 to see the traffic. I ping 192.168.85.22 and it works. I stop the snoop on e1000g2. I ping 192.168.85.22 and it doesn''t work. I start the snoop on e1000g2. I ping 192.168.85.22 and ping works. Is this a new feature with

Hi the Crossbow team, I am testing my UV fastpath bits and I found several issues that need your suggestion: 1. dladm show-usage won''t work if UV fastpath is enabled. Since the link usage data are collected based on the statistics of the mac_client_impl_t, and UV fastpath skips the GLDv3 processing, that won''t be available. I don''t see a solution for this except

Hi all, Link protection is a new feature we are planning to introduce to Solaris and we would like to solicit your feedback on it. Please see attached document for details.

got a problem with b75 that the zone with ip-exclusive just takes the identity of the global zone. For the primary nic there is no option to set its ip and hostname. When i change the host name and ip the hostname does not change and the networking goes weird for both the zone and global zone. sparc eri qfe There any bugs about or should this work fine?

It was rumored that Nevada build 105 would have ZFS encrypted file systems integrated into the main source. In reviewing the Change logs (URL''s below) I did not see anything mentioned that this had come to pass. Its going to be another week before I have a chance to play with b105. Does anyone know specifically if b105 has ZFS encryption? Thanks, Jerry -------- Original Message
