Which switches are v1 and which switches are v2?

[Anonymous]

Hello,

I upgraded two 3500yl-24G to K.15.14.0003 and connected to pox with l2 topology and HP SDN 2.0 network controller. Than I tried to ping which worked but had a latency of 1.2 ms normally it would be 0.3 ms. Than I tried

to do netio between the nodes which gave me a throughput of 8 MByte/s but it should above 100 MB/s for Gbit ethernet. I also noticed that the CPU consumption of the switch went up to 80% + so verify my assumption that

the switch is operating in software, I run the following commands:

 After seeing that the flows are installed in software, we tried to enable ip control table mode, which failed:

HP-3500yl-24G(openflow)# ip-control-table-mode
IP Control Table Mode cannot be set when V1 module is enabled.

 We can see that the flows are installed in software:

So it appears that v1 hardware is completly useless for OpenFlow becaue it can't even switch layer2 in hardware.

Can someone provide me with a list of HP switches which support Layer 2 and Layer 3 in hardware?

Is there a list of devices which are v1 and which are v2?

Cheers,

The 3500 is a V1 switch. The 2920 and 3800 are V2 switches and the 5400 and 8200 support V2 modules. If you have only V2 modules in a switch, it is a good idea to disable v1 modules with "no allow-v1-modules". The 2920 does have one limitation that the 3800 and other V2 devices don't. It cannot process rules in hardware that are based on destination MAC address.

I also recommend that you look at the OpenFlow guide for the switches: http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/action.process/public/psi/manualsDisplay/?sp4ts.oid=3457354&javax.portlet.action=true&spf_p.tpst=psiContentDisplay&javax.portlet.begCacheTok=com.vignette.cachetoken&spf_p.prp_psiContentDisplay=wsrp-interactionState%3DdocId%253Demr_na-c03991489%257CdocLocale%253Den_US&javax.portlet.endCacheTok=com.vignette.cachetoken 

The 3500 is useful and can process rules based on L3 information in hardware.

Hello Eric,

the document you mentioned lists the 3500 being capable of matching all fields for IPv4 in hardware in figure 7 on page 70. Is this information wrong? It also lists SRC and DST MAC. This is for firmware KA.15.14 which I have installed.

Hi Thomas,

Wow, no the doc is not correct. I sincerely appologize. For v1 devices on K.15.14, the VLAN Priority, Src & Dst MAC fields should be yellow.

I will get the doc fixed.

Thank you for bringing it to my attention,

Eric

Hello Eric,

thank you so much for the clarification. Now everything is clear. Next week I hopefully get my hands on v2 hardware

and can continue my tests.

Cheers,
