SFE2010 ingress rate-limit problem

[marcin]

Hi!

I have a simple question regarding SFE2010 48 ports switch: is there a possibility to rate limin on egress traffic on interface? Ingress works fine:

interface ethernet e4

traffic-shape 2048

rate-limit 1024

When I use traffic shape (with any variable) I have 0,61Mb on egress.

Am I able to setup for exampleL 1Mb/1Mb, 2Mb/512kb on interfaces (vlans) on this model? If no which Cisco model (from SMB "shelf") can do it for me?

Best regards,

Martin

Dear Martin,

What you are looking for is located on the Bandwidth Page (Quality of Service > General > Bandwidth) where you can set Ingress Rate Limit and Egress Shaping Rates .

For detailed information on how to configure this please see Page 289 of the SFE-SGE2xxx Admin Guide PDF available here:

http://www.cisco.com/en/US/docs/switches/lan/csbms/sfe2000/administration/guide/SFE-SGE2xxx_Admin_Guide.pdf

Thanks and regards,

O! thanks Zsolt!

I have read manual and tried a lot of possibilites before I wrote.

Cisco rate limit is not working.

I have also new soft, etc......

Your move

Hi Marcin,

First I will confer with my colleagues from the engineering and development team regarding the issue and will let you know.

Second - regarding your other question - an alternative would be any of the new Cisco Small Business 200 or 300 series switches which have newly designed hardware and software. More info here:

http://www.cisco.com/cisco/web/solutions/small_business/products/routers_switches/index.html-tab-Switches

I'll keep you posted.

Thanks and regards,

Zsolt

Hi Zsolt!

Any news how to solve it?

Hi Marcin,

I must admit i use a great client / server utility called IPERF to check throughput.

I did set interface rate limiting, which ingress rate limits.  I had a PC client  connected onto a router via switch port 24 of my SGE2000P and a IPERF server (XP old laptop) on SGE2000P ethernet port G1. Sorry I don;t have the same hardware as you, but a member of the same family.

I set varied   values to rate limit on port 1 and port 24 and  ran the test a number of times, got the following results in blue below;

I would suggest if you are having trouble you should  have a word to the good folk at Small Business Support center.

Hi David!

thank you for your response and your time, which you get round to configure lab. ipref is a nice tool but it is not easy to go to 40 customers, and explain that speedtest.net doesnt't work I suppose, Ipref works probably because of TCP window size. Also, when i use several portals to check speed there is no problem to point precisely download speed (all test shows right speed).

When I test HP/3com 4500 switch it works (line-rate inbound 1024,  line-rate outbound 1024: thats all!).

:/

best regards

Marcin
