3550 - 12T Speed Issue

edw · ‎09-30-2011

Hi,

I have a Cisco 3550-12T and I have a few different machines plugged in for 1 gigabit connections. I seem to have a limit of 40MB/s to 45MB/s across machines. However the machines will run faster. For instance I plugged it into a dum Belkin 1Gigabit switch and got 65MB/s.

What could be causing this on the switch ?

Thanks

Ed

Hi Ed, can you post the following when connected to both?

sho run int xxx

sho interf xxx

sho interf xxx switchport

One thought is the port being set to desireable and changing between an access port and trunk port..., but would like to see the flow control.

Thanks,

Tim

Hi,

show run int xxx

switchport access vlan 30

switchport trunk encapsulation dot1q

switchport trunk allowed vlan 31,32

switchport mode access

spanning-tree portfast

This looks a bit odd to me ??

Another port -

switchport access vlan 30

switchport trunk encapsulation dot1q

switchport trunk native vlan 31

switchport mode access

spanning-tree portfast

One more -

switchport access vlan 30

switchport mode access

spanning-tree portfast

Hi,

Just to clarify more. I have done some more checks and the data is going from port 4 to port 9 and using 30% of each port. Nothing is going out of the switch to the rest of the network ???? I have tried different NICs, hard drivers, servers, PC's etc - but still getting this annoying limit ??

Thanks

Ed

You might be bumping against the performance capabilities of that switch. It's documented as having 17 Mpps and a 24 Gbps fabric.

Hi,

I would be gobsmacked if I'm hitting the max capcity. I only have two machines doing a copy. I would like to think I bought a gigabit switch not a 200Mbps

Thanks for any help

Oops, sorry. Numbers I posted last night are correct, but I slipped a decimal place calculating performance. You should NOT be hitting the performance limitation of this switch. For guaranteed wirespeed for 12 gig ports, you need a fabric of 24 Gbps, which it has, and 12 * 1.488 Mpps = 17.856, so its 17 Mpps is unlikely to be much of a performance limitation.

PS:

Not all switches, especially older models, guarantee wirespeed, but this particular switch should.

Hi Ed,

Can you post the following outputs from two 'sample' ports where you see the limits in data transfer (ex port 4 and 9)

Had a issue with show tcam as this command has loads of sub commands ??

Thanks for any help on this.

Hi,

Anyone any ideas - what speeds are people seeing on these units when copying ?

Thanks

Hey,

So the main symptom we see is that 3750 giving 40 MB copy speed while other dummy switch (possibly hub) gives up to 60 MB. So far I don't see any drops on 3750 - it would definitely drop if were not able to pass through all it get on wire and we would see counters growing.

Can you please get these commands from ports in a copy path:

show queueing gi1/x
show int gi1/x switching (this is hidden command so type exactyl this way)

Nik

HTH,

Hi,

Yes thats correct - thou its a 3550 not a 3750 ?.... The other is a bum switch/hub not sure which.

Sorry my typo. Can you please also get these outputs:

show controller ethernet-controller port-asic statistics

show buffer

for further valid test we would need smth like IPERF SW installed on servers/PC to test the speed rates.

There is a lot of data for the asic - thou the above commnd doesnt exist.

We tried a tool for measuring bandwidth and speed but same results

Thanks
