Sflow on Fesx448??

[metallica]

Hi,
Does FESX448 running PREM image support Sflow? I can configure FCX624 and Fcx648 without any issue. But the same settings does not work on the FESX448.

This is sh ver

metallica,

Are you saying this config is not working on fesx? OR is it the output from the fesx unit itself? Could you provide more info?

[metallica]

Well that's my switch config output. And this configuration do not work for sflow collector. Means collector are not able to get any data.

[dvenkat]

metallica,

By switch config output, do you mean this config is from FCX switch where its working OR is it from FESX  ?

[metallica]

Settings in FCX is working fine.

FESX is not working. You see output of fesx above.

Thanks

metallica,

Have you also enabled 'sflow forwarding' on the switch using the following steps at the interface level?

Enabling sFlow forwarding on individual interfaces:

To enable sFlow forwarding enter commands such as the following.

Brocade(config)#sflow enable

Brocade(config)#interface ethernet 1/1 to 1/8

Brocade(config-mif-1/1-1/8)#sflow forwarding

[metallica]

Ofcourse for e.g

interface ethernet 26

sflow forwarding

!

interface ethernet 27

port-name HV1P1

sflow forwarding

!

interface ethernet 28

port-name HV1P2

sflow forwarding

!

interface ethernet 29

port-name HV1P3

sflow forwarding

!

interface ethernet 30

port-name HV1P4

sflow forwarding

!

interface ethernet 31

sflow forwarding

!

interface ethernet 32

port-name "eth0 Node"

sflow forwarding

!

interface ethernet 33

port-name "eth1 Node"

sflow forwarding

!

interface ethernet 34

sflow forwarding

!

interface ethernet 35

sflow forwarding

!

interface ethernet 36

sflow forwarding

!

interface ethernet 37

port-name HV4P1

sflow forwarding

!

interface ethernet 38

port-name HV4P2

sflow forwarding

sflow enable

[dvenkat]

metallica,

Thankyou for sharing the above configuration. You are able to enable sflow forwarding, which means the sflow command is available and it should be supported. Can you share the output of the following two commands as well?

'show sflow'

'show statistics brief ethernet 26 to 38'

The 'show sflow' command basically displays all the sflow information and port statistics. The second command 'show statistics brief ethernet 26 to 38' gives the configuration details on each of these interfaces and would tell us if there is traffic coming into those ports.

Hi metallica,

          Quote "sflow destination x.x.x.x 6969    <------------ using custom port"

Can you try the FESX with the default port for sFlow (6343)?

If that cannot be done can you please do a PCAP - I am thinking the FESX might only send via 6343 (sFlow is an ASIC function), but I do not have access to a FESX to test for you.

Thanks

Michael.
