[f-nsp] MLXe slow on 10G doing inter-vlan routing

[Tudor Capatina]

Hello,

You can have a nice read here:

https://puck.nether.net/pipermail/foundry-nsp/2006-December/005382.html

and just for reference the documentation for the commands:

http://www.brocade.com/content/html/en/configuration-guide/NI_05800a_SWITCHING/GUID-04EDFD31-E5FB-4593-8434-0DF8EDB3249E.html

Have a nice day!

 Hello,
 
 Could you please explain the correlation
 between this commands and performance issues observed by the
 OP ?
 
 Best regards.

 i second
 that,
 
 
 
 no ip icmp redirects - in global config mode or
 
 no ip redirect - in interface config mode
 
 
 
  and you are good to go.

  Turn off
 
  ICMP redirects. Common problem in one arm routing
 configs.
 
  IMO it should be the default setting but it's not.

  Do you notice the same behavior with both UDP and

  MLXe,
 
  very lightly loaded, with only one card
 BR-MLX-10Gx8-X. 
 
  Simplest of configuration, layer 2 link with VE
 
  interfaces.  During inter-vlan routing where the
 ingress
 
  traffic and egress traffic are on the same port, say
 e1/2,
 
  the input traffic level will be fine, but the output
 traffic
 
  is effectively maxed out at about 50Mbps (on a 10GigE
 
  port).  Shift hosts around so that the egress is a
 
  different port on the same card, bang problem gone and
 full
 
  expected traffic rates achieved.
 
 
 
 
 
 
 
  Tried numerous code versions, from 05800a to 05900a to
 
  06000.  No improvement.
 
 
 
 
 
 
 
  Of course tried rebooting, new optics, new cabling. 
 No
 
  errors incrementing on the interface.  This is the
 silliest
 
  dumb problem in a long time.  Any ideas are
 appreciated.
 
 
 
 
 
 
 
  Thanks!
