S2500 Flow Control on 10GbE ports

Is it possible to enable flow control on the 10GbE ports of an S2500?  I've created an enet-link-profile setting flowcontrol to on and assigned to port, however, the show interface command shows that flow control is still disabled.  Assigning the same profile to a 1 gig port seems to work fine.

Can you dump o/p  for

 "show interface-profile enet-link-profile  <your-profile-name>"

"show running-config interface gigabitethernet <uplink-intf>"

 "show running-config interface gigabitethernet <uplink-intf> | include flowcontrol

  ex: show running-config interface gigabitethernet 0/1/2 | include flowcontrol

The following also indicates flow control is off, correct?

 

#show interface gigabitethernet "0/1/1"

Re: S2500 Flow Control on 10GbE ports

Boomboom21,

I suspect in your system log you have the following error:

 

Apr 6 14:42:26 :335311:  <WARN> |ChassisManager|  Configuration parameters under enet profile (EqualLogic-Enet-Profile) does not match for interface GE0/1/1, Ignoring the configuration

 

Try the following enet-link-profile instead:

 

!

interface-profile enet-link-profile "10GE-FLOW"
   speed 10000
   duplex full
   flowcontrol on
!

 

The reason is that the system is trying to apply "speed auto" and "duplex auto" when a 10G interface can only be speed 10000 and duplex full. If you apply the above profile instead, you should get the following:

 

(ArubaS2500-48P-US) (config) #show interface gigabitethernet 0/1/0

GE0/1/0 is administratively Up, Link is Up, Line protocol is Up
Hardware is Gigabit Ethernet, Interface is GE0/1/0, Address is 00:1a:1e:0a:23:f2
Encapsulation ARPA, Loopback not set
Configured: duplex (Full), Speed (10 Gbps), FC (On), Autoneg (On)
Negotiated: duplex (Full), Speed (10 Gbps)

 

Best regards,

 

Madani
