Having problem creating the LACP port

Hi All,

 

I have problem creating the LACP interface in Aruba switch, below is my configuration:

 

(GALLERY-SC-L1R-S01) (config) #interface-profile lacp-profile LACP_23
(GALLERY-SC-L1R-S01) (LACP "LACP_23") #Group-id 23
(GALLERY-SC-L1R-S01) (LACP "LACP_23") #mode active
(GALLERY-SC-L1R-S01) (LACP "LACP_23") #exit
(GALLERY-SC-L1R-S01) (config) #interface gigabitethernet 4/1/0
(GALLERY-SC-L1R-S01) (gigabitethernet "4/1/0") #lacp-profile LACP_23
Error: Interface is configured with non-default switching profile

 

(GALLERY-SC-L1R-S01) (gigabitethernet "4/1/0") #exit
(GALLERY-SC-L1R-S01) (config) #interface gigabitethernet 4/1/1
(GALLERY-SC-L1R-S01) (gigabitethernet "4/1/1") #lacp-profile LACP_23
Error: Interface is configured with non-default switching profile

 

This is a stacked Aruba switches (AOS ver 7.3.1.0) with four 48-port S3500 switches and one 24-port S3500 switch, the port 4/1/0 and 4/1/1 are the uplink ports which is on the 24P switch (Linecard of the stacking).

 

Please advise what's going wrong with this LACP configuration? Thanks in advance!

Re: Having problem creating the LACP port

I guess I have figured out the reason why it's not working, please see below configs I did on the GE4/1/0 and GE4/1/1.

 

Interface-profile switching-profile TRUNK
Switchport-mode trunk
Trunk allowed vlan all
Exit

Interface-profile lacp-profile LACP_23
Group-id 23
Mode active
exit

 

Interface-group gigabitethernet Uplink
Apply-to 4/1/0,4/1/1
Switching-profile TRUNK
Lacp-profile LACP_23
Exit

 

I firstly configured the 4/1/0 and 4/1/1 as the trunk port which is a MUST to change the default switching-profile to the TRUNK (named by myself) swithcing-profile, and this causes the LACP profile not able to be applied on these two ports.

 

I tried the exactly same configuration on another switch WITHOUT inroducing the trunk port, and the LACP is working fine.

 

The problem now is that, for my Arista MLAG setup, I must have both TRUNK + LACP configuration on these two uplink ports, and it looks like it's not possible to be done on the aruba switch, please advise any solution for this?

Re: Having problem creating the LACP port

I am familiar in Cisco equipment and have achieved my CCIE for years.

 

However, I am a newbie to Aruba stuff which I only started to deal with from last month.

 

In Cisco, just two simple setps to achieve what I want in this scenario:

 

Interface range gi4/1/0 - 4/1/1

channel-group 23 mode active

 

interface port-channel 23

switchport mode trunk

 

That's all, a LACP port-channel with Trunk is now configured on the Cisco switch. 

 

Please kindly show me what's the equivlent commands on the Aruba S3500 switches, thanks all!

If you are tagging multiple VLANs then you need the trunk interface
configuration.

Re: Having problem creating the LACP port

Parry,

LACP members cannot be part of an interface group. Once an interface is a member of LAG, it no longer inherits any config from interface-group it’s part of so you shouldn't configure them using groups. This is how they should be configured:

 

!
interface-profile lldp-profile "LLDP-CDP-ENABLE"
   lldp transmit
   lldp receive
   med enable
   proprietary-neighbor-discovery

!

interface-profile switching-profile "WIRED-VLAN-10"
   access-vlan 10

!
interface-profile lacp-profile "PORT-CHANNEL-0"
   group-id 0
   mode active
   timeout short

!
interface gigabitethernet "0/0/12"
   lldp-profile "LLDP-CDP-ENABLE"
   lacp-profile "PORT-CHANNEL-0"
!
interface gigabitethernet "0/0/13"
   lldp-profile "LLDP-CDP-ENABLE"
   lacp-profile "PORT-CHANNEL-0"
!
interface port-channel "0"
   switching-profile "WIRED-VLAN-10"

!

 

But in your case, the switching profile of port-channel 0 would be a Trunk.

 

Best regards,

Re: Having problem creating the LACP port

Sorry for reviving an old thread, but could you please clarify : Do I need to create a new port channel for each IAP? 

 

Thanks

Re: Having problem creating the LACP port

Yes, you do. Port-channels/trunks/LAGs can only be between two devices. Each IAP needs a port-channel/trunk/LAG.
