Migrating from L3 Cisco Switch to L3 Aruba Switch

Hello, good afternoon,

I am trying to migrate a client's core switch from Cisco to Aruba, they have a Cisco 3560-24X TL and I need to offer an Aruba switch with the same performance and throughput, I would like to have some help in this and if I can do this configurations in Aruba, it is exclusive and I prefer to ask here than saying yes without knowing the answer.

mls qos queue-set output 2 buffers 16 6 17 61
mls qos

 

And inside the GigabitEthernet interfaces they have this configurations:

interface GigabitEthernet0/23
description Enlace PPal 314900
load-interval 30
srr-queue bandwidth share 10 10 60 20
queue-set 2
priority-queue out
mls qos trust cos
channel-protocol lacp
channel-group 2 mode active

 

Can I do it in Aruba? 

Thanks.

Re: Migrating from L3 Cisco Switch to L3 Aruba Switch

Hi! I just chime in for the part related to interface aggregation; on the example you provided the Interface 0/23 is a member of the logical EtherChannel 2:

channel-protocol lacp
channel-group 2 mode active

so you should expect two things: the first is that somewhere in the configuration the channel group with id 2 (it uses LACP as Aggegation Control Protocol) is defined and the second thing is that a second physical interface is made member of that same channel group with id 2.

The other part is about COS mappings and I haven't enough experience to help.

Hello Parnassus, thanks for your interest.

Yes, the switch has the channel group with ID 2 defined:

!
interface Port-channel2
load-interval 30
!

And there are two interfaces in the EtherChannel:

!
interface GigabitEthernet0/24
description Enlace Resp 314903
load-interval 30
srr-queue bandwidth share 10 10 60 20
queue-set 2
priority-queue out
mls qos trust cos
channel-protocol lacp
channel-group 2 mode active
!

I know I can make LACP in Aruba, my problems right now are the QoS configurations, because it is a contactability provider.

 

Regards.

Re: Migrating from L3 Cisco Switch to L3 Aruba Switch

Update: I found this PDF https://hpepress.hpe.com/product/ArubaOS-Switch+Comware+and+Cisco+IOS+CLI+Reference+Guide-PDF-18113

It helped me to do some QoS mapping configurations, now I'm just lacking the input and output buffers and thresholds.

I hope that it helps to everyone having alike problems.

Regards.

Re: Migrating from L3 Cisco Switch to L3 Aruba Switch

Yeah...we were aware of it already...indeed it would have been my next suggestion to you (but you were faster than me) as that guide is sort of Rosetta Stone to consult before anything else in Cisco IOS versus ArubaOS-Switch cases.
