Configuring Dynamic (LACP) and Static LAGs on ICX Switches

BenBeck — Thu, 01 Feb 2024 20:29:04 GMT

Hey all,

Let's take look at creating LAGs (LACP and static). LACP (802.3ad) is the most common link-aggregation method. We also offer static LAGs.

To create an LACP LAG named 'testlag' with an auto-generated id, you would issue the following:

ICX#conf t
ICX(config)#lag testlag dynamic id auto

In this example, let's assign ports 1/3/1 and 1/3/3 to this LAG:

ICX(config-lag-testlag)#ports eth 1/3/1 e 1/3/3
LAG testlag deployed successfully!

The resulting configuration from 'show run':

lag lagname dynamic id 1
 ports ethe 1/3/1 ethe 1/3/3
!
<output omitted>
!
interface lag 1

We can see the LAG was assigned id 1 and there is also an 'intferace lag 1' in the running configuration. We can use this to define various configurations at the interface level. We will not define anything in our example, but I will show the the interface configuration mode for a lag for the sake of completeness.

ICX(config)#interface lag 1
ICX(config-lag-if-lg1)#

To ensure our LAG is working properly, you can issue 'show lag':

The most important part of this output is the [Ope] column on the far right. A LAG that is up and working will show ‘Ope’ for all ports in this column. If you see ‘Ina’ (inactive) here, you may want to confirm VLAN tagging, Layer 1 port statuses and the partner side LAG configuration.

Configurating a static LAG will be very similar. Using the same ports from our last example, the configuration would like this:

ICX(config)#lag teststaticlag static id auto
ICX(config-lag-teststaticlag)#ports eth 1/3/1 e 1/3/3
LAG teststaticlag deployed successfully!

Resulting configuration in ‘show run’:

lag teststaticlag static id 1
 ports ethe 1/3/1 ethe 1/3/3
!
<output omitted>
!
interface lag 1

The ‘show lag’ for a static LAG will look like this:

Hopefully the above two examples will give you confidence to deploy both dynamic (LACP) and static LAGs. We do have some additional LAG options. To see all available configuration options for LAGs, please see our FastIron Layer 2 Switching Configuration Guide:

What is the ‘Tag’ the only difference I see in mine and yours is that field. My LAG is not working properly. How can I rectify this? I’m working on a 7150 CP12

Hi,

I have examinated the LACP messages with Wireshark and I found that the source MAC address of the LACP messages is 0000.0000.0000 . This can cause problems on systems that drop such packets (because all-zeros is interpreted as illegal MAC address). In this case, what is the solution?

Hi there,

You may want to share the ICX switch model number and firmware version as well so that we can get this checked internally.

@BenBeck just a heads-up on this one.

Hey @holloo

That doesn't sound right. What code are you on? We have ways to look at this from the CLI. Please feel free to open a case (see my signature) if you would like us to take a look with you.

Hi,

The model number is ICX7150 (on the one side two ICX7150-C12P-2X1G stacked, and on the other side two ICX7150-24-4X1G also stacked). Firmware version is SPS08095d on the one side, and SPR08090d on the other side. Between two sides there are 2x1 Gbps transparent E-line services used by the ICX7150s in LAG. The E-line services are implemented with Huawei devices in which packets with illegal source MAC address are dropped. Both sides sent LACP messages towards Huawei devices with all-zeros source MAC address. Upgrading to SPS09010d solved the issue.

Hi, I have deployed a lag on my ICX 7450 switch with an Aruba 8320 switch configured with active lacp. However, the Aruba is showing port blocking. There is no lacp mode command on my ruckus to change the mode. Firmware is SPR08090D.

Hi @isaac_madriz @hashim_bharooc1,

Could you help on this one.

Re: Configuring Dynamic (LACP) and Static LAGs on ICX Switches

Hi @Dinny

Please make sure you are configuring a Dynamic lag on ICX side following the steps suggested at the beginning of this post, that will be the LACP way to configure it from our side and off course make sure the physical connections you have on both ends are also matching what we are assigning in the dynamic configuration.

if that is correct, please share the configuration of the lag and a 'show lag' output to check the current status, in case you have lldp enabled you can also share the 'show lldp neighbors' to check the physical connections.

Thanks,

Hi @Dinny

Here is a sample lag vonfiguration

lag test1 dynamic id 10
ports ethe 1/1/1 to 1/1/2
port-name To-Core1-1 ethernet 1/1/1
port-name To-Core1-2 ethernet 1/1/2

deploy

Hope this helps.

Thanks
