Configuring Dynamic (LACP) and Static LAGs on ICX Switches

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:

Could you help 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, 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 @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
