SLX9640 LAG Config

ben645 — Tue, 25 Jun 2019 00:06:43 GMT

Hi,

I am currently trying to setup a LAG on our SLX9640's but struggling a little. My config for my brocade is below:

lag "Netflix" dynamic id 1
ports ethernet 2/4
primary-port 2/4
lacp-timeout short
deploy
port-name "NetFlix PI" ethernet 2/4

I then have the configuration including IP address etc on the physical interface ethernet 2/4

I am trying to figure out how to this currently and believe i now need to use port-channel with Extreme. I am slightly confused as to how to create the above with extreme.

Thank you in advance.
Ben

Ben,

You are correct, with the SLX product we use the "Port-Channel" method of configuring LACP. This is similar to the VDX product if you are familiar with that.

First you will want to create a port channel interface:

code:

1. Enter the configure terminal command to access global configuration mode. device# configure terminal

2. Enter the "interface port-channel" command to create a new port channel interface at the global configuration level. 

device(config)# interface port-channel 30 

NOTE The port-channel interface ranges from 1 to 512. The example creates a new port channel interface of 30.

Then you can add member ports to the "channel-group":

code:

3. Configure the interface ethernet command to enable the interface. 

device(conf-Port-channel-30)# interface ethernet 1/5 
device(conf-if-eth-1/5)#

4. Add a port to the port channel interface as static. 

device(conf-if-eth-1/5)# channel-group 30 mode on

5. Or add a port to the port channel interface as a dynamic (using LACP), active or passive mode. 

device(conf-if-eth-1/5)# channel-group 30 mode active 
device(conf-if-eth-1/5)# channel-group 30 mode passive

I hope this helps. For more information please read up on the L2Guide for our SLX products:

Hi Mike,

thank you for this! How do I assign an IP address to the port channel? In brocade you just put the IP details on the physical interface but I get the error trying this on extreme as it’s part of a port channel.

thank you again.

For SLX, you would want to do this via a VE:

Create Vlan 100 interface

code:

#vlan 100

Add "router-interface Ve" for vlan 100

code:

#vlan 100
 router-interface Ve 100

Add "ip address 1.1.1.1/24" for Ve 100 interface

code:

#interface Ve 100
 ip address 1.1.1.1/24
no shutdown

Create port channel interface 100

code:

#interface Port-channel 100

Add vlan 100 to port channel 100

code:

#interface port-channel 100
  switchport
  switchport mode trunk
  switchport trunk allowed vlan add 100
  switchport trunk tag native-vlan
  shutdown

Assign port channel 100 to the desired physical interface

code:

#interface ethernet 0/9
  channel-group 100 mode active type standard
  lacp timeout long
  no shutdown
