Netonix Forums

Hi there,

I'm having issues with a LAG setup between a Cisco ASR920 and a Netonix. Just wondering if anyone has seen anything similar?

On the Netonix what I have configured: port 1&2 key 0, LACP-A, Slow, 32768. I've tried switching to LACP-P & static as well, no change.

On Cisco:

Code: Select all

 
interface Port-channel5
description ETHERCHANNEL TO TOWER NETONIX
 mtu 9000
 no ip address
 no negotiation auto
 no keepalive
[vlans here]
!
interface GigabitEthernet0/0/4
 description LINK TO NETONIX - PORT 1
 mtu 9000
 no ip address
 media-type auto-select
 negotiation auto
 channel-group 5 mode active
!
interface GigabitEthernet0/0/5
 description SECOND LINK TO NETONIX - PORT 2
 mtu 9000
 no ip address
 media-type auto-select
 negotiation auto
 channel-group 5 mode active


Logs on the Cisco switch:

No noteworthy logs on the Netonix, I don't see the flapping in the logs. Not sure what here really to check.

I was unaware that Cisco supported LACP LAGs in their routers, they do in their switches.

I use STATIC LAGs between my Cisco 2951 and my Netonix for that reason.

I know you can put in certain 4 port EHWIC expansion switch cards and then establish LACP on the switch card from the router but never tried it.

Yeah the ASR901/920 series supports LACP. They're really switch/router combos meant for outdoor telecom sites and hardened for harsh environments.

I'll try setting both for static and see if that makes a difference.
