Alcatel Unleashed

Posted: **09 Jun 2008 12:31**

Anyone any experience with connecting a Cisco Catalyst 6509 to an Alcatel-Lucent 6850 based on a LACP connection?

When I try to do so I don't get a working link. On the Cisco the LACP seems to be okay. Trunk is coming up and in the statistics I see sending and receiving of LACP packets. On the 6850 however the Link is UP but the Operational state stays down.

-> show linkagg port

Slot/Port Aggregate SNMP Id Status Agg Oper Link Prim
---------+---------+-------+----------+----+----+----+----
1/1 Dynamic 1001 CONFIGURED NONE DOWN DOWN UNK
1/2 Dynamic 1001 CONFIGURED NONE DOWN UP UNK

These are the commands I used on both switches:
Catalyst 6509 with CatOs 8.1(3)
set channelprotocol lacp 4
set port lacp-channel 4/43-44 976
set trunk 4/43 nonegotiate dot1q 1-1005,1025-4094
set trunk 4/44 nonegotiate dot1q 1-1005,1025-4094
set port lacp-channel 4/43-44 mode active

Alcatel-Lucent 6850, 6.1.3.719.R01 GA
-> show configuration snapshot linkagg
! Link Aggregate :
lacp linkagg 1 size 2 admin state enable
lacp linkagg 1 actor admin key 886
lacp agg 1/1 actor admin key 886
lacp agg 1/2 actor admin key 886

When configuring a second 6850 with the same commands and interconnecting them the LACP link aggregation is up and running in no time. Any suggestions on what I'm doing wrong?

Rens

The "actor admin key" on AlcaLu side must match your channel-group ID [1]. (So change either the Cisco or AlcaLu config)

When I look in the Cisco

SW6509> (enable) show lacp-channel
Channel Id Ports
----------- -----------------------------------------------
875 4/21-22
876 4/23-24
881 4/34-35
886 4/43
SW6509> (enable)

It gives me a channel Id. This is the value I used on the ALU switch. I guess I should have used the value 976 in my case?
set port lacp-channel 4/43-44 976
Tommorrow morning when I'm in the office this is the first thing I'll try.

Correct, this is exactly what I understand from the Cisco document.

Good luck for tomorrow. Please let us know if this helped you. I have no Cisco devices around, so I can only say that your AlcaLu config is correct.

Looking forward for your reply.

Still no luck

, There is some improvement but no connection jet. The Operational State stays down. However the Number of Selected Ports and Number of Reserved Ports changes to 2.
There is also a change in the ports themselves. Port State changes to RESERVED and Selected Agg Number changes to the right value, 10.

Any suggestions?

Rens

No need to set the "partner key" on the AlcaLu switch. Did you follow the Cisco guide I posted? They have other configuration lines as you have.

Could you maybe post your whole Cisco configuration while removing security related stuff like company descriptions and password hashes?

Is the aggregate on Cisco side "no shut"?

Hello Benny,

I'm afraid the url you posted containd information about the IOS based Catalyst. Not the CatOs which is used on my system.

Hi Rens,

I am not an expert with Cisco - sorry for that.

According to the following guide the actor key has only local preference (this is not what I learned):
http://www.cisco.com/en/US/tech/tk389/t ... shtml#diff

Your configuration looks ok....

Here is an example I found for a connection between an Alcatel OmniSwitch 8800 and Cisco 4006

# Ensure that the admin keys are the same on both ends

# Ensure that the ports in the linkagg are set to the same speed/duplex

# In this situation, we needed to ensure the 8800 ports (on OS8-GNI-U8) were set to auto/auto

# OmniSwitch 8800
– assuming that ports 1/3 and 2/3 will be used with an admin key of "2" on linkagg number "2" with up to 4 ports being allowed to join
lacp linkagg 2 size 4 admin state enable
lacp linkagg 2 name "LACP 802.3ad to Cisco 4006"
lacp linkagg 2 actor admin key 2
lacp agg 1/3 actor admin key 2
lacp agg 1/3 partner admin key 2
lacp agg 2/3 actor admin key 2
lacp agg 2/3 partner admin key 2

# Cisco 4006
– assuming that ports 1 and 2 on module 1 will be used with an admin key of "2"
- ensure that ports are configured for the same VLANs/speed/duplex and trunking mode first
set cdp disable 1/1-2
set trunk 1/1 off !! only if not using 802.1Q
set trunk 1/2 off !! only if not using 802.1Q
set channelprotocol lacp 1
set port lacp-channel 1/1-2 2
set spantree portfast 1/1-2 disable
set port lacp-channel 1/1-2 mode active

I hope this helps you .. maybe not the LACP but the trunk + CDP is the root cause of the issue ...

Hello Benny,

I found the answer to my problem. It took some work and I even needed a extra switch to find the sollution.
But anyhow it's solved. Currious about what caused the problem?

The ports I used on the Catalyst where originaly used for something else. I changed them to a 802.1q trunk but that's not enough on the Catalyst.

Code: Select all

#module 4 : 48-port 10/100/1000BaseT Ethernet
set vlan 2    4/1-2,4/5,4/7-16,4/45
set vlan 3    4/3-4
set vlan 5    4/6,4/17-18,4/20,4/25-40,4/46-48
[b]set vlan 6    4/19,4/41-44[/b]
set port speed      4/30,4/37 1000
set port trap       4/1-48  enable
set cdp disable  4/43-44
set trunk 4/21 nonegotiate dot1q 1-1005,1025-4094
set trunk 4/22 nonegotiate dot1q 1-1005,1025-4094
set trunk 4/23 nonegotiate dot1q 1-1005,1025-4094
set trunk 4/24 nonegotiate dot1q 1-1005,1025-4094
[b]set trunk 4/43 nonegotiate dot1q 1-1005,1025-4094
set trunk 4/44 nonegotiate dot1q 1-1005,1025-4094[/b]
set trunk 4/45 nonegotiate dot1q 1-1005,1025-4094
set spantree portfast    4/43-44 disable
set port lacp-channel 4/21-24,4/43-44 mode active

The ports needed to be in vlan 1 to get the LACP trunk working. Don't ask me why but after changing this the trunk came in service instantaniously.

Anyhow thanks for your help,

Regards,

Rens
