Pinned topic IBM EN4093 --> LACP (Etherchannel) --> Cisco 4506 chassis
Wondering if someone can point me in the right direction. I am not a network person and am trying to work with a Cisco resource to get LACP working between a Flex Chassis (2 x EN4093) to a Cisco Catalyst 4506.
The Cisco resource has setup Ports on the 4506 chassis for Ether channel, Trunking Enabled and Tagging Enabled for VLAN's 1, 200, 300 (VLAN 1 Default..)
On the EN4093's I have done the following
1. Enabled VLAN Tagging on the EXT 7,8,9,10 (They are connected and active)
2. Enabled VLAN tagging on the INT ports that will be passing Tagged traffic.
2. Enabled LACP (Active) on the EXT 7,8,9,10.
From what I have read in the manual, with the EN4093 you do not configure both LACP and trunking like you do on the Cisco side.....So only LACP is active with VLAN tagging for 1, 200, 300.
So What I see is as follows.
1. "Non Tagged" traffic from the EN4093 working OK
2. Any "Tagged" traffic from the EN4093 is not working.
Not sure if this is enough info for assistance, as I said I am not a network resource (just trying to sort this out) so I may have missed something simple.
I'll see if I can provide more info during the week.
Any info, even the simplest of idea's would be appreciated. We have just started working on this, so hoping I can cut straight to the correct configuration quickly.

Did they set channel-group ACTIVE on cisco?
Can you please run command :
show lacp info?
- if you are not using "iscli " command line please enable it so your cisco guys will be able to help you with configuration:
login via cli,
then exit ,login again and choose iscli

Yes the channel groups is active, and when we check the Etherchannel it is "Up".
The LACP ports on the EN4093 switches are set to Passive mode, and the connections look to be OK when we query the Ether-channel on the Cisco Side.
We are just not sure if or how to configure the IBM switches for the VLAN's, obviously creating and assigning the VLAN's is not a problem...but there is something we are missing..

Can you please share output from :
isCLI: show int info

- RESOLVED --
Main issue is that the VLAN properties in the GUI are used to assign "VLAN's to Ports" when actually with respect to setting up trunking you need to "add ports to the VLAN's" via the CLI.
So to get this working we dropped using LACP and went to straight trunking....
The following steps were performed, NOTE: use your own specific port numbers..
The following is presented in a way consistent with their switch documentation. The menu is hierarchical, use ‘/’ to return to the top, and ‘..’ to return to the menu above.
/cfg/port EXT7/en represents going to the cfg menu, then port EXT7 menu, then running the en command. That is, entering ‘cfg’ followed by RETURN, then ‘port EXT7’ followed by return, and then entering ‘en’ followed by return.
1. Enable VLAN tagging on internal and external ports.
a. /cfg/port INTA1/tag ena
b. Repeat for each internal and external port
2. Create the applicable VLANs and optionally define tagged VLAN membership
a. /cfg/l2/vlan 200/name VLAN0200
b. /cfg/l2/def INTA1-INTA4 EXT7-EXT10
3. Define the port VLAN ID (untagged VLAN) on each port (default is 1)
a. /cfg/port INTA1/pvid 100 (sets PVID/untagged VLAN to 100)
b. NOTE: VMware vSwitch port group for this VLAN will need to be set as Untagged (0).
4. Static ‘trunking’ – NOTE: trunking is defined by IBM as being link aggregation, not VLAN tagging as per Cisco’s definition
a. /cfg/l2/trunk 1
b. /cfg/l2/trunk 1/add EXT7
c. /cfg/l2/trunk 1/add EXT8
d. /cfg/l2/trunk 1/add EXT9
e. /cfg/l2/trunk 1/add EXT10
f. /cfg/l2/trunk 1/en
Once configuration changes are made, run ‘apply’ for them to take effect and ‘save’ to save to Flash.
Restoring Factory Defaults
1. Apply and save any unapplied and unsaved configuration changes
2. /boot/conf factory
5. Reset (from the /boot menu)
Cisco side then needs to be set up for static EtherChannel with the correct untagged VLAN (native VLAN in Cisco parlance) and tagged VLANs assigned (via allowed VLAN list, if used). On some switch platforms, dot1q needs to be specified as trunk encapsulation.
Thanks to Josh for working this out...

we are current experiencing a similar problem. Our Cisco WS-4506 shuts the ports of our FlexSystem down (secure down) as soon as the ports are activated on the EN4093. Our IOS version is "cat4000-i9s-mz.122-24.EWA13", our EN4093 has firmware 7.7.5 installed. Did you by chance experience a similar problem?

hola, espero alguien pueda ayudarme, tengo un switch modelo EN4093R, tengo muchasa dudas sobre como instalare las maquinas virtuales, pero el problema en este momento es el siguiente. Tengo conectado el puerto Ext1 a un switch cisco 3750, ambos puertos, el GE 1/0/4 del cisco 3750 y el ext1 del IBM estan configurados como troncales. tengo instaladas 7 navajas. las navajas de encuentran en la vlan99 pero no las puedo alcanzar. espero puedan ayudarme

please, verify that:
both GE 1/0/4 and EXT1 are configured to allow also the vlan 99 (switchport trunk allowed vlan 1,99)
the INTA1-INTA7 ports are configured as "switchport access vlan 99" or "switchport trunk allowed vlan 1,99" if the OS want ot received the packets on VLAN 99 as tagged packets.
The "show interface info" command output will be useful to understand the behavior.
