non stack switch setup the etherchannel(LACP) to offside switch 9200

[Xx20GaryL21xX]

Hi All,

We would try to make a EtherChannel (LACP) on Te1/1/1 Switches (9200) From Main site to backup site.

However, it shows up have this error "suspended: LACP currently not enabled on the remote port." Although we add Channel-protocol LACP on backup site and Shut & no shut. It still not solve the issue.

1. Local Etherchannel LACP are working fine on Main Site and backup site.

2. The new connection of Fiber channel (1570 CWDM) added on Main site Switch 1A, 1B and backup site Switch 2A, 2B

    There are working fine when the single internetwork connected on main site and backup site (non stackwise).

1. Is it possible to config the Etherchannel configuration as following?

Switch 1A => LACP (PO3 active passive) <= Switch 2A

Switch 1B => LACP (PO3 active passive) <= Switch 2B

2.We use the current interworking setting with Fiber channel to Backup site without etherchannel.

3. We wait until stack cable come for the stack together on 9200 at main site and backup site. After that we setup etherchannel to Main site and backup site switches. 

Main Site  (non-stackwise)             Internetwork(Main_MetroE)     Backup site (non-stackwise)  

Switch 1A (9200)                             Te1/1/1 ===== Te1/1/1                Switch 2A (9200)                                            

      ||                                                                                                              ||

P47 - 48 (LACP active passive)                                                        P47 - 48 (LACP active passive)

      ||                                            Internetwork(Backup_MetroE)                     ||

Switch 1B (9200)                             Te1/1/1 ===== Te1/1/1                 Switch 2B (9200)

Do anyone have any ideal or recommendation?

Thanks

Hi Gary,

In order for this to work, the switches in each location need to be configured in a Stack. The first switch in the stack will be te1/1/1 and the second switch in the stack will be 2/1/1. See below:

Main Site  (StackWise)             Internetwork(Main_MetroE)     Backup site (StackWise)  

Switch 1A (9200)                             Te1/1/1 ===== Te1/1/1                Switch 2A (9200)                                            

      ||                                                                                                              ||

P47 - 48 (LACP active passive)                                                        P47 - 48 (LACP active passive)

      ||                                            Internetwork(Backup_MetroE)                     ||

Switch 1B (9200)                             Te2/1/1 ===== Te2/1/1                 Switch 2B (9200)

Hi Reza,

Thanks for the advice.

As you said,

It must have stack on both switch main site and backup site.

Currently, I only can do which able to configure on local site with dual link etherchannel on switch 1A, 1B and backup site switch 2A, 2B

Otherwise, it keeps to show the error: suspend lacp is not enable at remote port, if I setup etherchannel without Stack on switches. 

Now I only able to configure the trunk mode at te1/1/1 on switch 1 and 2's fiber ports before the stack modules and cables arrive.

Thanks

Hi Gary,

Otherwise, it keeps to show the error: suspend lacp is not enable at remote port, if I setup etherchannel without Stack on switches. 

That is the correct behavior. You can not create an Etherchannel without the switches in each location being configured in a stack. Remember, when you configure 2 switches in a stack, they logically become one switch (hence 2/1/1 in my post) and that is why the Etherchannel config will work. If not, you have 2 separate switches.

Now I only able to configure the trunk mode at te1/1/1 on switch 1 and 2's fiber ports before the stack modules and cables arrive.

That is correct. If you connect all 4 switches together like the way you have it in your first post, to prevent a loop, STP will block the redundant link.

As per my understanding - If they are not stacked, then you need to use trunk port for now, until it get stacked.
