Catalyst 3650 and SG200 Etherchannel

[amantsios]

Hello,

recently we bought 2 SG200 to expand our network to Gigabit.We own 1 Catalyst 3650.

We tryed to Etherchannel between the Catalyst and one SG200 but with no luck.

At Catalyst i created the port channel

interface Port-channel1

switchport mode access

and put 4 ports on it

interface GigabitEthernet0/45

switchport mode access

channel-group 1 mode on

!

interface GigabitEthernet0/46

switchport mode access

channel-group 1 mode on

!

interface GigabitEthernet0/47

switchport mode access

channel-group 1 mode on

!

interface GigabitEthernet0/48

switchport mode access

channel-group 1 mode on

when i do show interface port-channel 1 i get that

Port-channel1 is up, line protocol is up (connected)

  Hardware is EtherChannel, address is 001a.a24d.00ae (bia 001a.a24d.00ae)

I can see that the port-channel is 4Gbit but into the SG200 web interface the Link stays at 1Gbit

I also tryed speed tests but the link is still 1Gbit.

I also giving you 2 screenshots from the sg200.
Am i doing something wrong?

Do you have any suggestions?

Is able sg200 to create etherchannel with the Catalyst?

Thanks in Advanced

See from the output of SG200, LACP is Disabled.

I would suggest,

1. Enable LACP oin SG200

2. Used command "channel-group {Number} mode active" on CISCO side.

If you think the steps mentioned helped you, please rate the post.

Hello,

i tryed that also before but with no luck.

When i do that i get Success but LACP is still disabled.

Check out the screenshot.

Any other suggestions?

Thanks

HI,

I see the LACP checkbox unchecked, please correct that.

Cheers,

Sunil

When i check the Enable box and then hit Apply i got the screenshot i just send.

It says Success but it doesn't enable it.

From CISCO side, could you please share the output of "sh ether summ"

Regards,

Sunil
