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 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

Hi Alexander,
Please note that Etherchannel "mode on" will only work between Cisco devices. Therefore, could you try using LACP by configuring "mode active" on the Cisco switch, and enabling LACP (also known as LAG or 802.3ad) on the SG200 device?
Please refer to the following documentations as well.

Best regards,

Mode on should work on servers or cisco switches. PAGP will only work between cisco switches because it is cisco proprietary.

Did you run a BW test? Maybe it's just a BUG in the webview. As long as the Catalyst see the link to 4Gbps I see no problem.
