LACP between different speed ports

[abbas.ali]

In Cisco Catalyst switches, Is LACP doable between 1Gb and 10Gb ports.  In other words if I want to configure LACP between two Cisco switches.  Can I take (2) 1Gb and (2) 10Gb ports from each switch and configure LACP?

Hi,

No, you can not pair mismatch speeds in one bundle. etherchannel is doable between different speeds from 10Mbps to 10Gbps, but all the links in a bundle must be of a same speed and duplex configuration.

Hello

EtherChannel technology is not dependent on any type of media. it can be used with Ethernet running on copper wiring, or single-mode and multimode fiber, no problem.

Njein. depending on the hardware config, the 10G ports will fallback to 1G and thus create a 2x1G LACP.

If the hardware is fixed 10G, then the other comment comes into place, LACP needs same duplex/speed settings on both and all ends.
