Can you please let me know what is a layer 3 etherchannel called?

[Mark Malone]

its called a layer 3 etherchannel

[Charles Hill]

An etherchannel can be created with a maximum of 8 ports with an additional 8 backup ports.

Mark,

Are you sure the document you referenced that states 4 maximum ports for lacp is accurate?  I have not heard that restriction before and there are other documentation that states lacp supports 8 ports.

Understanding LACP

LACP allows you to configure up to 8 interfaces into a port channel.

Never had more than 4 in 1 etherchannel so i cant say from experience would have to check but from what your saying i checked again and yes theres other docs saying that you can have 8 , that could be just specific to that version of IOS i didnt check against chasis just checked maximum allowed ports specific for LACP and that came up
