LACP with 10GB interfaces between 3750X and 2960S switches

[rezende.c]

Hi all,

   I need to know if is possible to do a LACP using  2 x 10GB between 3750X and 2960S (WS-C2960S-48LPD-L) switches.

thanks,

Claudio

Hello Claudio,

LACP is listed in C2960 datasheet

http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps6406/product_data_sheet0900aecd80322c0c.html

However,

C2960 configuration guide says:

>>The EtherChannel provides full-duplex bandwidth up  to 800 Mbps (Fast EtherChannel) or 8 Gbps (Gigabit EtherChannel)  between your switch and another switch or host.

http://www.cisco.com/en/US/docs/switches/lan/catalyst2960/software/release/12.2_25_fx/configuration/guide/swethchl.html

So I'm not sure that the C2960 does not support bundling of the 10GE uplink ports.

>>

EtherChannel for enhanced fault tolerance and for  providing up to 8 Gbps (Gigabit EtherChannel) or 800 Mbps (Fast  EtherChannel) full-duplex bandwidth among switches, routers, and servers  

I would say bundling of the 10GE uplinks is not supported

Hope to help
