lacp across switches

lacp across switches

I have a set of a few 2848 switches that are currently stacked.  I want to know if its possible to get a LACP team on a server to connect to multiple ports on both switches and get redundancy?  Basically server A NIC1,2 to Switch A, and NIC 3,4 to Switch B.  The OS is configured for lacp and sees the connection plugged in.  Right now, I get dynamic trunks, and can't set any vlans other than the default.  I know this is a "feature" of the dynamic trunks.  

 

TIA,

Carlos.

No, the 2848 "stack" doesnt support this cross-stack trunk / DDR.

2800 only does IP stacking, meaning the only advantage  you get is management through a single IP address. 

 

What you're looking for can be done with Distributed Trunking or IRF.  The former is available for example for K-platform switches (3500-series, 5400-series etc.), the latter is a Comware device feature (ex-3Com/H3C switches).
