Im thinking about moving over the foundry line b/c the pricing on those units. i plan on only using foundry at the access layer and keeping cisco at the distribution layer. Anyone have any thoughts about intermixing cisco and foundry devices?

Has anyone had any previous experience with these units? i was trying to find out if there are any HSRP VLAN limitations on these guys. I have several 3560's and they are limited to 32 HSRP VLAN's. http://www.cisco.com/en/US/products/ps6021/index.html
