mirroring, switching, static routing, sFlow, multicast snooping across stack-members
Support for automatic failover of active controller and hot insertion and removal of
stack-members
Layer 3 Capabilities
Base Layer 3 software supporting features such as static routes, routing between directly
connected subnets, RIPv1/v2 (announce only), virtual interfaces, VRRP and ECMP
Optional Edge Layer 3 Premium (EPREM)* upgrade providing dynamic Layer 3 routing via
OSPF v2 and RIP v1/v2 in addition to features supported in base Layer 3 software.
