LAYER 2 FEATURES
The StrataXGS supports Layer 2 switching capabilities in hardware for greater performance. These capabilities are, auto-
learning MAC addresses, address lookup, and packet forwarding. StrataXGS GE switches can support 4096 VLANs, 256
Spanning Trees, 256 Layer 2 multicast sessions, and 16384 Layer 2 switch table entries.
LAYER 3 FEATURES
At Layer 3, for increased performance, the hardware handles routing table lookup and forwarding. StrataXGS GE switches
can support 4096 Layer 3 routing table entries and 512 virtual router interfaces.
SECURITY
StrataXGS supports the IEEE 802.1x authentication framework for port-based network access control. Also, per-port
security is offered to avoid denial-of-service (DoS) attacks. This is achieved by denying access to certain MAC addresses
by programming bits in the routing table to be rejected.

Note The many rich features supported in the StrataXGS architecture are activated in different ways. Most
require some custom programming in addition to basic support in a StrataXGS chip.
