13description: |
14  The SparX-5 Enterprise Ethernet switch family provides a rich set of
15  Enterprise switching features such as advanced TCAM-based VLAN and
16  QoS processing enabling delivery of differentiated services, and
17  security through TCAM-based frame processing using versatile content
18  aware processor (VCAP).
19
20  IPv4/IPv6 Layer 3 (L3) unicast and multicast routing is supported
21  with up to 18K IPv4/9K IPv6 unicast LPM entries and up to 9K IPv4/3K
22  IPv6 (S,G) multicast groups.
23
24  L3 security features include source guard and reverse path
25  forwarding (uRPF) tasks. Additional L3 features include VRF-Lite and
26  IP tunnels (IP over GRE/IP).
27
28  The SparX-5 switch family targets managed Layer 2 and Layer 3
29  equipment in SMB, SME, and Enterprise where high port count
30  1G/2.5G/5G/10G switching with 10G/25G aggregation links is required.
