The STE-228-X3X1 is a Telecom grade 24 port 10/100Base-Tx + 4 Gigabit port combo layer 2 optic switch that comes with a couple of layer 3 features. The STE-228-X3X1 is expecially designed for Telecom grade optic applications.

The STE-228-X3X1 is the most advanced multi-layer,high performace 24 x 10/100 Mbps ports plus 4 port

Gigabit uplinks optic fiber switch. With an aggregate line rate of 9.5 Mpps, the STE-228-X3X1 offers switching on both L2 and L3 traffic. Filtering, policing, priority tagging can be performed in real time with no impact on forwarding performance.

Supporting the latest Metro Ethernet L2 VPN applications,the STE-208-X3X1 offers double 802.1Q VLAN stacking, also known as Q-in-Q. This allows enterprise and service provider networks to breakthrough the 4K VLAN tag limitation. Furthermore,STE-228-X3X1 also provides MPLS Tunnel/VC packet labeling for standards-based IETF L2 VPN via MPLS.With 8 Class of Service (CoS) queues via SP, RR, WFQ and WRR distribution, the STE-228-X3X1 enables full range of service applications such as low latency VoIP and real-time video, as well as mission critical data.

Optimized for the most demanding network switching requirements, the STE-228-X3X1 integrates auto-

learning/aging MAC and IP LPM tables. Advanced Ethernet features such as multiple and rapid spanning

tree (802.1s and 802.1w), flow control (802.3x), prioritization (802.1p) and 9K jumbo frame are fully integrated. All L2/L3 traffic is switched at line rate. For load balancing as well as redundancy purposes, ECMP and WCMP are incorporated. Up to 32 trunk groups (8 links per group)can be assigned for link aggregation (802.3ad).

Providing line-rate packet filtering and classification, the advanced Fast Filter Processor (FFP) offers ContentAware network processing per port. It supports TOS/DiffServ, rate limiting, policing, shaping, metering, scheduling, priority tagging, and remapping down to flows as small as 64 kbps, making it ideal for committed bandwidth usage and firewall applications.

Designed for increasing multicast applications, the STE-228-X3X1 switches all L2/L3 multicast packet sizes at line rate. IPMC packets are hardware replicated up to 8 and 32 VLANs across the Fast and Gigabit Ethernet ports, respectively. Multicast traffic can also be managed by three port filtering modes to control the distribution behavior.
