VSC7438
32 Gbps Carrier Ethernet Switch with ViSAA™, VeriTime™, MPLS-TP, and L3 Routing Support
Microsemi's Carrier Ethernet switch family offers the highest performance, market-
ready solution for MEF CE 2.0 service delivery.
The VSC7438 Serval-2™ device targets IP Edge demarcation and access
equipment to deliver Enterprise and mobile backhaul. VSC7438 is based on
Virtualized Service Aware Architecture (ViSAA™), a silicon implementation that
offers an unmatched level of Service Edge and Carrier Ethernet Networking
features. ViSAA achieves wirespeed performance for even the most feature-rich
Carrier Ethernet (CE) services. VSC7438 also integrates VeriTime™, Microsemi's
patent-pending timing technology that delivers the industry’s most accurate IEEE
1588v2 timing implementation.
The VSC7438 Carrier Ethernet switch contains twelve 10/100/1000 Mbps SGMII/
SerDes ports, three 10/100/1000 Mbps QSGMII ports, and two 10 Gbps XAUI/
SFI ports. VSC7438 provides a rich set of Carrier Ethernet switching features such
as hierarchical QoS, hardware-based OAM (Ethernet and MPLS/MPLS-TP) and
SAM, protection switching, and Synchronous Ethernet. Using provider bridging
(Q-in-Q) and MPLS/MPLS-TP technology, VSC7438 delivers MEF CE 2.0 EVCs.
The Versatile Content Aware Process (VCAP™) architecture is scalable and flexible
for secure applications. It features advanced TCAM classification in both ingress
and egress. Per-EVC features include a rich set of statistics, OAM for end-to-end
performance monitoring, and dual-rate policing and shaping.
VSC7438 supports IPv4/IPv6 Layer-3 (L3) routing with up to 4K IPv4 (1K IPv6)
unicast LPM entries and 2K IPv4(512 IPv6) L3 multicast groups. L3 security features
include source guard and reverse path forwarding tasks.
VSC7438 supports Microsemi's application programming interface for easy
integration with third-party application software. The device also supports
Microsemi's CEServices application software, dramatically reducing customer
time-to-market.
