Description
The MVTX2800AG family is a group of 8-port 1000 Mbps non-blocking Ethernet switch chips with on-chip
address memory. A single chip provides a maximum of eight 1000 Mbps ports and a dedicated CPU interface
with a 16/8-bit bus for managed and unmanaged switch applications. The VTX2800 family consists of the
following four products:
•
•
•
•
VTX2804 8 Gigabit ports Managed
VTX2803 8 Gigabit ports Unmanaged
VTX2802 4 Gigabit ports Managed
VTX2801 4 Gigabit ports Unmanaged
The MVTX2802AG supports up to 64K MAC addresses to aggregate traffic from multiple wiring closet stacks.
The centralized shared-memory architecture allows a very high performance packet-forwarding rate of 5.952M
packets per second at full wire speed. The chip is optimized to provide a low-cost, high performance
workgroup, and wiring closet, layer 2 switching solution with 4 Gigabit Ethernet ports.
One Frame Buffer Memory domains utilize cost effective, high–performance ZBT-SRAM with aggregated
bandwidth of 8.5Gbps to support full wire speed on all external ports simultaneously.
With Strict priority, Delay Bounded, and WRR transmission scheduling, plus WRED memory congestion
scheme, the chip provides powerful QoS functions for convergent network multimedia and mission-critical
applications. The chip provides 8 transmission priorities and 2 level drop precedence. Traffic is assigned its
transmission priority and dropping precedence based on the frame VLAN Tag priority or DS/TOS fields in IP
packets.
IP multicast snooping provides up to 64k simultaneous IP Multicast groups. With 4K IEEE 802.1Q VLANs, the
MVTX2802AG provides the ability to logically group users to control multicast traffic.
