Metro Switching
Service provider networks are moving from circuit-based access to newer packet-based access that will require highly reliable intelligent switching, and at the same time demand resiliency and dependability. The xStack DES-3828P meets this demand by supporting industry standards for 802.1s* (multiple spanning tree), 802.3ad link aggregation for up to 32 groups, bandwidth rate limiting down to 64k, and support for an external redundant power option for added peace of mind. In addition the xStack DES-3828P offers Double VLAN Q-in-Q tagging*, which adds on an additional tag to a VLAN tag, expanding the VLAN space and allowing service providers to deploy their service quickly and securely. The xStack DES-3828P also incorporates advanced QoS support such as the ability to filter and forward traffic based on Layer 2/3/4, making it an ideal choice for VoIP, video, and audio services targeting business class customers.

Network Security
The xStack DES-3828P is equipped to handle many of today’s emerging security vulnerabilities. Up to 800 independent access control lists can be configured with the ability to filter and block traffic based on such criteria as: Port, MAC, 802.1p priority, VLAN, DSCP, IP address, Protocol type, and TCP/UDP port number and content, proving that the xStack DES-3828P provides unparalleled security in its class. In addition the xStack DES-3828P incorporates 802.1x port and MAC based RADIUS authentication for secure network logins and SSH / SSL for increased management security. Further, the xStack DES-3828P incorporates MAC-IP Binding and CPU protection to protect the CPU from broadcast, multicast, and Unicast flooding.
