"LIST PRICE" is the suggested retail price provided to Super Warehouse by our suppliers.
Super Warehouse makes no claim that these products have been sold or offered for sale at the list price.
The retail price in your area may be substantially different.
It is not possible for Super Warehouse to know if the merchandise has been sold at the list price
at any time, any where, as we sell our products over the internet both nationally and internationally.
"Total Savings" reflects the difference between our price and the supplier provided list price shown on our sites.
Since actual retail pricing in your area may be different than the list price shown on our site,
you may not actually realize a savings of this amount.
You may make a comparison yourself by checking the prices of your local retailers
or other internet companies before buying from Super Warehouse.
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.
