Training: Enterprise Network Switches for IP Video
Author: Benros Emata, Published on Sep 07, 2010
Many surveillance systems use non-enterprise class switches. These switches are simple to administer as they typically rely on GUI driven interfaces for configuration and management. (As an example, see our test of Cisco-Linksys's basic managed switch). However, they lack more advanced features and functionalities important for large-scale IP surveillance.
This training focuses on command line interface (CLI) driven configuration interfaces commonly found on enterprise-class switches. Familiarity and proficiency with CLI based enterprise switches allows for more sophisticated design options and enhances integration with corporate networks.
This training provides 80 minutes of video tutorials on configuring enterprise class switches for IP video. We demonstrate network configuration concepts using the popular Cisco IOS command line interface (CLI) as a representative enterprise level switch.
Skills developed in using the Cisco IOS CLI will transfer to almost any other vendor's CLI such as Hewlett Packard, Huawei, Enterasys, Adtran, Foundry, Alcatel-Lucent, Motorola, Riverbed, and others. These and other vendors implement CLIs that are either very close copies of the Cisco CLI or of varying likenesses to it. Vendors may even market claims of Cisco IOS 'likeness' to attract IT purchasers.
For stand-alone IP video systems, enterprise-class switches offer increased PoE reliability, more extensive and proven support for multicast technologies, more granular QoS controls, layer 3 routing possibilities, an overall depth of support for open standards, and more intensive tech-support for advanced deployments.
Moreover, for projects requiring IP video systems integration into corporate networks, a vendor preferred enterprise class switch is often times mandated. Corporate IT departments have many well-founded reasons to maintain as homogeneous a network as possible. These policies reduce risk of interoperability issues between devices, help assure that new devices are supported by network wide monitoring and management systems, and capitalize on existing knowledge and familiarity with products, by avoiding training for new systems or products.
