Appl. No.:

09/299945

Inventors:

Krishna Rao Chennapragada - Milpitas CA
Keith Waldorf - Santa Clara CA

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

G06F 1516

US Classification:

709228, 709223, 709224, 709225, 709226, 709227, 709236, 709202, 709203, 709206, 709217, 709219

Abstract:

A mechanism for supplying a stream of data to a browser is provided. The browser periodically refreshes a frame document, transmitting a request for the frame document to an HTTP server. When a network element receives a request from a browser for a frame document, it generates a new frame document, and supplies it to the browser. The new version of the frame document may include new definitions for functions, that, as redefined, reflect the current status of a network element. The updates may be retrieved by invoking functions.

International Classification:

G06F015/177

US Classification:

Abstract:

A group of network devices, such as Ethernet switches, are logically configured as a single cluster, with one commander device and one or more expansion devices. Each device in the cluster contains an embedded HTML server that facilitates configuration and management of the network device via a management station running a Web browser. Each device in the cluster is identified by a unique Universal Resource Locator (“URL”). However, only the cluster commander is required to have an IP address. The cluster commander redirects and translates configuration and management requests from the Web browser on the management station so that requests are processed by the appropriate device in the cluster. The exchange of information between the Web browser on the management station and the devices in a cluster is accomplished via redirection of HTTP GET and POST methods. This provides a consistent, device-independent interface between the device and the Web browser on the management station.
