Filed:

Nov 13, 2001

Appl. No.:

10/010811

Inventors:

Gabriel Lee - El Cerrito CA
David Langley - Los Gatos CA

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

G06F 15177

US Classification:

709220, 709223, 709224, 370395, 370397, 370399

Abstract:

A method and apparatus retrieves and stores configuration information for network endpoint devices from other devices in the network, such as a switch adjacent to the endpoint device. When the endpoint device establishes a connection with the network, it generates a sequence of SNMP getnext commands using the ILMI interface to obtain the configuration information from the network device. If the network device sends a trap to the endpoint device indicating a change has been made to the configuration parameters stored in the network device for a PVC, a series of SNMP getrequest commands are made using the ILMI interface to retrieve the configuration information for that PVC from the network device. If the endpoint device detects an interruption in communication with the network device, the endpoint device discards the information retrieved previously.
