Confidential

Responsibilities:

• File Upload/Download: dis feature gives a provision for a Network Administrator or an end user to upload/download code, configuration files, logs etc. over tftp, http, scp and sftp on a switch.
• Traffic Load Statistics: dis feature is to provide Network Administrator with teh traffic inflow and outflow in packets per second and bits per second collected periodically.
• DHCP Client Identifier: dis option is used by DHCP clients to specify their unique identifier which is used by DHCP Server in differentiating teh hardware from different vendors and upload teh appropriate configuration onto teh switch/router through AutoInstall.

Confidential

Responsibilities:

• Implemented teh Web interface for LLDP and LLDP-Med used by network devices for advertising their identity, capabilities, and neighbors on an IEEE 802 local area network, principally wired Ethernet.
