CISCO SYSTEMS COMPLETES ACQUISITION OF AURORANETICS

SAN JOSE, Calif., Aug. 23, 2001-- Cisco Systems, Inc., today announced it has
completed the acquisition of privately held AuroraNetics, Inc. of San Jose,
California. AuroraNetics is a developer of 10 Gigabits per second (Gbps) silicon

On July 11, 2001, Cisco announced a definitive agreement to acquire
AuroraNetics. AuroraNetics' silicon technology is used in data-optimized fiber
rings known as Resilient Packet Rings (RPR). The acquisition of AuroraNetics
complements Cisco's existing RPR-based products (known as Dynamic Packet
Transport) by enabling the technology to scale from the current 2.5Gbps up to
10Gbps. This acquisition is being accounted for as a purchase.
