Cisco Systems Inc. today unveiled three new modules for its Catalyst 5000 LAN switches that feature enhanced quality-of-service capabilities and greater port density.
The new products include a 24-port 10/100 RJ-45 module, a 36-port 10/100 RJ-21 module and a 24-port 100FX MT-RJ multimode fiber module. Quality-of-service (QoS) features on the new modules include Weighted Random Early Detection drop threshold management. WRED drops low priority packets to avoid congestion.
Other QoS features include wire-speed Layer 3 Forwarding, Fast EtherChannel, 802.1Q/p and Cisco's InterSwitch Link protocol, which tags packets with virtual LAN identification information.
These features are designed to enable users to classify traffic into one of multiple priority classes and manage those classes to ensure that applications such as voice are appropriately prioritized. The 36-port 10/100 RJ-21 module and the 24-port 100FX MT-RJ module increase the Catalyst 5000 Family's maximum port density by 50% and 100%, respectively.
The 24-port 10/100 RJ-45 module lists for $4,995; the 36-port 10/100 RJ-21 module lists for $7,495 and the 24-port MT-RJ 100FX multimode fiber module lists for $12,495. All modules are shipping now.
