Cisco 585 LRE CPE Device

The Cisco 585 CPE has four switched Fast Ethernet ports allowing customers to connect multiple devices

simultaneously. The 585 CPE also has two RJ-11 connectors: one for an analog phone and one for the LRE link

(same as the 575 LRE). A section of the top of the 585 CPE is indented to allow customers to place customized labels,

and the mounting templates on both the 585 CPE and 575 CPE are identical allowing customers to easily replace

existing 575 CPEs mounted under desks with Cisco 585 CPEs.

The 585 CPE is targeted towards customers who intend to deliver converged voice, video, and data services to several

devices such as computers, set-top boxes, IP phones, wireless access points, etc. In order to support converged

services such as voice-over-IP and video-on-demand, the 585 CPE supports 802.1p Quality of Service (QoS) with two

priority queues (threshold fixed at Class of Service [CoS] value of four) allowing voice and video traffic to be

prioritized over normal data traffic. There are two queues on the switch inside the 585 CPE, and if tagged traffic is

received on a Fast Ethernet port it will be placed in the high or low priority queue based upon tag. The 585 CPE does

not tag any packets, and the individual Fast Ethernet ports cannot be on separate VLANs.

The 585 CPE supports Private VLAN Edge that isolates the Fast Ethernet ports ensuring that traffic travels directly

from the entry point to the aggregation device through a virtual path and cannot be directed to another CPE Fast

Ethernet port. The speed of the four Fast Ethernet ports is set to auto-negotiate, and the duplex is set at half. The CPE

Ethernet ports can be enabled or disabled on a per-port basis when used in conjunction with the Catalyst 2950 LRE

switches but not the Catalyst 2900 LRE XL switches.
