Overview

• Overview: A general description of the features of the Lucent Technologies’

• Installation: Instructions for getting the Cajun P115G Stackable Switch and Cajun

Description

The Cajun P115G Stackable Switch is part of the Cajun P110 Switching System family
of workgroup switches. The Cajun family is composed of high-performance workgroup
switches, which may be used singly or stacked in any combination to make up a multi­protocol, non-blocking, scalable switch.

The Cajun P115G is a workgroup switch with 24 ports divided into three shared
groups and an additional Ethernet/Fast Ethernet uplink port which can be either
copper or fiber-optic. The three groups consist of eight Ethernet/Fast Ethernet
(10/100BASE-T) ports each. The shared ports are ideal for workgroup connectivity,
while the uplink port can be used for high performance workstations or uplink.

When operated as part of a stack, a Cajun P110 NMA to manage the switches. The
units are physically linked using the Cajun P110 Exoplane™, which makes up a multi­gigabit, non-blocking backplane. Any combination of two, three or four Cajun switches
can be stacked, and up 32,000 MAC addresses per stack are supported.

The uplink port can run at full or half duplex. Shared ports run in half duplex mode
only, and setting the speed (10 or 100 Mbps) operates at group level. With a Cajun
P110 NMA installed, the UTP uplink port can perform standards-based auto­negotiation. Redundancy on the uplink ports can be defined via CajunView, Lucent
Technologies’ SNMP-based management system. A redundant power supply may be
used for enhanced fault tolerance.

The Cajun P115G uplink port can use Lucent’s flow control mechanism to eliminate
packet loss. An automatic fairness mechanism ensures that all ports gain fair access to
the Cajun P110 Exoplane, even at very high network utilization. Congestion
management works both on full and half duplex ports, and ensures no packet loss
should the buffers become saturated during peak load conditions.

Cajun switches are fully manageable, using CajunView™, and may be monitored using
the SMONMaster™ Switch Monitoring Application.
