Overview

 

 

Layer 2 Features

Auto-Negotiation

Every 10/100 port on the Cajun P330 supports Auto-Negotiation which automatically detects and supports the operating mode and speed of a connected device. Auto-negotiation is also supported on the Gigabit Ethernet ports for flow control mode only.

This means that you can simply connect the Cajun P330 to Ethernet or Fast Ethernet equipment at full or half duplex without configuration.

Congestion Control

Congestion control is a key element of maintaining network efficiency as it prevents resource overload.

The Lucent Cajun P330 supports congestion control on all Ethernet ports, using the following:

•Back Pressure in half duplex mode

•IEEE 802.3x Flow Control in full duplex mode

VLANs

The Cajun P330 VLANs are fully IEEE 802.1Q compliant and can handle up to 3k tagged VLANs.

Special VLAN (Virtual Sideband) for management provides physical security for key applications.

Link Aggregation Group (LAG)

LAG provides increased bandwidth and redundancy for critical high-bandwidth applications such as inter-stack links and connections to servers. You can aggregate the bandwidth of up to eight 10/100Base-Tx ports, two 100Base-FX or 1000Base-X ports.

Load sharing ensures that if one of the port connections fails, the other connections will assume the load seamlessly. Load balancing guarantees that the traffic load at any level will be evenly divided among all the LAG links.

LAG and Port Redundancy

Redundancy can be implemented between any two ports in the same stack. You can also assign redundancy between any two LAGs in the stack or between a LAG and a port.
