Secure Shell (SSH) Public Key Authentication

DSA public key authentication is supported when using PuTTY SSH software to generate the private and

public key for the client and to access the switch. It is now possible to enforce the use of public key

authentication only on the switch. By default, both password and public key authentication are allowed.

Server Load Balancing (SLB)

Server Load Balancing (SLB) software provides a method to logically manage a group of physical

servers sharing the same content (known as a server farm) as one large virtual server (known as an

SLB cluster). SLB clusters are identified and accessed at Layer 3 by the use of Virtual IP (VIP)

addresses or at Layer 2 or Layer 3 by the use of a QoS policy condition. The OmniSwitch operates at

wire speed to process client requests addressed to the VIP of an SLB cluster or classified by a QoS

policy condition and send them to the physical servers within the cluster.

Using SLB clusters can provide cost savings (costly hardware upgrades can be delayed or avoided),

scalability (as the demands on your server farm grow you can add additional physical servers),

reliability (if one physical server goes down the remaining servers can handle the remaining

workload), and flexibility (you can tailor workload requirements individually to servers within a

cluster).

sFlow

sFlow is a network monitoring technology that gives visibility to the activity of the network, by providing

network usage information. It provides the data required to effectively control and manage the network

usage. sFlow is a sampling technology that meets the requirements for a network traffic monitoring solu-

tion.

sFlow is a sampling technology embedded within switches/routers. It provides the ability to monitor the

traffic flows. It requires an sFlow agent software process running as part of the switch software and an

sFlow collector, which receives and analyses the monitored data. The sFlow collector makes use of SNMP

to communicate with an sFlow agent in order to configure sFlow monitoring on the device (switch).
