Not only do they support redundant power , but also every other major component is redundant . Within the Cisco MDS 9000 Family of switches , information retrieved from both of these sources is used to map the topology of the fabric as it is seen from a Cisco MDS 9000 Family switch . With these macros , users can consistently and reliably configure essential security , availability , quality of service , and manageability features recommended for Cisco Business Ready Campus solutions with minimal effort and expertise . The Cisco Catalyst 4500 Series provides an ideal branch-office solution capable of meeting the needs of both small and large operations , as well as small-enterprise applications . Figure 6 shows these three windows . In the long haul , the newspapers will realize this and make it central to their survival . This design approach happens to be the most common design model used for Data Centers today . Each switch can operate as both a master controller and a forwarding processor . Using the routing table that Cisco IOS Software builds to define configured interfaces and routing protocols , the Cisco Express Forwarding architecture creates Cisco Express Forwarding tables and downloads them into the hardware forwarding engine before any user traffic is sent through the switch . In effect , Service OAM provides end-to-end manageability and visibility of Ethernet connections over any transport infrastructure ( such as MPLS , Virtual Private LAN Services [ VPLS ] , and provider bridges ( IEEE 802.1ad ) . The general deployment phase lasts for 18 to 24 months , and product defects in this phase are addressed in maintenance releases . While these services can be addressed by implementing standalone appliances , the Catalyst 6500 offers the added advantage of integrated these services into the switch chassis . These resources could be physical in nature or a virtual representation as in the case of storage virtualization . Engineering will no longer actively apply any defect repairs to the release , regardless of origin or severity ( except for security defects ) . This means that anybody with Internet access can find a wide variety of tools and vulnerabilities to exploit . Many of these approaches blur the boundaries between SAN security , best-practice SAN design , and high-availability SAN design , but all are important from the perspective that a correctly configured , secure switch can help prevent both deliberate and unintentional disruptions . A major release usually occurs every 12 to 16 months . This condition is avoided by ensuring that voice traffic is properly classified and prioritized throughout the network . If a community string with read-only privilege is used at the time of discovery , any attempt to provision ( zone configuration ) the switch will fail with an ambiguous message . As an example the number of hosts infected by the " SQL slammer " worm doubled every 8.5 seconds and the traffic that it generated could grow to saturate a 1-Gbps link in less than a minute . As a result , the market has a native tendency to revert to these structural dynamics . After FCS of each minor release , there is an initial deployment phase in which product defects are addressed in maintenance releases every 4 to 6 weeks . Baseline thresholds create a threshold that adapts to the typical traffic pattern for each link for the same time window each day , week , or every two weeks .
