We swapped our Cisco 3750 network for an Extreme network in the summer. Five X440 stacks and an X620 core. After the switches were provisioned I noticed %CPU spikes around 60% in the X440 stacks. I was not too concerned at the time because our Cisco 3750s ran permenantly above 80% CPU. The Extreme Networks Summit X440 series is enabling fine grained Quality of Service (QoS), stacking, high availability features and identity aware security in a compact, cost effective switch. Standards-based PoE/PoE+ support (802.3af/802.3at) allows the Summit X440 series to support the large-scale rollout of converged network devices such as ExtremeXOS supports the SummitStack-V capability using 2 of the SFP+ ports on the X440-G2 as stacking ports, enabling the use of standard cabling and optics technologies used for 10 GbE SFP+, SummitStack-V provides long-distance stacking connectivity of up to 40 km while reducing the cable complexity of implementing a stacking solution. Beginning with the ExtremeXOS 12.5 release, the term Summit Family Switches includes the Summit X440, X460, X460-G2, X480, X670, X670-G2, and X770 switches. A SummitStack is a combination of up to eight Summit family switches (excluding the Summit X440-L series) that are connected together. The Summit X430 leverages a compact 1RU and 10-inch deep form factor, along with a low volume operating mode that makes it ideal for open office and wiring closet environments. Summit X430 series switches support up to 4 fixed front panel 100/1000BASE-X (SFP) unpopulated ports (two SFP ports on the 8 port PoE+ switch) that can be utilized for Standards-based PoE/PoE+ support (802.3af/802.3at) allows the Summit X440 series to support the large-scale rollout of converged network devices such as IP telephones, wireless access points as well as physical security devices such as video cameras. You can install a X440-G2 Series switch in a rack. There are four possible rack mounting configurations, depending upon whether: • The switch I/O ports or the power supply side of the device face front. • The device is mounted flush with the rack posts or mid-mounted. Secure the X440-G2 Series switches to the Rack Initial Network Connection and Configuration Once you have connected power to the switch and verified LED activity, complete the setup process as follows: Connect a management station to the console port using either an Ethernet to serial adapter or DB-9 serial cable. Verify that the system LEDs are on (solid green or blinking green). The Avaya C363T-PWR Converged Stackable Switch, Extreme Networks Summit X450e-48p and BlackDiamond 12k switches are connected to each other in a full mesh topology.

EventTracker monitors the activity occurring in Extreme Summit x440 like user logon/logoff activities, authentication failure, and port status monitoring. EventTracker helps you to visualize the Extreme Summit x440 activities in the dashboard. Connecting. All commands to the Extreme switches are transmitted via a Command Line Interface (C
