 ====== Extreme Networks  ======
+{{:extreme.png|}}
+===== Hardware =====
+    * BlackDiamond: Chassis-based high-port density switches for Carrier-Ethernet service providers and enterprise core
+    * Summit: Standalone switches from L2 100Mbps to L3 10Gig top-of-rack datacenter switches.
+    * ReachNXT: Port Extender - Manageable by an access switch via XOS
+    * SummitWM: Wireless controllers
+    * Altitude: Wireless Access Points
+    * Sentriant NG: Intrusion Protection System (IPS)
+    * Sentriant AG: Network Access Controller (NAC)
+===== Software =====
+    * ExtremeWare is VxWorks based = first generation of Extreme networks operating system
+    * ExtremeXOS = 2nd Generation OS based on Linux kernel and BusyBox
+    * EPICenter = Network Management Tool
+===== Configuration =====
+Switch CLI prompt is driven from SNMP host name value \\
+Space bar to go to BootROM: for return to factory default configuration: ''config none'' \\
+**Extreme FDB** = Forwarding Database for MAC addresses - 300 Sec Aging timer per MAC \\
+==== IP FDB (L3) for IP forwarding ====
+<code>
+    show iparp
+    show fdb
+    create fdbentry
+    delete fdbentry
+    disable learning
+    enable learning
+</code>
+   # configure ports 1 vlan accounting unlimited-learnings
+   # configure ports 1 vlan accounting learning-limit 3 (use aging timer also) (only for dynamic entries)
+**Lock-learning (sticky mac)**
+<code>
+# configure ports 1 vlan VLAN1 lock-learning
+# configure ports 1 vlan VLAN1 unlock-learning
+    show vlan default security
+</code>
+==== ELSM (Extreme Link Status monitoring) ====
+gets link status from other-end
+<code>
+    enable elsm ports
+    disable elsm ports
+    configure elsm ports
+    clear elsm ports
+</code>
+==== VLANs ====
+. Port-based
+. 802.1Q Tagged VLAN
+. Protocol-based VLAN
+<code>
+              create vlan vlan_name
+              delete vlan vlan_name
+              configure vlan vlan_name add ports
+              configure vlan vlan_name delete ports
+              disable vlan vlan_name
+              enable vlan vlan_name
+              configure vlan vlan_name tag <tag_value>
+              configure vlan default delete port 7
+              configure vlan ENGINEERING add port 7 untagged
+              configure vlan ENGINEERING add ports 2,3 tagged
+              show vlan ENGINEERING
+              BPDU –> vlan0
+</code>
+==== Port Sharing (Aggregation) LAG ====
+    enable sharing 1 grouping 1-4 algorithm address-based lacp
+    show port sharing
+==== Port Settings ====
+   enable lldp port all
+   show ports configuration no-refresh
+   enable jumbo-frame ports all
+   show vlan VLAN1 security
+    * spanning-tree is disabled by default
+    * EMI-STP Encapsulation - Extreme Multi Instance Spanning Tree - VST+ additional header
+==== EAPS - Ethernet Automatic Protection Switching (Ring) ====
+    * Ring Topology
+    * L2 Protocol - Multicast MAC
+    * EAPS version 2 (advanced feature - EAPS shared port for preventing superloop)
+    * 50 ms failover
+    * Device Roles: Master node, Transit nodes
+    * Primary/secondary port on each switch
+    * Master blocks its secondary port
+    * Control VLAN and Protected VLAN (one Control VLAN per EAPS domain)
+    * EAPS flush FDB when there's a topology change
+<code>
+        create vlan control_vlan_name
+   configure vlan control_vlan_name tag vlan_tag
+   configure vlan control_vlan_name add port <primary.secondary> tagged
+        create eaps <name>
+        configure eaps <name> mode master|transit
+        configure eaps <name> primary port <port number>
+        configure eaps <name> secondary port <port number>
+        configure eaps <name> add control vlan control_vlan_name
+        configure eaps <name> add protect vlan <name>
+        enable eaps
+        enable eaps <name>
+        configure eaps fast-convergence [off|on] -> additional 250ms
+        configure eaps name failtime expiry-action open secondary-port > by default sends alert!
+</code>
+==== EAPS with a Shared Port ====
+    * Configure partner
+    * Configure controller port
+    * link-id must be same on both switches
+==== SummitStack ====
+    * Should have same image:
+      ''download image <ip> <file> slot <slot-number>''
+    * 40Gbps full duplex capacity per switch
+    * MAX: 8 devices
+<code>
+              enable stacking
+              show stacking
+              show stacking configuration
+              configure stacking easy-setup
+</code>
+==== IP Routing ====
+    * By default is disabled
+          enable ipforwarding
+          configure iproute add x.x.x.x/x y.y.y.y
+          show ipconfig
+    * In new vlan ip forwarding might be disabled make sure to check.
+          show iproute
+          show ipstats
+    * icmp is enabled by default
+==== OSPF ====
+    enable ipforwarding
+    configure ospf routerid 1.1.1.1
+    enable loopback vlanname (if you want to have loopback)
+    configure ospf address VLAN1 area 0.0.0.0
+    configure ospf address VLAN2 area 0.0.0.0
+    enable ospf
+    show ospf
+    show ospf area 0.0.0.0
+    show ospf neighbors
+    show ospf lsdb
+    * Redistribution is disabled and is configurable by policy files.
+    * Core license required for OSPF DR/BDR function.
+    * on edge / advanced edge license: we can not have DRs so priority:0
+==== ESRP ====
+Extreme Standby Routing Protocol - ESRP is extreme protocol for redundancy something like VRRP
+==== QOS ====
+    * No much QOS support
+    * Traffic shaping is called metering
+    * 8 queue per interface
+    * Queue 1 and 8 are used by default (2q)
+==== Useful hints ====
