Cara Configurasi Extreme.........

Setelah beberapa minggu yang lalu mengikut seminar tentang Extreme di tambah dengan beberapa tutorial mengenai produk dari Extreme Network;

Sepengetahuan saya tentang Switch dari pabrikan Extreme Network ;



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(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   

   show iparp 

    show fdb 

    create fdbentry 

    delete fdbentry 

    disable learning 

    enable learning

# 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)  

# configure ports 1 vlan VLAN1 lock-learning  

# configure ports 1 vlan VLAN1 unlock-learning 

    show vlan default security

ELSM (Extreme Link Status monitoring) 

gets link status from other-end 

     enable elsm ports 

    disable elsm ports 

    configure elsm ports 

    clear elsm ports 

VLANs

1. Port-based
2. 802.1Q Tagged VLAN
3. Protocol-based VLAN 

        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  

        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

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

 create vlan control_vlan_name  

   configure vlan control_vlan_name tag vlan_tag  

   configure vlan control_vlan_name add port tagged 

        create eaps  

        configure eaps mode master|transit 

        configure eaps primary port  

        configure eaps secondary port  

        configure eaps add control vlan control_vlan_name 

        configure eaps add protect vlan  

        enable eaps 

        enable eaps  

        configure eaps fast-convergence [off|on] -> additional 250ms 

     configure eaps name failtime expiry-action open secondary-port > by default sends alert!

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 slot

• 40Gbps full duplex capacity per switch
• MAX: 8 devices 

     enable stacking 

        show stacking 

        show stacking configuration 

        configure stacking easy-setup

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)
