Aggregated Ethernet

Svarer til etherchannels på cisco kasser. Altså en bundling af flere links for at øge hastigheden. Juniper bruger IEEE 802.1ad protocollen og understøtter også overvågning med LACP.[1]
Der kan maks være 10 interfaces i en aggregated bundle[2]
Læs mere on Juniper load balancing her.

Juniper konfiguration

I dette setup er en Juniper SRX100 forbundet til en Cisco 2960G Switch, fra fe-0/0/1 til Gi0/1 og fe-0/0/2 til Gi0/2

Konfigurere bundling devices

For at konfigurere aggregated porte på juniper skal der reserveres resourcer til det via chassis aggregated-devices. Her er der konfigureret en bundle:

root@SRX100> <input>show configuration chassis</input>
aggregated-devices {
    ethernet {
        device-count <notice>1</notice>;
    }
}

Bundle interfacet

der skal oprettes et aggregated ethernet interfaces som konfigureres som et almindelig standalone interface. Her interfacet konfigureret med trunk og LACP:

root@SRX100> <input>show configuration interfaces ae0</input>
<notice>aggregated-ether-options {
    lacp {
        active;
    }
}</notice>
unit 0 {
    family ethernet-switching {
        port-mode trunk;
        vlan {
            members all;
        }
        native-vlan-id 1;
    }
}

Fysiske interfaces

De fysiske interfaces skal kædes sammen med bundle interfacet.

rooth@SRX100> <input>show configuration interfaces fe-0/0/1</input>
fastether-options {
    <notice>802.3ad ae0;</notice>
}

root@SRX100> <input>show configuration interfaces fe-0/0/2</input>
fastether-options {
    <notice>802.3ad ae0;</notice>
}

traceoptions for lacp finde også[3].

Cisco Switch konfiguration

Konfigurationen af EtherChannel på Cisco IOS kaldes for etherchannels eller port-channels
