Juniper – Catalyst 2900XL Etherchannel Load Balancing

Posted on January 31, 2008. Filed under: Cisco, Juniper |

Running for couple months….
Eventually, we are close to equal load balancing traffic as what I’ve done with MLPPP / IPCef on Cisco.

Core is Juniper M series & Catalyst 2924XL.
Though only for Incoming direction on switch, it realy does help much overcoming overloading traffic 100 Mbps on one port from two ports aggregation.

Thanks to Arif Juniper, Iwibisana & Jamalul Izza for config and idea.
All wrapped now.
Next to think : Outgoing Load Balance.

Juniper MSeries Configuration.

interfaces {
fe-0/2/0 {
fastether-options {
802.3ad ae1;
}
}
fe-0/2/1 {
fastether-options {
802.3ad ae1;
}
}
