I would like to create a failover bonding between a 10 GB NIC and an aggreation of 4 x 1 GB NICs
Is it possible ? Is there any other solution than bonding ?
thanks in advance for your help
For bonding, the 802.3ad mode with ad_select=bandwidth should do this.
First of all, thanks for your reply !
You think I can build a bonding interface with the 5 links and this options ?
On the switchside, I will have to create an LACP group with different link speed, I thought it was not allowed …
On the switch, you would create two LACP groups: one for the 10G, and one for 1G. The linux bonding 802.3ad will associate those into two separate aggregators (putting all five interfaces into one bond), and select the "better" aggregator according to the criteria selected by the ad_select option (where "bandwidth" I think will do what you want).
Oh great, I'll try that tomorrow and post the result
thanks again for your help !
Unofrtunatly, I am using a RH 5.8, and so the 3.4.0 version of bonding driver which does not provide the "ad_select" option (appeared in v3.5.0) … So actualy the bonding driver is choosing the most secure aggregate : 4 x 1G ….
