PC5448, VLAN, and Linux Channel bonding

Hi,

 

I'm in trouble configuring a Linux server with a PC5448 switch :

- switchports 45-48 are trunked to my backbone (10 VLANs)

- switch ports 1,2 are members port port-channel 2

- port-channel 2 is in access mode on VLAN 9

- the server have 2 Gb NICs (Intel) connected to switch ports 1,2

- I created a bonding interface on the Linux server using 802.3ad mode

 

But when I assign an IP to that interface and try to ping other hosts on my VLAN 9, I get nothing. The switch itself seems to be blind !

I have to precise I tried to put switchport 3 on access mode for VLAN 9 and it works fine. I guess the problem is with the port aggregation, but don't know why.

 

Thanks for any suggestion
