HP DL 380 G5 - SLB

[hpabc]

Hi,

We have 2 NICs on HP DL 380 G5 server running Win2K3-R2. I want to configure SLB for same. Drivers are updated to the latest.

I connected both the NIC to Cisco 3560G-L3 switch. I selected the SLB option in the HP Network conf utility with all defaults.

Switch is configured as below for both ports,
config t
interface range 0/19 - 20
no ip address
no switchport
channel-group 10 mode on
end

config t
port-channel load-balance src-dst-ip
end

I am not able to connect to the server. Ping does not work.

Please guide what could be the cause and troubleshoot.

Thanks,

Sid.

Hi SId

While enabling the SLB in the Network Configuration utility you can enable the SLB either using the layer 2 or layer 3. try enabling the layer 2 that is instead of ip address configure load balancing using the mac address on both sides and check.

Hi,

I tried to configure it as below,

config t
port-channel load-balance src-dst-mac
end

config t
interface range gig 0/19 - 20
switchport
switchport mode access
channel-group 10 mode on

At the channet-group command i get the error as -

Command rejected (Port-channel10, Gi0/19): Either port is L2 and port-channel is
L3, or vice-versa

% Range command terminated because it failed on GigabitEthernet0/19

Please guide

Thanks,

Sid.

Hi

I skipped to add the vlan on that ports. After adding the ports to vlan, i am able to communicate with the server !!! :P

But i am not able to set the channel-group option.
I can configure channel-group only with "no switchport" option. With that command i am not able to add the port in its vlan.

The configuration now is as below

interface range 0/19 - 20
switchport access vlan 101
switchport mode access

Please guide.

Thanks,

Sid.

Hi,

The problem is resolved. The channel-group 10 was L3. Creating a new channel-group 20, L2, resolved it. The configuration now is -

config t
port-channel load-balance src-dst-ip
end

config t
interface range gig 0/19 - 20
no ip address
switchport mode access
switchport access vlan 101
channel-group 20 mode on
end

Thanks

Sid.
