Connecting 2x 3560 and configuring LACP - Advice?

[jason.webb87]

Hi Guys,

I have been asked to setup some new switches in our LAN.

We have 2x WS-C3560X-48 with the 10Gb SFP C3KX-NM-10G module.

I want to use the 10Gb SFP (with a redundant 1Gb link) between each of the switches.

Below is the configuration what I think I should use. Is this correct?

SWITCH1

int TE1/1

switchport trunk encapsulation dot1q

switchport mode trunk

channel-group 1 mode active

int Gi0/48

switchport trunk encapsulation dot1q

switchport mode trunk

channel-group 1 mode active

SWITCH2

int TE1/1

switchport trunk encapsulation dot1q

switchport mode trunk

channel-group 1 mode active

int Gi0/48

switchport trunk encapsulation dot1q

switchport mode trunk

channel-group 1 mode active

We also want to utilise Link Agrrigation for the servers that attach to the switch. Would this config be correct?

port-channel load-balance src-ip

int range x

switchport mode access

switchport access vlan 1 (They are all on the default vlan)

spanning-tree portfast

channel-group x mode active

(Then I would configure the LACP config on the server)

Is there anything I am missing? I would like this to go as smooth as possible.

Any help is appreciated

Won't work.

Rule #1 in Etherchannel.  ALL the links need to have the SAME SPEED. 

[jason.webb87]

Ok Thanks,

So if I remove the Etherchannel on the links between the switches like so. This will work?

SWITCH1

int TE1/1

switchport trunk encapsulation dot1q

switchport mode trunk

SWITCH2

int TE1/1

switchport trunk encapsulation dot1q

switchport mode trunk

Yes, this will work fine.

FYI and as Leo noted:

When deploying portchannel, the ports on both sides need to have the same speed and duplex.

Thank you Leo and Reza for your help. This answers my question.

Your second question, LACP.

My opinion is to use "ON" instead of "ACTIVE". 

[jason.webb87]

Thanks, I'll give that a try.

Is there anyway to setup a redundant 1Gb connection between the switches, incase the 10gb module fails?

Preferebly a solution that supports automatic failover?

[Leo Laohoo]

Just put two 1 Gbps in an EtherChannel.

If you have only 1 x 10gb port between the 2 switches and you want to use this and have a backup using a 1gb, why not just have both in a RSTP trunk?

Hi Andy,

How would I go about creating a RSTP trunk with Gi0/48 and TE1/1 bewteen each switch?
