Regarding LACP commands on Cisco 6509 to connect server

[satishmothukri]

Hi All ,

We have to connect two servers to cisco 6509 (sup720 with MFFC R7000)  switches and we have to configure LACP on the 6509 to bundle two ports to get 2 Gbps through put.

Each server has four NIC ports ..out of which two ports will be connected to Switch 1 ( active ) and remaning two ports will be connected to switch 2 ( standby).

We are going to use below commands for LACP on both the switches.Apart from below commands do we need to have any other commands to make LACP to work as soon as we connect the servers.

Switch 1 :

set channelprotocol lacp 1

set port lacp-channel 1/1-2 73

set port lacp-channel 1/1-2 mode active

Set port vlan 10 1/1-2

set spantree bpdu-guard 1/1-2 enable

set port lacp-channel 1/9-10 85

set port lacp-channel 1/9-10 mode active

Set port vlan 10 1/9-10

set spantree bpdu-guard 6/9-10 enable

On the MFFC we have so many vlans along with vlan 10

int Vlan 10

ip address 10.10.10.2 255.255.255.0

standby 10 ip address 10.10.10.1

standby 10 timers 1 3

standby 10 priority 200

same series of port will be used on Switch 2 to connect servers.

Servers support LACP protocol only.

diagram is enclosed...If any suggetions on this would be appreciated..

Thanks ,

Your 6509 switches use CatOS?

Interesting I thought all sup 720's were non hybrid and used IOS only .  Guess you learn something everyday. Looks like it should work with what you

have as long as the servers are setup with lacp in a active/standby mode.
