Filling in for an Engineer and i need to config a LACP, could anyone tell me if this is correct before i throw it into production? One question i do have, do i have to assign the channel an IP? Also will the LACP system-priority configure to default?

Ether channel is 53
interfaces to team are g2/0/4-5
active for aggregate

thanks in advance

MDF-sw4c2> en
MDF-sw4c2# conf t
MDF-sw4c2(config)# int port-channel 53
MDF-sw4c2(config-if)# ip address 10.25.20.33
MDF-sw4c2(config-if)# int g2/0/4
MDF-sw4c2(config-if)# no ip address
MDF-sw4c2(config-if)# channel-group 53 mode active
MDF-sw4c2(config-if)# exit
MDF-sw4c2(config)# int g2/0/5
MDF-sw4c2(config-if)# no ip address
MDF-sw4c2(config-if)# channel-group 53 mode active
MDF-sw4c2(config-if)# end

Looks allright. Might have to do no switchport on the port-channel 53 interface also, depending on the device.

might need "no switchport" too, depending on the hardware

edit: just noticed your question. do you need an L3 channel? if not, then no, you don't need an IP and shouldn't assign one.

You do not have to assign the port-channel interface an IP. Also... Do you plan on having the port-channel trunk VLANs or only access 1 VLAN? The important thing to remember is to keep the interface configurations identical.

so the int wont keep the vlan config? the will only access on vlan, but not the default


thanks for everyones comments

Not sure what you are asking... Depending on how the interface is setup, it can be for a single VLAN or multiple VLANs as a trunk. If you did nothing else to the ports, in that configuration you posted it will either be an access port in VLAN 1 or if the other side is set up to actively attempt to trunk, it will trunk all VLANs.

You've create a L3 LACP port. The config is perfectly fine if you wanted an L3 port to begin with.

If not, you need to add switchport to both the po interface and the individual interfaces. If you do this you may need to re-add the interfaces to the po as in the interim one will be L2 while the other L3

Right I dont mean to confuse things... He asked if an IP was necessary so I was just giving my .02

wait until the engineer gets back

I wish, he's gone for good.

Infact both of them are as of last wednesday.

I think its better you explain what you're trying to accomplish, then we'll be able to help you with the conf

Go on the other side of the link , du a "sh run | b port" a "sh run int (int in question) " sh int trunk" and finaly a "sh ether sum and sh ether detail" copy the config and paste it on the L3 switch in question. See if you really need an ip address under the portchannel. If you don't it should work anyways. I guess :p
Also you should start some debugging before you paste anything : debug etherchannel [all | detail | error | event | idb ]
I would also make a notepad with those commands and a NO in front of them. If something fails (you will know because of the debug output) you can undo them quickly. If you can spare the time : http://www.cisco.com/en/US/docs/ios/12_ ... elacp.html

And on the other side, doesnt he have to configure as "passive" and not active on both sides? I forget if that even works. Ive always done passive on one side (downstream) and active on the upstream side (like a core switch) for LACP. Right/Wrong?

Active on both sides is fine. Passive on both sides is a problem.

active just means that both sites will actively negotiate the link protocol.

Got it. Hmm, I wonder whats the practical reason behind choosing active/active vs active/passive then?

so here is what is on the switch already...


interface Port-channel57

switchport
switchport mode access
no ip address

interface Port-channel58

I need another team for link aggregate for another SQL cluster.

here is what i tried to configure on a 6509 but get error on the channel group command


interface Port-channel49
description MCKTORCSQL03a NIC TEAM
switchport
switchport mode access
no ip address
channel group 49 mode active

mn i'm not intelligent, mode active is only on the interfaces

ok, so it seems as if you're using switchports in vlan 1. The channel-group command goes on the physical interfaces that makes up the port-channel.. so:



Ah missed your last post . Got it to work?
