Problem with LACP on 4500g switches

[muralla]

Hi all,

I have install the new firmware 5.02.00s168p02 in my 4500g switches.

Now LACP doesnt works... Can anyone explain me the form to configure LACP or aggregatted links with this new firmware?

Thanks

Hi Muralla.



On trunk ports the PVID is necessary, since you use another interface VLAN to manage the switch instead the VLAN 1 (default VLAN). If you use the VLAN 1 with your management IP address, don't issue the command "undo port trunk permit vlan 1". The PVID is necessary, because you don't need to tag the local VLAN; that´s why you don't need to setup a PVID when using the default VLAN as the management VLAN.



On access ports you just need to tell the switch which is the VLAN assigned to that port - actually the VLAN you assign it will be the PVID of this port.



These settings are only local significant, and will work with any other switch with LACP enabled on the ther side, even from another vendor.

Hi, Muralla.



The new firmware that you installed supports link-aggregation but with a different way to implement. You need to create an "interface bridge-aggregation" first, configure this interface as the ports that belongs to the link-aggregtion and configure the ports also. Example (regarding the port in trunk mode):

-----------------------------------------

interface bridge-aggregation

port link-type trunk

port trunk permit vlan

port trunk pvid vlan



interface giga 1/0/1

port link-type trunk

port trunk permit vlan

port trunk pvid vlan

port link-aggregation group



interface giga 1/0/2

port link-type trunk

port trunk permit vlan

port trunk pvid vlan

port link-aggregation group

-----------------------------------------



You need to create the interface bridge-aggregation before setup the ports; the ports configuration needs to be exactly the same on all ports that belongs to the same link-aggregation group.



Hope this helps.

Fred thanks a lot¡¡¡ Tomorrow i go to try your answer.



First i have more questions ¡¡



1)interface bridge-aggregation= group??

2)port trunk pvid vlan -->What is pvid

3)port link-aggregation group is the same id of interface bridge-aggregation?



And last question... This agregatted links, works if the other switch works withc LACP?



Thanks¡¡¡



In my case i need 2 agregatted links.

1-->port 1 and port 25 (trunk permit vlan 5 and 6)

2-->port 49 and port 50 (acces, permit vlan 4)

Hi.



1)interface bridge-aggregation= group??



No. You just need to create a virtual interface, that is the interface bridge-aggregation with an ID. You can choose one ID among the several IDs supported by your switch. Choose the ID 1 for the first and ID 2 for the second aggregation-link.



2)port trunk pvid vlan -->What is pvid



PVID = Private VLAN ID. It's the VLAN that you want to maintain untagged through the trunk.



3)port link-aggregation group is the same id of interface bridge-aggregation?



Yes.



In my case i need 2 agregatted links.

1-->port 1 and port 25 (trunk permit vlan 5 and 6)



interface bridge-aggregation 1

port link-type trunk

port trunk permit vlan 5 6

undo port trunk permit vlan 1

port trunk pvid vlan



interface giga 1/0/1

port trunk permit vlan 5 6

undo port trunk permit vlan 1

port trunk pvid vlan

port link-aggregation group 1

interface giga 1/0/25

port trunk permit vlan 5 6

undo port trunk permit vlan 1

port trunk pvid vlan

port link-aggregation group 1



2-->port 49 and port 50 (acces, permit vlan 4)



interface bridge-aggregation 2

port link-type access

port access vlan 4



interface giga1/0/49

port link-type access

port access vlan 4

port link-aggregation group 2



interface giga1/0/50

port link-type access

port access vlan 4

port link-aggregation group 2



To check the link-aggregation status, use the command:



display link-aggregation verbose
