Now it works ¡¡¡¡

I have make the parameter ip routing and now it works fine.... ¡¡¡

Please help.

With ip routing it works but, if i create a LAG in mode auto (LACP) it not works.

The LAG its etablished in the m6220 and a 3com 5500 but the routing not works.

Example-->

If i link the 2 switches using one port  ,it works.

If i link the 2 switches using LAG with lacp, the LAG its etablished but the traffic works only in the Out of band interface...I have included the channel group 1 in the vlan 100.

I have one vlan 100 interface 10.0.4.7 and a default gateway 10.0.4.1. and the OOB interface 10.0.5.3 and the gateway 10.0.5.1

Example with LAG etablished(it goes to the OOB interface)

SW-CC-RG-17#traceroute 10.0.4.6
 Traceroute to 10.0.4.6 ,30 hops max 0 byte packets:
1  10.0.5.1           <1  ms    <1  ms    10  ms
2  10.0.4.6           <1  ms    10  ms    <1  ms

Example without LAG etablished

SW-CC-RG-17#traceroute 10.0.4.6
 Traceroute to 10.0.4.6 ,30 hops max 0 byte packets:
1  10.0.4.6          <1  ms    <1  ms    10  ms

Why with LAG the vlan interface 10.0.4.6 no routing and all the traffic goes to the OOB interface¿?¿?¿?

Please, can anyone help me??

Regards.

Please post you r current config and more information about the behaviour you are seeing with that config.

Tomorrow i go to post a part of the config.

Basically the problem is that:

When one interface ethernet (switch port acces vlan 100) conects with another switch it works fine.The ping to the vlan interface 100(10.0.4.7) of m6200 works.

When i create a LAG with some interfaces, and the channel group in the vlan 100 i cant ping the interface vlan 100.The LAG its etablished but the ping not works.

Why with LAG the routing not works and without him the routing works???

Regards ¡¡¡

Ok, this is the config

!Current Configuration:

exit

!
interface port-channel 2
switchport access vlan 100-------->Portchannel 2 member of vlan 100

In this escenario you can view 2 interfaces in a chanel group.

If the LAG its etablished with the other switch i can´t ping te interface 10.0.4.7.
If one interface (1/g17 or 2/g18)its not in the channel group i can ping the interface 10.0.4.7

Why i can't ping the 10.0.4.7 when the LAG its etablished ¿? Please help.

Ok, i have disabled stp and now it works.

This is a bug of powerconnect??? I can't use LAG and stp in the switch'?

Regards

PowerConnect switches (and most standards based switches) run a single instance spanning tree by default.   This means the spanning tree is determined regardless of vlan configuration.   This can result in interfaces being blocked because a physical loop exists, even thought a logical loop does not exist if the administrator does not take the single instance spanning-tree into account.

yes it is possible to have STP enabled and use LAGS. 

"does not take the single instance spanning-tree into account".

What is "account". Its posible enable stp or not in m6220 using LAG¿¿?

My friend. Im spanish i speak very bad english.

Can you explain me how to can enable STP and LAG in powerconnect m6220¿?
