[c-nsp] Cisco 6509 LACP

[Mike Glass]

Ok , I had ip address on my vlans on the 6509, I put the corresponding
ip addresses on the force10 and can ping everything in those vlans fine,
and can ping the addresses from the 6509.
 
So wonder if it is a configuration on the vmware side or the force10
side, dell set it up to work as planned but not to sure now. 
 
 
Thanks again
 
Mike

Hi Mike,

You can configure one unassigned IP address to each switch's "interface
Vlan x", and check if they can ping each other when using a
port-channel. This should not cause any harm if you use an unassigned
IP. The configured IP then can be used for testing between the force10
and vmware, by doing a direct ping test between them, then between the
6500 and the vmware.

Best regards,
Andras

The Dell switch does has not have cdp, just lldp, on the cisco switch I
see nothing in cdp for the interfaces, the dell lldp I do see the vmware
interfaces.
I have switched to mode active with same results.
I have not configured address on the vlans, not sure if that will break
anything in our existing system, If I do put ip address on a vlan on our
production system will it cause any problems?
The force 10 vlans are tagged for vlans 4 and 2
interface Vlan 4
no ip address
tagged Port-channel 1-2
no shutdown
when I shut the port-channel off on either switch I see messages on
both switches that eh protocol is down, so I think I am close but still
cannot pass traffic from the a vm guest.
I also wonder if I already have the Vmware server hooked up to the 6509
on another interface that uses the same vlan could be causing some
problems.
Thanks
Mike

Hi Mike,

First of all, how do you see that traffic is not passing? Could you
please elaborate on how do you test it, from where to where are you
trying to send traffic or ping tests? Does traffic pass if links are
used as standalone (not being in a channel)?

If you configure an IP address for each vlan interface, can you ping
between the 6500 and the force10? If yes, the problem might be between
the vmware and force10 instead.

Are the force10 ports configured for dot1q trunk as well to be able to
carry multiple vlans? Are they set with the same native vlan as the
Cisco? (Default native vlan is 1)

Could you do a sh spanning-tree on both switches for the po interfaces
to make sure they are not blocking? sh span int po1

Do you see the correct neighbors in cdp table? sh cdp nei

Can you confirm that the same issue is observed when using 'mode
active'?

Best regards,
Andras
