m1000e no traffic between A2 and blades with esxi

Hi,

I didn't real difference between these logs except the point :

For A2 :  This Switch is the Root.
For A1 : Root Port Po1 / Designated path cost: 2004 (0 for A2)

At this step, as Josh mention, this problem seems to be more related to a Vswitch configuration issue than a pure hardware issue. Have you tried to reboot the switch and/or swap the blade?

Regards,

Hey Stephane,

For the physical switch, we've rebooted, and also swapped it with a spare.

For the blades, we've tried different blades, some running different instances of esxi, and therefor different vswitches. all the same issue still.

I would start by verifying the blade NIC can communicate to the switch.  On your test blade, make sure the only active uplink is the one mapped to switch A2.  Take a VLAN that is on both the ESXi host and the Switch, and work with that:  On the switch, if there isn't one already, put an IP address on that VLAN (I think the 6220 is a L3 switch, I can't remember).  At that point try to ping the VLAN IP (SVI) from the blade.  So just a simple layer-2 check here.  You will be able to see the MAC address in the output of "show mac address-table" if this is working.  Once you get that working, you can move on to troubleshoot upstream connectivity.

The Teaming policy is set to "Route Based on Originating port ID" for both the port group and the vswitch.

Here's the mac address-table, surprisingly small. Only shows it's own interface for vlan1.

the A2 uplinks to a Cisco C9500. originally it was port channeled, but we removed it during the trouble shooting process, so it is just a single link running at 10g. config is simple for both sides:

A2:

interface Te1/1/1
duplex full
channel-group 1 mode active
spanning-tree disable
switchport mode trunk
switchport trunk allowed vlan 1,1101
exit

Cisco

interface TenGigabitEthernet1/0/30
description Rack 8 DellBladeChassis fabric A2
switchport trunk allowed vlan 1,1101
switchport mode trunk
no cdp enable
channel-protocol lacp
channel-group 30 mode active
end

I added in the channel-protocol LACP at one point during troubleshooting, it needs to be removed.

I went and tooka slightly different angle for your suggestion first, verifying the connectivity between my c9500 and the m6220. I've just realised i've been using an OOB interface this whole time for my connectivity.

both the 9500 and m6220 are using vlan 909, with an IP on the SVI each. I'm not able to reach the 6220 on that SVI.

Here is the full output to their connections:

m6220:

interface Te1/1/1
duplex full
channel-group 1 mode active
spanning-tree disable
switchport mode trunk
switchport trunk allowed vlan 1,1101
exit
!

as an addendum to my previous post. It looks like the CMC interface handles the OOB interfaces for the connected switches. I found this by Looking at the ARP entry for the IP i've been using  for it, and tracing the MAC. 

I've noticed when I turn off the links to the A2 on the 9500, I also lose connection to the OOB interface, even though they should be unrelated.

As it looks like there are several issues with this dell switch, I'm isolating each one and trying to find a root cause.

Right now, I've identified that I'm not able to see layer 2 between my cisco 9500 and the dell m6220. I've simplified the config between them. I'm not able to ping the vlan 909 interface on the dell switch for some reason.

Here is there config:

Great to hear, let us know if you need anything else.
