N5K, FEX, vPC and XenServer - Painful!

djensen · ‎12-26-2013

Hardware

* 2x 5548UPs in vPC domain (v6.0.2)

* 2x FEX units

* 2x XenServer 6.1

* 2x 10GB NICs bound using active-active LACP per XenServer

Scenario

* Attempting to connect XenServer to N5Ks

* Dual homed FEX design

* Utilizing enhanced vPC to dual-homed XenServers

* Can establish vPC between peers and down to FEX units

* Port-channels are all in the "UP" position

* Cannot ping Xenserver management IP

* XenServer management requires non-trunking port and a native vlan

* On other Cisco switches I would define a native vlan and tag the other vlans coming from the hypervisor. Therefore...

* Enabled 802.1q native vlan support in N5K (vlan dot1q tag native)

* Attempted to make vlan 1 as the "native vlan" but it does not show in the port-channel interfaces

* Created new vlan and made it the native vlan but still could not ping XenServer management IP.

* "show vpc" displays the vPC peers with the "active vlans" I defined in the config

* "show vpc" displays the vPC to the FEX but NO "active vlans" are present

* "show vpc" displays the port-channels as up but the only "active vlan" is vlan 1.

My question, I suppose, is whether anyone has configured XenServer to a pair of N5Ks using vPC and successfully connected/pinged the management interface?

djensen · ‎12-27-2013

UPDATE

I have made some progress but very little. Basically, I have blocked all physical ports that could possibly access this blade server except for those ports connecting directly to the dual FEX units. Just after XenServer finishes booting there is a window of time where I can ping the management IP (10.1.1.59 - native vlan) from both Nexus switches. After ~1min I can no longer ping the IP. However, if I source the ping from my loopback IP address I get a response. In other words:

* I can ping the XenServer management IP right after bootup.

* After a minute (or so) I can no longer ping the IP.

* I can ping if I use the cmd, ping x.x.x.x source loopback 0 IP address (192.168.72.253)

* Loopback 0 is in a "peering-vlan" and not in VLAN 1 (native vlan).

Any thoughts? Anyone?

Thanks,

David

Can you please paste show run from the nexus switches?

djensen · ‎12-27-2013

Here are the two configs. Pretty simple and straight forward as I have yet to complete the setup.

edondurguti · ‎12-27-2013

Sorry maybe this is pretty basic question, do you use ping x.x.x.x vrf management when you ping the xen servers?

What's the ip you're trying to ping?

do a traceroute to that ip.

djensen · ‎12-27-2013

I have done the following:

* ping 10.1.1.59 - only responds within the first minute or so after XenServer boots up. After that it doesn't respond.

I assume these are ports where XenServer is connected?

Can you post show interface trunk

interface Ethernet130/1/9
description Connected to Blade 9
switchport trunk allowed vlan 1,71-75,97-99
channel-group 109

interface Ethernet130/1/10
description Connected to Blade 10
switchport trunk allowed vlan 1,71-75,97-99,101
channel-group 110

interface Ethernet130/1/11
description Connected to Blade 11
switchport mode trunk
switchport trunk allowed vlan 1,71-75,97-99
channel-group 111

interface Ethernet130/1/12
description Connected to Blade 12
switchport mode trunk
switchport trunk allowed vlan 1,71-75,97-99
channel-group 112

interface Ethernet130/1/13

interface Ethernet130/1/14

That is correct. However, we should only be concerned with 120/1/9 & 130/1/9. The other blades haven't even been turned on. Here is the output:
