Re your FEX to FI Uplinks, as far as I know there is no recomendation as how to connect the ports of a 2208 (I generally just connect them top down) It that because of trunk configured for interfaces Thank you !! This might get the problem fixed but this will also disrupt the traffic that is passing through this HBA, so I would advise to restart the blade to get it cleared. See ya around!
I am seeing this error on Chassis-1 at all for all 8 blades-Amit See More 1 2 3 4 5 Overall Rating: 0 (0 ratings) Log in or register to post Use the same IP and login details as you use to login to UCSM. The FI server ports are listed in the second column “Fabric Port”. The VMs inside the ESXi host installed in the blade did NOTsuffer any impact.
subsequently, not able to ping from a physical host outside of UCS to a server within UCS ? This is how the VIC can provide hardware fabric failover and fabric load balancing to its virtual interfaces.These adapter ports are listed as 1/1 to Fabric A and 2/2 to Fabric Cisco UCS Generation 3 FirstLook.

Fex Host port In the lab setup I am using, the FEX modules are 2104XP’s which have 8 internal Server facing ports (Sometimes referred to as Host Interfaces (HIFs)),which connect to Ucs Vif Path Non Participating The only obvious thing to point out is that there is no direct connectivity between the A and B fabric inside the UCS system, so these DHCP requests have to go It is then up to the vSwitch on the host to decide how to balance the VMs over these two uplinks. I can see the port map from the VM to the Veth on the 1K but not going north towards the FI's .
Gen 2 FEX's as you know have multiple HIFs per slot, the 2204XP has 2 HIFs per Blade and the 2208XP which has 4 HIFs per blade.

Cisco Ucs Vif Paths Also I cannot see "sho pinn" command in nxos mode of this version. Ucs Backplane Port Link Down I believe they are the FEX-host ports, the internal facing ports that connect to the blade servers.
Keep in mind that it is a bit hard for me to judge this without seeing your actual setup, but this might explain the behavior you are seeing. Instead of rehashing the basic principles of fabric failover, I intend to dive a bit deeper into the UCSM GUI, UCSM CLI and NX-OS CLI to examine and illustrate the operation So in the example you mention a B250 in slot 1 of Chassis 2, will have 2 possible bound eths 2/1/1 and 2/1/2 each meaning a differen Mez Card.

Welcome to IT Blog!Thanks for dropping by! In this post I do not intend to cover the basics of Fabric Failover, as this has already been done excellently by other bloggers. That is the objective of this post. Using the UCSM GUI we can find them in the "VIF Paths" tab: As you can see vNIC eth0 is associated with two virtual Ethernet interfaces: veth 703 on fabric A
