No it doesn't, you won't be able to log on.  For this reason you should always configure Console access as Local as a safety net / fall back should TACACS fail.  THen at least you can console in, change the auth to Local and use local accounts. So in effect, you have to "manually fall back to local" - it isn't automatic. Cheers Steve ... View more

Hey Simon, let's address this is two parts because there are two layers: server-bound (ESX-6120) and north-bound (6120-Cat4900). At the ESX end, use the default srcPort in the vSwitch / port group with both 10GbE uplink ports (vmnic0 and vmnic1) set to active (not active/passive).  There are no loops in this configuration.  On the VNIC (in UCSM) you select trunk port and allow all the VLANs that your vSwitch port groups needs.  If you don't use a VLAN for the Service Console/ESXi Management, then make sure you set Native to the correct VLAN in the VNIC to allow untagged traffic down the right path. At the 6120 you can't explicitly configure a trunk for border ports, they are already set so and when you add VLANs they are added to every border port trunk configuration.  You, of course, need to make sure the Cat4900 ports at the other end of the cable have the same trunkport VLAN configuration. So in summary - set VLANs in vSwitch port groups, VNIC in UCSM and northbound switch.  Now when it comes to port channels, you can only configure two or more border ports as a port channel if they are cabled to the same Cat4900.  If you had Nexus 5k/7k northbound then you could use vPC on them to allow "mesh" cabling (ie. one 6120 connects to both Nexus switches).  But as you aren't using Nexus you will end up with a configuration as Jeremy explained: ESX --> vSwitch0 --> srcPort load balancing --> 2 active uplinks --> many port groups 6120-a --> Cat4900-a 6120-b --> Cat4900-b However, I would still recommend using a couple of border ports in a port channel on each fabric to each Cat4900 because, if you pull out a cable/lose a port, then when that port is re-enabled the existing live traffic is redistributed whereas without the port channel only new traffic will be spread across both links.

Hey Jason, great to see you on here :-) We don't set a Hostname value but we do set a UUID which is what other enterprise tools use to uniquely identify that blade - Microsoft System Center and Altiris being examples off the top of my head. HTH Steve ... View more
