Hi. I'm still working on this since I haven't touched it in a while. I still have the critical alerts since I wanted to get to the bottom of this before acknowledging them. Traffic seems to be working fine, despite the alerts persisting.
There are 2 physical switches going to the vDS: HP ProCurve --> Flex-10 pair switch --> vDS
The ProCurve pair is trunking 3 Vlans to the Flex-10s:
2 ports in a trunk (x2, 4 total, 2 per switch)
Vlan 100 Untagged
Vlan 200 Tagged
Lan 300 Tagged
The Flex-10s configuration shows the same:
6 nics per host x 5 hosts (30 uplinks to vDS)
Vlan 100 (Native)
Vlan 200
Vlan 300
vDS:
dvUplink Group 1 (6 links x 5 hosts = 30 total)
Port Group A (Vlan ID = 0)
Port Group B (Vlan ID = 0)
Port Group C (Vlan ID = 0)
These links from the Flex-10s are all trunked to a single dvUplink group on the vDS, and then there are a few vDistributed Port Groups and each of those have no Vlan ID assigned, as mentioned (so, Vlan ID = 0)
For some reason, all 5 of the hosts appear to be configured the same but only one of them now shows no critical alerts. I don't recall acknowledging the alerts.
I'm thinking of testing out just assigning the matching Vlan IDs to the Port Groups as recommended, but I'd like more info before I break something.
I read at the link below that if tagging is done on the physical switch, the Port Groups' Vlan ID on the Virtual Switch should be zero, but I'm not sure if this applies here or if they mean in a situation where the vDS is connecting to an ACCESS port in a Vlan on the physical switch, or something else. Any clarification or additional help would be great, based on the detail I've added. Thanks.
