I’m just tracing some troubles I’m having with a backup server and two (independent) network adapter ports (as in two ports on two different dual-port nics). If I enable the port and set it to auto configuration, it’ll get 100MBit/Half-Duplex, but the Portgroup becomes unavailable.
In order to get the connection back, I need to logon on the console (thank god even the backup server got an iLO2), and manually (as in esxcfg-nics -s 1000 -d full vmnic1) configure the adapter to 1GBit/s and full-duplex.
Since I didn’t want to go downstairs and trace the damn cables, I figured I could use the CDP features included in ESX. Turn the NICs on as 100MBit/Half-Duplex and run:
|
1 2 3 4 |
vmware-vim-cmd hostsvc/net/query_networkhint --pnic-names=vmnic1 | egrep "(address|portId)" address = "10.0.0.35", portId = "GigabitEthernet0/28", |
That’s all the networking guys should need. Switch’s IP-address and the Switch Port where the card is connected to. *Tada*.
Update: with ESXi 5.1, it’s just vim-cmd …
