Brocade Network OS Administrator’s Guide v4.1.1 - Manual (Page 254)

An invalid state or condition of a vCenter can cause the deletion of all auto-port-profiles in a system.
To prevent this from happening, configure the ignore-delete-all-response operand of the vcenter
command to ignore the “delete-all” responses from the vCenter.
switch# vcenter MYVC discover ignore-delete-all-response 5
Activating the vCenter
After adding the vCenter, you must activate the configured vCenter instance.
NOTE
In VCS mode, you can configure the vCenter by using any node. Discovery is initiated by the primary
node.
1. Enter the config command.
2. Enter the vcenter command to activate the vCenter.
switch(config)# vcenter myvcenter activate
Immediately following first-time vCenter activation, the Network OS starts the virtual asset discovery
process. Use the show vnetwork vcenter status command to display the vnetwork status, as in
the following example.
switch# show vnetwork vcenter status
vCenter Start Elapsed (sec) Status
================ ==================== ================ =============
myvcenter 2011-09-07 14:08:42 10 In progress
When the discovery process completes, the status displays as "Success." Network OS has
performed all the necessary configurations needed for the vCenter Server, and is now ready for
CDP transmissions from the virtual switches to identify which ESX/ESXi host is connected to which
physical interface in the Ethernet Fabric.
Discovery timer interval
By default, Network OS queries the vCenter updates every thirty minutes. If any virtual assets are
modified (for example, adding or deleting virtual machines (VMs), or changing VLANs), Network OS
detects those changes and automatically reconfigures the Ethernet Fabric during the next periodic
rediscovery attempt.
Use the vcenter interval command to manually change the default timer interval value to suit the
individual environment needs.
switch(config)# vcenter myvcenter interval ?
Possible completions:
Timer Interval in Minutes (default = 30)
NOTE
Best practice is to keep the discovery timer interval value at the default (30). A value of 0 disables the
periodic vCenter discovery.
User-triggered vCenter discovery
The discovery of virtual assets from the vCenter occurs during one of the following circumstances:
