I've just had to setup a SFW cluster to host a NetBackup Master server for a customer with a complex environment.

They have 20 backup VLAN's. Its not that many, but enough to cause a problem.

Their Master server nodes are connected to a dedicated backup network using a pair of LACP bonded 10 GbE NICS. We created 20 vNICs to support the VLANs (using the miniport driver supplied by the NIC vendor)

When I came to configure the backup IP resources I found a problem in that the IP agent requires that the IP's it monitors have the MAC address of the NIC they are bound too.

All 3 teaming software packages I tried(intel/Broadcom/Emulex) did not allow MAC spoofing and so when adding the 20 Virtual IP's they decided to all bind to 1 vNIC, and obviously only 1 IP address worked (only 1 IP was on the correct VLAN).I got round this by using a netsh script to add and remove the IP's as part of the online/offline process, but they are not monitored by VCS.

I would like to see VCS for windows built in agent for windows support the ability to bind an IP address to a card name as an option (as it is on the *nixes eg "bond0.1234"). I cant imaging its a lot to ask, this functionality has been built into windows since 2003.

(netsh interface ip add address name="interface name" ipaddress subnetmask)
(netsh interface ip delete address name="interface name" ipaddress)

Thanks

Hi @toady777, I heard back from the product management team, and they recommended going through the official process of working with your account team for something like this exception.

Thanks for your suggestion!

Best,

Kimberley
