Use Microsoft Network Load Balancing (NLB) to share the workload among multiple clustering servers. For information about software scaling capabilities, see VOSS Release Notes.
For all modes, configure an IP address on the VLAN enabled with NLB.
To switch between Unicast NLB and Multicast NLB, you must first disable the NLB support.
Use the following procedure to configure NLB support on an IP interface to enable or disable NLB support.
The default value is NLB support disabled.
Note
SPBM supports Network Load Balancing (NLB) Unicast and Multicast modes.
enable
configure terminal
interface vlan <1–4059>
nlb-mode unicast
Or,
nlb-mode multicast
To switch from one nlb-mode to another, you must first disable the NLB support, and then enter the new nlb-mode.
no nlb-mode
Configure unicast mode for VLAN 2, and then switch to multicast mode.
Switch:1(config)#interface vlan 2 Switch:1(config-if)#nlb-mode unicast Switch:1(config-if)#no nlb-mode Switch:1(config-if)#nlb-mode multicast
