53-4 create nlb multicast_fdb
Description
This command is used to create a NLB multicast FDB entry. The number of supported entries is
project dependent.
The network load balancing command set is used to support the Microsoft server load balancing
application where multiple servers can share the same IP address and MAC address. The
requests from clients will be forwarded to all servers, but will only be processed by one of them.
The server can work in two different modes – unicast mode and multicast mode. In unicast mode,
the client use unicast MAC address as the destination MAC to reach the server. In multicast mode,
the client use the multicast MAC address as the destination MAC to reach the server. Regarding of
the mode, this destination Mac is the named the shared MAC. The server uses its own MAC
address (rather than the shared MAC) as the source MAC address of the reply packet.
The NLB multicast FDB entry will be mutual exclusive with the L2 multicast entry.
Format
create nlb multicast_fdb [<vlan_name 32> | vlanid <vlanid 1-4094>] <macaddr>
Parameters
multicast_fdb - Specify the VLAN of the NLB multicast FDB entry to be created.
<vlan_name 32> - Enter the VLAN name here. The VLAN name can be up to 32 characters
long.
vlanid - Specify the VLAN by the VLAN ID.
<vlanid 1-4094> - Enter the VLAN ID here.
<macaddr> - Enter the MAC address of the NLB multicast FDB entry to be created. Multicast
MAC addresses with the prefix of 33-33-XX-XX-XX is used for address mapping with IP
addresses. To avoid incorrect forwarding behaviors, 33-33-XX-XX-XX is not supported.
Multicast MAC addresses with the prefix 01-80-C2-XX-XX is reserved MAC addresses and is
also not supported.
Restrictions
Only Administrator, Operator and Power-User level users can issue this command.
