}
}
Syntax Description
|
Specifies to automatically rebalance VLAN interfaces on available replicators. |
|
Specifies to manually rebalance VLAN interfaces on available replicators using the command-line interface (CLI). |

5.1(1) |
This command was introduced. |
Usage Guidelines
This command applies only to the Cisco Nexus 7000 Series chassis that contains an F1 Series module or an M1 Series module. This command applies when you are using either a FabricPath or Ethernet interface.
Note The system automatically balances all Layer 3 routing traffic among the available proxy routing interfaces on the M Series modules in the chassis.
This command does not require a license.
Examples
This example shows how to automatically rebalance VLAN interfaces on available replicators:
switch(config)# hardware proxy layer-3 replication rebalance-mode auto
This example shows how to manually rebalance VLAN interfaces on available replicators using the CLI:
switch(config)# hardware proxy layer-3 replication rebalance-mode manual

hardware proxy layer-3 replication
To configure specific modules and physical interfaces on the N7K-M Series module to provide the proxy routing for egress replication of Layer 3 multicast packets on the N7K-F Series module, use the hardware proxy layer-3 replication command. To delete the user configuration and to use all M-series modules in the virtual device context (VDC) for egress replication, use the no form of this command.
