Configuring Layer 3 Interfaces
Configuring the Bandwidth on an Interface
You can configure the bandwidth for a routed interface, port channel, or subinterface. Higher layer
protocols use bandwidth parameter to calculate path costs. You can configure the bandwidth on a
subinterface with one of the following methods:
• Explicit—Set the bandwidth value for the subinterface directly.
• Inherit—Set the bandwidth that all subinterfaces inherit from the parent interface as either a specific
value or as the bandwidth of the parent interface.
If you do not set the subinterface bandwidth or configure it to inherit the bandwidth from the parent
interface, Cisco NX-OS determines the subinterface bandwidth as follows:
• If the parent interface is up, then the bandwidth of the subinterface is the same as the operational
speed of the parent interface. For ports, the subinterface bandwidth is the configured or negotiated
link speed. For port channels, the subinterface bandwidth is the aggregate of the link speeds of
individual members of the port channel.
• If the parent interface is down, then the bandwidth of the subinterface depends on the type of parent
interface:
– Port-channel subinterfaces have 100-Mb/s bandwidth for subinterfaces.
– 1-Gb/s Ethernet ports have 1-Gb/s bandwidth for subinterfaces.
– 10-Gb/s Ethernet ports have 10-Gb/s bandwidth for subinterfaces.
To configure the bandwidth of an interface, use the following command in interface mode:
To configure subinterfaces to inherit the bandwidth from the parent interface, use the following
command in interface mode:
Configuring a VLAN interface
You can create VLAN interfaces to provide inter-VLAN routing.
BEFORE YOU BEGIN
Ensure that you are in the correct VDC (or use the switchto vdc command).
Command Purpose
bandwidth
Example:
switch(config-if)# bandwidth 100000
Configures the bandwidth parameter for a routed
interface, port channel, or subinterface.
Command Purpose
bandwidth inherit [value]
Example:
switch(config-if)# bandwidth inherit
100000
Configures all subinterfaces of this interface to
inherit the bandwidth value configured. If you do
not configure the value, the subinterfaces inherit
the bandwidth of the parent interface. The range is
from 1 to 10000000, in kilobytes.
