Log in to the backbone fabric and set up the TI zone.
a. Issue the following commands to create and display a TI zone:

10:00:00:00:00:08:00:00; 10:00:00:00:00:02:00:00; 10:00:00:00:00:03:00:00"
BB_DCX_1:admin> zone --show
Defined TI zone configuration:

b. Issue the following commands to reactivate your current effective configuration and enforce the TI
zones.
BB_DCX_1:admin> cfgactvshow

QoS: ingress rate limiting
Ingress rate limiting is a licensed feature that restricts the speed of traffic from a particular device. Use
ingress rate limiting for the following situations:
•
To reduce existing congestion in the network or proactively avoid congestion.
•
To enable you to offer flexible bandwidth limit services based on requirements.
•
To enable more important devices to use the network bandwidth during specific services, such as
network backup.
To limit the traffic, you set the maximum speed at which the traffic can flow through a particular F_Port or
FL_Port. For example, if you set the rate limit at 4 Gbps, traffic from a particular device is limited to a
maximum of 4 Gbps.
Ingress rate limiting enforcement is needed only if the port can run at a speed higher than the rate limit. For
example, if the rate limit is 4 Gbps and the port is only a 2 Gbps port, ingress rate limiting is not enforced.
The ingress rate limiting configuration is persistent across reboots.
NOTE:
Ingress rate limiting is applicable only to F_Ports and FL_Ports and is available only on the DC
Director model.
To limit traffic from a particular device:
