VLAN Ingress Rate Limit

Rate limiting per VLAN, performed in the VLAN Ingress Rate Limit page, enables traffic limiting on VLANs. When VLAN ingress rate limiting is configured, it limits aggregate traffic from all the ports on the device.

The following constraints apply to rate limiting per VLAN:

  • It has lower precedence than any other traffic policing defined in the system. For example, if a packet is subject to QoS rate limits but is also subject to VLAN rate limiting, and the rate limits conflict, the QoS rate limits take precedence.

To define the VLAN ingress rate limit, complete the following steps:

Procedure

Step 1

Click Quality of Service > General > VLAN Ingress Rate Limit.

This page displays the VLAN Ingress Rate Limit Table.

Step 2

Click Add.

Step 3

Enter the parameters.

  • VLAN ID—Select a VLAN.

  • Committed Information Rate (CIR)—Enter the average maximum amount of data that can be accepted into the VLAN in Kilobits per second.

Step 4

Click Apply. The VLAN rate limit is added, and the Running Configuration file is updated.
