Configuring VLAN Rate Limit

Rate limiting per VLAN, performed on the VLAN Ingress Rate Limit page, enables
traffic limiting on VLANs. QoS rate limiting (configured on the Policy Table page)
has priority over VLAN rate limiting. 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.
When VLAN ingress rate limiting is configured, it limits aggregate traffic from all
ports on the switch.
VLAN rate limiting is configured at the device level and rate limits are applied
independently for each device in the network. If there is more than one device in
the system, the configured VLAN rate limit values will be applied on each of the
devices independently.
This feature requires that the switch is in QoS basic mode or in QoS advanced
mode.
To define the VLAN ingress rate limit:
Click Quality of Service > General > VLAN Ingress Rate Limits.
Click Add.
Enter the following information:
• VLAN ID—Select a VLAN.
• Committed Information Rate (CIR)—Enter the average maximum amount
of data that can be accepted into the VLAN in Kilobytes per second.
Click Apply. The Running Configuration is updated.
Configuring VLAN Port Rate Limit
Rate limiting per VLAN port, performed on the VLAN Port Ingress Rate Limit page,
enables traffic limiting on the ports that are bound to a specific VLAN.
When VLAN port ingress rate limiting is configured, it limits aggregate traffic from
the specified ports on the switch.
This features requires that the switch is in QoS basic mode or in QoS advanced
mode.
