VLAN-based rate-limiting

VLAN-based rate-limiting provides specific bandwidth for a specific VLAN for the inbound traffic on the VLAN. It allows the user to specify the maximum number of kilobits per second (kbps) a VLAN can receive. The specified VLAN drops all traffic that exceeds the configured rate. Unused bandwidth is not carried over from one interval to the next.

VLAN-based rate limiting and rate limiting per interface/port are supported together on the same port. If applying any of these rate-limit configurations results in blocking the inbound traffic on that port, further packets on that port are dropped. Any VLAN-based rate limiting applies to all traffic on that VLAN.

Global QoS priority policies and rate limit policies cannot be configured at the same time.

VLAN-based rate limiting is disabled by default.

	NOTE: VLAN-based rate limiting does not work on broadcast traffic. The hardware design lowers the priority of broadcast traffic to avoid flooding the CPU.

	NOTE: The HP Switch supports data rate in multiples of 64 kbps. If the configured value is between 1-63, it is rounded off to 64. For all other non-zero values, it is rounded off to the nearest lower multiple of 64, and the rate-limit is applied

HP Switch(vlan-1)# rate-limit all in kbps <rate>

Usage: rate-limit all in kbps <rate>
       no rate-limit all in

all: Set limits for all traffic
in : Set limits for all inbound traffic
