Configuration Guide Vol. 2


3.1.1 Flow detection mode

The Switch provides a flow detection mode assuming a network configuration and an operation configuration. The flow detection mode determines the distribution pattern of filter QoS entries. For details about how to allocate entries, see Vol.1" "3 Capacity Limits in the Configuration Guide and select the appropriate setting for the usage.

The flow detection mode is specified by flow detection mode commandI will. The selected flow-detection mode is the same for both the receiver and sender in the filter QoS,. When you change the flow detection mode, you must delete all the following commands configured on the interface:

If no flow detection mode is specified, layer2-1 defaults to the mode.

The following table shows the relationship between flow detection mode and flow operation.

Purpose

Flow operations

layer2-1

I want to control the flow with MAC headers (including VLAN Tag)

For all frames, the frame is detected by MAC headers such as MAC address/Ethernet type.

layer2-2

I want to control the flow with IPv4 headers and L4 headers

For IPv4 packets, frames are detected based on the IP header, TCP/UDP header, and ICMP header.

layer2-3

I want to control flows with IPv4 headers, IPv6 headers, and L4 headers

For IPv4 or IPv6 packets, frames are detected in IP header, TCP/UDP header, and ICMP header.
