1.1.4 Transmit-side flow detection mode

The Switch provides sending-side flow detection modes for network configuration and an operation mode. The sending-side flow detection modes determine the distribution pattern of filter entries for the sending-side interface. 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.

Use the flow detection out mode command to specify the sending-side flow detection mode. The selected sending-side flow detection mode takes effect on the filter. To change the sending-side flow detection mode, you need to delete all the following commands set for the receiving-side and sending-side interfaces:

• mac access-group

• ip access-group

• ipv6 traffic-filter

If you do not specify the sending-side flow detection mode, layer3-1-out is set as the default mode.

The following table describes the relationship between the sending-side flow detection modes and flow operations.

Table 1-3: Relationship between flow detection mode on the sending side and flow operation

Sender Flow Detection mode name	Purpose	Flow operations
layer3-1-out	I want to perform flow-control specific to IPv4 packets	For IPv4 packets, frames are detected based on the IP header, TCP/UDP header, and ICMP header.
layer3-2-out	I want to control the flow of IPv4,IPv6 packetsand other frames	Frames are detected based on the MAC header, which contains a MAC address and Ethernet type. IP packet detects frames in IP header, TCP/UDP header, and ICMP header.
