1.1.3 Flow detection mode
The Switch provides a flow detection mode assuming a network configuration and an operation configuration. Flow detection mode determines the distribution pattern of entries for filter QoS policy-based mirroring. 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 filter QoS policy-based mirroring and is the same for both the receiver and sender. When you change the flow detection mode, you must delete all the following commands configured on the interface:
-
mac access-group
-
ip access-group
-
ipv6 traffic-filter
-
mac qos-flow-group
-
ip qos-flow-group
-
ipv6 qos-flow-group
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.
|
Flow detection mode name |
Purpose |
Flow operations |
|---|---|---|
|
layer2-1 |
I want to use filters in 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 use filters in 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 use filters in IPv4 headers, IPv6 headers, and L4 headers |
For IPv4 or IPv6 packets, frames are detected in IP header, TCP/UDP header, and ICMP header. |
|
layer2-1-mirror |
I want to use filters and policy-based mirroring on MAC headers (including VLAN Tag) |
For all frames, the frame is detected by MAC headers such as MAC address/Ethernet type. |
|
layer2-2-mirror |
I want to use filters and policy-based mirroring in IPv4 headers and L4 headers |
For IPv4 packets, frames are detected based on the IP header, TCP/UDP header, and ICMP header. |
