if-match acl
Use if-match acl to specify an ACL for a flow group.
Use undo if-match acl to remove an ACL from a flow group.

undo if-match acl
Default
No ACL is specified for a flow group.

Predefined user roles
network-admin
Parameters
ipv6: Specifies the IPv6 ACL type.
mac: Specifies the Layer 2 ACL type.
user-defined: Specifies the user-defined ACL type.
acl-number: Specifies the ACL number. The following are available value ranges:
· 2000 to 2999 for basic ACLs.
· 3000 to 3999 for advanced ACLs.
· 4000 to 4999 for Layer 2 ACLs.
· 5000 to 5999 for user-defined ACLs.
name acl-name: Specifies the ACL name, a case-insensitive string of 1 to 63 characters. The ACL name must start with an English letter.
Usage guidelines
When specifying an ACL, follow these restrictions and guidelines:
· If the specified ACL does not exist or does not have any rules, no traffic will match the ACL.
· In the specified ACL, a rule with the vpn-instance keyword specified takes effect only on VPN packets, and a rule without the vpn-instance keyword specified takes effect on both packets in the public network and VPN packets.
When specifying an ACL by its number, follow these rules:
· To specify an IPv4 ACL, specify only its number.
· To specify an IPv6 ACL, Layer 2 ACL, or user-defined ACL, you must specify both its type and number.
When specifying an ACL by its name, follow these rules:
· To specify an IPv4 ACL, specify only its name.
· To specify an IPv6 ACL, Layer 2 ACL, or user-defined ACL, you must specify both its type and name.
A flow group takes effect only on the traffic that matches the specified ACL.
Only one ACL can be specified for a flow group.
Examples
# Specify ACL 3000 in flow group 1.
<Sysname> system-view
[Sysname] telemetry flow-group 1
[Sysname-telemetry-flow-group-1] if-match acl 3000

Parameters
group-id: Specifies a flow group ID. The value range for this argument is 1 to 7.
name group-name: Specifies a flow group name, a case-sensitive string of 1 to 63 characters. The name must be globally unique and cannot start with system-defined-.
mode: Specifies a flow group mode. The default is MOD mode.
· simple-mod: Specifies the simple MOD mode.
· delay-monitor: Specifies the delay monitoring mode.
· mod-delay-monitor: Specifies the common MOD+delay monitoring mode.
Usage guidelines
The flow entries generated by a flow group can be used by other features. A flow group can be in one of the following modes:
· Common MOD mode—Used by MOD. This mode occupies hardware resources but has a lower burden on the CPU.
· Simple MOD mode—Used by MOD. This mode has a higher burden on the CPU but saves hardware resources.
· Delay monitoring mode—Generates flow entries when a packet exceeds the delay threshold and reports the event through gRPC. To use this mode, you must configure the gRPC dial-out mode and specify sensor path telemetryftrace/genevent in a sensor group. For more information about gRPC, see Telemetry Configuration Guide.
· Common MOD+delay monitoring mode—Provides basic data for MOD and monitors delay threshold violation events. To use this mode, you must configure both MOD and the gRPC dial-out mode, and specify sensor path telemetryftrace/genevent in a sensor group.
You cannot name or rename an existing flow group and cannot modify the mode of an existing flow group.
To delete an applied flow group, first remove the application and then delete the flow group.
Examples
# Create flow group 1 in MOD mode and enter its view.
<Sysname> system-view
[Sysname] telemetry flow-group 1
[Sysname-telemetry-flow-group-1]
# Create flow group 3 in simple MOD mode and enter its view.

If an IPv4 ACL has been specified for the flow group, only the destination-ip, source-ip, inner-destination-ip, inner-source-ip, and vxlan-id keywords in this command can be configured. The inner-destination-ip keyword represents the inner destination IP address of VXLAN packets. The inner-source-ip keyword represents the inner source IP address of VXLAN packets. The vxlan-id keyword represents the VXLAN ID of VXLAN packets.
