Parameters
ifa-id: Specifies an INT action ID in the range of 1 to 65535.
user-defined: Specifies a user-defined ACL by its number or name.
acl-number: Specifies the ACL number in the range of 5000 to 5999.
name acl-name: Specifies the ACL name, a case-insensitive string of 1 to 63 characters.
Usage guidelines
After this command is executed, the device adds collected metadata to matching packets on the input interface to calculate the transmission delay of the link.
If the specified ACL does not contain rules, the action is not applied to any packets.
If an ACL is specified in the action of mirroring original packets on the entry node to the INT processor, the ACL specified in this command must contain the same traffic match criteria as that ACL and plus the statement to match the INT flag. The traffic match criteria and the statement to match the INT flag must be in the same ACL rule. For example, if the rule in the ACL in the action of mirroring original packets is rule permit tcp source 10.0.0.3 0, the rule in the ACL in this command must be rule permit tcp source 10.0.0.3 0 ifa l5 aaaaaaaabbbbbbbb ffffffffffffffff 0.
This command and the telemetry ifa role command are mutually exclusive on one interface.
If you execute this command multiple times for the action ID, the most recent configuration takes effect.

# Add collected metadata to incoming packets on HundredGigE 1/0/1 on the transit node.

Parameters
ifa-id: Specifies an INT action ID in the range of 1 to 65535.
acl: Specifies an ACL by its number or name for matching packets. If you do not specify this keyword, the action takes effect on all packets.
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.
sampler sampler-name: Specifies a sampler by its name, a case-insensitive string of 1 to 31. If you do not specify a sampler, all packets are mirrored.
Usage guidelines
After this command is executed, the device samples ACL-matched packets received on the input interface, and mirrors sampled packets to the INT processor. Then, the INT processor adds an INT header to the sampled packets and sends them back to the input interface as INT packets by using internal loopback.
If the specified ACL does not contain rules, the action is not applied to any packets.
To specify an ACL by a number, follow these rules:
· To specify an IPv4 ACL, directly specify the acl-number argument.
? To specify an IPv6 ACL, specify the ipv6 keyword and the acl-number argument.
· To specify a Layer 2 or user-defined ACL, specify the mac or user-defined keyword and the acl-number argument, or directly specify the acl-number argument.
To specify an ACL by a name, follow these rules:
· To specify an IPv4 ACL, directly specify the name acl-name option.
· To specify an IPv6, Layer 2, or user-defined ACL, specify the ipv6, mac, or user-defined keyword and the name acl-name argument
A sampler selects a packet from sequential packets. You can specify a nonexistent sampler and then create it. For more information about samplers, see sampler configuration in Network Management and Monitoring Configuration Guide.
This command and the telemetry ifa role command are mutually exclusive on one interface.
If you execute this command multiple times for the action ID, the most recent configuration takes effect.

Parameters
egress: Specifies the interface as an egress interface.
ingress: Specifies the interface as an ingress interface.
transit: Specifies the interface as a transit interface.
Usage guidelines
In an INT network, specify the interface on the entry node as the ingress interface. Specify the interface on the transit node as the transit interface. Specify the interface on the exit node as the egress interface.
Interfaces in different roles take different actions on incoming packets.
· The ingress interface adds a timestamp and encapsulates the packet as an INT packet.
· The transit interface adds a timestamp for the INT packet.
· The egress interface adds a timestamp, encapsulates the INT packet according to the specified addressing parameters, and sends it to the collector.
This command is mutually exclusive with any command that is used to configure an INT action on one interface.
Examples
# Specify HundredGigE 1/0/1 as the transit interface.
<Sysname> system-view
[Sysname] interface hundredgige 1/0/1
[Sysname-HundredGigE1/0/1] telemetry ifa role transit

Parameters
source source-address: Specifies the source IP address for INT packets.
destination dest-address: Specifies the destination IP address for INT packets.
source-port port: Specifies the source port number for INT packets.
destination-port port: Specifies the destination port number for INT packets.
vlan vlan-id: Specifies a VLAN ID in the range of 1 to 4094.
Usage guidelines
Use this command on the exit node. The exit node uses the addressing parameters to find the outgoing interface for INT packets and sends the packets to the collector.
Do not specify the IP address of the management Ethernet port on the local device for the destination dest-address option.
Examples
# Specify source IP address 1.1.1.1, destination IP address 2.2.2.2, source port number 67, and destination port number 68 for INT packets.
<Sysname> system-view
[Sysname] telemetry ifa collector source 1.1.1.1 destination 2.2.2.2 source-port 67 destination-port 68
