Packet capture configuration examples

Filtering packet data to display configuration example

Network requirements
On Switch A, capture the following incoming IP packets on Ten-GigabitEthernet 1/0/1:
•
Packets forwarded through the CPU.
•
Packets that are sourced from 192.168.56.1 0 and forwarded through chips.
Configuration procedure
# Create an IPv4 advanced ACL to match packets that are sourced from 192.168.56.1 0.
<SwitchA> system-view
[SwitchA] acl number 3000
[SwitchA-acl-adv-3000] rule permit ip source 192.168.56.1 0
[SwitchA-acl-adv-3000] quit
# Configure a traffic behavior to mirror traffic to the CPU.
[SwitchA] traffic behavior behavior1
[SwitchA-behavior-behavior1] mirror-to cpu
[SwitchA-behavior-behavior1] quit
# Configure a traffic class to use the ACL to match traffic.
[SwitchA] traffic classifier classifier1
[SwitchA-classifier-class1] if-match acl 3000
[SwitchA-classifier-class1] quit
# Associate the traffic class with the traffic behavior in a QoS policy.
[SwitchA] qos policy user1
[SwitchA-qospolicy-user1] classifier classifier1 behavior behavior1
[SwitchA-qospolicy-user1] quit
# Apply the QoS policy to the incoming traffic of Ten-GigabitEthernet 1/0/1.
[SwitchA] interface ten-gigabitethernet 1/0/1
[SwitchA-Ten-GigabitEthernet1/0/1] qos apply policy user1 inbound
[SwitchA-Ten-GigabitEthernet1/0/1] quit
# Capture incoming traffic on Ten-GigabitEthernet 1/0/1.
