The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of HP port mirroring and flow mirroring.

Example: Configuring local port mirroring

Network configuration

As shown in Figure 1, configure local port mirroring to monitor the Internet traffic and bidirectional traffic of the Marketing department and the Technical department.

Figure 1 Network diagram

Applicable hardware and software versions

The following matrix shows the hardware and software versions to which this configuration example is applicable:

Hardware	Software version
S12500G-AF	Release 8053P05 and later
S12500CR	Release 8053P05 and later
S10500X-G	Release 7753P05 and later
S7500X-G	Release 7753P05 and later

Restrictions and guidelines

When you configure local port mirroring, follow these restrictions and guidelines:

· A local mirroring group takes effect only when you configure both source ports and the monitor port for the group. When you configure the monitor port, do not use a port of an existing mirroring group.

· Use a monitor port only for port mirroring, so the data monitoring device receives and analyzes only the mirrored traffic.

· For the correct operation of port mirroring, disable the spanning tree feature on the monitor port if it is a Layer 2 interface.

S10500X-G	Release 7753P05 and later
S7500X-G	Release 7753P05 and later

Restrictions and guidelines

When you configure devices for remote port mirroring, configure them in the order of the destination device, the intermediate devices, and the source device.

When you configure the monitor port for the remote destination group on the destination device, follow these restrictions and guidelines:

· Do not use a port of an existing mirroring group.

· Use the monitor port only for port mirroring.

· For the correct operation of port mirroring, disable the spanning tree feature on the monitor port if it is a Layer 2 interface.

· For the monitor port to forward mirrored packets to the data monitoring device without VLAN tags, assign the monitor port to the remote probe VLAN as an access port.

When you configure the remote probe VLAN on the source and destination devices, follow these restrictions and guidelines:

· Use an existing static VLAN that is not in use.

· Use the remote probe VLAN for port mirroring exclusively.

· The remote mirroring groups on the source device and destination device must use the same remote probe VLAN. Use this VLAN only for the same remote mirroring group on the source device and destination device.

When you configure a remote source group on the source device, follow these restrictions and guidelines:

· Do not assign source ports of the remote source group to the remote probe VLAN.

· To ensure the operation of mirroring, do not enable any of the following features on the egress port:

¡ Spanning tree.

¡ 802.1X.

¡ IGMP snooping.

¡ Static ARP.

¡ MAC address learning.

· A port of an existing mirroring group cannot be configured as an egress port.

· A mirroring group contains only one egress port.

· To implement Layer 2 remote mirroring when the source ports are Layer 3 interfaces, you must use the egress port method.

Example: Configuring flow mirroring in a flexible way

Network configuration

As shown in Figure 9, configure flow mirroring to monitor the network traffic by using the data monitoring devices as follows:

· On the data monitoring device connected to Device A:

¡ Monitor the traffic from public servers.

¡ Monitor the traffic from the file server only in the non-working hours (18:00 to 8:30 of the next day) on working days.

¡ Monitor the traffic from the Marketing department to the Internet, except the traffic from the Marketing department manager office to the Internet.

· On the data monitoring device connected to Device B:

¡ Monitor the traffic from the Technical department hosts and the server for external access.

¡ Monitor the outgoing traffic from the server in non-working hours (18:00 to 8:30 of the next day) on working days.

Figure 9 Network diagram

Analysis

To filter data from a specific source, use one of the following methods:

· Apply a QoS policy of denying traffic to the outgoing interface of the mirrored data. The data from the specified source is not received by the data monitoring device.

· Configure a class-behavior association to permit the data from the specified source, and then issue the class-behavior association before the class-behavior association for mirroring. Data from the specified source is not mirrored.

· Use the packet-filter command on the outgoing interface of the mirrored data. The data from the specified source is not received by the data monitoring device.

Procedures

Configuring Device A to mirror traffic from the public servers

1. Configure a QoS policy to mirror traffic from all public servers:

# Create ACL 2000 to match packets from subnet 14.1.1.0/24.

<DeviceA> system-view

[DeviceA] acl number 2000

[DeviceA-acl-basic-2000] rule permit source 14.1.1.0 0.0.0.255

[DeviceA-acl-basic-2000] quit

# Create traffic class classifier_servers, and configure the match criterion as ACL 2000.

[DeviceA] traffic classifier classifier_servers

[DeviceA-classifier-classifier_servers] if-match acl 2000

[DeviceA-classifier-classifier_servers] quit

# Create traffic behavior behavior_servers, and configure the action of mirroring traffic to Ten-GigabitEthernet 3/0/3.

[DeviceA] traffic behavior behavior_servers

[DeviceA-behavior-behavior_servers] mirror-to interface ten-gigabitethernet 3/0/3

[DeviceA-behavior-behavior_servers] quit

# Create QoS policy policy_servers, and associate traffic class classifier_servers with traffic behavior behavior_servers in the QoS policy.

[DeviceA] qos policy policy_servers

[DeviceA-qospolicy-policy_servers] classifier classifier_servers behavior behavior_servers

[DeviceA-qospolicy-policy_servers] quit

# Apply QoS policy policy_servers to the inbound direction of Ten-GigabitEthernet 3/0/4.

[DeviceA] interface ten-gigabitethernet 3/0/4

[DeviceA-Ten-GigabitEthernet3/0/4] qos apply policy policy_servers inbound

[DeviceA-Ten-GigabitEthernet3/0/4] quit

2. Configure a QoS policy to filter packets from the file server in working hours:

# Create a periodic time range work-time, setting it to be active between 8:30 and 18:00 during working days.

[DeviceA] time-range work-time 8:30 to 18:00 working-day

# Create ACL 2001, and configure a rule to match packets from 14.1.1.10 in working hours on working days.

[DeviceA] acl number 2001

[DeviceA-acl-basic-2001] rule permit source 14.1.1.10 0.0.0.0 time-range work-time

[DeviceA-acl-basic-2001] quit

# Create traffic class classifier_fileserver, and configure the match criterion as ACL 2001.

[DeviceA] traffic classifier classifier_fileserver

[DeviceA-classifier-classifier_fileserver] if-match acl 2001

[DeviceA-classifier-classifier_fileserver] quit

# Create traffic behavior behavior_fileserver, and configure the action of denying traffic.

[DeviceA] traffic behavior behavior_fileserver

[DeviceA-behavior-behavior_fileserver] filter deny

[DeviceA-behavior-behavior_fileserver] quit

# Create QoS policy policy_fileserver, and associate traffic class classifier_fileserver with traffic behavior behavior_fileserver in the QoS policy.

[DeviceA] qos policy policy_fileserver

[DeviceA-qospolicy-policy_fileserver] classifier classifier_fileserver behavior behavior_fileserver

[DeviceA-qospolicy-policy_fileserver] quit

# Apply QoS policy policy_fileserver to the outbound direction of Ten-GigabitEthernet 3/0/3.

[DeviceA] interface ten-gigabitethernet 3/0/3

[DeviceA-Ten-GigabitEthernet3/0/3] qos apply policy policy_fileserver outbound

[DeviceA-Ten-GigabitEthernet3/0/3] quit

Configuring Device A to mirror the Internet traffic from the Marketing department

1. Create a traffic class and a traffic behavior for the packets:

# Create ACL 3000, and configure a rule to match packets from subnet 12.1.1.0/24.

[DeviceA] acl number 3000

[DeviceA-acl-adv-3000] rule permit tcp destination-port eq 80 source 12.1.1.0 0.0.0.255

[DeviceA-acl-adv-3000] quit

# Create traffic class classifier_market, and configure the match criterion as ACL 3000.

[DeviceA] traffic classifier classifier_market

[DeviceA-classifier-classifier_market] if-match acl 3000

[DeviceA-classifier-classifier_market] quit

# Create traffic behavior behavior_market, and configure the action of mirroring traffic to Ten-GigabitEthernet 3/0/3.

[DeviceA] traffic behavior behavior_market

[DeviceA-behavior-behavior_market] mirror-to interface ten-gigabitethernet 3/0/3

[DeviceA-behavior-behavior_market] quit

2. Create a traffic class and a traffic behavior for the packets from the manager office:

# Create ACL 3001, and configure a rule to match packets from 12.1.1.100.

[DeviceA] acl number 3001

[DeviceA-acl-adv-3001] rule permit tcp destination-port eq 80 source 12.1.1.100 0.0.0.0

[DeviceA-acl-adv-3001] quit

# Create traffic class classifier_market_mgr, and configure the match criterion as ACL 3001.

[DeviceA] traffic classifier classifier_market_mgr

[DeviceA-classifier-classifier_market_mgr] if-match acl 3001

[DeviceA-classifier-classifier_market_mgr] quit

# Create traffic behavior behavior_market_mgr, and configure the action of permitting traffic to pass through.

[DeviceA] traffic behavior behavior_market_mgr

[DeviceA-behavior-behavior_market_mgr] filter permit

[DeviceA-behavior-behavior_market_mgr] quit

3. Create a QoS policy and associate the traffic classes and traffic behaviors:

# Create QoS policy policy_market.

[DeviceA] qos policy policy_market

# Associate traffic class classifier_market_mgr with traffic behavior behavior_market_mgr in the QoS policy.

[DeviceA-qospolicy-policy_market] classifier classifier_market_mgr behavior behavior_market_mgr

# Associate traffic class classifier_market with traffic behavior behavior_market in the QoS policy.

[DeviceA-qospolicy-policy_market] classifier classifier_market behavior behavior_market

# Display the sequence of issuing the class–behavior associations.

[DeviceA-qospolicy-policy_market] display this

qos policy policy_market

classifier classifier_market_mgr behavior behavior_market_mgr

classifier classifier_market behavior behavior_market

return

[DeviceA-qospolicy-policy_market] quit

The output shows that the class–behavior association for the manager office are issued first. The packets from the manager office to access the Internet are not mirrored.

4. Apply QoS policy policy_market to the inbound direction of Ten-GigabitEthernet 3/0/2.

[DeviceA] interface ten-gigabitethernet 3/0/2

[DeviceA-Ten-GigabitEthernet3/0/2] qos apply policy policy_market inbound

[DeviceA-Ten-GigabitEthernet3/0/2] quit

Configuring Device B to mirror traffic from the Technical department

1. Configure local mirroring on Device B:

# Create local mirroring group 1.

<DeviceB> system-view

[DeviceB] mirroring-group 1 local

# Configure the mirroring group to monitor the incoming traffic of the port Ten-GigabitEthernet 3/0/1.

[DeviceB] mirroring-group 1 mirroring-port ten-gigabitethernet 3/0/1 inbound

# Configure Ten-GigabitEthernet 3/0/2 as the monitor port of the mirroring group.

[DeviceB] mirroring-group 1 monitor-port ten-gigabitethernet 3/0/2

2. Configure an ACL to filter the outgoing traffic from the server (10.1.1.2) in working hours:

# Create a periodic time range work-time, setting it to be active between 8:30 and 18:00 during working days.

[DeviceB] time-range work-time 8:30 to 18:00 working-day

# Create ACL 2000, and configure a rule to deny packets from 10.1.1.2 in working hours on working days.

[DeviceB] acl number 2000

[DeviceB-acl-basic-2000] rule deny source 10.1.1.2 0.0.0.0 time-range work-time

[DeviceB-acl-basic-2000] quit

# Apply ACL 2000 to filter the outgoing traffic on Ten-GigabitEthernet 3/0/2.

[DeviceB] interface ten-gigabitethernet3/0/2

[DeviceB-Ten-GigabitEthernet3/0/2] packet-filter 2000 outbound

[DeviceB-Ten-GigabitEthernet3/0/2] quit

Verifying the configuration

1. Verify flow mirroring configurations on devices:

Mirroring port:

Ten-GigabitEthernet3/0/1 Inbound

Monitor port: Ten-GigabitEthernet3/0/2

2. Use Wireshark for packet analysis:

# Use a Marketing department host (12.1.1.2) and the manager's host (12.1.1.100) to access the IP address 57.57.57.7 and port 80 through Telnet. (Details not shown.)

# Use Wireshark on the data monitoring device connected to Device A to capture the packets.

Figure 10 HTTP traffic analysis in Wireshark

The analysis shows that the data monitoring device monitors the traffic only from the Marketing department host (12.1.1.2). The traffic from the manager office is not monitored.
