Traffic Mirroring
Allows you to monitor traffic to detect threats or troubleshoot
problems
Advantages
•Allows you to monitor traffic from the local switch or from multiple
remote switches
•Eliminates the need for a monitoring port on every switch
•Reduces the number of necessary security appliances

Traffic is selected based
on port, VLAN, or ACL.
Selected traffic is mirrored
to another switch.
Destination switch
forwards mirrored
traffic to IDS/IPS.

Guidelines for Using Traffic
Mirroring
Two types of traffic mirroring:
•Local mirroring—source and destination are on the same switch
•Remote mirroring—source and destination are on different switches
Each switch can be the:
•Originator for four mirror sessions, with the destination on either the
local switch or another switch
•Destination for 32 mirror sessions

Four mirror sessions originate on
the local 5400zl Switch.
The 3500yl Switch can receive
up to 28 additional mirror
sessions.

Guidelines for Using Traffic
Mirroring
Continued
For local mirroring, configure exit ports:
•Configure multiple mirror sessions to use the same exit port
•Load balance mirror sessions across multiple exit ports

Overview of Configuration
Steps
1. Configure the destination switch for remote traffic
mirroring.
2. Configure the source switch.
•Define the session number and the destination for the mirror
session on the source switch.
–Local traffic mirroring—port on the same switch
–Remote traffic mirroring—another 3500yl, 5400zl, or 6200yl Switch
•Define the source interface and the direction of traffic
–Ports, including mesh ports
–Static trunks
–Static virtual LANs (VLANs)
–Direction of traffic—inbound, outbound, or both directions
•Apply an optional Access Control List (ACL) to further select traffic.
–Select inbound traffic on the source interface with an extended or
standard ACL

8
Overview of Configuration
Steps
3. For remote traffic mirroring, enable jumbo frames to
mirror information fields larger than 1446 bytes
(untagged) or (tagged)
• On both source and destination switches
• Any infrastructure switches in between
• The end stations, in this case the IPS/IDS if you know the
originating frame was larger than 1522 bytes.

local 5400zl Switch.
The destination is on
the remote 3500yl
Switch.
ProCurve (config)# vlan <vlan_id> jumbo

9
Configuring the Destination
Switch
1. For remote traffic mirroring, configure the source and destination of
the mirror session on the destination switch
ProCurve_dst_switch(config)# mirror endpoint ip <src-ip-add>
<src-udp-port> <dst-ip-add> port <port#>
Options
IP address of the VLAN or subnet for the exit
port on the destination switch
<dst-ip-add>
The unique UDP port number to use for the
session
<src-udp-port>
Exit port on the destination switch
IP address of the VLAN or subnet on which the
mirrored traffic enters or leaves the source
switch
<port#>
<src-ip-add>
These settings
must match the
settings you will
configure on the
source switch.

10
Configuring the Source Switch
Remote traffic mirroring
2. Configure the source switch
—For remote traffic mirroring, identify the mirror session, the source,
and the destination.
–Replace <1-4> with the number to identify this mirror session.
–Assign an optional name if you want an easier way to identify the session.
–Ensure the other settings match those configured on the destination
switch.
ProCurve_source_switch(config)# mirror <1-4> [name <name>]
remote ip <src-ip-add> <src-udp-port> <dst-ip-add>

11
Configuring the Source Switch
Local traffic mirroring
•For local traffic mirroring, identify the session and configure the exit
port
ProCurve_source_switch(config)# mirror <1-4> [name <name>]
port <port#>

Exit port is port 8.

12
Configuring the Source Switch
Define the originating interface
•Define the originating interface as a port, trunk, or mesh port
ProCurve_source_switch(config)# interface <port/trunk/mesh>
monitor all [in | out | both] mirror <1-4> [mirror <1-4> . . .]
Options
Number for this mirror session<1-4>
Direction of traffic that you want mirrored:
in = traffic entering port
out = traffic exiting port
both = all traffic
[in | out | both]
Port, trunk, or mesh<port/trunk/mesh>

13
•Define the originating interface as a VLAN or VLANs
–Replace <vlan-range> with a VLAN or a range or VLANs.
ProCurve_source_switch(config)# vlan <vlan-ID> monitor all [in
| out | both] mirror <1-4> [mirror <1-4> . . .]
Configuring the Source Switch
Select the originating interface
5400zl Switch
Network
VLAN 1
VLAN 2

14
Using an ACL to Further Select
Traffic
Optional
•To use an ACL to select traffic arriving on an interface, enter:
–Replace <acl_name> with the name of the ACL you have configured.
ProCurve_source_switch(config)# interface <port/trunk/mesh>
monitor ip access-group <acl_name> in mirror <1-4> [mirror
<1-4> . . .]
ProCurve_source_switch(config)# vlan <vlan-ID> monitor ip
access-group <acl_name> in mirror <1-4> [mirror <1-4> . . .]

15
Enabling Jumbo Frames
3. For remote traffic mirroring, enable jumbo frames on the
source switch, destination switch, and any intervening
infrastructure switches
For example:
ProCurve_Source (config)# vlan 8 jumbo
ProCurve_Destination (config)# vlan 8 jumbo
ProCurve_Infrastructure (config)# vlan 8 jumbo
