Monitor session
To start a new SPAN or RSPAN session, add or delete interfaces or VLANs to or from an existing SPAN or RSPAN session, filter SPAN or RSPAN traffic to specific VLANs, or delete a SPAN or RSPAN session, use the monitor session command. Use the OR DELETE A Source VLAN from The span or iv or rspan session.

Command History
Release Modification 12.0 (7) XE Support for this command was introduced on the Catalyst 6500 series switches. 12.1 (1) E Support for this command on the Catalyst 6500 series switches was extended to the 12.1 E release. 12.1 (3a) E3 The number Of Valid Values for Port-Channel-Number Was Changed; See The "Usage Guidelines" Section for Valid Values. 12.1 (5C) Exped SPN Support Restrictions Were Added: •
IF Your Catalyst 6500 Series Switch Has A Switch Fabric Module Installed, Span IS Supported Among Supervisor Engines and Nonfabric-enabled modules.
If your Catalyst 6500 series switch does not have a Switch Fabric Module installed, SPAN is supported on all modules including fabric-enabled modules. • SPAN on DFC-equipped modules is not supported. 12.1 (11b) E This command was changed to include the POS, ATM, AND GE-WAN Keywords. 12.1 (11B) E This Command Was Changed To Support Span on DFC-Equipped Modules. 12.1 (11B) EX The Command Was Changed To Support Extended-Range Vlans. 12.1 (13) E this Command Was Changed to Support Rspan.
USAGE Guidelines
Use these Formatting Guidelines WHEN Configuring Monitor Sessions:
•
Interface and single-interface formats are type slot / port; valid value for Type Aree Ethernet, Fastethernet, GigabitEthernet, or tengigabitEthernet.
•
An interface-list is a list of interfaces That Are Separated by Commas. Insert A Space Before and After Each Comma As Shown in this Example:
SINGLE-Interface, Single-Interface, Single-Interface ...
•
An Interface-Range IS A Range of Interfaces Separated by Dashes. Insert a Space Before and After Each Dash. To Enter Multiple Ranges, Separate Each Range with a comma as shown in this Example:
TYPE SLOT / FIRST-Port - Last-Port, First-Port - Last-Port
•
A Mixed-Interface-List Is A Mixed List of Interfaces. Insert a Space Before and After Each Dash and Comma As Shown in this Example:
SINGLE-Interface, Interface-Range, ... in Any ORDER.
•
A SINGLE-VLAN IS An ID Number of a Single VLAN; Valid Values Are FROM 1 to 4094.
•
A vlan-list is a list of vlan ids what are subjectid by Commas. An Example Is Shown as Follows:
SINGLE-VLAN, SINGLE-VLAN, SINGLE-VLAN ...
•
A VLAN-RANGE IS A RANGE OF VLAN IDS That Are Separated by Dashes. AN Example Is Shown As Follows:
First-VLAN-ID - Last-VLAN-ID
•
A Mixed-VLAN-List Is A Mixed List of VLAN IDS. Insert A Space Before and After Each Dash. TO ENTER MULTIPLE RANGES, SEPARATE EACH VLAN ID WITH A COMMA AS Shown In this Example: SINGLE-VLAN, VLAN-RANGE,. .. in any ORDER
.
THE NUMBER OF VALID VALUES for Port-Channel Number Depends on The Software Release. For Releases Prior To Release 12.1 (3A) E3, Valid Values Are From 1 To 256; for Releases 12.1 (3A) E3, 12.1 (3A) E4, AND 12.1 (4) E1, VALID VALUES ARE from 1 to 64. Release 12.1 (5C) EX AND LATER Support a Maximum of 64 Values Ranging from 1 to 256. Release 12.1 (13) E and Later Support a Maximum of 64 Values Ranging from 34 VALUES RANGING FROM 1 to 282; Values 257 to 282 AresuTed on the csm and fwsm only.
If your system is configured with a Supervisor Engine 1, valid values for vlan-id are from 1 to 1005. If your system is configured with a Supervisor Engine 2, valid values for vlan-id are from 1 to 4094. Extended-range VLANs Are Not Supported On Systems Configured With A Supervisor Engine 1.
You canNot Share Destination Interfaces Among Span Sessions. For Example, a Single Destination Interface CAN Belong To One Span Session Only And Cannot Be Configured As a Destination Interface In another span session.
You can configure up to 64 span destination interfaces but you can have one egress span source interface and up to 64 ingress source interfaces only.
A particular SPAN session can either monitor VLANs or monitor individual interfaces-you can not have a SPAN session that monitors both specific interfaces and specific VLANs. If you first configure a SPAN session with a source interface, and then try to add a source VLAN to the same SPAN session, you will get an error. you will also get an error if you configure a SPAN session with a source VLAN and then try to add a source interface to that session. you must first clear any sources for a SPAN session before switching To another Type of Source.if You Enter The Filter Keyword ON A Monitored Trunk Interface, Only Traffic On The Set of Specified Vlans IS Monitored.
Port channel interfaces display in the list of interface options if you have them configured. VLAN interfaces are not supported. However, you can span a particular VLAN by entering the monitor session session source vlan vlan-id command.
Examples
This Example Shows How To Configure Multiple Sources for A Session:
Router (config) # Monitor session 2 Source Interface Fastethernet 5/15, 7/3 RX
Router (config) # Monitor session 2 Source Interface GigabitEthernet 1/2 TX
Router # Monitor Session 2 Source Interface Port-Channel 102
Router (config) # Monitor session 2 Source Filter VLAN 2 - 3
Router (config) # Monitor Session 2 Destination Remote VLAN 901
This Example Shows How To Configure An Rspan Destination In The Final Switch (Rspan Destination Session):
Router (config) # Monitor session 8 Source Remote VLAN 901
Router (config) # Monitor session 8 Destination Interface Fastethernet 1/2, 2/3
This Example Shows How To Clear The Configuration For Sessions 1 and 2:
Router (config) # no monitor session 1 - 2
Router (config) #
This Example Shows How To Clear The Configuration for All Sessions: Router (config) # no monitor session all
Router (config) #
This Example Shows How To Clear The Configuration for All Remote sessions:
Router (config) # no monitor session remote
Router (config) #
