Cisco Systems 3560 사용자 설명서

Beginning in privileged EXEC mode, follow these steps to limit SPAN source traffic to specific VLANs:

To monitor all VLANs on the trunk port, use the no monitor session session_number filter global 
configuration command.

Enter global configuration mode.

no monitor session {session_number | all | 
local | remote}

Remove any existing SPAN configuration for the session.

For session_number, the range is 1 to 66.

Specify all to remove all SPAN sessions, local to remove all local 
sessions, or remote to remove all remote SPAN sessions.

monitor session session_number source 
interface interface-id 

Specify the characteristics of the source port (monitored port) and 
SPAN session. 

For session_number, the range is 1 to 66.

For interface-id, specify the source port to monitor. The interface 
specified must already be configured as a trunk port.

monitor session session_number filter vlan 
vlan-id [, | -]

Limit the SPAN source traffic to specific VLANs.

For session_number, enter the session number specified in Step 3.

For vlan-id, the range is 1 to 4094. 

(Optional) Use a comma (,) to specify a series of VLANs, or use a 
hyphen (-) to specify a range of VLANs. Enter a space before and after 
the comma; enter a space before and after the hyphen.

monitor session session_number 
destination {interface interface-id [, | -] 
[encapsulation replicate]}

Specify the SPAN session and the destination port (monitoring port). 

For session_number, specify the session number entered in Step 3.

For interface-id, specify the destination port. The destination 
interface must be a physical port; it cannot be an EtherChannel, and it 
cannot be a VLAN.

(Optional) [, | -] Specify a series or range of interfaces. Enter a space 
before and after the comma; enter a space before and after the hyphen.

(Optional) Enter encapsulation replicate to specify that the 
destination interface replicates the source interface encapsulation 
method. If not selected, the default is to send packets in native form 
(untagged).

Return to privileged EXEC mode.

show monitor [session session_number]

Verify the configuration.

(Optional) Save the configuration in the configuration file.
