Hello Rupesh,

I see only half the configiration, Have you configired the span in below fashion.

Configure SPAN

switch# configure terminal
switch(config)# monitor session session-number

Destination Port Configuartion

switch# configure terminal

switch(config)# interface ethernet slot/port

switch(config-if)# switchport monitor

switch(config-if)# exit

switch(config)# monitor session session-number

switch(config-monitor)# destination interface ethernet slot/port

Source Port Configuration

switch(config)# monitor session session-number

switch(config-monitor)# source interface ethernet slot/port

Hope that Helps..

Hi Ganesh,

switch01(config)# interface ethernet 1/40

switch01(config-if)# switchport monitor

switch01(config-if)# exit

switch01(config)# monitor session 1

switch01(config-monitor)# destination interface ethernet 1/40

switch01(config-monitor)# monitor session 1

switch01(config-monitor)# source interface ethernet 1/3

switch01(config-monitor)# do copy running-config  startup-config

Hi Ganesh, did you get bottom of this , I having the same issue.

[asavarin]

Switchport monitor command has to be enabled only destination port . If you enabled "switchport monitor" under  source port then you will observe your session state as "state             : down (Src in wrong mode)" . So remove switchport monitor command under source port.

[Vijay Govindaraj]

Many Thanks asavarin for updating, figured it bit late.
Cheers

Hello

Try the following:

int rang eth1/3,eth1/9
shut

monitor session 1
source interface ethernet 1/3 both
destination interface ethernet 1/9

int ethernet 1/9
switchport monitor
no shut

int eth1/3
no shut
