Port Mirroring in cisco 3560 Catalist


Hi ,

 I have to do port mirroring in extended switch . 

Case :- I have 4 SWITCHES with 2 VLANS connected to each other . Vlans area vlan 10 and VLAN 20 .

VLAN 10 -- voip phones are connected in each switches 

VLAN 20 --- other Devices 

Switch 1  Vlan 10 (gig/26-43) and VLAN 20 (Gig/1-24)

Switch 2  Vlan 10 (gig/26-43) and VLAN 20 (Gig/1-24)

Extended Switch 1  Vlan 10 (gig/1-23) 

Extended Switch 2  Vlan 10 (gig/1-23) 

In  PORT 44 of switch 1 recorder is connected , We have to record all the voip phones connected to all the 4 switches . 

Case1 :- Voip CONNECTED TO SWITCH1  is getting recorded but voip connected to other switches (Switch 2, extended Switch 1 and 2 ) are not getting recorded . 


So i have to start recording of all the phones . So Below is the configuration done :-

Switch 1---(For Port Mirroring )

monitor session 1 source interface Gi0/26 - 43

monitor session 1 destination interface Gi0/44

Switch 2 ---(For Port Mirroring )

monitor session 1 source remote vlan 10


So what configuration changes i can made so that i can record all the voip Phones .


Spanning tree is enable in all the switches / entire networks .
