Hi Frnds
Just to understand something better on SPAN ; I tested sniffing on a port on
diff vlan (but landed in more confusion)
i.e
Rack1SW3(config)#do sh monitor sess 1
Session 1
---------
Type : Local Session
Source Ports :
Both : Fa1/0/9
Destination Ports : Fa1/0/10
Encapsulation : Native
Ingress : Disabled
Rack1SW3(config)#do sh run int f1/0/9
Building configuration...
Current configuration : 62 bytes
!
interface FastEthernet1/0/9
switchport access vlan 10
end
Rack1SW3(config)#do sh run int f1/0/10
Building configuration...
Current configuration : 62 bytes
!
interface FastEthernet1/0/10
switchport access vlan 2
end
Rack1SW3(config)#do sh run int vlan 10
Building configuration...
Current configuration : 55 bytes
!
interface Vlan10
ip address 10.0.0.1 255.0.0.0
end
I am just send some pkts from external source to 10.0.0.1 (src 10.0.0.4 say
)
PC with etherial is connected to f1/0/10
I am able to SNIFF .. Am i doing something wrong ..
As i understand SPAN source and dest need to be in same vlan .
