SPAN 2960

[Rohmat Tri Indra]

After configuring SPAN on 2960, IDS can't connect to anything, IDS & PC client same switch on 2960

Please correct the below configuration.

interface GigabitEthernet0/1

switchport access vlan 8

!

interface GigabitEthernet0/11

monitor session 1 source interface Gi0/2

monitor session 1 destination interface Gi0/3

Switch#sh monitor

Session 1

---------

Type                        : Local Session

Source Ports            :

Both                        : Gi0/2

Destination Ports      : Gi0/3

Encapsulation          : Native

Ingress                    : Disabled

check the output rate on the destination interface. 2960 uses shared buffer. Make sure the span is not overwhelming the buffer available.

Hi All,

Is there supported document that said about buffer/cpu consumption at Cat-2960 during running SPAN monitor ?

Thanks,
