Cisco Switch Port Monitor

[pravin03.singh]

Hi ,

want help on how to monitor Cisco Switch, Router Port open source.

[jbowman1985]

To enable monitoring or SPAN on a Cisco switch you can do the following:

monitor session session-id source interface/vlan

monitor session session-id desitination interface/vlan

Say you wanted to capture both transmit and receive traffic on int fa0/1 and send it to fa0/24 it would be:

monitor session 1 source interface fa0/1

monitor session 1 destination interface fa0/24

You would then connect your laptop to port fa 0/24 and run wireshark to capture any data sent/received on port fa 0/1.

Hello Pravin,

Are you asking monitoring the switches and router via snmp, Then you can try Nagios, Open NMS, Capsa Free or cacti.

If you are asking to check what are service ports are opened on this devices for vulnerbilty purpose, Then i would say try use Nettools or net mapper.

Hope it Helps..
