How to check user bandwidth when connected to a Cisco ASA SSL VPN 5520 box ?

[sanjay.nadarajah]

Hi,

I have a Cisco ASA SSL VPN 5520 concentrator device, version 8.0(4)39 and would like to know how can I find out

the bandwidth used by each SSL user when they are connected to the VPN concentrator.

Many thanks.

Cheers,

You can  use  asdm  monitoring TAB  ,   load your asdm and  go  to   Monitorin>VPN>VPN Statistics> Sessions   ,   under Filter by  field  select Clientss SSL VPN,  you can then see  Tx/Rx Bytes per SSL VPN session  ,  you can use the refresh   key at the bottom of the screen  to refresh the bytes received/transmit statistics ,   with this information    you can see how much traffic each session is using.

Another way would be to use managemt software to collect and  record these types of information  like Cisco Security  manager  http://www.cisco.com/en/US/partner/products/ps6498/index.html   ,

or use Firewall Analyzer http://www.manageengine.com/products/firewall/download.html

As to  finding out in real time how much bandwidth   each connection is actually using you will need to implement  Netflow   on a device that supports this feature   such as a router behind your firewall  ,   ASA supports netflow but has limitations and do not believe will provide bandtwidth details  per connections as a router would.   http://www.cisco.com/en/US/partner/products/ps6601/products_ios_protocol_group_home.html

Good luck
