I desire to block video streaming on my network. youtube et al pending the time i have approval for a welb filtering solution


You can not do content filtering with ASA firewalls with IOS. You will need to buy a content filtering solution, or sign up for a inexpensive content filtering with OpenDNS.org. This is a good content filtering basic system with white and black listing capability.

Good luck!

How to export log from CISCOASA?like other cisco device logging 1.1.1.1 i want similar kind command in CISCO ASA


ASA's log is usualy stored localy on ASA itself, so easiest way to export that log is to go with telnet/ssh/console on it, do a command : show logging and copy/paste output into a new file.
but beware - this log is really short and as soon as ASA is rebooted - it's gone.
you could set asa to log to a syslog server (free on linux/freebsd or for windows use KIWI app).
that way all ASA log output is stored on pc/server running your syslog server.

Restart Cisco Asa 5510


Yes. The firewall will restart. Just be sure to save your running config to memory before turning off. For that you must issue the command: write memory.

Hello all can you please help me on how to restore the configuration of my ASA 5520? thanx


If you are going for factory reset use the following commands

asa>enable
asa#write erase
asa#reload

Dont save the configuration when it prompts for it.

if you want to restore the configuration from the backup

1. You need to have a TFTP server
2. Locate the config file on your TFTP server
3. TFTP server should be reachable from ASA

then

asa#copy tftp flash

give the tftp server ip address
give the configuration file name (as exactly on the TFTP server)

reload
