Security of a 2948G L2 switch outside of our immediate control.

Hi,

Can anyone tell me where to look for the syntax to apply an incoming acl

list on my 6509 switch and/or is there a way to syslog a particular port? I only have Sup1 module and do not have a Policy Feature Card. I do have a 8510 that does all of my Vlan routing.

The reason I am asking is that I will have a 2948G outside of my control with devices still being abled to connect to my Win NT network. I disabled local console/telnet connections including the enable ones, disabled ports which are not going to used and configured them with a null vlan information. I am also using Cisco Secure for authentication. We are wanting to be able to log if the device goes offline and don't want anyone to be able to recover the password via turning off the power and going through the password recovery methods.

Thanks,

Mitch

I am assuming your 6509 is running CatOS. You can use VACLs to access-control traffic entering a VLAN on Catalyst 6000 switches running CatOS. You can find more details at http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/sw_6_3/cmd_ref/setsn_su.htm#17780

However, VACLs require a Policy feature card (PFC) on the supervisor.

Configuring IP permit list would prevent un-authorized access to your CAT switches

http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/sw_6_3/confg_gd/ip_perm.htm

Make sure the config-register is 0x2102 which ignores break sequence.

But, If someone can physically connect to the console and do password recovery, you may have to secure the switch physically and there is nothing CISCO IOS can do.
