Configure Passwords

The SSR provides password authentication for accessing the User and Enable modes. If TACACS is not enabled on the SSR, only local password authentication is performed.

To configure SSR passwords, enter the following commands in Configure mode:

Set User mode password.

Layer-2 Security Filters

Layer-2 security filters on the SSR allow you to configure ports to filter specific MAC addresses. When defining a Layer-2 security filter, you specify to which ports you want the filter to apply. You can specify the following security filters:

•Address filters

These filters block traffic based on the frame's source MAC address, destination MAC address, or both source and destination MAC addresses in flow bridging mode. Address filters are always configured and applied to the input port.

•Port-to-address lock filters

These filters prohibit a user connected to a locked port or set of ports from using another port.

•Static entry filters

These filters allow or force traffic to go to a set of destination ports based on a frame's source MAC address, destination MAC address, or both source and destination MAC addresses in flow bridging mode. Static entries are always configured and applied at the input port.

•Secure port filters

A secure filter shuts down access to the SSR based on MAC addresses. All packets received by a port are dropped. When combined with static entries, however, these filters can be used to drop all received traffic but allow some frames to go through.
