3.2.2 Configuring Null Interfaces

Points to note

The example below shows how to set the null interface to discard the packets sent to a specific network or terminal via the Switch.

Command examples

1. (config)# interface null 0

   Sets the null interface.

2. (config)# ip route 10.0.0.0 255.0.0.0 null 0

   Specifies the null interface as the next hop of static route 10.0.0.0/8. When the packets sent to this network pass through the Switch, the packets are not forwarded and instead are sent to the null interface for discarding.
