Prestige 2304 Support Notes

This configuration example shows you how to use a Generic Filter to block a specific MAC address of the LAN.

Before you Begin

Before you configure the filter, you need to know the MAC address of the client first. The MAC address can be provided by the NICs. If there is the LAN packet passing through the Prestige you can identify the uninteresting MAC address from the Prestige's LAN packet trace. Please have a look at the following example to know the trace of the LAN packets.

ras> sys trcp	channel enet0 bothway
ras> sys trcp	sw on
Now a client on the LAN is trying to ping Prestige………
ras> sys trcp	sw off
ras> sys trcp	disp
