DHCP Relay Settings Note: IP Forwarding must be enabled if a DHCP client uses unicast (instead of broadcast) to communicate with a DHCP server. Server #1 IP Address Server #2 IP Address The IP address of the first DHCP server to send DHCP requests to, when DHCP Relay mode is enabled.

DHCP Commands Go to DHCP Commands to view CLI commands which correspond to the web page entries described above. IP Filter IP filters (also called a rule set) act as a firewall to allow or deny an individual MAC address or individual or a range of IP addresses, ports, and protocols. When a network connection is configured to use an IP filter, all network traffic through that connection is compared, in order, to the rules of that filter. Network traffic may be allowed to pass, it may be dropped (without notice), or it may be rejected (sends back an error packet) depending upon the rules of that filter rule set. The administrator uses the Network > IP Filter page to view, add, edit, delete, and map IP filters. Warning: IP filters configuration is a feature for advanced users. Adding and enabling IP filter sets incorrectly can disable access to your SLC unit. Viewing IP Filters You can view a list of filters and a table showing how each filter is mapped to an interface. To view a list of IP filters: 1. Click the Network tab and select the IP Filter option. The following page displays: SLC™ 8000 Advanced Console Manager User Guide 92
