  3. Type the maximum number of hops away a BootP server can be located from a Layer 3 switch and still be used by the router clients for network booting in the BOOTP Relay Maximum Hop field. The range is from 1 through 15. The default value is 4 hops.
  4. Type the amount of time the device should keep a MAC address learned through ARP in the device ARP cache in the ARP Age (Minutes) field. The range is from 0 through 240 minutes. The default is 10 minutes.
  5. Type the maximum number of Layer 3 switches (hops) through which a packet can pass before being discarded in the TTL field. The range is from 1 through 255 hops. The default is 64 hops.
  6. Type the Layer 3 switch identifier in the Router ID field.
  7. Click Disable or Enable for IRDP . By default, this protocol is disabled.

    ICMP Router Discovery Protocol (IRDP) is an IP protocol a Layer 3 switch can use to advertise the IP addresses of its interfaces to the directly attached hosts.

  8. Click Disable or Enable for Load Sharing . If you click Enable , type the number of load sharing paths in the # of Paths field.
  9. Click Disable or Enable for Proxy ARP .

    Proxy ARP is an IP mechanism a Layer 3 switch can use to answer an ARP request on behalf of a host, by replying with the Layer 3 switch’s own MAC address instead of the host.

  10. Click Disable or Enable for RARP .

    Reverse ARP (RARP) is an IP mechanism a host can use to request an IP address from a directly attached Layer 3 switch when the host boots.

  11. Click Disable or Enable for Broadcast Forward .
  12. Click Disable or Enable for Directed Broadcast Forward .

    A directed broadcast is a packet containing all ones (or in some cases, all zeros) in the host portion of the destination IP address. When a Layer 3 switch forwards such a broadcast, it sends a copy of the packet to each of its enabled IP interfaces.

  13. Click Disable or Enable for Source Route .
  14. Click Disable or Enable for Access Control List .
  15. Click Apply .

    The message The change has been made is displayed. To reset the data entered in the configuration pane, click Reset .
