Managed Switch CLI Manual, Release 8.0 Term Definition Maximum Hop The maximum allowable relay agent hops. Count Minimum Wait The minimum wait time. Time (Seconds) Admin Mode Indicates whether relaying of requests is enabled or disabled. Server IP Address The IP address for the BootP/DHCP Relay server. Circuit Id Option The DHCP circuit Id option which may be enabled or disabled. Mode Requests Received The number or requests received. Requests Relayed The number of requests relayed. Packets Discarded The number of packets discarded. IP Helper Commands This section describes the commands to configure a DHCP relay agent with multiple DHCP server addresses per routing interface, and to use different server addresses for client packets arriving on different interfaces on the relay agent. ip helper-address (Global Config) Use the Global Configuration ip helper-address command to have the switch forward User Datagram Protocol (UDP) broadcasts received on an interface. To disable the forwarding of broadcast packets to specific addresses, use the no form of this command. The ip helper-address command forwards specific UDP broadcast from one interface to another. You can define many helper addresses but the total number of address-port pairs is limited to 128 for the whole device. The setting of a helper address for a specific interface has precedence over a setting of a helper address for all interfaces. You cannot enable forwarding of BOOTP/DHCP packets (ports 67,68) with this command. If you want to relay BOOTP/DHCP packets, use the DHCP relay commands. Routing Commands v1.0, July 2009 4-27
