IP Helper Statistics Use the IP Helper Statistics page to view UDP Relay Statistics for the switch. To display the page, click Routing > IP Helper > Statistics in the tree view. Figure 9-27. IP Helper Statistics The IP Helper Statistics page contains the following fields: • DHCP Client Messages Received - The number of valid messages received from a DHCP client. The count is only increased if IP helper is enabled globally, the ingress routing interface is up, and the packet passes a number of validity checks, such as having a TTL >1 and having valid source and destination IP addresses. • DHCP Client Messages Relayed - The number of DHCP client messages relayed to a server. If a message is relayed to multiple servers, the count is increased once for each server. • DHCP Server Messages Received - The number of DHCP responses received from the DHCP server. This count only includes messages that the DHCP server unicasts to the relay agent for relay to the client. • DHCP Server Messages Relayed - Specifies the number of DHCP server messages relayed to a client. • UDP Client Messages Received - The number of valid UDP packets received. This count includes DHCP messages and all other protocols relayed. Conditions are similar to those for the first statistic in this table. • UDP Client Messages Relayed - The number of UDP packets relayed. This count includes DHCP messages relayed as well as all other protocols. The count is increased for each server to which a packet is sent. 506 Configuring Routing
