show ip helper statistics
Use the show ip helper statistics command to display the number of DHCP
and other UDP packets processed and relayed by the UDP relay agent.
Interface The relay configuration is applied to packets that arrive on this
interface. This field is set to “any” for global IP helper entries.
UDP Port The relay configuration is applied to packets whose destination
UDP port is this port. Entries whose UDP port is identified as
“any” are applied to packets with the destination UDP ports listed
in Table 4.
Discard If “Yes”, packets arriving on the given interface with the given
destination UDP port are discarded rather than relayed. Discard
entries are used to override global IP helper address entries which
otherwise might apply to a packet.
Hit Count The number of times the IP helper entry has been used to relay or
discard a packet.
Server Address The IPv4 address of the server to which packets are relayed.
