Syntax
show ip helper statistics
Default Configuration
This command has no default configuration.
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.
