Display DHCPv4 Relay Information

You can use show commands to display information about DHCP relay statistics, relay addresses for a device, and relay addresses for an interface.

1. Access privileged EXEC mode on a device where DHCP relay is configured.
2. Display statistics such as the number of client packets and the number of dropped server packets for the device.
   

   device# show ip dhcp relay statistics
   
   Address   Disc.   Offer  Req.   Ack   Nak   Decline     Inform
   -------   -----   -----  ----   ---   ---   -------     ------
   2.3.4.5     300     100  1211  1201     0         0         0        
   10.0.1.2    300     100  1211  1207     0         0         0        
   
   Client Packets: 2701
   Server Packets: 2932
   Client Packets Dropped: 0
   Server Packets Dropped: 0

3. Display all DHCP relay addresses configured on the device.
   

   device# show ip dhcp relay address
   DHCP Relay Information Option: Enabled
   
   ---------                     -------------                 --------
   Interface                     Relay Address                 VRF Name
   ---------                     -------------                 --------
   eth1/18                       105.0.0.10                    default-vrf
   eth1/18                       107.0.0.1                     default-vrf
   ve 200                        107.0.0.1                     default-vrf

4. Display all DHCP relay addresses configured for a specific interface on the device.
   

   device# show ip dhcp relay address interface ethernet 1/18
   DHCP Relay Information Option: Enabled
   DHCP Remote ID (Type:Length:Vlan:Mac): 00:08:0000:000000f8003e
   ---------                     -------------                 --------
   Interface                     Relay Address                 VRF Name
   ---------                     -------------                 --------
   eth 1/18                       105.0.0.10                    default-vrf
   eth 1/18                       107.0.0.1                     default-vrf

   This example displays addresses configured on interface 1/18.

   

   device# show ip dhcp relay address interface ve 200
   DHCP Relay Information Option: Enabled
   DHCP Remote ID (Type:Length:Vlan:Mac): 00:08:0000:000000f8003d
   ---------                     -------------                 --------
   Interface                     Relay Address                 VRF Name
   ---------                     -------------                 --------
   ve 200                         107.0.0.1                     default-vrf

   This example displays addresses configured on VE 200.
