The following example displays the interfaces configured with IP Source Guard:
DellEMC> show ip dhcp snooping source-address-validation
ip sav access-list on TenGigabitEthernet 1/1
Total cam count 3
permit host 0.0.0.0 count (0 packets)
permit host 10.1.1.252 count (0 packets)
permit host 10.1.1.253 count (0 packets)
ipmac-vlan sav access-list on TenGigabitEthernet 1/2
Total cam count 4
permit host 0.0.0.0 host 00:00:00:00:00:00 count (0 packets)
permit vlan 10 host 10.1.1.1 host 00:00:00:aa:00:01 count (0 packets)

permit vlan 20 host 10.2.2.2 host 00:00:00:aa:00:04 count (0 packets)
The following example displays the port channel interfaces configured with IP Source Guard:
DellEMC> show ip dhcp snooping source-address-validation interface
portchannel 10
ipmac-vlan sav access-list on Port-channel 10 on stack-unit 0
Total cam count 5
permit host 0.0.0.0 host 00:00:00:00:00:00 count (0 packets)
permit vlan 10 host 1.1.1.1 host 00:00:00:00:01:01 count (0 packets)
permit vlan 10 host 1.1.1.2 host 00:00:00:00:01:02 count (0 packets)
permit vlan 10 host 1.1.1.3 host 00:00:00:00:01:03 count (0 packets)
ipmac-vlan sav access-list on Port-channel 10 on stack-unit 1
Total cam count 5
permit host 0.0.0.0 host 00:00:00:00:00:00 count (0 packets)
permit vlan 10 host 1.1.1.1 host 00:00:00:00:01:01 count (0 packets)
permit vlan 10 host 1.1.1.2 host 00:00:00:00:01:02 count (0 packets)
permit vlan 10 host 1.1.1.3 host 00:00:00:00:01:03 count (0 packets)
ipmac-vlan sav access-list on Port-channel 10 on stack-unit 2
Total cam count 5
permit host 0.0.0.0 host 00:00:00:00:00:00 count (0 packets)
permit vlan 10 host 1.1.1.1 host 00:00:00:00:01:01 count (0 packets)
permit vlan 10 host 1.1.1.2 host 00:00:00:00:01:02 count (0 packets)
permit vlan 10 host 1.1.1.3 host 00:00:00:00:01:03 count (0 packets)
NOTE: The output for port-channel interfaces does not display the physical interface.
The following example displays the SAV discard counters on all interfaces:
DellEMC> show ip dhcp snooping source-address-validation discard-
counters
deny access-list on TenGigabitEthernet 1/1
Total cam count 1
deny count (0 packets)
deny access-list on TenGigabitEthernet 1/2
Total cam count 2
deny vlan 10 count (0 packets)
deny vlan 20 count (0 packets)
The following example displays the SAV discard counters on a particular interface:
DellEMC> show ip dhcp snooping source-address-validation discard-
counters interface TenGigabitEthernet 1/1
deny access-list on TenGigabitEthernet 1/1
Total cam count 2
deny vlan 10 count (0 packets)
deny vlan 20 count (0 packets)
