To confirm that the configuration is working properly:
Verifying That DHCP Snooping Is Working Correctly on Switch 1 on page 3103
Verifying That DAI Is Working Correctly on Switch 1 on page 3103
Verifying That MAC Limiting Is Working Correctly on Switch 1 on page 3104
Verifying That DHCP Snooping Is Working Correctly on Switch 1
Verify that DHCP snooping is working on Switch 1.
Send some DHCP requests from network devices (here they are DHCP clients) connected
to the switch.
Display the DHCP snooping information when the interface through which Switch 2 sends
the DHCP server replies to clients connected to Switch 1 is trusted. The server has provided
the IP addresses and leases:
user@switch1> show dhcp snooping binding

The output shows, for each MAC address, the assigned IP address and lease time—that
is, the time, in seconds, remaining before the lease expires.
Verifying That DAI Is Working Correctly on Switch 1
Verify that DAI is working on Switch 1.
