Filters and QoS Configuration for ERS 5500
Technical Configuration Guide	v2.0	NN48500-559

ERS5500-24T#show ip dhcp-snooping interface 3-6,8-10

Result:

DHCP

Port Snooping

---- --------

3Untrusted

4Untrusted

5Untrusted

6Untrusted

8Untrusted

9Untrusted

10Untrusted

Step 3 – To view the DHCP-Snoop binding, enter the following command, assuming we have port member on ports 6 and 9

ERS5500-24T#show ip dhcp-snooping binding

Result:

MAC	IP	Lease (sec)	VID	Port
---------------------------------------------------------------
00-50-8b-e1-58-e8	10.62.32.10	691200	110	6
00-02-a5-e9-00-28	10.13.196.10	691200	220	9
Total Entries: 2

12.3.2.2 Verify ARP Inspection

Step 1 – Verify that ARP Inspection is enabled for VLAN’s 110 and 220

ERS5500-24T#show ip arp-inspection vlan

Result:

ARP

VLAN Inspection

--------------

1 Disabled

99 Disabled

110 Enabled

220 Enabled

700 Disabled

Step 2 – Verify all the access ports are configured for ‘untrusted’ – this is the default setting

ERS5500-24T#show ip arp-inspection interface 3-6,8-10

Result:

ARP

Port Inspection

---- ----------

3Untrusted

4Untrusted

5Untrusted

6Untrusted

8Untrusted

9Untrusted

10Untrusted
