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

12.3.2.3 Verify IP Source Guard

Step 1 – To view the IP Source Guard binding, enter the following command, assuming we have port member on ports 6 and 9

ERS5500-24T#show ip source binding

Result:

Port Address

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

610.62.32.10

910.13.196.10

&An IP source Guard or ARP Inspection event will be logged (local and remote if enabled) indicated by the message, i.e. from port 6: “ARP packet with invalid IP/MAC binding on un-trusted port 1/6”.

12.3.2.4 Verify ACL Configuration

Step 1 – To view the IP ACL configuration, enter the following command:

ERS5500-24T#show qos ip-acl
