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

12.3Configuration Example – IP ACL, DHCP Snooping, ARP Inspection, BPDU Filtering, and Source Guard

Figure 4: IP ACL, DHCP Snooping, ARP Inspection, and Source Guard

Overall, we wish to accomplish the following in regards to VLAN 110:

•Only allow ICMP and DHCP traffic to the DHCP server (172.30.30.50) and deny all other traffic to the 172.x.x.x network

•For the 10.x.x.x network, only allow access to the local network (10.62.32.0/24) and to the 10.10.30/0/24 network for full access to the internet

•Enable DHCP Snooping, ARP-Inspection, and

In regards to VLAN 220, we wish to accomplish the following:

•Allow full access to the core network 172.0.0.0/8 and 10.0.0.0/8

•Only allow only ICMP, HTTP and HTTPS traffic to the internet
