Configuring policy
When a packet exits the G250/G350 through an interface, the G250/G350 applies the policy
lists in the following order:
1. Apply the Egress Access Control List.
If the Egress Access Control List does not drop the packet:
2. Apply the Egress QoS List.
3. The packet exits the G250/G350 through the interface.

G350 applies policy lists to packets.

You can configure which policy lists are attached to each interface. You can choose the Ingress
Access Control List and the Egress Access Control List from among the access control lists that
are configured on the G250/G350. You can choose the Ingress QoS List and the Egress QoS
List from among the QoS lists that are configured on the G250/G350.
To attach an access control list to an interface as its Ingress Access Control List, enter the
interface context and type ip access-group list number in. To attach an access control
list to an interface as its Egress Access Control List, enter the interface context and type ip
access-group list number out.
To attach a QoS list to an interface as its Ingress QoS List, enter the interface context and type
ip qos-group list number in. To attach an access control list to an interface as its
Egress QoS List, enter the interface context and type ip qos-group list number out.
For example, the following sequence of commands attach policy lists to the VLAN 2 interface.
Access control list 301 becomes the Ingress Access Control List for VLAN 2. QoS list 401
becomes the Egress QoS List for VLAN 2.
G350-001# interface Vlan 2
G350-001(if:Vlan 2)# ip access-group 301 in
Done!
G350-001(if:Vlan 2)# ip qos-group 401 out
Done!
