Configuring policyDevice-wide policy listsYou can attach a policy list (other than a policy-based routing list) to every interface on the G350using one command. To do this, attach a list to the Loopback 1 interface. For more information,see Attaching policy lists to an interface on page 258.Note:Note: If you attach a policy list to a Loopback interface other than Loopback 1, thepolicy list has no effect.When you attach a policy list to the Loopback 1 interface, thereby creating a device-wide policylist, and you also attach policy lists to specific interfaces, the G350 applies the lists in thefollowing order:●●Incoming packets:a. Apply the ingress policy lists that are attached to the interface.b. Apply the device-wide ingress policy lists.Outgoing packets:a. Apply the device-wide egress policy lists.b. Apply the egress policy lists that are attached to the interface.Defining global rulesIn an access control list, you can define global rules for packets that contain IP fragments and IPoptions. These rules apply to all packets. This is in contrast to individual rules, which apply topackets that match certain defined criteria. See Defining rules on page 261.The G350 applies global rules before applying individual rules.To define a global rule:1. Enter the context of the access control list in which you want to define the rule.2. Enter one of the following commands, followed by the name of a composite command:- ip-fragments-in — applies to incoming packets that contain IP fragments- ip-fragments-out — applies to outgoing packets that contain IP fragments- ip-options-in — applies to incoming packets that contain IP options- ip-options-out — applies to outgoing packets that contain IP options260 Administration of the Avaya G350 Media Gateway
