Chapter 25 Bandwidth Management Table 133 Configuration > Bandwidth Management LABEL To Source Destination DSCP Marking DESCRIPTION This is the destination zone of the traffic to which this policy applies. This is the source address or address group for whom this policy applies. If any displays, the policy is effective for every source. This is the destination address or address group for whom this policy applies. If any displays, the policy is effective for every destination. This is how the ISG50 handles the DSCP value of the outgoing packets that match this policy. In - Inbound, the traffic the ISG50 sends to a connection's initiator. Out - Outbound, the traffic the ISG50 sends out from a connection's initiator. If this field displays a DSCP value, the ISG50 applies that DSCP value to the route's outgoing packets. preserve means the ISG50 does not modify the DSCP value of the route's outgoing packets. default means the ISG50 sets the DSCP value of the route's outgoing packets to 0. BWM The "af" choices stand for Assured Forwarding. The number following the "af" identifies one of four classes and one of three drop preferences. See Assured Forwarding (AF) PHB for DiffServ on page 299 for more details. These fields show the amount of bandwidth the traffic can use. In - This is how much inbound bandwidth, in kilobits per second, this policy allows the matching traffic to use. Inbound refers to the traffic the ISG50 sends to a connection's initiator. If no displays here, this policy does not apply bandwidth management for the inbound traffic. Out - This is how much outgoing bandwidth, in kilobits per second, this policy allows the matching traffic to use. Outbound refers to the traffic the ISG50 sends out from a connection's initiator. If no displays here, this policy does not apply bandwidth management for the outbound traffic. Apply Reset Pri - This is the priority for the traffic that matches this policy. The smaller the number, the higher the priority. Traffic with a higher priority is given bandwidth before traffic with a lower priority. The ISG50 ignores this number if the incoming and outgoing limits are both set to 0. In this case the traffic is automatically treated as being set to the lowest priority (7) regardless of this field's configuration. Click Apply to save your changes back to the ISG50.
