Input and Output Policy Actions

Table 18-2
OL-7433-09
The set qos-group (input only), set ip precedence, and set ip dscp policy map actions
–
The Cisco 10000 series router does not support the following QoS features when no atm pxf
queuing is enabled or the VC is a UBR VC:
Weighted fair queuing (WFQ)
–
Weighted random early detection (WRED)
–
Class-based weighted fair queuing (CBWFQ)
–
Traffic shaping for IP and PPP
–
For RBE sessions and VAIs that inherit the service policy of the VC, the Cisco 10000 series router
supports the following QoS features when atm pxf queuing is enabled and the VC is a VBR VC:
Rate limiting on each session in the input, output, or in both the input and output directions
–
The set qos-group (input only), set ip precedence, and set ip dscp policy map actions
–
Weighted fair queuing (WFQ)
–
Weighted random early detection (WRED)
–
Class-based weighted fair queuing (CBWFQ)
–
Traffic shaping
–
The Cisco 10000 series router has been verified to support a VC count up to 8000 VCs when
atm pxf queuing is enabled. The router supports ATM level QoS, affecting traffic on the ATM
VCs. Both UBR (PCR specified) and VBR (PCR and SCR specified) VCs are available.
The Cisco 10000 series router does not impose any restrictions on the classification definitions you
include in the class map. However, it does limit the input and output policy actions that you can
define in a policy map. These limitations are based on the type of interface on which you apply the
service policy. As indicated in
– Normal interface, including VBR VCs on ports configured in pxf queuing mode
– Tag interface (MPLS VPN)
Virtual access interface (VAI)
–
ATM UBR VCs and VCs configured on ports in no atm pxf queuing mode
–
lists the input policy actions that you can define in a policy map for specific interface types.
