The enhanced forwarding function of control packets generated by the device has been enabled using the ip soft-forward enhance enable command. After the undo control-packet output filter bypass command is executed, the device is configured to discard generated control packets when the traffic policy and ACL-based simplified traffic policy contain the deny action and apply QoS policy to the control packets to meet different service requirements. For example, if BGP packets, ICMP packets, IGMP packets, OSPF packets, PIM packets, RIP packets, SNMP packets, SSH packets, and UDP packets generated by the device are configured not to support traffic policing function, the device generates the configuration files of the undo control-packet telnet other-protocols output car bypass commands.Īfter the enhanced forwarding function is enabled for the control packets generated by the device, the device does not discard the control packets when the traffic policy and ACL-based simplified traffic policy contain the deny action. If the control-packet output queue bypass command is then executed to configure a specified type of control packets generated by the device not to support traffic policing function, the device does not generate the configuration file of the undo control-packet all output car bypass command but generates the configuration files of the control packets that are configured to support traffic policing function.
When bgp, icmp, igmp, ospf, pim, rip, snmp, ssh, telnet, udp, and other-protocols are specified in the undo control-packet output car bypass commands, the device generates a configuration file of the undo control-packet all output car bypass command. In versions earlier than V200R005C00, if the ip soft-forward enhance enable command has been executed to enable the enhanced forwarding function on the device, the device generates the configuration file of the undo control-packet all output car bypass command after the device is upgraded to V200R005C00. For details about traffic policing configuration, see Configuring Traffic Policing in NetEngine AR Configuration Guide-QoS.Ĭonfiguring control packets generated by the device to support traffic policing function may cause control packets to be discarded and affect user services. The enhanced forwarding function of the control packets generated by the device has been enabled using the ip soft-forward enhance enable command.Īfter control packets generated by the device are configured to support traffic policing function, configure QoS policies to process different control packets. After the enhanced forwarding function of the control packets generated by the device is enabled, you can run the undo control-packet output car bypass command to configures control packets generated by the device to support traffic policing function to apply QoS policies to different control packets.
