rate-limit command on the ISR4431 with K9 IOS Version 16.8.1
On my 1921 with IOS 15.4 I use the following command to protect my input Internet facing interface from ICMP flooding:
interface GigabitEthernet0/0 description XXXXXXXtel Broadband WAN FiberLink ip address A.B.C.D 255.255.255.252 ip access-group FilteredList in no ip redirects no ip unreachables ip flow ingress ip flow egress ip nat outside ip virtual-reassembly in rate-limit input access-group 101 8000 4400 4496 conform-action transmit exceed-action drop ip tcp adjust-mss 576 duplex full speed 100 crypto map tnsgmap
access-list 101 permit icmp any any echo access-list 101 permit icmp any any echo-reply access-list 112 permit ip host 192.168.111.199 any
Problem is, the rate-limit command is not present in IOS 16.8. If you look below at the appropriate section of the ? output:
port-tagging Allow port tagging on an interface pppoe pppoe interface subcommands pppoe-client pppoe client pppoe-sessions Configure pppoe per-interface options punt-control punt configuration rpl Configure RPL protocol rrr MPLS Traffic Engineering interface configuration commands sap-priority Assign a priority group service Configure Ether Service service-insertion Service-insertion AppNav Controller service-policy Configure CPL Service Policy service-routing Service Routing in Interface Mode shutdown Shutdown the selected interface smrp Simple Multicast Routing Protocol interface subcommands sna SNA pu configuration snapshot Configure snapshot support on the interface snmp Modify SNMP interface parameters source Get config from another source spanning-tree Spanning Tree Subsystem
Its not there.
So How can I do ICMP input rate limiting on the input of my Internet facing interface on IOS 16.8?
