NETGEAR 8800 Chassis Switch CLI Manual Default Disabled. Usage Guidelines This option only applies to the switch when the switch is not in routing mode. If the switch has a route to a destination network, the switch uses that router as the gateway to forward the packets to. If that router knows about a better route to the destination, and the next hop is in the same subnet as the originating router, the second router sends an ICMP redirect message to the first router. If ICMP useredirects is disabled, the switch disregards these messages and continues to send the packets to the second router. Example The following command disables the changing of routing table information: disable icmp useredirects disable iparp checking disable iparp {vr } checking Description Disable checking if the ARP request source IP address is within the range of the local interface or VLAN domain. Syntax Description vr_name Specifies a virtual router. Default Enabled. Usage Guidelines If you do not specify a virtual router, the command applies to the current virtual router. Example The following command disables IP ARP checking: disable iparp checking disable iparp refresh disable iparp {vr } refresh 852 | Chapter 19. IP Unicast Commands
