You must enable routing for the switch before you can route through any of the interfaces. The default value is disable. 2. Use ICMP Echo Replies to select enable or disable. If it is enable then only the router can send ECHO replies. By default ICMP Echo Replies are sent for echo requests. 3. Use ICMP Redirects to select enable or disable. If it is enabled globally and on interface level then only the router can send ICMP Redirects. 4. Use ICMP Rate Limit Interval to control the ICMP error packets by specifying the number of ICMP error packets that are allowed per burst interval. By default, Rate limit is 100 packets/sec i.e., burst interval is 1000 msec. To disable ICMP Rate limiting, set this field to '0'. Valid Rate Interval must be in the range 0 to 2147483647. 5. Use ICMP Rate Limit Burst Size to control the ICMP error packets by specifying the number of ICMP error packets that are allowed per burst interval. By default, burst size is 100 packets. When burst interval is 0 then configuring this field is not a valid operation. Valid Burst Size must be in the range 1 to 200. Table 7.
