If you select Enable, then only the router can send ECHO replies. By default ICMP echo
replies are sent for echo requests.
8. 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.
9. 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, the rate limit is 100 packets/sec, (the burst interval is 1000 msec). To disable
ICMP Ratelimiting set this field to 0. The valid rate interval is in the range 0 to
2147483647.
10. 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, the burst size is 100 packets. When the burst interval is 0, then configuring
this field is not a valid operation. The valid burst size is 1 to 200.
11. Use Select to Configure Global Default Gateway to edit the Global Default Gateway field.
12. Use Global Default Gateway to set the global default gateway to the manually configured
value.
A default gateway configured with this command is more preferred than a default
gateway learned from a DHCP server. Only one default gateway can be configured. If you
invoke this command multiple times, each command replaces the previous value.
13. Click the Apply button.
The updated configuration is sent to the switch. Configuration changes take effect
immediately.
The following table describes the nonconfigurable information displayed on the page.
