Configuring Ipv6 Icmp Rate Limiting; Displaying Ipv6 - Cisco Catalyst 2360 Software Configuration Manual

Displaying IPv6

Use the no ipv6 nd router-preference interface configuration command to disable an IPv6 DRP.
This example shows how to configure a DRP of high for the router on an interface.
Switch# configure terminal
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# ipv6 nd router-preference high
Switch(config-if)# end
For more information about configuring DRP for IPv6, see the "Implementing IPv6 Addresses and Basic
Connectivity" chapter in the Cisco IOS IPv6 Configuration Library on Cisco.com.

Configuring IPv6 ICMP Rate Limiting

ICMP rate limiting is enabled by default with a default interval between error messages of 100
milliseconds and a bucket size (maximum number of tokens to be stored in a bucket) of 10.
Beginning in privileged EXEC mode, follow these steps to change the ICMP rate-limiting parameters:
Command
Step 1 configure terminal
Step 2 ipv6 icmp error-interval interval [bucketsize]
Step 3 end
Step 4 show ipv6 interface [interface-id]
Step 5 copy running-config startup-config
To return to the default configuration, use the no ipv6 icmp error-interval global configuration
command.
This example shows how to configure an IPv6 ICMP error message interval of 50 milliseconds and a
bucket size of 20 tokens.
Switch(config)#ipv6 icmp error-interval 50 20

shows the privileged EXEC commands for monitoring IPv6 on the switch.
Purpose
Enter global configuration mode.
Configure the interval and bucket size for IPv6 ICMP error
messages:
interval—The interval (in milliseconds) between tokens
•
being added to the bucket. The range is from 0 to
2147483647 milliseconds.
bucketsize—(Optional) The maximum number of tokens
•
stored in the bucket. The range is from 1 to 200.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
