Configuring IPv6 ICMP
• The interval at which tokens are added to the bucket. The default is 100 milliseconds.
• The maximum number of tokens in the bucket. The default is 10 tokens.
For example, to adjust the interval to 1000 milliseconds and the number of tokens to 100 tokens,
enter the following command.
Brocade(config)# ipv6 icmp error-interval 1000 100
Syntax: [no] ipv6 icmp error-interval interval [number-of-tokens]
The interval at which tokens are placed in the bucket has a range of 0 – 2147483647 milliseconds.
NOTE
If you keep the default interval (100 milliseconds), output from the show run command does not
show the setting of the ipv6 icmp error-interval command. In addition, if you configure the interval
value to a number that does not evenly divide into 100000 (100 milliseconds), the system rounds
the value up to the next higher value that does divide evenly. For example, if you specify an interval
value of 150, the system rounds it to 200.
ICMP rate limiting is enabled by default. To disable ICMP rate limiting, set the interval to 0.
Enabling ICMP redirect messages
To enable ICMP redirect messages, you need to configure icmp redirect at both global level and the
interface level. You can enable or disable a device to transmit ICMP redirect messages from a
global level and the interface level.
To enable the ICMP redirect messages from global level, enter the following commands.
Syntax: [no] ipv6 icmp redirects
By default, IPv6 redirect is disabled and the device does not send an ICMP redirect message to a
neighboring host to inform it of a better first-hop device on a path to a destination. (For more
information about how ICMP redirect messages are implemented for IPv6, refer to
“Configuring
IPv6 neighbor discovery” on page 443.)
To enable the sending of ICMP redirect messages on interface 3/1, enter the following commands.
Brocade(config)# interface ethernet 3/1
Brocade(config-if-e100-3/1)# ipv6 redirects
To disable the ICMP redirect messages from Ethernet interface 3/1, enter the following commands.
Brocade(config)# interface ethernet 3/1
Brocade(config-if-e100-3/1)# no ipv6 redirects
Syntax: [no] ipv6 redirects
Use the show ipv6 interface interface port-number command to verify that the sending of ICMP
redirect messages is enabled on a particular interface.
