IPv6 Configuration Guide K/KA/KB.15.15

bucket-size
This optional keyword specifies the maximum number of tokens allowed in the
token bucket at any time. Decreasing this value decreases the maximum number
of tokens that may be available at any time.
Default : 10; Range: 1 - 200
You can change the rate at which ICMP messages are allowed by changing the
error-interval with or without a corresponding change in the bucket-size.
The no ipv6 icmp error-interval command resets both the
error-interval and the bucket-size values to their defaults.
Use the show run command to view the current ICMP error interval settings.
For example, the following command limits ICMP error and informational messages to no more
than 20 every 1 second:
Switch(config)# ipv6 icmp error-interval 1000000 bucket-size 20
Ping for IPv6 (Ping6)
The Ping6 test is a point-to-point test that accepts an IPv6 address or IPv6 host name to see if an
IPv6 switch is communicating properly with another device on the same or another IPv6 network.
A ping test checks the path between the switch and another device by sending IP packets (ICMP
Echo Requests).
To use a ping6 command with an IPv6 host name or fully qualified domain names, see “DNS
Resolver for IPv6” (page 281).
You can issue single or multiple ping tests with varying repetitions and timeout periods to wait for
a ping reply.
Replies to each ping test are displayed on the console screen. To stop a ping test before it finishes,
press [Ctrl] [C].
For more information about using a ping test, see the “Troubleshooting” appendix in the current
Management and Configuration Guide for your switch.
Syntax
ping6 [ ipv6-address | hostname | switch-number ] [ repetitions 1 - 10000
] [ timeout 1 - 60 ] [ data-size 0 - 65507 ] [ data-fill 0 - 1024 ] [ source
[ ipv6-addr | vid ]] [ oobm ]
Syntax
ping6 [ link-local-address %vlan vid | hostname | switch-number ] [
repetitions 1 - 10000 ] [ timeout 1 - 60 ] [ data-size 0 - 65507 ] [
data-fill 0 - 1024 ] [ source [ ipv6-addr | vid ]] [ oobm ]
Pings the specified IPv6 host by sending ICMP version 6 (ICMPv6) echo request
packets to the specified host.
ipv6-address
IPv6 address of a destination host device.
link-local-address %vlan vid
IPv6 link-local address, where %vlan vid specifies the VLAN ID number.
hostname
Host name of an IPv6 host device configured on an IPv6 DNS server.
switch-number
Number of an IPv6-based switch that is a member of a switch stack (IPv6 subnet).
Valid values: 1 - 16.
