Monitoring IPv6 and Neighbor Discovery

This section shows how to set an IPv6 statistics baseline and use the show commands to view your IPv6 configuration, monitor IPv6 interfaces and statistics, and view IPv6 neighbors.

System Event Logs

To troubleshoot and monitor IPv6, use the following system event logs:

ipv6General - IPv6 general information
ipv6Interface - IPv6 interface events
ipv6ProfileMgr - IPv6 profile manager events
ipv6RouteTable - IPv6 routing table events
ipv6Traffic - IPv6 frame transmit and receive events

For more information on using event logs, see JUNOSe System Basics Configuration Guide, Chapter 12, Logging System Events.

Establishing a Baseline

IPv6 statistics are stored in system counters. The only way to reset the system counters is to reboot the system. You can, however, establish a baseline for IPv6 statistics by setting a group of reference counters to zero.

baseline ipv6

Sets a baseline for IPv6 statistics.
The router implements the baseline by reading and storing the statistics at the time the baseline is set and then subtracting this baseline whenever baseline-relative statistics are retrieved.
Use the udp keyword to set a baseline for UDP statistics
Use the delta keyword with IPv6 show commands to specify that baselined statistics are to be shown.
Example

host1#baseline ipv6

There is no no version.

baseline ipv6 interface

Use to set a statistical baseline for a specified IPv6 interface.
Example

host1#baseline ipv6 interface atm 2/0.100

There is no no version.

IPv6 show Commands

You can monitor the following aspects of IPv6 using show ipv6 commands:



 To Display
 Command

 General IPv6 information

 show ipv6


 IPv6 addresses

 show ipv6 address


 IPv6 Interfaces

 show ipv6 interface


 IPv6 neighbors

 show ipv6 neighbors

To Display	Command
General IPv6 information	show ipv6
IPv6 addresses	show ipv6 address
IPv6 Interfaces	show ipv6 interface
IPv6 neighbors	show ipv6 neighbors
IPv6 profile information	show ipv6 profile
Active IPv6 protocol information	show ipv6 protocols
IPv6 route redistribution configuration	show ipv6 redistribute
IPv6 routes	show ipv6 route
IPv6 router advertisements received	show ipv6 routers
IPv6 static routes	show ipv6 static
IPv6 statistics/traffic	show ipv6 traffic
IPv6 UDP information	show ipv6 udp statistics

You can use the output filtering feature of the show command to include or exclude lines of output based on a text string that you specify. See JUNOSe System Basics Configuration Guide, Chapter 2, Command Line Interface, for details.

show ipv6

Use to display general IPv6 information.
Example

host1#show ipv6

 Ipv6 Unicast Routing: Enabled

 Default hop limit: not specified

 Number of interfaces: 2

 Default interface source address/mask: fe80::90:1a00:210:fd0/128

show ipv6 address
show ipv6 interface

Use to display detailed or summary information for a particular IPv6 address or interface or for all interfaces.
The default for the show ipv6 interface command is all interface types and all interfaces.
Use brief or detail keywords with the show ipv6 interface command to display different levels of information.
