Using The Bulk Statistics Formatter; Setting Remote Filenames - Juniper SYSTEM BASICS - CONFIGURATION GUIDE V 11.1.X Configuration Manual

In RFC 1213 mode, interface creations should not result in gaps in the ifIndex range.
A gap that results from the deletion of an interface is acceptable because it is handled
by older network management applications. The gaps are eliminated after the router
is rebooted. However, in the default interface numbering mode, large gaps occur
from the creation of interfaces due to the use of the upper 8 bits of the ifIndex for
interface type encoding. Gaps are not eliminated after a system reboot.
In RFC 1213 mode, small gaps can occur in the creation of IP interfaces when virtual
routers are used. These gaps are minimized but not eliminated when the router is
rebooted.
Rather than seeing an ifIndex value of 1 and 10066329, for example, a management
client would see ifIndex values of 1 and 2.

Using the Bulk Statistics Formatter

The bulk statistics formatter allows you to set a remote filename dynamically and
specify the format for the end of each line in the bulkstats file.

Setting Remote Filenames

The router supports the following special characters for remote filenames:
The % variables in the remote name are replaced at runtime with the sysName and
sysUpTime parameters to produce variable filenames on the remote host.
See the bulkstats receiver remote-name command.
Use to enable the RFC 1213 interface numbering mode on bulkstats.
Example
host1(config)#bulkstats interfaces rfc 1213
Use the no version to disable the RFC 1213 interface numbering mode on
bulkstats.
See bulkstats interfaces rfc1213.
%x An integer in hexadecimal format (base 16)
%s A character string
%u An unsigned integer in decimal (base 10)
%d An integer in decimal (base 10)
