Preservation of Statistics During Stateful Line Module Switchover

PPP Accounting Statistics

Copyright © 2010, Juniper Networks, Inc.
The following log messages are displayed for SRP modules and line modules when
stateful switchover is disabled for those modules. Any failure or restart of the secondary
line module causes high availability to move to the disabled state.
CRITICAL 12/16/2003 00:03:39 os (): Standby SRP has assumed the role of Active SRP
(cold restart)
WARNING 12/15/2003 23:34:23 os (): Line card in slot X has cold-restarted.

Statistical details associated with PPP and policy manager applications are retained
across a stateful line module switchover. All other counters for settings and parameters
connected with other applications running on the router are reset to zero after the
switchover occurs to the new primary module. The following sections describe details
on the statistics polling process and the attributes that are maintained after a stateful
line module switchover:
For each PPP subscriber, accounting statistics are polled and collected every 10 minutes.
These statistics are synchronized with the secondary line module. The statistical details
collected just before the switchover represent the baseline for statistics on the newly
configured primary module. At a maximum, statistics that accumulate for about 10
minutes might be lost and not synchronized with the new primary module. This scenario
occurs when polling was to happen and the primary module switched over to the
secondary module, just before polling commenced. The JunosE software begins the
collection of accounting statistics for terminated PPP sessions following, but not including,
authentication acknowledgement from the E120 and E320 router. The acknowledgment
is either a CHAP success or PAP acknowledgement packet. The following PPP statistics
are retained across the stateful line module switchover:
Number of IPv4 octets received from the interface (Acct-Input-Octets, RADIUS attribute
42)
Number of IPv4 octets transmitted to the interface (Acct-Output-Octets, RADIUS
attribute 43)
Number of IPv4 packets received from the interface (Acct-Input-Packets, RADIUS
attribute 47)
Number of IPv4 packets transmitted to the interface (Acct-Output-Packets, RADIUS
attribute 48)
Number of IPv6 octets received from the interface (Ipv6-Acct-Input-Octets, RADIUS
attribute 26-151)
