10-Gigabit Module
and Forwarding
Cache
Because of the volume of traffic that the 10-Gigabit module can process and
its internal architecture, the module can cause the number of entries in the
Layer 3 forwarding cache to reach the default maximum of 130,000 sooner
than other modules. Once the maximum is reached:
■
The switch routes all new traffic flows by means of the slow path.
■
The speed at which traffic is forwarded is decreased.
■
The role of master virtual router may be transferred from one VRRP
router to another if VRRP is enabled.
■
The following message is displayed in the CLI if debug mode is
enabled and in the event log if logging of CLI debug messages is
enabled:
Log entry
<number> by event 2 at <date and
time> : Normal(0)
Description: OS Error -- FILE: p2_ipenv.c
LINE: 752 Value 0x2 : IP timer got skewed
(Use the logging protocol event cli debug command to enable
logging of CLI debug messages.)
