Description
Specify disabling the control queue for all ports on the 10-Gigabit Ethernet LAN/WAN PIC. Deleting this configuration re-enables the control queue feature on all ports of the 10-Gigabit Ethernet LAN/WAN PIC.
For the 10-Gigabit Ethernet LAN/WAN PIC with SFP+ (model
number PD-5-10XGE-SFPP), the control queue has a rate limiter to limit
the control traffic to 2 Mbps (fixed, not user-configurable) per port.
If the transit control traffic crosses this limit, then it can cause
drops on locally terminating control traffic, causing flap of protocols
such as BGP and OSPF. To avoid the control traffic being dropped,
configure the no-pre-classifier statement to disable the
control queue.
Default
The no-pre-classifier statement is not configured
and the control queue is operational.
Required Privilege Level
