VIRTUALRACK for Network Engineers: notes: Policing
http://virtualrack.blogspot.com/2011/11/notes-policing.html
VIRTUALRACK for Network Engineers. This blog is all about networking technologies that drives the human network today. Welcome to the Human Network! Wednesday, November 9, 2011. Traffic-policing is designed to drop traffic in excess of the target rate, and enforce a max threshold of bandwidth. To accomplish this, a system of credits is used. Before a packet can be sent the amount of credits equaling the packet's size in bits must have been earned, like wages. Limits the rate of traffic on the interface.

VIRTUALRACK for Network Engineers. This blog is all about networking technologies that drives the human network today. Welcome to the Human Network! Monday, November 7, 2011. Only applies to outbound traffic. Queueing mechanisms can be used in conjunction with traffic shaping. Traffic shaping delay packets to ensure that a class of packets does not exceed a defined rate. While delaying the packets, the shaping function queues the packets, by default in a FIFO queue. 2 Types of Shaping. The Tc cannot be a...

VIRTUALRACK for Network Engineers: notes: Legacy Custom Queuing
http://virtualrack.blogspot.com/2011/11/notes-legacy-custom-queuing.html
VIRTUALRACK for Network Engineers. This blog is all about networking technologies that drives the human network today. Welcome to the Human Network! Thursday, November 3, 2011. Notes: Legacy Custom Queuing. Implementation of weighted round robin. Up to 16 configurable queues, including a priority queue. Thresholds are based on the number of bytes and/or number of packets. CQ is prone to inaccurate bandwidth allocations. Can only apply one mechanism per interface. MQC changes this. Byte-count = 1500 bytes.

VIRTUALRACK for Network Engineers: notes: QoS in Switches
http://virtualrack.blogspot.com/2011/11/cos-class-of-service-is-also-known-as.html
VIRTUALRACK for Network Engineers. This blog is all about networking technologies that drives the human network today. Welcome to the Human Network! Wednesday, November 16, 2011. Notes: QoS in Switches. COS (Class of Service), is also known as 802.1p priority bits. QOS must be enabled on a switch with "mls qos". With "mls qos" OFF the switch does not modify any markings. With "mls qos" ON switch clears all COS, ip-prec, and DCSP, unless the trust configuration was specified. Mls qos cos override. The wei...

January 25th, 2014. Your company has just added R3 router to the existing network. But currently no routing updates are being exchanged between R3 and the network. All other connectivity, including Internet access are working properly. The task is to identify the fault(s) and correct the router configuration to provide full connectivity between the routers. All passwords on all routers are set to cisco. IP addresses are listed in the chart below. You should check the AS numbers on other routers for sure).
