What is total output drops on Cisco switch?
Total output drops: The number of packets dropped because the output queue is full. A common cause of this might be traffic from a high bandwidth link being switched to a lower bandwidth link or traffic from multiple inbound links being switched to a single outbound link.
What are unknown protocol drops?
“Unknown protocol drops are normally dropped because the interface where these packets are received is not configured for this type of protocol, or it can be any protocol that the router does not recognize.
What is queue limit in ns2?
Each node uses a DropTail queue that has a maximum size of 10.
What is weighted fair queuing Cisco?
WFQ automatically classifies packets based on flows, with each flow being placed into a separate queue. For WFQ purposes, a flow is defined as all packets with the same values for the following: ■ Source IP address. ■ Destination IP address.
What is excess defer frames?
Excess Defer frames: According to Cisco documentation it is the number of frames that are not sent after the time exceeds the maximum-packet time. It means that the port is under heavy load. The device connected to the port is transmitting or receiving more traffic that can be handled by the port.
How do I disable DTP?
There are two ways to disable DTP negotiation:
- Configure the interface for access mode.
- Use the switchport nonegotiate command on the interface.
What is CBR in network simulator?
CBR [Constant bit rate] is mainly used in networking streaming applications as content can be transferred through limited channel capacity. NS2 is one of the major simulator used today for networking applications. But how many of us have studied about NS2 completely, remains a challenging question.
What is Wred in QOS?
Weighted random early detection (WRED) is a queueing discipline for a network scheduler suited for congestion avoidance. It is an extension to random early detection (RED) where a single queue may have several different sets of queue thresholds. Each threshold set is associated to a particular traffic class.
What does WFQ stand for?
Weighted fair queueing (WFQ) is a method of automatically smoothing out the flow of data in packet-switched communication networks by sorting packets to minimize the average latency and prevent exaggerated discrepancies between the transmission efficiency afforded to narrowband versus broadband signals.
