The WordPress polling application seems to be down at the moment, so I’ll unleash the first of the Friday Questions of the Day one day early:
Your co-worker has been tasked with limiting the amount of traffic inbound on interface fa0/0 from a device with the MAC address of 11-11-22-22-33-33 to 5Mbits/second. Your boss has just informed him that there is more than 20Mbits/second inbound on that port from the device with that MAC address. He turns to you and asks you to look at his configuration:
rate-limit input access-group 100 5000000 2500 2500 conform-action transmit exceed-action drop
access-list rate-limit 100 1111.2222.3333
Why are you receiving significantly more than 5Mbps inbound on interface f0/0 from the device with the MAC address of 1111.2222.3333?
Which of the following is NOT a shaping feature supported by Cisco IOS?
Here are the results:
|Flow-Based Traffic Shaping (FBTS)||64%|
|Generic Traffic Shaping (GTS)||16%|
|Frame Relay Traffic Shaping (FRTS)||2%|
The answer: Flow-Based Traffic Shaping (FBTS)
For traffic shaping, Cisco IOS QoS includes Generic Traffic Shaping (GTS),Class-Based Shaping, and Frame Relay Traffic Shaping (FRTS). These features allow you to regulate packet flow (that is, the flow of traffic) on your network.
