Etherlike Statistics on ESW2-350G Switches
Etherlike statistics are related to errors at the physical layer such as hardware related errors. These errors can occur due to failure in essential network components such as copper cables, interfaces, and Network Interface Cards (NICs). In case of a connectivity problem, these statistics can be helpful in determine the cause of the problem in the physical layeer. The article explains etherlike statistics per port and its configuration on ESW2 350G Series Managed Switches.
• ESW-350G Series Switches
Step 1. Log in to the web configuration utility and choose Status and Statistics > Etherlike. The Etherlike page opens:
Step 2. Enter the parameters.
• Interface—Select the type of interface and specific interface (Port Numbers) for which Ethernet statistics are to be displayed.
• Refresh Rate—Select the amount of time that passes before the Etherlike statistics are refreshed.
The available options are:
• No Refresh : The Etherlike page never refreshes.
• 15 sec : Refreshes the Etherlike page every 15 seconds.
• 30 sec : Refreshes the Etherlike page every 30 seconds.
• 60 sec : Refreshes the Etherlike page every 60 seconds.
Step 3. The below mentioned fields are displayed for the selected interface
• Frame Check Sequence (FCS) Errors: are the number of received frames that failed the Cyclic Redundancy Checks.
• Single Collision Frames: are the number of frames that were involved in a single collision,but were successfully send out.
• Late Collisions: are the Collisions that have been identified after the first 512 bits of data.
• Excessive Collisions: are the Number of transmissions discarded due to excessive collisions.
• Oversize Packets: are the number of Packets greater than 2000 octets received.
• Internal MAC Receive Errors: displays the number of Frames discarded because of receiver errors.
• Pause Frames Received: are the number of received flow control pause frames.
• Pause Frames Transmitted: are number of flow control pause frames sent out from the selected interface.
Step 4 . To clear the Etherlike statistics counters on the chosen interface click Clear Interface Counters, or if you want to clear the Etherlike statistics counters on all the interfaces click Clear All Interface Counters.
