CRC Errors Counts otherwise valid frames that fail the CRC check Oversize Frames Counts frames longer than the 1518 byte octet limit set by the Ethernet standard This is likely caused by a software problem Using the Console Interface 49 Fragments Counts packets less than 64 bytes with either bad framing or an invalid CRC These are normally the result of collisions Jabber Frames Counts frames with length more than 1518 bytes and with CRC error or misaligned bad framing Collision Counts collisions on the Ethernet segment Late Collisions The number of collisions that occurred at or after the 64 byte octet in the frame Bytes Tx Counts the number of bytes successfully sent from the port Bytes Rx Counts the number of bytes successfully received at the port This also includes local and dropped packets Total Octs Rx Counts the number of bytes octets received on the port in both good frames and error frames Multicast Rx Frames Counts the number of good multicast frames received This includes local and dropped multicast packets Broadcast Rx Frames Counts the number of good broadcast frames received This includes local and dropped broadcast packets Rx Good Frames Counts the number of good frames received This also includes local and dropped packets Tx Good Frames Counts the number of good frames sent from the respective port 64 Octs 65 127 Octs 128 255 Octs 256 511 Oct

The DES 2218 implements the IEEE 803 1d Spanning Tree Protocol STP to provide the following functions Network loop detection and prevention There should only be one path between any two stations on the network If there is more than one path packets will be forwarded in loops forever The spanning tree protocol detects any looping paths and selects the path with the lowest path cost as the active path while blocking other paths and using them as backups Automatic topology reconfiguration If a path for which there is a backup path fails the backup path will be automatically activated and the spanning tree protocol will automatically reconfigure the network topology STP parameters are mainly used to determine the root bridge and root ports on the network If there is a loop in the network data packets will go through the root bridge If the bridge has several ports then the root port will be used to pass data packets to the root bridge STP settings are complex so you probably want to leave these default parameter values as they are If you really need to modify their values please refer to the following discussion 42 Using the Console Interface DES 2218 Ethernet Switch User s Guide Introduction to Spanning Tree Protocol Parameters The Spanning Tree Protocol works on two levels the bridge i e switch and port levels At the bridge level the STP algorithm calculates a bridge identifier for each bridge and
