Ethernet Switch User Manual 1 Overview 1.1 Introduction This manual covers the configuration of the ESML6-P3 series using the Command Line Interface (CLI) and the instructions of the command set. 1.2 Switch Management Methods The ESML6-P3 series industrial Ethernet switches are managed by the following methods: Connecting a terminal (or terminal emulation software) with the switch’s Console...
Ethernet Switch User Manual 2.3.2 Password Configuration The ESML6-P3 supports a password checking function in Command Line and Telnet. Go into Configuration Mode (see section 2.2.1). In Configuration mode type: SWITCH(config)# enable password <1-20> 2.3.3 Version number To display the software version number use the following command: SWITCH#show version 2.3.4 Switch running function...
Flow control: The ESML6-P3 supports 802.3-based port flow control. In full duplex mode, if the port receives data beyond its limit, the port will transmit flow control frames to prevent packet loss caused by the rate limit. In half duplex mode, if the port receives data beyond its limit, the port generates back pressure half duplex collision detection frames to reduce the transmitting data from the sending end.
4 Port Speed Limitation 4.1 Overview of the port speed limitation function The ESML6-P3 series supports port transmitting rate limitation, services limitation and broadcast limitation. These all belong to the traffic limitation function which allows: A maximum of 26 ports’ speed limitation at one time.
Port trunking or link aggregation is a method by which physical ports are combined into one logical link to increase bandwidth and improve resilience. The ESML6-P3 supports up to 2 trunk groups and each group can have up to 4 members. The configured services for all ports in the same trunk group should be the same.
8,4,2 or 1, with 8 being the highest priority and 1 the lowest. The ESML6-P3 supports 3 types of scheduling strategies: port based (highest priority), TOS/DIFF and 802.1p (lowest priority). Port based priority only maps 2 queues either highest or lowest, TOS/DIFF and 802.1p support 4 queues.
The weight ratio of high priority is not less than double that of the low priority. 7.2.6 VLAN priority mapping configuration The ESML6-P3 switch supports the 802.1p-based priority scheduling strategy. 802.1p priority determines a message priority by the VLAN tag priority in the 802.1Q messages.
The ESML6-P3 also supports a message auto-query function, so that the switch can be added to the network without a Layer 3 switch or router. It supports the auto-query restraint function which prevents the query message increasing as switches are added.
DT-Ring uses the ring and port status to ensure a redundant ring without creating a loop. It can only be used with other KBC switches. If two networks are to be connected where one is using DT-Ring and the other RSTP, then RSTP Transparent Transmission must be used.
By creating a tree topology it also optimizes the link backup and path selection. The ESML6-P3 series fully supports RSTP and STP and can also be connected with other devices which support STP. Single ports can be enabled or disabled, STP edge-ports can be disabled to avoid causing a block status when the network topology is changed.

SNMP trap to the manager to report the alarm. The ESML6-P3 series supports the alarm search by either a web page search, a CLI/Telnet search or an SNMP management software search.
