Chapter 7 Port Configuration

7.1 Introduction to Port

ES4710BD comes with line cards and master control boards. Line cards provide various
network ports. The master control boards provide no network ports, only Console interface and
network management port. The Console interface and network management port are used for
out-of-band management of the switch. This chapter focuses on network ports and the network
management port.
Network ports are provided by the line cards. The port numbers are marked on the panels of all
the line cards for the ES4710BD.To distinguish between ports in different line cards, the port
number (in the sense of software) provided by the ES4710BD system is "ethernet X/Y", where X
stands for the slot number for the card and Y stands for the number marked in the card panel. For
instance, a EM4700BD-12GX-SFP line card is inserted to slot 1, then port 3 of this card corresponds
to "ethernet 1/3". If the user needs to configure some network ports, he/she can use the "interface
ethernet <interface-list>" command to enter the appropriate Ethernet port configuration mode,
where <interface-list> stands for one or more ports. If <interface-list> contains multiple ports,
special characters such as ";" or "-" can be used to separate ports, ";" is used for discrete port
numbers and "-" is used for consecutive port numbers. Suppose an operation should be performed
on ports 2, 3, 4, 5 of the card in slot 1 and ports 8, 9, 10 on the card in slot 3, the command would
look like: interface ethernet 1/2-5;3/8-10. Port speed, duplex mode and traffic control can be
configured under Ethernet Port Mode causing the performance of the corresponding network ports
to change accordingly.
The Network management port is located above the Console interface on the master control
boards, marked as "Ethernet", the software configuration name for this port is "Ethernet0". The
user can use the command "interface Ethernet 0" to access the network port configuration mode.
The user can use programs such as Telnet, Web management and FTP to manage the switch through
a Ethernet cable connected to the network management port. The network management port can
neither perform data forwarding like the network interfaces, nor use Layer 2 protocols (like RSTP)
and Layer 3 routing protocols, nor identify the cable type automatically (such as crossover cables
that are required to directly connect to a PC). The network management port supports connection
speeds of 10/100 Mbps, it can have an IP address configured in addition to properties such as speed
and duplex mode. If the switch has 2 master control cards and both are operating normally, only the
Ethernet port in the Active Master can be used as the network management port. When
Active-Standby occurs, the network management port will change accordingly.
