Chapter 4 Port Configuration
4.1 Introduction to Port
ES4700 series comes with line cards and master management cards. Line cards
provide various network ports. The master management cards provide 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 index is marked on the panels
of all the line cards for the ES4700 series.To distinguish between ports in different line
cards, the port nomination (in the sense of software) provided by the ES4700 series
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, the “
interface ethernet
<interface-list>
“ command can be used 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
management cards, 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
