2. Some commands are global, that means they can be performed in all modes:
show: Displays all information of switch, for example: statistic information, port
information, VLAN information.
history: Displays the commands history.
1.3 Security Levels
This switch’s security is divided into two levels: User level and Admin level.
User level only allows users to do some simple operations in User EXEC Mode; Admin level
allows you to monitor, configure and manage the switch in Privileged EXEC Mode, Global
Configuration Mode, Interface Configuration Mode and VLAN Configuration Mode.
Users get the privilege to the User level once connecting console port with the switch or logging in
by Telnet/SSH. However, Guest users are restricted to access the CLI.
Users can enter Privileged EXEC mode from User EXEC mode by using the enable command. In
Global Configuration Mode, you can configure password for Admin level by enable password
command. Once password is configured, you are required to enter it to access Privileged EXEC
mode.

1.4 Conventions
1.4.1 Format Conventions
The following conventions are used in this Guide:
Items in square brackets [ ] are optional
Items in braces { } are required
Alternative items are grouped in braces and separated by vertical bars. For example: speed
{10 | 100 | 1000 }
Bold indicates an unalterable keyword. For example: show logging
Normal Font indicates a constant (several options are enumerated and only one can be
selected). For example: switchport type { access | trunk | general }
Italic Font indicates a variable (an actual value must be assigned). For example: bridge
aging-time aging-time
1.4.2 Special Characters
You should pay attentions to the description below if the variable is a character string:
These six characters ” < > , \ & cannot be input.
If a blank is contained in a character string, single or double quotation marks should be used,
for example ’hello world’, ”hello world”, and the words in the quotation marks will be identified
as a string. Otherwise, the words will be identified as several strings.
1.4.3 Parameter Format
Some parameters must be entered in special formats which are shown as follows:
MAC Address must be entered in the format of xx:xx:xx:xx:xx:xx.
One or several values can be typed for a port-list or a vlan-list using comma to separate. Use
a hyphen to designate a range of values, for instance 1,3-5,7 indicates choosing 1,3,4,5,7.
The port number should format as 1/0/3, meaning unit/slot/port. The unit number represents
the unit ID of the switch in the stack. The slot number is either 0 or 1, with 0 representing ports
on the front panel and 1 representing the two ports on the Interface Card inserted into the
back panel. The port number is a variable (an actual value must be assigned).

no gvrp timer [leaveall | join | leave]
Parameter
leaveall | join | leave —— They are the three timers: leave All, join and leave.
Once the LeaveAll Timer is set, the port with GVRP enabled can send a
LeaveAll message after the timer times out, so that other GARP ports can
re-register all the attribute information. After that, the LeaveAll timer will start to
begin a new cycle. To guarantee the transmission of the Join messages, a
GARP port sends each Join message two times. The Join Timer is used to
define the interval between the two sending operations of each Join message.
Once the Leave Timer is set, the GARP port receiving a Leave message will
start its Leave timer, and deregister the attribute information if it does not receive
a Join message again before the timer times out.
value ——The value of the timer. The LeaveAll Timer ranges from 1000 to
30000 centiseconds and the default value is 1000 centiseconds. The Join Timer
ranges from 20 to 1000 centiseconds and the default value is 20 centiseconds.

high-bandwidth data path, which can highly extend the bandwidth. The bandwidth of the LAG is
the sum of bandwidth of its member port.
LACP (Link Aggregation Control Protocol) is defined in IEEE802.3ad and enables the dynamic link
aggregation and disaggregation by exchanging LACP packets with its partner. The switch can
dynamically group similarly configured ports into a single logical link, which will highly extend the
bandwidth and flexibly balance the load.
