About This Guide

This guide includes detailed information on the switch software, including how to

operate and use the management functions of the switch. To deploy this switch

effectively and ensure trouble-free operation, you should first read the relevant

sections in this guide so that you are familiar with all of its software features.

Who Should Read This

Guide?

This guide is for network administrators who are responsible for operating and

maintaining network equipment. The guide assumes a basic working knowledge of

LANs (Local Area Networks), the Internet Protocol (IP), and Simple Network

Management Protocol (SNMP).

This guide focuses on switch software configuration through the CLI.

For information on how to manage the switch through the Web management

interface, see the following guide:

2 Link-Aggregate Port Commands

2.1

Configure relevant commands

link-aggregation load-balance

Configures a traffic balancing algorithm for link-aggregation ports (AGG). Use the no option of

this command to set the traffic balance back to the default.

link-aggregation load-balance {mac|ip-mac}

no link-aggregation load-balance

Null

Global configuration mode

Use the show link-aggregation group command to view the traffic balancing

algorithm.

ECS2020-10P(config)

# link-aggregation load-balance ip

link-aggreation

Creates a link-aggregation group.

link-aggregation {group-number mode { manual | lacp }}

no link-aggregation {group-number}

The physical port does not belong to any link-aggregate group.

Parameter

Description

MAC

The traffic is allocated according to the source MAC address of

incoming packets. In each AGG, packets from different

MAC

addresses are assigned to different ports. Packets from

the

same MAC address use the same port.

IP+MAC

Traffic is allocated based on source IP and source MAC.

Different source IP - source MAC traffic is forwarded through

different ports, and the same source IP - source MAC is

forwarded through the same link.

Command

Description

show link-aggregation group

Usage

Example

Default

Global configuration mode

You can configure manual mode and lacp mode. The no command removes all

interfaces from the aggregation group.

The following example creates a link aggregation group 1

ECS2020-10P(config)#link-aggregation 1 mode manual

Interface link-aggreation

Sets a physical port as a member port of a link-aggregation group. Use the no option of the command to

remove the link-aggregation port member from the group.

link-aggregation group-number [active| passive|manual]

no link-aggregation

{

group-number}

The physical port does not belong to any link-aggregation group.

Interface configuration mode

All AGG member interfaces need to be in the same VLAN.

3 Port mirroring commands

3.1

Configure-relevant commands

monitor session

Create a SPAN session and specify the destination port (monitor port) and source port (monitored port). Use

the no option of the command to delete the session or remove the source port or destination port separately.

monitor session session_number { [ source interface Gigabit Ethernet port-id

[both | rx | tx ]] | [ destination interface GigabitEthernet port-id ]}

no monitor session session_number { [ source interface Gigabit Ethernet port-id

[both | rx | tx ]] | [destination interface GigabitEthernet port-id ]}

Null

Global configuration mode

Switch port and AGG (separate port settings) can be configured as source and

destination

ports. The SPAN session does not affect the normal operation of the switch.

SPAN

sessions can be configured on a disabled port, however, SPAN does not work

immediately until the destination and source port are enabled. A port cannot be both a

source port and a destination port. Use the show monitor command to display the

operating status of the SPAN session.

The following example shows how to create a SPAN session: Session 1. If the session

has already been set up,First clear the configuration of the current session 1, and then

set the port 0 interface to the port

interface 0/1.

ECS2020-10P(config)# no monitor session 1

ECS2020-10P(config)# monitor session 1 source interfaces

4 Port isolation commands

4.1

Configure-relevant commands

isolate-port

Configures port isolation in interface mode. Use the no command to delete the configuration.

By default, port isolation is disabled.

switchport protected

no switchport protected

Turn off port isolation configuration

Interface configuration mode

After the port isolation function is enabled, the ports and link aggregation groups (AGG)

cannot be accessed by each other.

The following is the isolation between port 0/1 and port 0/2.

ECS2020-10P(config)# interface GigabitEthernet 0/1

ECS2020-10P(config-if-GigabitEthernet0/1)# switchport protected

ECS2020-10P(config)# interface GigabitEthernet 0/2

ECS2020-10P(config-if-GigabitEthernet0/2)# switchport protected
