**PORT DESCRIPTION**

Function Overview

Port description is very important for daily maintenance and trouble shooting. We suggest you to use the format "Link-peer name-peer port" to define port description. For example:

Ruijie(config-if-GigabitEthernet 0/1)#description  Link-to-WLZX_Core_S8610_1-G1/2

 

**I. Configuration Steps**

Configuring port description on G0/1

Ruijie#configure terminal

Ruijie(config)#interface gigabitEthernet 0/1

Ruijie(config-if-GigabitEthernet 0/1)#description Link-to-Core-S8610_1-G2/3

Ruijie(config-if-GigabitEthernet 0/1)#end

Ruijie#write
 

**II. Verification**

Ruijie#show interfaces description

Interface                Status   Administrative Description

------------------------ -------- -------------- -----------

GigabitEthernet 0/1      down     up             Link-to-Core-S8610_1-G2/3

GigabitEthernet 0/2      down     up            

GigabitEthernet 0/3      down     up    


**Speed, Duplex and Flow control**

Overview

By default, speed and duplex negotiate automatically. You can also set speed and duplex manually to ensure that both ends of a link have the same speed and duplex .Usually we keep the default setting for flow control.

 
**I. Configuration Steps**

In the following example, the "speed" config-interface command with the keyword 100 is used to manually set speed on Giga0/24 to 100M

Ruijie>enable 

Ruijie#configure terminal

Ruijie(config)#int gigabitEthernet 0/24

Ruijie(config-if-GigabitEthernet 0/24)#speed 100

Ruijie(config-if-GigabitEthernet 0/24)#end

Ruijie#write   

 

In the following example, the "duplex" command config-interface with the keyword full is used to manually set duplex on Giga0/24 to full duplex

Ruijie>enable 

Ruijie#configure terminal

Ruijie(config)#int gigabitEthernet 0/24

Ruijie(config-if-GigabitEthernet 0/24)#duplex full   

Ruijie(config-if-GigabitEthernet 0/24)#end

Ruijie#write

 

This example shows how to disable flow control feature on Giga0/1

Ruijie#configure terminal

Ruijie(config)#interface gigabitEthernet 0/1

Ruijie(config-if-GigabitEthernet 0/1)#flowcontrol off

Ruijie(config-if-GigabitEthernet 0/1)#end

Ruijie#write

 

Note：By default flow control feature is enabled, but different switches vary, and you can enter "show interface" privilege EXEC command to verify.


**II. Verification**

This example shows how to display interface status including duplex and speed.

**COMBO PORT**


**I. Configuration Steps**

Following example shows how to convert combo mode on Giga0/23 to fiber

Ruijie>enable 

Ruijie#configure terminal

Ruijie(config)#interface gigabitEthernet 0/23

Ruijie(config-if-GigabitEthernet 0/23)#**medium-type fiber**   ------>convert combo mode to fiber

Ruijie(config-if-GigabitEthernet 0/23)#end

Ruijie#write    ------>confirm and save

 

**Following example shows how to convert combo mode on Giga0/23 to copper**

Ruijie>enable 

Ruijie#configure terminal

Ruijie(config)#interface gigabitEthernet 0/23

Ruijie(config-if-GigabitEthernet 0/23)#**medium-type copper**     ------>convert combo mode to copper

Ruijie(config-if-GigabitEthernet 0/23)#end

Ruijie#write   

 

**II. Verification**

1. To display combo mode status , enter "show interface status" privilege EXEC command

Ruijie#**show interfaces status**

Interface                        Status    Vlan    Duplex   Speed     Type 

-------------------------------- --------  ------  -------  --------- ------

GigabitEthernet 0/22             down      1       Unknown  Unknown   copper

GigabitEthernet 0/23             up        1       Full     1000M     fiber

GigabitEthernet 0/24             down      1       Unknown  Unknown   copper

 

2. This example shows how to display the transceiver information of Giga0/23

Ruijie#show interfaces g0/23 transceiver

Transceiver Type    :  1000BASE-LX-SFP  

Connector Type      :  LC                          

Wavelength(nm)      :  1310                     

Transfer Distance   :                                

    SMF fiber

        -- 10km                         

    50/125 um OM2 fiber

        -- 550m

    62.5/125 um OM1 fiber

        -- 550m

Digital Diagnostic Monitoring  : NO        ------>This transceiver doesn't support DDM . DDM provides you the light intensity of receiving and sending direction.

Vendor Serial Number           : LP201093226676  

 

3. This example shows how to display the light intensity of a 10G transceiver which supports DDM

Ruijie#show interfaces tenGigabitEthernet 1/25 transceiver diagnosis

Current diagnostic parameters[AP:Average Power]:

Temp(Celsius)   Voltage(V)      Bias(mA)            RX power(dBm)       TX power(dBm)

26(OK)          3.26(OK)        5.22(OK)            -3.65(OK)[AP]       -2.09(OK)

 

4. This example shows how to display the transceiver alarm

Ruijie#show interfaces tenGigabitEthernet 1/25 transceiver alarm   ------> if the transceivers is plugged in , but the port doesn't come up , system returns the following warning message

RX power low

RX loss of signal

Module not ready

RX not ready

RX CDR loss of lock

 

Ruijie#show interfaces tenGigabitEthernet 1/25 transceiver alarm  ------>if the transceivers is plugged in and the port comes up , system returens no warning message
