Using third-party SFP modules in Cisco switches

Suppose we connected a third-party module to the first SFP port, we’ll look at the information about it:

show idprom int GigabitEthernet 1/1

In my case, on the Cisco Catalyst 6509-E, very many ports with third-party SFP modules after some time they turned off and in the logs information was written that the module was not supported.

Now go into the configuration mode:

enable
config t

And we will make sure that the interfaces are not disabled when third-party SFP modules are enabled by entering the following commands:

service unsupported-transceiver
no errdisable detect cause sfp-config-mismatch
no errdisable detect cause gbic-invalid

After that, everything worked well.

Configuring TP-Link EP110

On the test I will connect TP-Link EP110 ONT to BDCOM P3310B-2AC EPON OLT.

To configure the TP-Link EP110, you must connect it to the computer with a cable and type in the address bar of the browser http://192.168.1.1, then disable the DHCP server from the menu by unchecking DHCP.

It is also necessary to select the ONT mode as shown in the figure below:
tp-link-ep110

After that, TP-Link EP110 will work and register similarly to other ONTs, such as BDCOM P1501C1, FOXGATE 1001w, etc.

Addition of ONT Huawei EchoLife HG8110 on Huawei SmartAX MA5683T

On the test, I wrote the profiles and added ONT Huawei EchoLife HG8110 to Huawei SmartAX MA5683T.

The first step is to connect to the Huawei SmartAX MA5683T and go into configuration mode:

enable
config

Create ont-srvprofile:

ont-srvprofile gpon profile-id 14 profile-name "Huawei HG8110"
ont-port pots 1 eth 1
port vlan eth 1 translation 228 user-vlan 228
commit

Create ont-lineprofile:

ont-lineprofile gpon profile-id 14 profile-name "Huawei HG8110"
tcont 4 dba-profile-id 11
gem add 1 eth tcont 4
gem mapping 1 0 vlan 228
commit

We learn the serial number of ONT and the number of the card to which it is connected by typing the command to search for new ONTs:

display ont autofind all

Let’s go into the setup mode of the desired Gpon card (in the port of which the ONT is connected):

interface gpon 0/5

Now add ONT with the serial number:

ont add 3 17 sn-auth "414C434CF23D5EAF" omci ont-lineprofile-id 14 ont-srvprofile-id 14 desc OPISANIE
ont port native-vlan 3 17 eth 1 vlan 228 priority 0

Where number 3 indicates the Gpon port number to which the ONT is connected.

The number 17 means ID ONT and is listed next in order after added in the ONT configuration, the list of occupied IDs can be seen after exiting the Gpon card setup mode and typing the command displaying the entire configuration (for each gpon port, their IDs ONT):

display current-configuration
display current-configuration | include service-port

Let’s exit the Gpon interface configuration mode:

quit

Add a service port that will give the Internet to ONT (the number 425 denotes the port service number and is taken from the free in the configuration):

service-port 425 vlan 228 gpon 0/5/3 ont 17 gemport 1 multi-service user-vlan 228

Save the configuration:

save

The standard IP address of Huawei EchoLife HG8110 is 192.168.100.1, the login is telecomadmin, the password is admintelecom.
In ONT, you do not need to configure anything.

Setting up and using Traffic Flow in Mikrotik

Enable Traffic Flow on the Mikrotik router:

ip traffic-flow set enabled=yes cache-entries=4k set active-flow-timeout=30m inactive-flow-timeout=15s interfaces=all

View settings:

ip traffic-flow print

Specify the IP address and port of the computer that will receive the Traffic-Flow packets:

ip traffic-flow target add address=192.168.88.240:1234 disabled=no version=9 v9-template-refresh=20 v9-template-timeout=30m

or

ip traffic-flow target add address=192.168.88.240:1234 disabled=no version=5

View settings:

ip traffic-flow target print

To configure through the GUI, the settings can be found in the menu IP -> Traffic Flow.

For monitoring under Windows, you can install the program ManageEngine NetFlow Analyzer, which will work as a server, receive packets from the specified port and generate graphs and statistics via a web server that can be opened by the browser.

For monitoring under Linux, you can install and configure for example flow-tools.

How to find out the password for Huawei EchoLife HG8245

Configured today GPON ONT Huawei EchoLife HG8245C to OLT and it was necessary to go to its web interface to change the password on Wi-Fi, and the standard root login and password admin did not fit. I had to perform several manipulations.
Of course, to begin with, connect to any of the LAN ports, wait until the DHCP ONT is turned on, it will give out IP, such as 192.168.1.2 or set it manually.
Connect via telnet to ONT IP 192.168.1.1, enter login root and password admin.
Then type the following commands one at a time:

shell
cd /mnt/jffs2/
grep admin  myconfig.xml

As a result, the last command gives information about what is happening in the web interface:

useradmin
vufum

and

telecomadmin
nE7jA%5m

Passwords can also be written on the device label. In the settings you can change the password, in this case the user will be useradmin and the specified password.
For HG8245, the standard administrative login and password telecomadmin \ admintelecom, for users – admin/admin. For Chinese HG8245C standard – telecomadmin \ nE7jA%5m.
There may be further passwords for telecomadmin:

NWTF5x%RaK8mVbD
NWTF5x%

Configuring an FTP server on MikroTik Router OS

Usually an FTP server on MikroTik Router OS is enabled and uses ports 20 and 21 for communication.
Connection type without encryption, login and password are same as for access to mikrotik.

You can connect by typing the ip address of the router in the browser’s address bar:
ftp://192.168.88.1

Via the graphical interface, the FTP service is turned off and turned on in the “IP” – “Service”

Through the command line:

ip service disable service_number
ip service enable service_number

View a list of services:

ip service print

To view the information about the files, you can run the following command:

file print detail
disk print detail

Adding ONT PICOTEL PU-G510 on Huawei SmartAX MA5683T

Suppose that we set up Huawei SmartAX MA5683T and added lineprofile/srvprofile using this instruction: Configuring Huawei SmartAX MA5683T through the console

Next, add ONT similarly as I wrote in the article Alcatel-Lucent I-010G

On the test after adding ONT PICOTEL PU-G510 to OLT Huawei SmartAX MA5683T, when connecting the computer to ONT – the Internet worked, when connecting the router – no.
Therefore, I still had to open the ONT web interface, pointing in the address line http://192.168.1.1 (login and password – admin), before registering the computer with a static IP 192.168.1.2.
In the web interface, select the menu “Admin” – “GPON Settings”, where “OMCI OLT Mode:”, if using Huawei OLT – select “Huawei OLT Mode” and click “Apply Changes”.

See how I did it on video:
