Configuring Storm Control on Alcatel OmniStack LS 6224

In this article I will give an example of setting up broadcast and multicast control on the Alcatel OmniStack LS 6224 switch.

Connect to the switch and go into the configuration mode:

enable
configure

Select the ports on which you want to enable Storm Control:

interface range ethernet e1-24

Turn on the control of broadcast traffic and specify a limit of 70 kilobits per second:

port storm-control broadcast enable
port storm-control broadcast rate 70

If you want to limit also multicast traffic, then execute the following command:

port storm-control include-multicast

The standard value is 3500, the possible range for ethernet ports is 70 – 100000, for gigabit ports 3500 – 1000000.

Now it remains to exit the configuration mode and save the configuration:

exit
exit
copy running-config startup-config

To see the data of the packet counters on the port, for example:

show interfaces counters ethernet g1

Firmware Upgrade Alcatel OmniStack LS 6224

I will describe the process of updating the firmware on Alcatel OmniStack LS 6224.

Let’s connect to the device and switch to the mode of elevated privileges:

enable

See the current firmware version:

show version

We look at what firmware versions are downloaded and what is active:

show bootvar

See how much memory is free:

dir

Run the command to copy the firmware file from the TFTP server to the switch:

copy tftp://10.0.0.18/alc6224-1.7.1.12.img image-2

I had an active firmware image-1, so I saved a new one like image-2.
I used the firmware version 1.7.1.12
https://files.ixnfo.com/Firmware/Alcatel-Lucent/alc6224-1.7.1.12.img

Let’s make an active uploaded firmware:

boot system image-2
show bootvar

We reboot the switch:

reload

After reboot, the switch will boot with the new firmware.

If necessary, the firmware file can also be copied from the switch to TFTP:

copy image-1 tftp://10.10.0.18/image-1

How to start the TFTP server I described in these articles:

Reset Alcatel OmniStack LS 6224

I will describe examples of resetting the settings on the Alcatel OmniStack LS 6224 in several ways.

1) Connect to the device and execute the command to delete the configuration and restart:

enable
delete startup-config
reload

Just in case, before deleting the configuration, you can make a backup copy to the tftp server or locally:

copy startup-config tftp://10.10.0.18/startup-config 
copy startup-config startup-config-backup
dir

To return it is possible so:

copy tftp://10.10.0.18/startup-config startup-config
copy startup-config-backup startup-config

2) If the password for the switch is unknown, then connect to it with a console cable, the speed is usually 9600.
Turn on the power switch, waiting for the message:

Autoboot in 2 seconds – press RETURN or Esc. to abort and enter prom.

When the message appears – press the “Enter” or “Esc” key, in the resulting menu select “[3] Password Recovery Procedure”, then “[7] Back” and wait for the device to start.

After that, the switch will start and will not ask for the password, just delete the configuration as I wrote above or change the password to the user:

enable
configure
username admin password PASSWORD level 15
exit
copy running-config startup-config
reload

Configuring Loopback Detection on Alcatel OS-LS 6200

For example, configure Loopback Detection on the Alcatel OmniStack LS 6224 switch.

Let’s look at the current settings for Loopback Detection:

enable
show loopback-detection

Let’s go into the configuration mode, enable and specify some parameters of Loopback Detection:

configure
loopback-detection enable
loopback-detection mode src-mac-addr
loopback-detection interval 30

Turn on the client ports Loopback Detection:

interface range ethernet e1-24,g2-4
loopback-detection enable
exit

g1 I have an uplink, so I did not enable Loopback Detection on it.

Let’s configure automatic activation of the port after 3000 seconds, if it was turned off due to the loop (you can specify the value in seconds 30-86400, standard 300):

errdisable recovery interval 3000
errdisable recovery cause loopack-detection
show errdisable recovery
show errdisable interfaces

Exit the configuration mode and save the configuration:

exit
copy running-config startup-config

Configuring the Alcatel OmniStack LS 6224

By the way, console cable for Huawei and D-Link switches (for example S2326TP, DES-3200) did not approach the Alcatel OmniStack LS 6224, because it does not use the first contact.
When I assembled the working cable according to the scheme, it did not work through the Chinese USB-RS232 adapter, so I had to connect directly to the COM port of the computer.
The standard connection speed is 9600-8-N-1.

The circuit on which I assembled the cable:
1 – white-brown
2 – green
3 – white-green
4 – orange
5 – blue and white-blue
6-4 – jumper
7 – white-orange
8 – brown

Where the digits are RS-232, but I crimped the RJ45 according to the standard)

After connecting to the switch, we will switch to the mode of elevated privileges:

enable

Let’s look at the existing configuration:

show running-config
show startup-config

Now go into the configuration mode:

configure

Configuring video recording to an FTP server from IP cameras and Dahua DVRs

I recently configured the next IP camera Dahua DH-IPC-HFW1320SP-W and decided to use an FTP server for recording.
Since the menu is basically the same on Dahua cameras and DVRs, the FTP entry is configured the same way.

Open the device interface, for example by typing an IP address in the browser.
Open the “Setting” tab, then “Storage” – “Destination”, in the “Path” tab, where “Motion Detection” and “Alarm”, I marked the FTP checkboxes, by the way I could choose only one thing, or “Local ( write to a memory card or HDD) “,” FTP “or” NAS “. After the selection, click “Save” to save the changes.

Now go to the tab “FTP”, tick the “Enable” and specify the connection parameters in “Server Address”, “Username”, “Password” and press “Save” to save the changes.

After that, the device began to write video to the FTP server in mp4 format, however it was impossible to view the history entries via the mobile application and the camera interface.
Files on FTP are sorted into folders by date and time, as a variant of the video can be viewed through any FTP client from a computer or phone, if the camera writes for motion detection, accordingly if there is no motion detection, then there will be no folders and records.

Required! In the “Storage” – “Record Control” menu, you need to select “Stop” in “Disk Full”, if “Overwrite” is selected, then after restarting the camera, in my case, all records from the FTP server were deleted.

If the FTP server is running on Linux, you can, for example, add to Cron a command that will delete the directory older than 30 days so that the disk does not overflow:

find /srv/ftp/ipcam/SNCAM/ -type d -mtime +30 -exec rm -rfv {} \; >> /srv/ftp/ipcam/remove.log

UBNT with firmware 6.0 stop working

I once treated Ubiquiti Networks airMAX® M Series devices with firmware 5+ from the exploit and updated the firmware to the latest, at that time it was the version of XM 6.0 and XW 6.0.
See my article – Removing exploits from Ubiquiti devices

In the 6.0 firmware, the vulnerability was removed through which the exploit was accessed, but there were other bugs.

Literally a couple of weeks later I noticed that there are no connected stations on some bridges in the Access Point (AP) mode, power was lost from the station, the station was booted and connected to the AP, but the AP did not show the connected stations and the traffic did not pass, it’s just and there is a bug.

Solve the problem by restarting the AP, in the future, if the power supply was lost again on the station or it was reboot, there was a high probability of a repetition of this problem.

Fortunately, this problem was later eliminated in new firmware, I did not exactly look at which version, but on devices with firmware 6.1+ it was no longer observed.

Foscam FI9821W V2.1 Firmware Upgrade

I updated the firmware on several Foscam FI9821W V2.1 cameras on which there was such firmware version:
System Firmware Version: 1.5.2.11
Application Firmware Version: 2.21.1.127
Plug-In Version: 3.0.0.2

The camera receives an IP address via DHCP both via cable and Wi-Fi, so you can find out its IP in the router menu or on the same network as the camera by running the IP Camera Search Tool utility:
https://files.ixnfo.com/Soft/Network/Foscam/03_IP_Camera_Search_Tool.zip

The standard login admin without a password, the first time you connect it, you must change it and specify a new password.

Before the process of firmware download the archive with the firmware from here:
https://files.ixnfo.com/Firmware/Foscam/FI9821W_V2.1.zip

You can also see if there are newer firmware versions on the official site:
https://www.foscam.com/downloads/firmware_details.html?id=91

And so, open the web-interface of the camera by typing its IP-address in the browser.
Let’s see the firmware version on the first tab “Status“.

Next, open “System” – “System Upgrade“, click “Browse“, select the firmware file and click “System Upgrade” to start the upgrade process.
If the firmware in the camera is very old, as in my case, then it is necessary to update first the intermediate firmware (it is also in the archive in the directory “Older firmware V2.x.2.18” link above), and it is updated by two files, first Step1, later Step2.
Then you can sew the newest when I sewed it was FosIPC_B_app_ver2.x.2.23.

That’s all, after the camera firmware settings are not reset, I updated the firmware remotely.
