Re: HP 1920s OID CPU Utilization and memory

Can you show an example of the command - I try in my case :
check_snmp -H 172.26.167.153 -C swirc2018! -o .1.3.6.1.4.1.11.5.7.5.7.1.1.1.1.4.9.0
but get a string output:
SNMP OK - " 5 Secs ( 24.1258%) 60 Secs ( 29.4616%) 300 Secs ( 18.4320%)" |

How can I parse it to an integer - I don't care about all the last 60s....   just want last value of now or last value of last 5 seconds ...etc? 

 

What is the command? 

I tried /usr/local/nagios/libexec/check_snmp -H 172.26.167.147 -C swirc2018! -o .1.3.6.1.4.1.11.5.7.5.7.1.1.1.1.4.9.0 -R \s60\sSecs\s\(\s*(\d+)   but it didn't parse.

 

Please help? (-;

Hello

I have a 1920-8G-PoE+ switch, i need to factory reset so i can use it on my home network. I can login into the switch but i cannot enter any commands without getting '% Unrecognized command found at '^' position.' even when bypassing the running config. I cannot find the IP for the web interface either so CLI is the only way i can factory reset it. I'm new to CLI can anyone give me and idea on how to do this ? 

Thank You

1920S Series igmp-snooping not working as expected

Hello Forum,

the igmp-snooping feature in 1920S series switches seems a bit limited and makes it mostly unusable for some sort of modern office networks. I don't think someone from the forum can help me with this case, it's more as information for admins who need igmp-snoop feature and maybe interested in JL380A 8-port PoE-in driven Switch. These Series also missing a dhcp-snoop feature, anyway.

I run into trouble with JL380A and JL384A with mdns and IGMPv3 querier and IGMPv3 devices.

First, from configuration manual written it only understand IGMPv1 and IGMPv2 ... well mostly new WLAN APs from Ubiquity, Ruckus and maybe i think Aruba too implementing IGMPv3. In my environments i have VLAN based igmp-snooping configured, regardless what is configured these switches not forwarding IGMPv3 queries. If your'e downgrading your network to IGMPv2 everything is working as expected without your IGMPv3 WLAN equipment... huiuiui

But next show stopper is not configurable, but i believe it's default set, droping of unknown multicast. Means everything what is not known from querier, cause maybe it's not speaking IGMP but using also multicast addresses like mdns 224.0.0.251, get dropped. This is an absolute must have to disable globally or best case per VLAN. With the older comware based 1950 Series this runs like charme mdns service to all ports and igmp multicast traffic got only to this ports where receivers want it.

regards,

Hi,

Is TFTP server reachable from switch?

Check space available in flash., if available space is less then file size then also you will get this error.

Thanks!

Имеем 3 коммутатора:

 

  1. HPE 1950 48G 2SFP+ 2XGTPoe+ – 2 штуки (SN: CN97GQW0BTи CN8AGQW0GP)
  2. HPE 1420 24G 2SFP+ Switch– 1 штука (SN: CN91GVJ02N)

 

При подключении коммутатора HPE 1950 к HPE 1420  через оптический кабель наблюдаем отсутствие линка на подключаемых портах. В веб интерфейсе HPE 1950 видим что трансивер успешно подключен, но порт находится в down.

 

Для проверки работоспособности модулей (трансиверов) и оптического кабеля соединили  HPE 1950 с другим HPE 1950 – линк пошел, в вебинтерфейсе порты в up, трафик через оптику бегает.

 

 Подскажите, каким образом нам «подружить» HPE 1950 и HPE 1420 с использованием оптики.

Pay attention:

SFP slots on HPE OfficeConnect 1950 are really SFP+ ones (are you using SFP+ or just SFP transceiver)? the HPE supports both SFP and SFP+ Transceivers but the 1420 only SFP.

SFP+ = 10 Gbps

SFP = 1 Gbps

Since the HP 1420 supports only SFP Transceivers...we really hope you're testing SFP Transceiver on the HPE 1950 side and not SFP+ ones...isn't it?

Can you post the SKUs (Model) of used Transceivers?

I have the same problem as you.

I am also using the HPE 1820-24G switch.

I found that CPU/MEMORY can't be found in MIB, so I can only collect it with your script.

Can you e-mail me your complete script?

I couldn't run the code above because I don't know python.

I want to get your .py file.

I would be very grateful if you could provide it.

Thank you.

Hi Athanz

Can you please share some more details as from where relay dhcp request is being sent.

DHCP Relay Agent Information Option 82 is an extension to the Dynamic Host
Configuration Protocol (DHCP), and is defined in RFC 3046 and RFC 3993.

This is my python script and bash script sample called python script. The $1 $2 $3 $4 is argument. 

This is sample when you need get memory used percent:

"/usr/bin/python /usr/lib/zabbix/externalscripts/HPSwitch.py ip_switch getMem username_webconsole_Switch password_webconsole_Switch"

"/usr/bin/python /usr/lib/zabbix/externalscripts/HPSwitch.py 192.168.1.245 getMem admin 123456"

for getCPU

"/usr/bin/python /usr/lib/zabbix/externalscripts/HPSwitch.py 192.168.1.245 getCPU admin 123456"

You need to setup python on server and install "requests, json, sys" library. I writen this script long time ago. I can't remember exactly. May be the library ready existing in python when you install it.

The last, Your monitor system must be support extenal or internal script like zabbix.  And you will create extenal or internal script item.

Please talk me detail your problem. I will support you. (your monitor system, url your hp switch web console)

The url web console must to same url bellow:

url = "http://" + sys.argv[1]     (http://192.168.1.245)
urlLogin = "/htdocs/login/login.lua"   (http://192.168.1.245/htdocs/login/login.lua   -     login url web console)
urlData = "/htdocs/pages/base/support.lsp"    (http://192.168.1.245/htdocs/pages/base/support.lsp - have cpu and memory info in here)
urlLogout = "/htdocs/pages/main/logout.lsp"     (http://192.168.1.245/htdocs/pages/main/logout.lsp  -  logout url web console)

Sorry for my bad English!
