Re: Connecting switches 2910al and 1950 over SFP+
Thanks for your advice Michal!
I had a slight hope that cable connection could work. Experimenting takes time, and the DAC cables are not cheap either.
I'll stick to connecting the switches with x132 optical transcievers. The cost will not kill my customer, but it's always nice if you could save a buck, or two. The 2910al switches have already got the latest firmware, as each one has got a 10Gb uplink to the main switch since day one.
Best regards,
Peter

Re: IRF configuration with 3 switches
Interesting: HPE OfficeConnect 1950 Switch Series user guide (even the most recent one of August 2016) seems to understimate the IRF configuration necessary steps by showing just a two IRF Stack configuration deployed only through Web GUI (which looks somewhat trivial but doesn't tell the whole story about IRF)...then the fact that the word "Stack" is used on User Guide while the word "IRF" is used on Web GUI and Online Help adds confusion and doesn't help.
To be totally honest the HPE OfficeConnect 1950 Switch Series Getting Started Guide (August 2016) has an entire chapter starting at page 23 totally dedicated to "Setting up an HPE OfficeConnect 1950 stack" (where the word "stack" is literally "IRF", again) with a clear setup flow.
IMHO the best things you can do are:
- Start with Switches in their default state or, at least, with physical interfaces you plan to use as Logical IRF Ports in a default known state.
- Don't connect any physical link you're planning to bind to each Logical IRF Port until (when) the IRF configuration procedure states to do so.
- Start with updated Firmware (must be the same version in all involved units: actually, it's Comware 7.10 Release 3115 Patch 03...R3115P03 published on December 6th 2016...see here).
- keep in mind that IRF Merge methods were changed with R3111P03
- Plan to use IRF Ring or Daisy Chaing topologies: with IRF Ring Topology you will need two Logical IRF Ports (named IRF-1 and IRF-2) on each IRF Stack Member...the Logical IRF-1 Port will be connected to the Logical IRF-2 Port of the next closed neighbour - let's say you start from IRF Member 1 - until you will be able to close the loop by connecting the last member Logical IRF-1 Port (on your third unit) with the first member Logical IRF-2 Port (on your first unit). In case of an IRF Daisy Chain topology the connection schema is similar but you don't close the Loop between the first and last member (so only "in-between" member(s) needs/need to have two Logical IRF Ports defined).
- Forget about "IRF Port Link Aggregation" if you don't have physical ports to be reserved for deploying that feature (I mean binding more than one physical SFP+/10GbE port to each single Logical IRF Port, sort of special Link Aggregation dedicated to IRF links)...you probably will fall into the most simple 1:1 binding case: 1 SFP+/10GbE physical port to 1 Logical IRF Port...if, instead, you have resources/ports - that doubles when you consider a deployment with IRF Ring Topology - you can benefit of enhanced resiliency and load balancing by binding more than one physical port to the same Logical IRF Port.
- Connect physical links (or enable them if you previously disabled them) related to IRF Stack once the IRF configuration procedure finally tells you to do so.
- Keep an eye well open on specific HPE IRF Configuration Guides [*] written for Comware 5/7 based HPE FlexFabric/FlexNetwork units because those guides explains IRF Stack configurations really better (and you can perform any IRF Stack configurations essentially and completely by using the Switch's CLI).
[*] HPE IRF Configuration Guides can be easily found for all HPE FlexFabric/FlexNetwork switch series: as example, have a look at HPE 5500 HI Switch Series IRF Configuration Guide at "Configuring IRF" chapter.

Formatted switch JG9963A
I formatted the switch becasue it was having issues so i figured it would be eaiser to reload. I go into Basic Boot Menu, Update Full Bootrom , use Xmodem to transfer the firmware that i downloaded from here 1950_7.10.R3115P03 upload the 1950_7.10.R3115P03.ipe file and still won't boot. What am I not doing or need to do different? Can someone please list the steps for me and help me out? /G\

How did you supposedly formatted the Switch?
Did you read the Appendix B "Upgrading software" which is available on each Release Noteto restore (the Switch) to its factory default configuration via Extended Boot Menu or what?
The word "formatting"...is not an option IMHO, did you exectued the restore factory-default command via CLI or what?
P.S.
Your other identical post here should be deleted (avoid double posting).

HP-1950 (JG961A) SFP
Hi,
I have found in HP 1950 switch series Quick Spec. document that the J8177C (SFP RJ45) is what I need. Unfortunatly I cannot find how to configure or tell the uplink port that it has an SFP now. I do recall that on other switches other than HP I had to, at least, this paticular port has an SFP now. I do not see any SFP choice on any interfaces in the WEB GUI or the CLI.
Questions:
1- Do I need to configure the port accepting this SFP or not (automatically recongnize)?
2- If I do need to configure the port to accept an SFP, how do I proceed?
Regards
p.s great forum BTW!

Re: Formatted switch JG9963A
No there is actuall a format option Ctrl+F on the Extended boot menu. I have been following this
I did get it working this way. Use FTP, never xmodem haha, it takes forever.

Re: IRF configuration with 3 switches
Would this work? If I added an third into the mix?
- Login onto the switch using the console port
- <H3C>system-view(Enter system view aka config mode)
- [H3C]show version(Ensure that both switches are running the same software version)
- [H3C]reset saved-configuration(Reset the config)
- [H3C]irf member 1 renumber 1(Assign an IRF member number to the first switch)
- [H3C]irf member 1 renumber 2(Assign an IRF member number to the second switch)
- [H3C]quit(Quit to user view)
- <H3C>save(Save the config)
- <H3C>reboot(Reboot the switches)
- <H3C>system-view(Enter system view aka config mode)
- [H3C]irf mac-address persistent always(Enable MAC address persistance)
- [H3C]irf member 1 priority 32(Set the highest priority on the first member/switch aka Master)
- [H3C]irf member 2 priority 30(Set the second highest priority on the second member/switch aka Slave)
- [H3C]int GigabitEthernet 1/0/51
- shut
- [H3C]int GigabitEthernet 1/0/52
- shut
- [H3C]int GigabitEhternet 2/0/51
- shut
- [H3C]int GigabitEthernet 2/0/52
- shut (shutdown all interfaces you want to use for IRF on both switches)
- [H3C]irf port 1/1(Create IRF port 1/1 on the first member)
- [H3C]port group interface GigabitEthernet 1/0/51(add the switch port to the IRF port)
- [H3C]quit
- [H3C]irf port 1/2(Create IRF port 1/2 on the first member)
- [H3C]port group interface GigabitEthernet 1/0/52(add the switch port to the IRF port)
- [H3C]quit
- [H3C]irf port 2/1(Create IRF port 2/1 on the second member)
- [H3C]port group interface GigabitEthernet 2/0/51(add the switch port to the IRF port)
- [H3C]quit
- [H3C]irf port 2/2(Create IRF port 2/2 on the second member)
- [H3C]port group interface GigabitEthernet 2/0/52(add the switch port to the IRF port)
- [H3C]quit
- [H3C]save(Save config)
- [H3C]interface GigabitEthernet 1/0/51
- [H3C]undo shut
- interface GigabitEthernet 1/0/52
- [H3C]undo shut
- [H3C]interface GigabitEthernet 2/0/51
- [H3C]undo shut
- [H3C]interface GigabitEthernet 2/0/52
- [H3C]undo shut(enable all interfaces you want to use for IRF on both switches)
- [H3C]irf-port-configuration active(Activate the IRF config on BOTH switches)
- Now we connect our fiber CROSSWISE, so 1/0/51 to 2/0/52 and 1/0/52 to 2/0/51
- ATTENTION: The second IRF member will reboot! Wait for it to get back up. We will see the switches negotiate for about 30 seconds before the IRF becomes active.
- If all works well;
- [H3C]quit
- <H3C>save
- <H3C>reboot
- <H3C>system-view
- [H3C]display irf(Display the IRF setup)
- [H3C]display irf topology(Display the IRF Topology)
- [H3C]display irf configuration
- [H3C]display devices
- Both irf port should be up. If one is DOWN or DIS(abled), something went wrong.
- Check the IRF priority of the First member. It should be 32.
- Check the IRF priority of the second member. It should be 30.

Re: HP-1950 (JG961A) SFP
That's interesting...even if in the QuickSpecs the J8177C is listed as supported...in the HPE OfficeConnect 1950 Switch Series Getting Started Guide (August 2016) the only one supported SFP (Copper) Transceiver that can be installed on SFP+ Ports and that is listed is, de facto, a genuine JD089B (HPE X120 1G SFP RJ45 T Transceiver).
That's could be the culprit: QuickSpecs reports both JD089B and J8177C, the Getting Started Guide reports only the JD089B.
Anyway, questions:
- Which Software version is the JG961A actually running (Rxxxx or RxxxxPyy)?
- Does this issue (Genuine HPE SFP Transceiver J8177C - HPE X121 1G SFP RJ45 T Transceiver - is not recognized so it doesn't show up on Web GUI or via CLI) still happen after a full power-cycle (On->Off->On)?
- Via CLI (system-view) what is the effect on Switch's Log of executing the undo transceiver phony-alarm-disable command [*] which is available since Software version R3111P02?
- Via CLI (system-view) what is the output of summary and display commands?
[*] The undo transceiver phony-alarm-disable command (it enables the functional check which is disabled by default) means that the Switch will regularly check (any) Transceiver Module eventually installed for its vendor name: if an installed Transceiver Module hasn't a vendor name or if the vendor name it shows is not HPE, the Switch repeatedly outputs Traps and Log messages (which can be useful for debugging).
Technically a fully working, genuine and supported Transceiver should work without any configuration (enablement)...

Re: IRF configuration with 3 switches
I finally got this working, i updated all 3 JG963A's to the latest firmware, disabled the ports on each switch, set up irf ports, enabled ports, set member ID as 1/2/3 on each switch priorty 32/30/28 on each switch, activated IRF, and boom, plug the cables in correctly reboot you are good. Here is a pic of how i plugged the cables in.

Re: IRF configuration with 3 switches
That's good. Yep, glad you find the right path for your IRF scenario:
- On IRF Member id 1: irf-1/1 (XGE 1/0/51) to irf-2/2 (XGE 2/0/52)
- On IRF Member id 2: irf-2/1 (XGE 2/0/51) to irf-3/2 (XGE 3/0/52)
- On IRF Member id 3: irf-3/1 (XGE 3/0/51) to irf-1/2 (XGE 1/0/52) <-- that link closes the loop back to IRF Member id 1

Internet connection problem : connecting switch to router.
I am using HP 1920 8-Port Gigabit Switch in my office. We are using only 5 out of the 8 ports to connect with the 3 systems, printer and server. On port is connected to the router. The problem is, I am facing problems with accessing the internet on the connected computers. The connection drops frequently and I have to unplug and replug the ethernet cable from the router. I checked with the ISP and after inspection, they told that there is nothing wrong. We use 120/10Mbps high-speed cable internet. I would like to know if there is anything I can do you solve this problem, or should I replace the switch?
These are connected to the switch. you can see their specs.

First thing first: you must decide which debugging strategy to follow, top (OS)/down (Physical) or down (Physical)/top (OS) when examining your little network.
Are your PCs (and Server) be able to communicate each others (ping/file transfer and so on...) and so the issue is "only" on the Internet facing side (Default Gateway/Router) or what?
That's to understand where to start diagnosing...
What happens if you test you Internet Connection behind the Linksys Router (LAN side) by connecting just a single PC (a notebook, as example...that's because it will be easy to test) and disconnecting the HPE OfficeConnect 1920-8G Switch (so seizing all the hosts connected to it)? Do you surf the Internet? Which IP Addressing parameters on the host lets it to work that way? and so on...
Supposing that your Linksys EA6900 Router acts - at least in a quite usual and very basic network configuration - as the Default Gateway for all of your hosts (Three PCs, the Server and a Printer)...and it does so by providing NAT (Network Address Translation) between its WAN side (single Yellow Gigabit Ethernet port - "Internet" labelled - connected to the Thompson Modem) and its LAN side (blue Gigabit Ethernet - "Ethernet" labelled - switched ports)...based on the debugging strategy cited above...you should start to inspect layer by layer (e.g. physical layer: physical links, Cat.5E/6 UTP or STP Certified patch cords/cables used, is there a loop somewhere?...and so on...up to the Operating System configuration layer: IP Addressing on each host, DNS settings, DHCP settings, who acts as DHCP Server? and so on...)...it should be not too difficult to understand why you had networking issues and who (or what) is the culprit.
I assume that Software/Firmware and Device Drivers of all involved Hardware units is up-to-date (or, at least, you know that Software/Firmware and Device Drivers are working reasonably well without being so up-to-date or being unmaintained):
- See here for Linksys EA6900 (note the Release Notes here).
- See here for HPE OfficeConnect 1920-8G (JG920A).
- Review the LAN/WAN configuration of the Linksys EA6900 too.
