I have a S2500 that also acts as our Primary Router and another S2500 that will be uplinked to the Router soon, in the same closet, though just as a standard switch.
I just received some fiber to run as our backbone, so I plugged a SFP into a SFP port on the router and also on the second S2500, so they could then communicate. I wanted to test to see if I had to configure anything to get the fiber to work, once I ran it.
I searched in vain for data on how to connect a fiber backbone, but all I could find was stuff on stacking, so I assume Aruba uses stacking when connecting a fiber backbone?
Anyway, the problem is when I unplugged the SFP from the main router all ports on the router went black and the network was dead, though the router was still running.
I plugged the SFP and fiber back in to the original ports and the router ports lit up and all is well.
Problem is, I don't want the second S2500 to be connected to the router via that fiber.
My main question is; How can I undo what I did?
And, not as important, how do I uplink my two closets via fiber? Is it through stacking?
What physical interfaces did you use to connect the fiber?
Hi Thanks for the responseHere is what I have:Also, I just disabled the split detection via the GUI. Hopefully, thatprevents the router from going dark on secondary shutdown.Aruba-DataCenter-1) #show stacking interfacestack1/2--------stack1/2 is administratively Enabled, link is Up, line protocol is UpSpeed: 10 Gbps, MTU: 9224 bytes, Link flaps: 3Last update of counters: 0d 00:00:07 agoLast clearing of counters: 0d 02:04:03 agoLink status last changed: 0d 00:12:35 agoStatistics:Received 498665 frames, 129681275 octets12 pps, 15.292 Kbps184113 broadcasts, 0 runts, 0 giants, 0 throttles0 error octets, 0 CRC frames64999 multicast, 249553 unicastTransmitted 2149639 frames, 784909578 octets29 pps, 34.388 Kbps543320 broadcasts, 0 throttles69000 multicast, 1537319 unicast0 errors octets, 0 deferred0 collisions, 0 late collisionsstack1/3--------stack1/3 is administratively Enabled, link is Down, line protocol is DownSpeed: N/A, MTU: 9224 bytes, Link flaps: 0Last update of counters: 0d 00:00:00 agoLast clearing of counters: 0d 00:00:00 agoLink status last changed: 0d 00:00:00 agoStatistics:Received 0 frames, 0 octets0 pps, 0 bps0 broadcasts, 0 runts, 0 giants, 0 throttles0 error octets, 0 CRC frames0 multicast, 0 unicastTransmitted 0 frames, 0 octets0 pps, 0 bps0 broadcasts, 0 throttles0 multicast, 0 unicast0 errors octets, 0 deferred0 collisions, 0 late collisions
OK...so if port 1/3 is in use and active, that is acting as a stacking port on the Aruba switch. Is port 0 or 1 avaialble? If so, you can just use those as a normal switch interconnect/uplink like any other port on the switch.
OK. Good.But, how do I remove these two switches from being stack members?My Router is reading as Secondary when I plug in the other S2500, but itthen says Primary when I unplug the other switch. Wow, I dug myself in thistime.lolThanks for your help Seth!
OK...on the second unit, issue this command after it's been removed from the stack...
restore factory-default stacking
You can also do this to use ports 1/2 and 1/3 as regular uplinks...this will remove them from being "stack" ports..
delete stacking interface stack 1/2
Thank you. I will issue that command to gladly get rid of them. But, how doI remove the switch from the stack? I deleted it from via the GUI, underconfiguration, stacking, but I can only communicate with it via therouters' IP.Sorry about this.
No worries but I'd call into support and have them help you walk through this just so you gracefully exist this config with no unknown artifacts
Thank you very much for your help. I will call them.
