Dear Experts,

I recently ran into some issues with my new Switching equipment. Since cost is always a big factor in home lab toying I changed from HP ProCurve to the Ubiquiti EdgeSwitch. More specific I change my 2920-24G with a 2SFP+ and a 2 10GBe extension to a Ubiquiti ES-48 and a Ubiquiti ES-16-XG.

Since I have now more than enough SFP+ Ports for my home lab toying around I wanted to create LACP between the Node (ESX Host) and the Ubiquiti ES-16-XG to connect the node with maximum performance to the Synology DS3615xs which I also upgraded with a dual Port SFP+ Card.

Here a little schema

Now the Synology DS3615xs was very easy to setup and as you can see in the attached picture (SynologyLACP.png) seams to be working as a dynamic lacp member on the ES-16-XG.

With the vSphere 6.5 Distributed Switch it seams like a whole other story... I can't seam to find the ressources or manuals where they describe how to do it with the DS or how to get it working.

Can someone point me in the right direction?

Thanks in advance

Cheers,
Yves

Dear Experts,

My colleague somehow remove / deleted the HP switch files.

When I turn it on, it displays this?

How can I resolve this?

I am remodeling four homes.  I have  installed eight port structured wiring systems in all four.  Each wall jack (room) includes one ethernet jack, one cable jack, and one phone jack.  Everything is homerun to the utility room in the basement. Within the wiring cabinet located there, are punch down blocks and patch panels for all wires and cables. I would like to install  in each cabinet, an eight port router or switch to include an integrated DHCP server, and POE  jacks. One of these Jack's will be wired to a ceiling mounted Wi-Fi access point on the third floor in the center of the home. This device should be dual band AC 1200  or greater. Ultimately, the router or switch will be plugged into a cable modem providing Internet and telephone service. I am having trouble finding the router or switch, which needs to be small enough  to fit inside the wiring panel.  I also need an inexpensive access point device.  The cable modem will be mounted by the cable service provider outside the panel.  This arrangement will allow plug-and-play of any wired or wireless device in the home without the need for a PC  based DHCP server arrangement. Has anyone done this? Any recommendations? I need to keep this reasonably inexpensive.

Hello all,



I'm having problems pinging from my data subnet (192.168.0.0/24) to my voice subnet (10.10.10.0/24). data subnet is connected to 0/1 and voice subnet to 0/2 on my ASA5510. I've tried adding static routes on each of the switches and enabled ip routing as well. Voice Switch has VLAN1 with ip 10.10.10.2 with 10.10.10.1 being the IP on 0/2 on ASA.  Likewise Data Switch has VLAN1 with ip 192.168.0.2 and interface 0/1 on ASA has 192.168.0.1.



Can someone please point me in the right direction?



Thank you!

Hi All,

I'm currently looking at this proposal & thinking of implementing OSPF & MLPS I'd like some support with the config & any ideas of best practices?

Thank you all.

I have a security camera project that requires a run of about 1000FT for a few cameras.

I know Cat5/6 are not options due to the 300ft limitation.  I guess I could use POE switches at 300/600/900 ft as repeaters but that doesn't sound like a viable solution.

any ideas?

Hi,

My apologies if I'm unable to put the question right, I am a beginner and would not understand why Im not able to log into the redundant device. These are Cisco WS-6509-E running the WS-SUP720-3B

I am trying to do an IOS upgrade on 2 devices

Device A

Device B (Redundant to Device A)

These are Access level switches and Im using SecureCRT to log into the devices. I am successfully able to log in the Device A and back up the configs. However when trying to log in to Device B - it gives me the below error

ssh: connect to host xx.xxx.z.15 port 22: Connection refused

IP of device A is xx.xxx.z.14.

What can be done in this case? Thanks in Advance !

We have a Cisco WS-C2960X-24PS configured with 4 SFP modules running 2 separate fibre ring networks 1 with 10 comnet switches, the second with 5 comnet switches. We use RSTP to control the rings to ensure port blocking.

All worked fine until the second ring was introduced onto the switch, now we have the first ring failing to block a port upon a topology change.

I am wondering as my Cisco knowledge is 10 years out of date, are the company that setup the Cisco, correct in saying that the Cisco will block both rings using RSTP.

Many Thanks

Vlans Created on Cisco Sg300 Switch not working

I have created Multiple vlans on a Cisco SG 300 switch and wanted to terminate it on olt Interfaces

my topology is - Main Mikrotik Router --> Cisco Switch --> GEPON OLT Syrotech

1) main router Mikrotik... Eth-5(router) connected to Gi-1 (switch)

2) on switch i have created 8 vlans - which are 21 to 28

3) the switch port connected to router i have made it a Trunk  

4) Switch Port is connected to OLT's Uplink port and on both ports are trunk and Tagged with 21 to 28 vlans.

5) OLT's 8 fiber ports are access ports and a single Vlan is untagged on them.

means
OLT port 1 - Acess port vlan 21
OLT port 2 - Acess port vlan 22
OLT port 3 - Acess port vlan 23
OLT port 4 - Acess port vlan 24
OLT port 5 - Acess port vlan 25
OLT port 6 - Acess port vlan 26
OLT port 7 - Acess port vlan 27
OLT port 8 - Acess port vlan 28    

but i cannot acsess or ping my router from olt access ports.
am i doing anything wrong ??

give me configuration of this topology

Need a python script that will take backup of cisco ios switch to tftp server

I have solarwinds to monitor the traffic .
I see (in solarwinds) cisco fast ethernet with 100% utilization although  the top conversation appears (in solarwinds)  in small payload of traffic in KB level .
How does that occur?

How to automate a cisco ios upgrade process using a script like python or any other script or any other tool
