Re: Converting SFPs from stacking to uplink in 2500

3+4 are not stacking ports out of the box. Did you change them? 

The command is 
Delete stacking interface

Re: Converting SFPs from stacking to uplink in 2500

No I didn't change them These ports can be used as uplink ports or a combination of two uplink ports and two stacking ports. By default, Ports 0 and 1 are configured as uplink ports and Ports 2 and 3 are configured as ArubaStack ports. The ArubaStack ports are indicated by a box around the port number. These port assignments can be changed to meet your configuration needs from the CLI.

Re: Converting SFPs from stacking to uplink in 2500

You are correct, the 2500 has 3 and 4 as stackign and 1 and 2 as normal uplink ports.  Try the commands above andyou should be able to convert 3 and/or 4 to normal uplink ports.

Re: Converting SFPs from stacking to uplink in 2500

I think Cappalli hasn't had his coffee yet this morning so he didn't correlate SFP3 and SFP4 to mean the latter two ports of the uplink (0/1/2 and 0/1/3).

 

Clembo has provided the proper instructions on converting the ports to normal uplink ports.

 

Best regards,

Re: Converting SFPs from stacking to uplink in 2500

Thanks All,

 

it worked

 

I have another question

 

I have 2 Corinex powerline adapters that I use to connect 2 points as there no is way to install any cable

When I connect them to any 2 switches or laptops they work fine, but when I use them between 2 Aruba switches S1500 they don't work.

 

So I think that there is something which block their traffic

Anybody can help??

 

Thanks in advance

When you connect these on S1500, even port LEDs won't glow ?

 

or, just that traffic is not passing ? In that case can you check one of these port has moved to STP blocking state (show spanning-tree)

 

 

Thanks,

Yes, the led is on and the traffic is blocked And when I disabled the spanning the port turned down How can I permit traffic in this case?
