Hi there,
I have 3 Aruba 2930F switches (1 x 28-port and 2 x 48-port).
I have configured all the switches with the same configuration (see attached). the only differences being the model, no. of ports,switch name and the ip addresses for each switch on the 2 vlans.
I have had the 2 48 port switches running on the network for a number of weeks now and I have been getting regular "Warnings and Info" entries in the log for the following;
1) Port "x" PD MPS Absent Indication
2) Port "x" is now offline. followed by Port "x" blocked by STP, followed by Port "x" is now online. - Where "x" is the same number in all of the notifications. This is happening for multiple ports? Am I correct this has something to with the switch not being able to "initially" detect the end-point device?
3) Port "x" PD MPS Absent Indication - the switch no longer detects a device on port "x". Device has been disconnected, powered down or stopped functioning.
The above is happening on all of the switches for different ports.
Some further info...
1) I can ping all the switches on each of their assigned vlan IP addresses. The only exception is the switch zeus (10.1.0.23/10.1.1.5) but I am pretty sure this is because the cable has been removed which links it to the network so not too concerned about that just yet.
2) I can connect to all the switches via web gui and putty (telnet) with the exception of zeus (10.1.0.23/10.1.1.5 and 10.1.0.14/10.1.1.3). as mentioned before ignore the 10.1.0.23 device for now as it isn't connected to the network. I am stumped by not being able to connect to the 10.1.0.14 switch because i know for a fact the server I'm logging into is connected directly to it so it is obviously working, I just can't connect via the webgui or putty (telent).
My real query here though is.... what is the best way to connect these switches together. Refer to attached diagram, My intention is to have one connection going from each switch to 10.1.0.23 (intended "Core switch") so there will be an uplink to each of these switches rather then daisy chaining the switches together... from what I've read daisy chaining is not recommended.
If you have any thoughts on the configuration file, network design and potential improvements, recommendations on making things better that would be appreciated.
Thanks,
