Hi,
"i" for [Initialize Config] should exist in your Boot-Menu.

Additionally please try "RW" and "securepasswd"

Hi Matze

I have tried those options and neither works... I am at the point of using Ymodem to try and reflash the software, I am just unsure as to what the breakdown of the steps is. Or which order or even wether this will fix my problems... do I need a specific agent .img file for this bootloader.... etc

Hi

Itís nice to hear that SPBM fabrics are not going anywhere ...
With all that talk about EVPN and overlays

I bought an ERS3526T-PWR+ series network switch that I am unable to access or initialise due to a lost password, I asked the owner! I suspect it has been secured somehow due to the limited menu options. I have connected via Serial using ExtraPutty which has a Y-Modem file transfer feature.
"Ctrl-Y" with the user "RW" and the password "secure" does not allow access.
So then I rebooted and pressed "Ctrl-C" and got Bootloader Vn 1.0.0.3

The menu says:

1 Download            Diag
2 Download            Agent
3 Download            Boot loader
A Continue Boot    System
B Reset

"i" returns to the bootloader menu and doesn't do anything. A continues, B reboots rather than resetting anything.

Options 1, 2 and 3 only allow a Y-modem file transfer (i.e. no TFTP option)

Using option 1 I have used Y-modem to uploaded the ERS3500_b5_3_0_1.bin bootloader file which I obtained from the Avaya dealer support web site. The file copied successfully. There was no Reprogram Y/n prompt although I am not sure there should be one.

When the system reboots it still has bootloader 1.0.0.3

I don't know if there is another instruction I need?

Am I working along the correct lines? Can anyone give me some advice on how to recover this please? Get the proper menu back? Reset the passwords. Do I have the wrong default name and password?

The unit does get an IP address from DHCP if I attach it to a network.

My experience with hybrid stack, going back to ES450 stacked with BPS2000, is that it's a solution best left alone. Stack 5500s with 5500s and 5600s with 5600s. 5510 has limits on a number of features compared to the 5520/5530, I have some traumatic memories of mixing even these two siblings in a stack!

I would suggest a loopback interface running OSPF in passive mode... you could assign a /32 address to the loopback, let OSPF figure out the routing, then you have a single IP address to manage the switch/router regardless of what /30 network is up or running to get to said device.

Cheers!

HP Networking / challenging wide network OSPF + HP comware + OOB management :)
« Last post by romnet on September 10, 2018, 02:18:45 PM »
Hey guys, I'm looking for your opinion on the following :

Big routed network for a country-wide tetra network. We have routers (actually L3 switches from HP) that are in several locations, all connected by various long-haul (licensed) wireless links.

My concern is : the client previously broadcasted a management vlan with all its OOB management interfaces, let's say vlan number 100. There was also a OSPF instance running on all switches connected to between 1 and 4 other switches (mesh network). On top of that STP running as well :)

I'm trying to figure out good practices I could propose them :

1st approach : change all links between switches to "route" mode and not bridge (cisco equivalent : no switchport), and then make all vlans actually routed. In this scenario, I guess I need to have on small, let's say /30 network for local management that will be routed, each location having it's all /30 management network.

2nd approach : keep the same mix as they did, with OSPF + vlans running together, good thing is the management vlan is the same everywhere and is not affected by OSPF malfunctions :D

That's a tricky question I think, 1st approach looks better to me, but I have never deployed such wide network with routing + OOB management  :) any clues ?

Hi, as well the 56xx needs to be the Base-Unit (BU).

I would not recommend that design, as well you will limit the "Stacking-Power" to the level of the 55xx.

Cheers
