Extreme / Avaya / Nortel Ethernet Switching / New podcast about extreme fabric

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.

It's been a little while since I used a hybrid stack, but I recall they had to be running the same firmware version across all the switches.  The last version that supported the 5510/5520/5530's and 5600's was v6.3.6.  So I don't think this is going to work for you.  If you need 10Gig ports, you may have to look for a 5530 that has the two XFP ports on it.

Extreme / Avaya / Nortel Ethernet Switching / Stacking with Avaya 5650-TD & 5510/20
« Last post by AVAGO on September 05, 2018, 04:39:43 AM »
Hi
   Looking to add a 5650-TD to our current stack of 5510/20 so that we can use the 10GB xfp between two buildings, But I'm not sure if stacking between these is possible with FW-6.6.x even when set to operate as a hybrid

The stack as is has the 5520-PoE as the base and has 3 additional 5510 in the stack, so looking at removing one of the 5510 then make the 5650 the base, need to leave the 5520 in as its providing power to some AP's

any advice greatfully received

Avaya (Blue) / Nortel Call Servers / 8XX Number in Target Lines (BCM)
« Last post by scottb8888 on September 03, 2018, 09:47:51 AM »
Bring to use a "new" 833 number as a target line with the receive digits as 833********.  The BCM does not recognize the new *xx code recently released (More recent that BCM :)
