New Switches - 4800's
« on: September 06, 2011, 07:15:14 PM »
Looks like Avaya is bringing out some new switches.  I can't directly post the data sheets (yet), but they stack with 4500's.  Come in 24 and 48 port versions PoE+ and non-PoE versions.  Supply up to 32.4 watts of PoE per port.  Dual replaceable power supplies in either 300w or 1000w flavors.  Support SFP+ for the uplinks, so you can go 1Gig or 10Gig on the switch.

Oh, and they say they use an RJ-45 serial plug now...  Guess that Cisco console cable I have hidden in the back of my desk will get some use again.

Sounds very interesting, any hints when the ERS4800 switch series will be available ?

Should ship later this month with pre-release software, or be GA next month with the new code that the 4500's will use as well.

Do you have more technical details about 4800's.

The specs I have for the 4800's is virtually identical to the existing 4500 series specs with the addition of 10Gig SFP+ ports, PoE+ and dual swappable power supplies in 300 or 1000 watt versions.  The GA software for the 4800's is going to be new v5.6 software.  The software update looks to be more of interest to me honestly since I don't need to try and charge a laptop via the PoE+ on the switch...

Release v5.6 new features:
1) ECMP
2) Layer 3 brouter ports
3) IGMP querier and snooping/proxy
4) Voice VLAN integration
5) VLAN scaling
6) Many-to-many port mirroring
7) IP phone automatic PoE changes
8 ) Link trunk dynamic VLAN changes
9) NTP
10) Ping source address
11) SFTP
12) SSH client and SSH RSA authentication

Otherwise if you have a specific question, I'll be happy to try and answer it.

That's great news..

It's about time Nortel/Avaya came onto the PoE+ and SFP+ markets...

Kind regards,

I'm hoping that the stacking of the new ERS 4800's together with the older ERS 4500's works seamlessly and that we're not going to see comparable issues as with a hybrid 5500/5600 stack for example. Although if the used tech/code is similar enough this won't happen probably.

Where as the 5600's run their stacking at a higher speed than 5500's, the 4500 and 4800 series all run the same stacking speed (40Gb/sec) and use the same code when they come out (v5.6).  So it looks like we have a good chance of them working together well.

Remember that the 4000 series runs 1/2 the speed of the 5500.  Each uplink/downlink cascade cable runs at 72Gb(56xx), 40Gb(55xx), 20Gb(4xxx).  Also the switch fabric speed is commensurate.

When upgrading a stack of 5500's to include a 5600 you need to:

1)  Configure the 5600 first as a non-base
2)  Configure the 5600 to be in Hybrid mode (this changes the cascade cable speed from 72 to 40)
3)  Add the 5600 to the existing 5500 stack (this allows the switch to join the stack and be learned)
4)  Take a smoke break (5 minutes max) while the base switch learns the new switch
5)  Change the 5500's base switch's BASE SWITCH to non-base
6)  Change the 5600's BASE SWITCH to base
7)  through console/gui/etc electronically tell the 5600 to become base

optionally
8)  Add additional 5000 switches to the stack.

The 5600's should be grouped together, then the 5500's. 
If you have more than 1 5600 in a hybrid stack, Switch #1 (base) and Switch #2 (backup to base) must be 5600's.  The thought process is that if the base dies, we want another 5600 to take over as base.

Cheers, Uncle John.

Any idea if the new code will support IGMP v3?

Thanks.

IGMP v3 is not specifically mentioned in the info I have, but I won't really know until I see the official release notes.  In theory the v5.6 code for the 4000 series switches should come out next month sometime.

Do you know when will it avail on the market and is it compareable to 5500 switch?
