Hi all,
I've got a 2610 switch.
I need to connect the gigabit ports to two aggregation switch (for redundancy).
Actually I haven't that switches.

I'm looking at pair 2810 or 2824 but I don't know if I can aggregate (LACP or something similar) the two ports on 2610 to the two 2810 switches having a 2gbps aggregated bandwidth and redundancy.

Actually my network topology is like this:

2 42U rack with 20 servers inside each one.
1 2610 (24 ports) for each rack.

I need to connect the 2610 of each rack to the two aggregation switches.

Is possible to aggregate the two ports?
Or i can only use one link?
RSTP will protect from loops.

hi
yes you can create two core 2800 whit one 2610 switch trunk and rstp config
two core switch you create one port trunk port and assing trunk number 1(trk1)

and adge switch to create 2 gigabit port configure for trunk (trk1 group) after attach all trunk group and enable stp
after create this config edge switch 2Gbps connect to core and full redundancy

good luck..

for example

Running configuration:

; J4900B Configuration Editor; Created on release #H.10.38

xxxfrist core switchxxx
hostname "ProCurve Switch 2626"
interface 10
no lacp
exit
trunk 10 Trk1 Trunk
snmp-server community "public" Unrestricted
vlan 1
name "DEFAULT_VLAN"
untagged 1-9,11-26,Trk1
ip address dhcp-bootp
exit
spanning-tree Trk1 priority 4

ProCurve Switch 2626(config)#

xxxsecond core switchxxx
hostname "ProCurve Switch 2626"
interface 10
no lacp
exit
trunk 10 Trk1 Trunk
snmp-server community "public" Unrestricted
vlan 1
name "DEFAULT_VLAN"
untagged 1-9,11-26,Trk1
ip address dhcp-bootp
exit
spanning-tree Trk1 priority 4

ProCurve Switch 2626(config)#


xxx edge switch configxxx
Running configuration:

; J4900B Configuration Editor; Created on release #H.10.38

hostname "ProCurve Switch 2626"
interface 10-11
no lacp
exit
trunk 10-11 Trk1 Trunk
snmp-server community "public" Unrestricted
vlan 1
name "DEFAULT_VLAN"
untagged 1-9,12-26,Trk1
ip address dhcp-bootp
exit
spanning-tree Trk1 priority 4

ProCurve Switch 2626(config)#

Doing so I connect one 2626 to one 2810 with a trunk. Link are redundant, but core (2810) aren't.

I need to connect port 23 on 2610 to port 1 on 2810, and port 24 on 2610 to port 1 on the second 2810.

RSTP over all.

Doing so I'll have redundant link and redundant 2810, but active will be only one link per time and max bandwidth will be 1gbit.

I would like to have 2gbit of aggregated bandwidth making an LACP trunk on port 23 and 24.

Is possibile to aggregate port 23 and 24 that are connected to two differente switch?

In cisco I can do so by staking switches.

hi
you say
Is possibile to aggregate port 23 and 24 that are connected to two differente switch?

YESS please you carefully above my config
my egge switch connect two different core switch on port 19-20 and successfully different two switch trunk connection under stp application and not blocking stp port any device

You need support for split-trunking which ProCurve switches do not support.

The best you can do is use MSTP to load-balance different VLANs on your different upliinks.

cenk sasmaztin said that he did it using simple trunking (no lacp but trunk with no protocol)

I can't see cenk's hack working. If you can manage to fool spanning tree into keeping all 3 links active simultaneously, you've just made a loop.

So it isn't possibile to trunk ports 23 and 24 on 2610 to port 1 of one 2810 and port 1 of another 2810?

That's very bad....

On reflection, maybe it would work better than I suggested in my last post. I still don't think it's a great idea though.

Matt is the guru round here, so I would definitely take his advice seriously. If you could split the carriers onto 2 different VLANs, you could have both the 2610 links active, on different VLANs.

Thanks Richard.

Looking at the original post again, there doesn't appear to be a link between the 2810's so in theory we have a loop free topology, but what's happening on the carrier end? Where is the default gateway?

Just to re-iterate though, you currently cannot configure a link aggregated group (trunk) that goes from one switch to two different switches.

hi Allessandro

you can take 3 switch and to make test my config

I need to trunk 2610 to two 2810 like this setup.

Is possibile?

yes you working truk

however two 2810 switch above router 1 connections you make enable stp protocol router and switchs some line blok stp
you omit enable stp, loop occur on network.

this loop occur not concarned truk config and you omit enable stp all producer switch ,router to face loop if you enable stp block some link block.

I think you network topology incorrect
because you make select products for your topology faulty.

2810 only L2 switch not to be on routing protocol ,all port 10/100/1000 and jumbo freme supported this switch edge switch

2610 only 2 or 4 port (2extension minigbic,2copper) port 1000Mbps other all ports 10/100 Mbps this switch edge switch
include static routing and acl.

as for me... frist you do think your network goals and you want what type redundancy network.
please you say me your network goal ,I say true product and topology.

Router will have active/standby ethernet connected to each 2810 switches so there isn't loop.

Then, I will connect port 23 (gigabit) of one 2610 to port 1 (gigabit) on the first 2810.

Then I'll connect port 24 (gigabit) of the second 2610 to port 1 (giga) of the another 2810.

On 2610 I'll make a trunk between port 23 and 24 so there aren't loops.

What's wrong with this?

hi you say router port active/standby not occur loop for me no problem.

you send me your network layout anyway not occur loop between 2810 and 2610

and please see my above config sh stp print

ProCurve Switch 2626(config)#


please check my config on network
you see not occur loops and you carefully look 2610 int 23 and 24 agregate port new interface on 2610 trk1 and speed 2Gbps


my propose
ProCurve different redundancy architecture
for example hp mesh protocol include 3400,3500,5300,5400 etc.product familiy
this protocol supply full L2 active very strong redundancy
please read my site this protocol information
http://cenksasmaztin.tr.gg/Hp-mesh-.htm

good luck..

Hi

3 Comments i want to add:

1- Concerning the last Topology file you've attached, the link between 2610 and both 2810 are called UPLINKS, and only Cisco called it Trunk (carry all the Vlans).

2- I'm with Matt, if you want to achieve Loop Free Topology + Load Balancing + Redundancy, then you must use MSTP with at least 2 Instances.

3- With such Topology, you have a single point of failure on the 2610, because if this 2610 failed then all the servers will be down.

Since you have a 2610 in each RACK, then i suggest you SOMEHOW manage to get from each server 2 links, one to first 2610, and the other one to the 2610 in the other rack.

Good Luck !!!

If you want to say:

Thanks, Merci , Grazie , Dank , ã ã ã ã ¨ã ,
æ è°¢ , Gracias , Agradecimentos , Ð±Ð»Ð°Ð³Ð¾Ð´Ð°Ñ Ñ , ش٠را .............................................


Then assign points to ALL who spent TIME on your post(s) to find a solution or help.

Good Luck !!!

I've redone the topology.
I can't change the 2610 switches because already bought.


Servers wille be connected via an active/passive link (two ethernet per server)

I like to connect the two gigabit ports on 2610 to one port of each 2810 switch.

I can do it by simply enable rstp. I'll have redundancy but i'll not have bandwidth aggregation.

One solution is to put two minigbic cat5 on each 2610, then trunk port 23-24 and connect it to one 2810, and trunk port 25-26 and connect it to the other 2810.

I'll have bandwidth aggregation e redundancy.

Actually I prefer to skip buy minigbic.
Is possibile to trunk port 23 and 24 and splitting it on the 2810?

Teorically is possibile:

on 2610 I'll make a trunk between port 23 and 24 and on the 2810 i'll make a trunk with port 1.

It should go in degraded mode on the 2810 but in full mode on 2610....

Any idea?

I've seen switch meshing, but I need to change all switches (also the 2610) and actually I can't.
More over, switches with meshing capability are out of our budget.
At the moment, cheaper switch is 4200 family but chassis only is more expensive than two 2610 and I need to buy also some modules to put inside.


So:

- or I use switch meshing (4200 for distribution, 3500 for core/aggregation) but we are out of budget

- or I put two minigbic inside each 2610 but will go out of budget very soon if we do so.

- or I'll find the way to aggregate the two gigabit port on 2610 to do redundancy and 2gbit link.

The last way is the only one that will be accepted by our boss.

:)

Sorry for my english.

Hi

- I believe both 2610 and 2810 don't support Switch Meshing feature.
- With the Topology you've attached, you get 99 marks (one mark missing).
- The last mark is to create a Trunk of 2 Links between the 2810s, and now you get 100 marks :)
- Configuration wise, use MSTP not RSTP.

Attached is my suggested drawings (according to the information in this post).

Good Luck !!!

Thanks for the clear draw.
I don't understand why i need to trunk 2 ports between 2810s...

If I put port 23 on 2610 on VLAN1 and port 24 on 2610 on VLAN2, I can do MSTP having High Availability and Load Balancing (bandwidth aggregation) ?

I'm totally new to MSTP, can you post me an example configuration that will do what I like to do (HA and aggregation)?

Using MSTP is enough or I must use also rSTP?

Hi

The link between the 2810s is important, you can call is HA (high availability link).

For the MSTP configuration:

Good Luck !!!

Good Luck !!!

Thanks for the links.

I don't understand why i need the trunk between two 2810.

Ok for the HA, but if primary 2810 fails, 2610 switch redirects all traffic to the other 2810 (because I have two uplink).

I think there is no need to trunk 2810.
Can you explain me what's the role of that trunk?
