Maestro 140 Uplink topology

[todd]

Hi Expert,

We just win a project to implement single site Maestro, 2 MHO-140 and 3 SG6600.

From maestro getting started guide, it shows both MHOs is connected to a single switch or a vPC switch.  But our customer environment is a dual layer2 switch and don't support vPC.

Can you help us confirmed MHO Uplink bond interface can operate in Active/Backup mode? And the topology is workable ?

Thanks!

Yes active/backup on a bond is possible.

That looks correct to me.

Thank you!

One more Question.

In the attached picture,  when one of the MHO Active uplink is down, will traffic go to the other MHO ? Am I making the right assumption ?

Todd

[the_rock · Accepted solution]

Logically yes, that would be my assumption as well.

[RickLin · Accepted solution]

Yes, it did function just as you say.

If you can want to figure out which uplink interface is active in each bond interface, you can try to use this.

[Expert@XXXXXX-ch01-01:0]# more /proc/net/bonding/bond*| grep Current
Currently Active Slave: eth2-21
Currently Active Slave: eth2-23
Currently Active Slave: eth1-25
Currently Active Slave: eth2-27
Currently Active Slave: eth2-29

eth1 is an MHO-1 uplink interface

eth2 is an MHO-2 unlink interface

Hi Rick,

Thank you!  The command is also helpful.
