vQFX10k 15.1X53-D60 3 BUGS on MC-LAG (one fatal) :(

‎02-21-2017 10:25 PM

 

  1. Parser bug for redundancy-group

 

unlike the QFX5k the vQFX10k needs the redundancy-group and redundancy-group-list setting

if omitted you get a cryptic commit error:

 

error: Failed Reading Default configuration database:

 

error: configuration check-out failed

so you need to set:

 

set protocols iccp peer <peer-ip> redundancy-group-id-list 1

 

 

and then if you have any MC-LAGs configured yet, do:

 

 

set interfaces aeX aggregated-ether-options mc-ae redundancy-group 1

 

 BUT on vQFX10k ....

 

 

{master:0}[edit]

lab@QFX53# set interfaces ae4 aggregated-ether-options mc-ae ?

Possible completions:

+ apply-groups         Groups from which to inherit configuration data

+ apply-groups-except  Don't inherit configuration data from these groups

  chassis-id           Chassis id of MC-AE network device (0..1)

  enhanced-convergence  Optimized convergence time for mcae

> events               MCAE related events

  init-delay-time      Init delay timer for mcae sm for min traffic loss

  mc-ae-id             MC-AE group id (1..65535)

  mode                 Mode of the MC-AE

  recovery-delay-time  Delay timer for bringing up ICL, ICCP (1..6000 seconds)

  revert-time          Wait interval before performing switchover (1..10 minute)

  status-control       Status of the MC-AE chassis

  switchover-mode      Switch over mode

 

 

but you can configure it: ( you have to type in the full parameter, no autofill)

 

 

lab@QFX53# show interfaces ae4

##

## inactive: interfaces ae4

##

mtu 2000;

aggregated-ether-options {

    lacp {

        passive;

        system-id 55:55:55:55:55:55;

        admin-key 4;

    }

    mc-ae {

        mc-ae-id 4;

        redundancy-group 4;

        chassis-id 0;

        mode active-active;

        status-control active;

    }

}

unit 0 {

    family ethernet-switching {

        interface-mode trunk;

        vlan {

            members [ V100 V150 V200 V250 ];

        }

    }

}

 

2.BUG on show multi-chassis mc-lag configuration-consistency

 

even though the ICCP and Multi-chassis protection is oK

 

show iccp

the command does NOT show any remote information:

...

 

and the most cumbersome 3. Bug is

 

when activating the ae3 ( inactive config see above )

 

after 10 seconds all XE-interfaces are gone and are invisible !!!!

the logfile is attached

 

to get the interfaces back you need to deactivate  the mc-ae config part and then the interfaces are back

Hi alexander,

 

 

May i know whether this vQFX support VC or VCF? I'm try to make it vc / vcf but fail.

 

Thanks and appreciate your feedback

I assume this is physica 10K, vQFX, yes?

 

I do not believe configuration-check or configuration-sync is yet supported on 10K.

 

Looking into other parts.

no, vQFX is a virtual QFX  not a physical one

at least configuration-check does a local checking but not a remote one

 

there are no release informations regarding the vQFX available

and all the QFX have the nasty attitude, that you can enter or configure things which are unsupported or not working but you do not get any error or commit warnings.

 

regards

PS the other error family EVPN and family route-target together I assume is also true for the physical one as it is pure control plane (see my other post in this forum)
