how could I define fault-redundancy (ft) for a context?

Hi,

I'm opening a new one message and close the other..

So, how could I define redundancy on a context?

I've two ACE with 1 Admin context and 1 PROD context, ft config follows.

I could not configure track-interface or query-interface for vlan in a other context :

ACE3/Admin(config-ft-track-intf)# track-interface vlan 20

Error: vlan '20' does not exist!

the ft for the admin context is running well (1 out and 1 in) but not for the PROD context (both in) see at the end :

ACE3 config

ft interface vlan 1000

  ip address 10.1.1.1 255.255.255.0

  peer ip address 10.1.1.2 255.255.255.0

  no shutdown

ft peer 1

  heartbeat interval 300

  heartbeat count 10

  ft-interface vlan 1000

  query-interface vlan 10

ft group 1

  peer 1

  priority 150

  associate-context Admin

ip route 0.0.0.0 0.0.0.0 192.168.10.1

context PROD

  allocate-interface vlan 20

  allocate-interface vlan 30

ft group 2

  peer 1

  priority 150

  associate-context PROD

  inservice

how could I define fault-redundancy (ft) for a context?

Run the command and check 

ACE_5/Admin# show ft group detail           FT Group                     : 1 No. of Contexts              : 1 Configured Status            : in-service Maintenance mode             : MAINT_MODE_OFF My State                     : FSM_FT_STATE_ACTIVE  << The context on this device is active >> My Config Priority           : 110 My Net Priority              : 110 My Preempt                   : Enabled Peer State                   : FSM_FT_STATE_STANDBY << Peer device is standby >> Peer Config Priority         : 100 Peer Net Priority            : 100 Peer Preempt                 : Enabled Peer Id                      : 1 Last State Change time       : Thu Apr  2 00:00:00 2009 Running cfg sync enabled     : Enabled Running cfg sync status      : Running configuration sync has completed Startup cfg sync enabled     : Enabled Startup cfg sync status      : Running configuration sync has completed Bulk sync done for ARP: 0 Bulk sync done for LB: 0 Bulk sync done for ICM: 0

Use this command to check if hearbit is passing or not:

how could I define fault-redundancy (ft) for a context?

Hi,

Both context should be inservice on both boxes for ft to work.

for ft tracking do you have th vlan 20 configured in that context?

Hi JM,

I think that the problem is because you are trying to configure FT tracking using a VLAN that does not exists on the Admin Context:

ACE3/Admin(config-ft-track-intf)# track-interface vlan 20

Error: vlan '20' does not exist!

FT Tracking needs to be configured on each Context, this is the only FT configuration that you have to do in the  Context itself

The rest of the FT configuration is done in the Admin Context.

So if you want to track Vlan20 for the PROD Context, just changeto the Context and apply the configuration.

Re: how could I define fault-redundancy (ft) for a context?

Hi Cesar,

Thanks for your answers!

I knew that it is not possible to define FT tracking VLAN that belongs to a another Context.

But I had not thoughts to configure this FT tracking VLAN in my context.

Now, I've configured the FT tracking on context and It's running well. Thanks a lot

Last question: with the command show ft track detail I saw always Status : in-service.

How to know with FT aktiv ist?

Hi JM,

I did not understand your question, could you please elaborate a bit more.

Re: how could I define fault-redundancy (ft) for a context?

Hi Cesar,

I'd like to known how to see if my "fault-redundancy" is running?

Which command to use it to check-up that?

How to see which ACE is activ and which is STANDBY?

So, that was my question! Because the command show me that all ft are in-service but not ACTIVE or STANDBY.

Thanks and best regards,

Jerome

Re: how could I define fault-redundancy (ft) for a context?

Hi,

You can use the show ft group detail on each Context and that output will give you all the information. Including Active and Standby state.
