i want to configure enhanced Dual-active-detection with ePAgP in Cisco 9400 series Switch line card.
please find the attach pic, once i try to configure ports in line card not showing command to complete configuration.
Cisco IOS Software [Fuji], Catalyst L3 Switch Software (CAT9K_IOSXE), Version 16.9.2, RELEASE SOFTWARE (fc4) need to now this software release will support Enhanced DAD epagp.
Solved! Go to Solution.
thanks for reply,
please find the attach image, actually i create PO1 and as per Cisco VSS configuration guide :
when i try to configure DAD which cannot complete the command
Duplicated Address Detection should be configured on a separate link different from the SVL link.
The objective of DAD is to avoid a case of dual chassis active when the SVL/VSS link fails.
if Po1 is your SVL link it is correct that you cannot configure DAD over it.
by the way, other DAD methods are better choices as they do not involve a third party device like it happens with PAGP+.
Fast hellos over a dedicated direct link made of 1 GE ports is to be preferred over ePAGP in my opinion.
Hope to help
int po channel 1 i am using only for epagp dad, as i following exactly as per below document
Once i go to below command : not getting command as you can see in attach
Thank you for reply,
Yes i already configured interface as per document
i cannot find dad commands please help.
reading at page 16 of the config guide you have provided I see
This command will not be visible on the device after the configuration, but will continue to function
Try in this way on an interface that is NOT part of the SVL bundle, connect them directly.
for PAGP+ dual active detection you need a bundle with PAGP enabled on it (different from the SVL bundle) and then the commands are on page 17
In the example po1 is configured for PAGP desirable and placed in shutdown state then the following command is given
Device(config-stackwise-virtual)#dual-active detection pagp trust channel-group 1
Later the po1 interface is re-enabled with no shut.
The po1 must connected to a third party device capable of PAGP+. (a sort of L2 helper)
Anyway a direct link is a better choice for DAD. No dependency on third party devices.
Hope to help
What if you try this command under the interface?
Thank you reply,
Actual i not try below command :
because i thing above commands will support only in Supervisor engine, and i am trying to configure DAD in Line card , epagp any how tomorrow i will visit again to try command.
