L2vpn Aging time on ASR9k version 4.3.x and 5.3.x

[mcagiola]

Hi all, i need to clarify one thing, the minimum aging time on l2vpn ASR9K with version 4.2.X and 5.3.X.
In the configuration guide we can read that:
Use the  seconds argument to specify the maximum age of the MAC address table entry. The range is from 120 to 1000000 seconds. Aging time is counted from the last time that the switch saw the MAC address. The default value is 300 seconds.
But in reality what i can do is :
RP/0/RSP0/CPU0:9K10-4-511-MOM(config-l2vpn-bg-bd-mac)#aging time ?  <300-30000>  MAC address aging time in seconds
So the reference guide is not correct?

The answer is, an hardware limitation.

Simply doing l2vpn capability we can see the aging time "limitations":
