Hi Gobinath,

Input queue and interface buffers are a software-based router concepts.  All IOS-XR platforms have a distributed HW-forwarding based architecture so those structures don't really apply here.  Problems like buffer leak and input queue wedged are practically unseen in IOS-XR thanks to other protection mechanisms (built in policers, LPTS, ...).  Which information are you trying to get from thse values ?

Thanks Maxime,

Actually i wanted to get the queue limitation related to SPD ( BGP /ARP  / IPv6)

I think following command gives the answer but ipv6 related stats are missing , I'm seeing quite a number of IPv6
