Description of PR
Summary:
ARP stress test is failing for certain CISCO 8000 platforms as the tested scale exceeds the HW availablity
Fixes # (issue)
Choose ARP scale based on available NH entries for CISCO 8000 platforms
Type of change
Back port request
Approach
What is the motivation for this PR?
Pass all sonic mgmt tests on CISCO 8000 platforms
How did you do it?
Run all sonic-mgmt testcases with CISCO 8000 as DUT and verify
How did you verify/test it?
Make sure all learnt ARP's are installed by comparing the neighbor entries installed in HW with ARP requests sent
Any platform specific information?
In certain CISCO platforms, Each Neighbor needs one NH entry. As a general fix, we limit the number of Neighbor entries tested to the available NH entry on the platform
Supported testbed topology if it's a new test case?
