Conversation
Nokia-IXR7220-H6-O256 has 256 ports and significantly more BGP sessions than other variants, resulting in higher FRR BGP memory usage. Observed steady-state usage is ~368 MB with peaks up to ~389 MB. Raise the memory_high_threshold from 384 MB to 512 MB to avoid false alarms.

Description of PR
Summary:
Cherry-pick of sonic-net/sonic-mgmt#24953 to 202512 branch.
Nokia-IXR7220-H6-O256 has 256 ports and significantly more BGP sessions than other variants, resulting in higher FRR BGP memory usage. Observed steady-state usage is ~368 MB with peaks up to ~389 MB. Raise the
memory_high_thresholdfrom 384 MB to 512 MB to avoid false alarms.Note: Applied manually (not a clean cherry-pick) because the upstream commit also included platform entries for Cisco-C8220TG and Mellanox-SN6600 which are not yet present in 202512. Only the Nokia-IXR7220 change is included here.
Type of change
Approach
What is the motivation for this PR?
The Nokia-IXR7220-H6-O256 (256-port variant) has significantly more BGP sessions than other IXR7220 variants, leading to higher steady-state FRR BGP memory (~368 MB, peaks ~389 MB). The previous threshold of 384 MB was too low and caused false alarms.
How did you do it?
Added a Nokia-IXR7220 platform entry in
memory_utilization_dependence.jsonwithmemory_high_thresholdset to 512 MB.How did you verify/test it?
Verified in sonic-net/sonic-mgmt#24953.
Any platform specific information?
Nokia-IXR7220-H6-O256 (256-port variant)
Supported testbed topology if it is a new test case?
