From a26b556958a9fdb7ccd13fd006af43f6aa3c5220 Mon Sep 17 00:00:00 2001 From: SuvarnaMeenakshi <50386592+SuvarnaMeenakshi@users.noreply.github.com> Date: Sat, 11 Jul 2020 09:56:22 -0700 Subject: [PATCH] [Namespace] Fix interfaces counters in InterfacesMIB RFC 2863 (#141) * [InterfacesMIB]: Fix counters in InterfacesMIB for multi-asic platforms. In multi-asic platforms SAI oid is not unique across namespace/asic. Use interface index as the key instead of using SAI oid. Signed-off-by: SuvarnaMeenakshi * [Namespace]: Remove key exists check in dbs_get_all to reduce time taken. Signed-off-by: SuvarnaMeenakshi (cherry picked from commit 16f36d80d2c1b8c5205eaf972f495c03a0899abd) * Change the key used in if_id_map to support multi-asic platform. Signed-off-by: SuvarnaMeenakshi * Fix interface counters only for rfc2863. Do not run namespace unit-test for MIBs using SAI id as key. Signed-off-by: SuvarnaMeenakshi * Fix getting interface index in InterfacesMIB Signed-off-by: SuvarnaMeenakshi * Remove debug print. Signed-off-by: SuvarnaMeenakshi * Remove db connect that is not required. Signed-off-by: SuvarnaMeenakshi * Modify as per review comments. Signed-off-by: SuvarnaMeenakshi * Fix as per review comment. Add a new dict of namespace:db connector for easier access. Signed-off-by: SuvarnaMeenakshi * Fix as per review comment. Signed-off-by: SuvarnaMeenakshi * Modify based on review comment.
