Inbound packet errors warning observed after adding new nodes to the cluster on new BES switches

Applies to

• Existing cluster adding AFF A700 nodes
• Cluster Network Switch upgrade to BES-53248

Issue

• Cluster network switches replaced with BES-53248
• Cluster enlarged with new AFF-A700 nodes
• Packet loss messages in EMS on cluster ports of newly added nodes. Example: 

[?] Sat Oct 22 10:44:59 +0300 [node-02: vifmgr: vifmgr.cluscheck.ctdpktloss:alert]: Continued packet loss when pinging from cluster lif node-02_clus1 (node node-02) to cluster lif node-07_clus1 (node node-07).

[?] Sat Oct 22 10:51:28 +0300 [node-02: mgwd: callhome.hm.alert.major:alert]: Call home for Health Monitor process cshm: ClusterIfInErrorsWarn_Alert[cluster-SW2/Slot: 0 Port: 49 100G - Level].

• Health monitor alerts on cluster ports of newly added nodes. Example:

Node: node-05
Monitor: ethernet-switch
Alert ID: ClusterIfInErrorsWarn_Alert
Alerting Resource: cluster-SW1/Slot: 0 Port: 49 100G - Level
Description: The percentage of inbound packet errors of switch interface "cluster-SW1/Slot: 0 Port: 49 100G - Level" is above the warning threshold.

• Switch interface counters increasing, for impacted ports, OutDropPkts Rx and TX Errors.outputs. Example:
