Issue

Simultaneous vifmgr.portdown alerts are sent from the e0f port on both HA nodes.

#02 notificationTrap <DC=[alert-server] HOST=[node-01.company.com.local] IPADDRESS=[10.123.45.12] TAG_Resource=[95bxxxxxxxxxxxxxxxxxxxxxxxxxxx22] xSLAkey=[notificationTrap] TAG_Ifdesc=[]>
[ productTrapData.0 = vifmgr.portdown:A link down event was received on node node-01, port e0f. productSerialNum.0 = 1-80-000011, [DC=alert-server]]

#02 notificationTrap <DC=[alert-server] HOST=[node-02.company.com.local] IPADDRESS=[10.123.45.13] TAG_Resource=[827xxxxxxxxxxxxxxxxxxxxxxxxxxxea] xSLAkey=[notificationTrap] TAG_Ifdesc=[]>
[ productTrapData.0 = vifmgr.portdown:A link down event was received on node node-02, port e0f. productSerialNum.0 = 1-80-000011, [DC=alert-server]]

According to EMS logs, on 2025/11/29 23:00:12, both HA nodes (node-01 and node-02) experienced a simultaneous link down event on port e0f and ports recovered at 2025/11/30 00:57.

node-01:

Sat Nov 29 23:00:12 +0000 [node-01: kernel: netif.linkDown:info]: Ethernet e0f: Link down, check cable.
Sat Nov 29 23:00:12 +0000 [node-01: intr: net.ifgrp.lacp.link.inactive:error]: ifgrp a0b, port e0f has transitioned to an inactive state. The interface group is in a degraded state.
Sat Nov 29 23:00:12 +0000 [node-01: vifmgr: vifmgr.portdown:notice]: A link down event was received on node node-01, port e0f.

Sun Nov 30 00:56:14 +0000 [node-01: kernel: netif.linkUp:info]: Ethernet e0f: Link up.
Sun Nov 30 00:56:14 +0000 [node-01: vifmgr: vifmgr.portup:notice]: A link up event was received on node node-01, port e0f.
Sun Nov 30 00:57:18 +0000 [node-01: intr: net.ifgrp.lacp.link.active:notice]: ifgrp a0b, port e0f has transitioned to the active state.
Sun Nov 30 00:57:24 +0000 [node-01: vifmgr: vifmgr.reach.unassn:notice]: Network port e0f on node node-01 is not assigned to any broadcast domain. No broadcast domains appear to be reachable from this port.

node-02:

Sat Nov 29 23:00:12 +0000 [node-02: kernel: netif.linkDown:info]: Ethernet e0f: Link down, check cable.
Sat Nov 29 23:00:12 +0000 [node-02: intr: net.ifgrp.lacp.link.inactive:error]: ifgrp a0b, port e0f has transitioned to an inactive state. The interface group is in a degraded state.
Sat Nov 29 23:00:12 +0000 [node-02: vifmgr: vifmgr.portdown:notice]: A link down event was received on node node-02, port e0f.

Sun Nov 30 00:56:14 +0000 [node-02: kernel: netif.linkUp:info]: Ethernet e0f: Link up.
Sun Nov 30 00:56:14 +0000 [node-02: vifmgr: vifmgr.portup:notice]: A link up event was received on node node-02, port e0f.
Sun Nov 30 00:57:19 +0000 [node-02: intr: net.ifgrp.lacp.link.active:notice]: ifgrp a0b, port e0f has transitioned to the active state.
Sun Nov 30 00:57:28 +0000 [node-02: vifmgr: vifmgr.reach.unassn:notice]: Network port e0f on node node-02 is not assigned to any broadcast domain. No broadcast domains appear to be reachable from this port.

The interface group ifgrp a0b is configured using physical ports e0f and e0h.
After the link up event, the state transitions from degraded to active as expected.
IFSTAT-A output indicates no errors or packet drops on port e0f.
DEVICE-DISCOVERY.XML confirms that both HA nodes' e0f ports are connected to the same switch.
