Ethernet Interface port on Controller is going up to down daily
Applies to
- AFF A300
- NIC II 2-Port RJ45 10GBASE-T PCIe card (P/N X1120A)
Issue
- Multiple port link down events in EMS logs. Example:
[node_name: kernel: netif.linkDown:info]: Ethernet e1a: Link down, check cable.
[node_name: intr: net.ifgrp.lacp.link.inactive:error]: ifgrp a0a, port e1a has transitioned to an inactive state. The interface group is in a degraded state.
[node_name: vifmgr: vifmgr.portdown:notice]: A link down event was received on node node_name, port e1a.
[node_name: kernel: netif.linkUp:info]: Ethernet e1a: Link up.
[node_name: vifmgr: vifmgr.portup:notice]: A link up event was received on node node_name, port e1a.
[node_name: intr: net.ifgrp.lacp.link.active:notice]: ifgrp a0a, port e1a has transitioned to the active state.
[node_name: vifmgr: vifmgr.reach.noreach:notice]: Network port e1a on node node_name cannot reach its expected broadcast domain Default:Default. No other broadcast domains appear to be reachable from this port.ifstat show an increasing amount of "up to downs" for the selected port and no other errors
- "up to down" counter increasing in the
ifstatoutput for the afected port. Example:
-- interface e1a (22 hours, 11 minutes, 36 seconds) --

LINK INFO
Speed: 0 | Duplex: full | Flowcontrol: none
Media state: no carrier | Up to downs: 135 | HW assist: 7711
- No other errors noticed in the
ifstatoutput - Issue persist after a cable replacement
- issue persist after a switch port change
- Issue persist after a patch panel port change.
