Symptom:
The following message is output and activation of an interface fails.
hanet: WARNING: 87500: standby interface failed. |
Corrective action:
On the network where VLAN switch exists on the transfer path monitored via standby patrol function, this error occurs if the following two circumstances take place:
1) Connecting a redundant NIC to a port of disparate VLAN identifier.
2) Connecting one of a redundant NIC or both redundant NICs to tagged member port of the switch.
The VLAN switch cannot communicate in between the ports where VLAN identifiers are disparate. Therefore, when connecting redundant NIC to disparate VLAN identifier, transmitting the monitoring frame fails between standby NIC and operation NIC, consequentially outputting 875 message. Additionally, even if VLAN identifiers are the same port and this port is set to tag member, and in the condition where the NIC does not support tag VLAN (IEE802.1Q compliance), it still fails to retrieve tag frame from the switch. Once again, transmitting the monitoring frame fails outputting 875 message. To rectify this problem, double check the VLAN configuration of the switch and make sure VLAN identifier is identical on the port connecting redundant NIC. If the NIC you are using does not support tag VLAN, set the port of the switch as non-tag member.
