LIF roles does clustered Data ONTAP (8.3.1P1) use to establish connections to remote servers

[arsalankhan]

What LIF roles does clustered Data ONTAP (8.3.1P1) use to establish connections to remote servers? i.e. syslog server

For example I’m forwarding syslog messages to external server from different devices. I need to create a filter.. which IP should I use to create a filter ? I have cluster management IP and a node management.

All the managemnet activities specific to a node, such as AutoSupport, SNMP traps, and log forwarding uses the node management LIF.

For example i have 10 nodes in one cluster and i am forwarding syslogs to external server... i need to add a filter for all 10 node management ips ?

Thats correct.

Cluster management LIF may not be available to a node if its out of the cluster by any means such as out of quorum etc. Still you would like to receive ems messages from that node, right?

In fact, we need the messages from unhealthy nodes rather than healthy ones to do troubleshooting. I think that's the reason why node management LIF is used for such purposes.

Thank you so much George.

i am still struggling to get an answer for one of my cluster. I have a two node cluster and syslog is forwarding logs to external server. I am successfully receiving logs from node1-node-management port but receiving syslogs of the second node from cluster management port ? Can you explain me this please ?

Why am receiving syslogs from one cluster-management port (i.e. cluster_mgmt 10.8.29.109) and one node management port (i.e. nas-10_mgmt1 10.8.29.50) ?
