Remote Sending Redundant IP Interface Unavailable
If the remote node is sending redundant IP interface unavailable, the local node will treat the local
redundant IP interface associated with the SRRP instances group IP interface as down. A Local
Redundant IP Interface Unavailable event is generated detailing the SRRP instance ID, the local
and remote system IP addresses, the local group IP interface name, the local redundant IP interface
name and the redundant IP interface IP address and mask.
Remote SRRP Advertisement SAP Non-existent
If the remote node's SRRP advertisement SAP does not exist on the local SRRP instances group
IP interface, the local node sends local receive SRRP advertisement SAP unavailable to the
remote node. An SRRP receive advertisement SAP non-existent event is generated detailing the
SRRP instance ID, the local and remote system IP addresses, the local group IP interface name
and the received remote SRRP advertisement SAP. Since SRRP advertisement messages cannot
be received, the local node will immediately become master if it has the lower system IP address.
Remote Sending Local Receive SRRP Advertisement SAP Unavailable
If the local node is receiving local receive SRRP advertisement SAP unavailable from the remote
node, an SRRP Remote Receive advertisement SAP Unavailable event will be generated detailing
the SRRP instance ID, the local and remote system IP addresses, the remote group IP interface
name and the local SRRP advertisement SAP. Since the remote node cannot receive SRRP
advertisement messages, the local node will immediately become master if it has the lower system
IP address.
Local and Remote Dual Master Detected
If the local SRRP state is master and the remote SRRP state is master, an SRRP dual master event
is generated detailing the SRRP instance ID and the local, remote system IP addresses and the
local and remote group IP interface names and port numbers.
