Cause	The tIPsecRuTnlEncapIpMtuTooSmall notification is generated when the addition of tunnel encapsulation to a packet at or near the IPsec remote user tunnel's configured IP MTU may cause it to exceed the tunnel's configured encapsulated IP MTU.
Effect	The pre-encapsulated packet may be fragmented, and will require reassembly by the tunnel remote endpoint, causing a performance impact.
Recovery	Configured IP MTU and/or encapsulated IP MTU may need to be changed depending on the size of the encapsulation overhead as indicated in 'tIPsecNotifEncapOverhead', and the transmission capabilities of the tunnel's transport network.

Cause	The tIPsecTunnelEncapIpMtuTooSmall notification is generated when the addition of tunnel encapsulation to a packet at or near the IPsec static tunnel's configured IP MTU may cause it to exceed the tunnel's configured encapsulated IP MTU.
Effect	The pre-encapsulated packet may be fragmented, and will require reassembly by the tunnel remote endpoint, causing a performance impact.

tmnxIPsecGWOperStateChange

Table 10. tmnxIPsecGWOperStateChange properties
Property name	Value
Application name	IPSEC
Event ID	2012
Event name	tmnxIPsecGWOperStateChange
SNMP notification prefix and OID	TIMETRA-IPSEC-MIB.tmnxIPsecNotifications.12
Default severity	minor
Source stream	main
Message format string	Operational state change for IPsec Gateway $tmnxIPsecGWName$ on service $svcId$ and SAP $sapEncapValue$, admin state: $tmnxIPsecGWAdminState$, oper state: $tmnxIPsecGWOperState$, oper flags: $tmnxIPsecGWOperFlags$
Cause	The tmnxIPsecGWOperStateChange notification is generated when there is a state change in tmnxIPsecGWOperState for an IPsec gateway.
Effect	When the value of tmnxIPsecGWOperState is 'outOfService (3)', the IPsec gateway is operationally down and it is not ready to negotiate IKE sessions with remote clients. When the value of tmnxIPsecGWOperState is 'inService (2)', the IPsec gateway is operationally up. When the value of tmnxIPsecGWOperState is 'limited (5)', the IPsec gateway is not fully operationally up due to the conditions indicated in tmnxIPsecTunnelOperFlags and can only negotiate limited new IKE sessions.
Recovery	Please refer to tmnxIPsecGWOperFlags for information on why the gateway is operationally down.

tmnxIPsecTunnelOperStateChange

Table 11. tmnxIPsecTunnelOperStateChange properties
Property name	Value
Application name	IPSEC
Event ID	2011
Event name	tmnxIPsecTunnelOperStateChange
SNMP notification prefix and OID	TIMETRA-IPSEC-MIB.tmnxIPsecNotifications.11
Default severity	minor
Source stream	main
Message format string	Operational state change for IPsec Tunnel $tmnxIPsecTunnelName$ on service $svcId$ and SAP $sapEncapValue$, admin state: $tmnxIPsecTunnelAdminState$, oper state: $tmnxIPsecTunnelOperState$, oper flags: $tmnxIPsecTunnelOperFlags$
Cause	The tmnxIPsecTunnelOperStateChange notification is generated when there is a change in tmnxIPsecTunnelOperState for an IPsec tunnel.
Effect	When the value of tmnxIPsecTunnelOperState is 'outOfService (3)', the IPsec tunnel is operationally down and traffic arriving at the tunnel endpoints will not be encapsulated and transported. When the value of tmnxIPsecTunnelOperState is 'inService (2)', the IPsec tunnel is operationally up. When the value of tmnxIPsecGWOperState is 'limited (5)', the IPsec tunnel is operationally up but may not be ready to re-establish the connection until the conditions indicated in the tmnxIPsecTunnelOperFlags are cleared.
Recovery	Please refer to tmnxIPsecTunnelOperFlags for information on why the tunnel is operationally down.

tmnxSecNotifCmptedCertChnChngd

Table 12. tmnxSecNotifCmptedCertChnChngd properties
Property name	Value
Application name	IPSEC
Event ID	2009
Event name	tmnxSecNotifCmptedCertChnChngd
SNMP notification prefix and OID	TIMETRA-IPSEC-MIB.tmnxIPsecNotifications.9
Default severity	minor
Source stream	security
Message format string	Certificate chain changed to $tIPsecNotifCaProfNames$ in cert-profile $tIPsecNotifCertProfileName$ entry $tIPsecNotifCertProfEntryId$
Cause	The tmnxSecNotifCmptedCertChnChngd notification is generated when a computed certificate chain is changed due to a dependent CA profile being changed and brought into service.
Effect	The hash of the recomputed certificate chain, if changed, will be used for choosing cert-profile entry during new IPsec tunnel establishment.
Recovery	If the changed CA certificate is used as a trust-anchor at the peer, then the certificate should be updated at the peer as well to ensure correct cert-profile entry selection.

Property name	Value
Application name	IPSEC
Event ID	2008

Default severity	minor
Source stream	security
Message format string	Hash of certificate chain changed in cert-profile $tIPsecNotifCertProfileName$ entry $tIPsecNotifCertProfEntryId$ due to CA profile $tIPsecNotifCaProfNames$
Cause	The tmnxSecNotifCmptedCertHashChngd notification is generated when the hash of a certificate chain is changed.
Effect	The hash of the recomputed certificate chain will be used for choosing cert-profile entry during new IPsec tunnel establishment.
Recovery	If the changed CA certificate is used as a trust-anchor at the peer, then the certificate should be updated at the peer as well to ensure correct cert-profile entry selection.

tmnxSecNotifSendChnNotInCmptChn

Table 14. tmnxSecNotifSendChnNotInCmptChn properties
Property name	Value
Application name	IPSEC
Event ID	2010
Event name	tmnxSecNotifSendChnNotInCmptChn

Default severity	minor
Source stream	security
Message format string	Send-chain CA profile $tIPsecNotifCaProfNames$ not in the computed certificate chain of cert-profile $tIPsecNotifCertProfileName$ entry $tIPsecNotifCertProfEntryId$
Cause	The tmnxSecNotifSendChnNotInCmptChn notification is generated when a CA profile not belonging to the computed certificate chain is added to the send-chain of a cert-profile entry, or the certificate chain is changed such that a CA-profile in the send-chain is no longer a member of the chain.
Effect	The CA certificate(s) to be sent to the peer is not a member of the certificate chain that is requested by the peer for new IPsec tunnel establishment.
Recovery	Replace the send-chain CA profile that is not in the certificate chain with one that is.
