vRtrLdpNgSessionStateChange

SNMP notification prefix and OID

TIMETRA-LDP-NG-MIB.tmnxLdpNgNotifications.6

Default severity

minor

Message format string

Session state is $vRtrLdpNgSessState$. Overload Notification message is $vRtrLdpNgSessOverloadDirection$ to/from peer $vRtrLdpNgPeerLdpId$ with overload state $vRtrLdpNgSessOverloadState$ for fec type $vRtrLdpNgSessOverloadFecType$ and sub type fec $vRtrLdpNgSessOvldFecTypeSubTyp$

Cause

The vRtrLdpNgSessionStateChange notification is generated when the LDP Overload Notification message is sent to or received from the peer vRtrLdpNgPeerLdpId for the combination of vRtrLdpNgSessOverloadFecType and vRtrLdpNgSessOvldFecTypeSubTyp while vRtrLdpNgSessState remains 'operational'.

Effect

Once the Local LSR has sent the LDP Overload Notification message to the peer vRtrLdpNgPeerLdpId for fec and sub type fec indicated by vRtrLdpNgSessOverloadFecType and vRtrLdpNgSessOvldFecTypeSubTyp and vRtrLdpNgSessOverloadState has the value of 'true', then new Label Mapping Messages received for this peer for the given combination of fec and sub type fec is returned with a Label Release Message. If the Local LSR has received an LDP Overload Notification message from the peer vRtrLdpNgPeerLdpId for fec and sub type fec indicated by vRtrLdpNgSessOverloadFecType and vRtrLdpNgSessOvldFecTypeSubTyp and vRtrLdpNgSessOverloadState has the value of 'true', no new Label Mapping Message for the given combination of fec and sub type fec will be sent to this peer. If the Local LSR has received an LDP Overload Notification message from the peer vRtrLdpNgPeerLdpId for fec and sub type fec indicated by vRtrLdpNgSessOverloadFecType and vRtrLdpNgSessOvldFecTypeSubTyp and vRtrLdpNgSessOverloadState has the value of 'false', then the Local LSR will send all pending and any new Label Mapping Message for the given combination of fec and sub type fec to this peer.

Recovery

In case the Local LSR sent the LDP Overload Notification message to the peer vRtrLdpNgPeerLdpId and vRtrLdpNgSessOverloadState has the value of 'true' for fec and sub type fec indicated by vRtrLdpNgSessOverloadFecType and vRtrLdpNgSessOvldFecTypeSubTyp, then appropriate LDP configuration changes may be required on the Local and/or Remote LSR. Once the Local LSR is not overloaded anymore, an LDP Overload Notification message is sent to the peer vRtrLdpNgPeerLdpId and vRtrLdpNgSessOverloadState has the value of 'false' for given fec and sub type fec.

Event name

vRtrLdpNgSessMaxFecLimitReached

SNMP notification prefix and OID

TIMETRA-LDP-NG-MIB.tmnxLdpNgNotifications.8

Default severity

major

Message format string

Number of FECs received from the peer $vRtrLdpNgPeerAddress$ has reached the maximum value of $vRtrLdpNgSessParamMaxFec$. The current operational threshold is $vRtrLdpNgSessOperMaxFecThreshold$ percent.

Cause

A vRtrLdpNgSessMaxFecLimitReached notification is generated when the number of FEC's accepted from the peer has reached the value specified by vRtrLdpNgSessParamMaxFec. If the current number of FEC's go below the limit but higher than the configured threshold and again start to increase and hit the limit a second time, we will raise a trap if 2 or more minutes have elapsed since the first vRtrLdpNgSessMaxFecLimitReached trap was sent. If any parameter in FEC limit configuration changes and the current number of FEC's are equal to or higher than the limit specified by vRtrLdpPeerMaxFec, then we would always raise the vRtrLdpNgSessMaxFecLimitReached trap.

Effect

When the number of FECs exceed the configured maximum (vRtrLdpNgSessParamMaxFec) it results in any of the following: (1) If vRtrLdpNgSessParamMaxFecLogOnly is set to 'false' and LSR Overload Capability is supported, then Overload procedure will take place. (2) If vRtrLdpNgSessParamMaxFecLogOnly is set to 'false' and LSR Overload Capability is not supported, Label Mapping Message will be returned with Label Release Message. (3) If vRtrLdpNgSessParamMaxFecLogOnly is set to 'true', no action will be taken.

Recovery

Appropriate Configuration changes in local or peer LSR will be required.

Event name

SNMP notification prefix and OID

TIMETRA-LDP-NG-MIB.tmnxLdpNgNotifications.7

Default severity

warning

Message format string

Number of FECs received from the peer $vRtrLdpNgPeerAddress$ has gone $vRtrLdpNgSessOperThresLevel$ the configured threshold of the maximum value $vRtrLdpNgSessParamMaxFec$. The current operational threshold is $vRtrLdpNgSessOperMaxFecThreshold$ percent.

Cause

A vRtrLdpNgSessMaxFecThresChanged notification is generated when the number of FECs accepted from the peer has exceeded or drops below vRtrLdpNgSessOperMaxFecThreshold percent of the value specified by vRtrLdpNgSessParamMaxFec. New notification will not be generated if multiple internal event change occurs for the same level indicated by vRtrLdpNgSessOperThresLevel during a 2 minute interval. If any parameter in FEC limit configuration changes then we would always raise this trap if current number of FEC's are above the configured threshold or has crossed the threshold downwards. If we remain on or below the configured threshold before and after the configuration changes then no trap would be generated.

Effect

No direct effect but if the peer LSR continues to send further Label Mapping Message, then the number of FECs may exceed the configured maximum (vRtrLdpNgSessParamMaxFec) resulting in the generation of vRtrLdpNgSessMaxFecLimitReached notification.

Recovery

Appropriate Configuration changes in local or peer LSR will be required.

Targeted peer state changed - vRtrID: $vRtrID$, $vRtrLdpNgPeerAddress$, administrative state: $vRtrLdpNgTargPeerAdminState$, operational state: $vRtrLdpNgTargPeerOperState$

Cause

The vRtrLdpNgTargPeerStateChange notification is generated when the LDP peer changes state either administratively or operationally.

Effect

Based on the vRtrLdpNgTargPeerOperDownReason reason code, the system may not be able to accept new requests from this peer.

Recovery

Based on the vRtrLdpNgTargPeerOperDownReason reason code, appropriate configuration changes in LDP may be required.
