This counter tracks the number of times this Intermediate System has attempted to exceed the maximum LSP sequence number. Any nonzero value is unusual and signals a potential protocol-level anomaly, since sequence number exhaustion is rare and typically indicates prolonged instability or excessive LSP regeneration. For example, an engineer investigating a rare increment in csIsisSysAttmptToExMaxSeqNums discovers this instance has been regenerating its own LSP unusually often due to a long-running local interface flap.
