• adjacency: the restarting router receives the remaining time value from its peer and adjusts its T3 value so if user has configuredthis option.• manual: allows you to specify a fixed value that the restarting router should use.The range is from 50 to 120 seconds.The default is 30 seconds.Examples of the show isis graceful-restart detail CommandNOTE: If this timer expires before the synchronization has completed, the restarting router sends the overload bit in the LSP.The 'overload' bit is an indication to the receiving router that database synchronization did not complete at the restarting router.To view all graceful restart-related configurations, use the show isis graceful-restart detail command in EXEC Privilegemode.Dell#show isis graceful-restart detailConfigured Timer Value======================Graceful Restart : EnabledInterval/Blackout time : 1 minT3 Timer : ManualT3 Timeout Value : 30T2 Timeout Value : 30 (level-1), 30 (level-2)T1 Timeout Value : 5, retry count: 1Adjacency wait time : 30Operational Timer Value======================Current Mode/State : Normal/RUNNINGT3 Time left : 0T2 Time left : 0 (level-1), 0 (level-2)Restart ACK rcv count : 0 (level-1), 0 (level-2)Restart Req rcv count : 0 (level-1), 0 (level-2)Suppress Adj rcv count : 0 (level-1), 0 (level-2)Restart CSNP rcv count : 0 (level-1), 0 (level-2)Database Sync count : 0 (level-1), 0 (level-2)Circuit TenGigabitEthernet 2/10:Mode: Normal L1-State:NORMAL, L2-State: NORMALL1: Send/Receive: RR:0/0, RA: 0/0, SA:0/0T1 time left: 0, retry count left:0L2: Send/Receive: RR:0/0, RA: 0/0, SA:0/0T1 time left: 0, retry count left:0Dell#Example of the show isis interface CommandTo view all interfaces configured with IS-IS routing along with the defaults, use the show isis interface command in EXEC Privilegemode.Dell#show isis interface TenGigabitEthernet 1/34TenGigabitEthernet 1/34 is up, line protocol is upMTU 1497, Encapsulation SAPRouting Protocol: IS-ISCircuit Type: Level-1-2Interface Index 0x62cc03a, Local circuit ID 1Level-1 Metric: 10, Priority: 64, Circuit ID: 0000.0000.000B.01Hello Interval: 10, Hello Multiplier: 3, CSNP Interval: 10Number of active level-1 adjacencies: 1Level-2 Metric: 10, Priority: 64, Circuit ID: 0000.0000.000B.01Hello Interval: 10, Hello Multiplier: 3, CSNP Interval: 10Number of active level-2 adjacencies: 1Next IS-IS LAN Level-1 Hello in 4 secondsNext IS-IS LAN Level-2 Hello in 6 seconds488 Intermediate System to Intermediate System
