Cisco NCS 5500 Series

(Optional) Configures the amount of time that the sending router waits for an acknowledgment before it considers that
the LSP was not received and subsequently resends.
RP/0/RP0/CPU0:router(config-isis-if)# retransmit-interval 60
Step 13 retransmit-throttle-interval milliseconds [ level { 1 | 2 }]
Example:
RP/0/RP0/CPU0:router(config-isis-if)# retransmit-throttle-interval 1000
(Optional) Configures the amount of time between retransmissions on each LSP on a point-to-point interface.
• This time is usually greater than or equal to the lsp-interval command time because the reason for lost LSPs may
be that a neighboring router is busy. A longer interval gives the neighbor more time to receive transmissions.
Step 14 mesh-group { number | blocked }
Example:
RP/0/RP0/CPU0:router(config-isis-if)# mesh-group blocked
(Optional) Optimizes LSP flooding in NBMA networks with highly meshed, point-to-point topologies.
• This command is appropriate only for an NBMA network with highly meshed, point-to-point topologies.
Step 15 commit
Step 16 show isis interface [ type interface-path-id | level { 1 | 2 }] [ brief ]
Example:
RP/0/RP0/CPU0:router# show isis interface HundredGigE 0/1/0/1 brief
(Optional) Displays information about the IS-IS interface.
Step 17 show isis [ instance instance-id ] database [ level { 1 | 2 }] [ detail | summary | verbose ] [ * | lsp-id ]
Example:
RP/0/RP0/CPU0:router# show isis database level 1
(Optional) Displays the IS-IS LSP database.
Step 18 show isis [ instance instance-id ] lsp-log [ level { 1 | 2 }]
Example:
RP/0/RP0/CPU0:router# show isis lsp-log
(Optional) Displays LSP log information.
Step 19 show isis database-log [ level { 1 | 2 }]
Example:
RP/0/RP0/CPU0:router# show isis database-log level 1
