Cisco NCS 5500 Series

• Hello padding applies to only this interface and not to all interfaces.
Step 6 hello-interval seconds [ level { 1 | 2 }]
Example:
RP/0/RP0/CPU0:router(config-isis-if)#hello-interval 6
Specifies the length of time between hello packets that the software sends.
Step 7 hello-multiplier multiplier [ level { 1 | 2 }]
Example:
RP/0/RP0/CPU0:router(config-isis-if)# hello-multiplier 10
Specifies the number of IS-IS hello packets a neighbor must miss before the router should declare the adjacency as
down.
• A higher value increases the networks tolerance for dropped packets, but also may increase the amount of time
required to detect the failure of an adjacent router.
• Conversely, not detecting the failure of an adjacent router can result in greater packet loss.
Step 8 h ello-password { hmac-md5 | text } { clear | encrypted } password [ level { 1 | 2 }] [ send-only ]
Example:
RP/0/RP0/CPU0:router(config-isis-if)# hello-password text clear mypassword
Specifies that this system include authentication in the hello packets and requires successful authentication of the hello
packet from the neighbor to establish an adjacency.
Step 9 commit
Step 10 show isis [ instance instance-id ] adjacency t ype interface- path-id ] [ detail ] [ systemid system-id ]
Example:
RP/0/RP0/CPU0:router# show isis instance isp adjacency
(Optional) Displays IS-IS adjacencies.
Step 11 show isis adjacency-log
Example:
RP/0/RP0/CPU0:router# show isis adjacency-log
(Optional) Displays a log of the most recent adjacency state transitions.
Step 12 show isis [ instance instance-id ] interface [ type interface-path-id ] [ brief | detail ] [ level { 1 | 2 }]
Example:
RP/0/RP0/CPU0:router# show isis interface HundredGigE 0/1/0/1 brief
(Optional) Displays information about the IS-IS interface.
