Cisco ASR 9000 Series Configuration Guide

PurposeCommand or Action
Enters interface configuration mode.
interface type interface-path-id
Example:
RP/0/RSP0/CPU0:router(config-isis)# interface
GigabitEthernet 0/1/0/3
Step 4
Configures padding on IS-IS hello PDUs for an IS-IS
interface on the router.
hello-padding { disable | sometimes } [ level { 1 | 2 }]
Example:
RP/0/RSP0/CPU0:router(config-isis-if)# hello-padding
sometimes
Step 5
•
Hello padding applies to only this interface and
not to all interfaces.
Specifies the length of time between hello packets that
the software sends.
hello-interval seconds [ level { 1 | 2 }]
Example:
RP/0/RSP0/CPU0:router(config-isis-if)#hello-interval
6
Step 6
Specifies the number of IS-IS hello packets a neighbor
must miss before the router should declare the
adjacency as down.
hello-multiplier multiplier [ level { 1 | 2 }]
Example:
RP/0/RSP0/CPU0:router(config-isis-if)#
hello-multiplier 10
Step 7
•
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.
Specifies that this system include authentication in the
hello packets and requires successful authentication
h ello-password { hmac-md5 | text } { clear | encrypted
} password [ level { 1 | 2 }] [ send-only ]
Step 8
of the hello packet from the neighbor to establish an
adjacency.
Example:
RP/0/RSP0/CPU0:router(config-isis-if)# hello-password
text clear mypassword
commit
Step 9
(Optional) Displays IS-IS adjacencies.
show isis [ instance instance-id ] adjacency t ype interface-
path-id ] [ detail ] [ systemid system-id ]
Step 10
Example:
RP/0/RSP0/CPU0:router# show isis instance isp
adjacency
(Optional) Displays a log of the most recent adjacency
state transitions.
show isis adjacency-log
Example:
RP/0/RSP0/CPU0:router# show isis adjacency-log
