Dell Force10 TeraScale E Series - Page 837

Intermediate System to Intermediate System (IS-IS) | 837
Parameters
Defaults
seconds = 10; level-1 (if not otherwise specified)
Command Modes
INTERFACE
Usage
Information
The default values of this command are typically satisfactory transmission times for a specific interface
on a designated intermediate system. To maintain database synchronization, the designated routers
send CSNPs.
Level 1 and Level 2 CSNP intervals can be configured independently.
isis hello-interval
e
Specify the length of time between hello packets sent.
Syntax
isis hello-interval seconds [level-1 | level-2]
To return to the default values, enter the no isis hello-interval [seconds] [level-1 | level-2]
command.
Parameters
Defaults
seconds = 10; level-1 (if not otherwise specified)
Command Modes
INTERFACE
Usage
Information
Hello packets are held for a length of three times the value of the hello interval. Use a high hello
interval seconds to conserve bandwidth and CPU usage. Use a low hello interval seconds for faster
convergence (but uses more bandwidth and CPU resources).

isis hello-multiplier Specifies the number of IS-IS hello packets a neighbor must miss before the
router should declare the adjacency as down.
