Command Line Reference Guide

level-1 (OPTIONAL) Independently configures the interval of time between
transmission of CSNPs for Level 1.
level-2 (OPTIONAL) Independently configures the interval of time between
transmission of CSNPs for Level 2.
Defaults seconds = 10; level-1 (if not otherwise specified)
Command Modes INTERFACE
Command History
Version 9.0(1.3) Introduced on the S5000.
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.
You can configure Level 1 and Level 2 CSNP intervals independently.
isis hello-interval
Specify the length of time between hello packets sent.
S5000
Syntax
isis hello-interval seconds [level-1 | level-2]
To return to the default values, use the no isis hello-interval [seconds]
[level-1 | level-2]
command.
Parameters
seconds Allows you to set the length of time between hello packet
transmissions. The range is 1 to 65535. The default is 10.
level-1 (OPTIONAL) Select this value to configure the hello interval for Level
1. This value is the default.
level-2 (OPTIONAL) Select this value to configure the hello interval for Level
2.
Defaults seconds = 10; level-1 (if not otherwise specified)

Command History
Version 9.0(1.3) Introduced on the S5000.
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).
