Parameters To return to the default values, use the no isis hello-interval [seconds] [level-1 | level-2] command. seconds level-1 level-2 Allows you to set the length of time between hello packet transmissions. The range is from 1 to 65535. The default is 10. (OPTIONAL) Select this value to configure the hello interval for Level 1. This value is the default. (OPTIONAL) Select this value to configure the hello interval for Level 2. Defaults seconds = 10; level-1 (if not otherwise specified) Command Modes INTERFACE Command History This guide is platform-specific.

Usage Information Related Commands Hello packets are held for a length of three times the value of the hello interval. To conserve bandwidth and CPU usage, use a high hello interval seconds. 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 declares the adjacency as down. isis hello-multiplier Specify the number of IS-IS hello packets a neighbor must miss before the router declares the adjacency down. C9000 Series Syntax Parameters isis hello-multiplier multiplier [level-1 | level-2] To return to the default values, use the no isis hello-multiplier [multiplier] [level-1 | level-2] command. multiplier level-1 level-2 Specifies an integer that sets the multiplier for the hello holding time. Never configure a hello-multiplier lower than the default (3). The range is from 3 to 1000. The default is 3. (OPTIONAL) Select this value to configure the hello multiplier independently for Level 1 adjacencies. This value is the default. (OPTONAL) Select this value to configure the hello multiplier independently for Level 2 adjacencies. Defaults multiplier = 3; level-1 (if not otherwise specified) Command Modes INTERFACE 834 Intermediate System to Intermediate System (IS-IS)
