Parameter  Description 
Circuit Type 
Select the circuit type here. Options to choose from are: 
•  Level-1 - Specifies to configure the Switch for Level 1 adjacency only. 
•  Level-1-2 - Specifies to configure the Switch for Level 1 and Level 2 
adjacency. 
•  Level-2 - Specifies to configure the Switch for Level 2 adjacency only. 
Hello Padding 
Select to enable or disable the hello padding feature here. ISIS hello packets are 
padded to the full maximum transmission unit (MTU) size. Padding ISIS hello 
packets to the full MTU allows early detection of errors that resulted from 
transmission problems with large frames or errors that resulted from mismatched 
MTUs on adjacent interfaces. 
Disable the hello padding in order to avoid wasting network bandwidth in case the 
MTU of both interfaces are the same.
