isisCircLevelType

Module: ISIS-MIB

OID (symbolic): ISIS-MIB::isisCircLevelType

OID (numeric): 1.3.6.1.2.1.138.1.3.2.1.7

Node type: OBJECT-TYPE

Type: IsisLevel

Access: read-create

Description: Indicates which type of packets will be sent and accepted on this circuit. The values set will be saved, but the values used will be modified by the settings of isisSysLevelType. Thus, if the isisSysTpe is level2 and the isisCircLevelType for a circuit is level1, the circuit will not send or receive IS-IS packets. This object follows the ReplaceOnlyWhileDisabled behavior.

What is isisCircLevelType?

Sets which packet levels (L1, L2, or both) this circuit sends and accepts, though the effective behavior is also constrained by the router-wide isisSysLevelType -- e.g. a Level-2-only router won't send/receive IS-IS packets on a circuit set to Level 1 even if configured that way here.
