Dell Force10 Z9000 - Isis Circuit-Type; Isis Csnp-Interval

isis circuit-type
Configure the adjacency type on interfaces.
E-Series, S4810
Syntax
isis circuit-type {level-1 | level-1-2 | level-2-only}
To return to the default values, use the no isis circuit-type command.
Parameters
level-1 You can form a Level 1 adjacency if there is at least one common
area address between this system and neighbors. You cannot form
Level 2 adjacencies on this interface.
level-1-2 You can form a Level 1 and Level 2 adjacencies when the neighbor is
also configured as Level-1-2 and there is at least one common area, if
not, a Level 2 adjacency is established. This is the default.
level-2-only You can form a Level 2 adjacencies when other Level 2 or Level 1-2
routers and their interfaces are configured for Level 1-2 or Level 2.
Level 1 adjacencies cannot be established on this interface.
Defaults level-1-2
Command Modes INTERFACE
Command History
Version 8.3.12.0 Introduced on the S4810.
Usage
Information
Because the default establishes Level 1 and Level 2 adjacencies, you do not need to configure
this command. Routers in an IS-IS system must be configured as a Level 1-only, Level 1-2, or
Level 2-only system.
Only configure interfaces as Level 1 or Level 2 on routers that are between areas (for example,
a Level 1-2 router) to prevent the software from sending unused hello packets and wasting
bandwidth.
isis csnp-interval
Configure the IS-IS complete sequence number PDU (CSNP) interval on an interface.
E-Series, S4810
Syntax
isis csnp-interval seconds [level-1 | level-2]
To return to the default values, use the no isis csnp-interval [seconds]
[level-1 | level-2] command.
