Use undo trill timer csnp to restore the default.
Syntax

Default
The CSNP interval is 10 seconds.

Parameters
interval: Specifies the CSNP interval in the range of 1 to 600 seconds.
Usage guidelines
On a broadcast network, the DRB advertises CSNPs at the CSNP interval to perform network-wide LSDB synchronization. A CSNP records all LSP digests of the local LSDB. When an RB receives a CSNP, the RB compares the CSNP against the local LSDB to verify whether some LSPs are aged out or missing. If the CSNP has an LSP digest that the local LSDB does not have, the RB sends a PSNP packet to request the LSP information.
Configuration in Layer 2 Ethernet interface view takes effect on only the current port. Configuration in Layer 2 aggregate interface view takes effect on the current interface and its member ports. Configuration on the member port of an aggregate interface takes effect after the member port leaves the aggregation group.
Examples
# Set the CSNP interval to 15 seconds on Ten-GigabitEthernet 1/0/1.
