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.

Parameters
interval: Specifies the Hello interval in the range of 3 to 255 seconds.
Usage guidelines
An RB advertises Hello frames at the Hello interval to maintain a TRILL adjacency. The shorter the Hello
interval, the faster the network convergence. However, a shorter Hello interval consumes more system
resources.
The adjacency holding time is obtained by multiplying the Hello interval by the Hello multiplier. The RB
advertises the adjacency holding time to neighbors through Hello frames. If a neighbor does not receive
