Command Line Reference Guide

second_wait_inte
rval seconds
(OPTIONAL) Enter the wait interval, in seconds, between the first and
second LSP generation. The range is 0 to 120 seconds. The default is
5 seconds.
Defaults Refer to Parameters.
Command Modes ROUTER ISIS
Command History
Version 9.0(1.3) Introduced on the S5000.
Usage
Information
LSP throttling slows down the frequency at which LSPs are generated during network
instability. Even though throttling LSP generations slows down network convergence, no
throttling can result in a network not functioning as expected. If network topology is unstable,
throttling slows down the scheduling of LSP generations until the topology regains its stability.
The first generation is controlled by the initial wait interval and the second generation is
controlled by the second wait interval. Each subsequent wait interval is twice as long as the
previous one until the wait interval reaches the maximum wait time specified (interval
seconds). After the network calms down and there are no triggers for two times the
maximum interval, fast behavior is restored (the initial wait time).
lsp-mtu
Set the maximum transmission unit (MTU) of IS-IS link-state packets (LSPs). This command only limits the size of LSPs
generated by this router.
S5000
Syntax
lsp-mtu size
To return to the default values, use the no lsp-mtu command.
Parameters
size The maximum LSP size, in bytes. The range is 128 to 1497 for Non-
Jumbo mode and 128 to 9195 for Jumbo mode. The default is 1497.
Defaults 1497 bytes.
Command Modes ROUTER ISIS
Command History
Version 9.0(1.3) Introduced on the S5000.
Usage
Information
The link MTU and the LSP MTU size must be the same.
Because each device can generate a maximum of 255 LSPs, consider carefully whether you
should configure the lsp-mtu command.
