lsp-gen-interval (FabricPath)

To configure a link-state packet (LSP) generation interval, use the lsp-gen-interval command. To return to the default setting, use the no form of this command.

lsp-gen-interval {lsp-max-wait | lsp-initial-wait | lsp-second-wait}

no lsp-gen-interval {lsp-max-wait | lsp-initial-wait | lsp-second-wait}

Syntax Description

lsp-max-wait

Maximum interval (in seconds) between two consecutive occurrences of an LSP being generated. The range is from 50 to 120000. The default is 8000.

lsp-initial-wait

Initial LSP generation delay (in milliseconds). The range is from 50 to 120000. The default is 50.

lsp-second-wait

Hold time between the first and second LSP generation (in milliseconds). The range is from 50 to 120000. The default is 50.


Command Default

The defaults are as follows:

•lsp-max-wait: 8000

•lsp-initial-wait: 50

•lsp-second-wait: 50

Command Modes

Usage Guidelines

You can enter the lsp-gen-interval command to control the rate of LSP packets being generated, transmitted, and retransmitted.

This command requires an Enhanced Layer 2 license.

Examples

This example shows how to configure an LSP-generation interval: 

switch# configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

switch(config)# fabricpath domain default

switch(config-fabricpath-isis)# lsp-gen-interval 9000 60 70

switch(config-fabricpath-isis)#

lsp-mtu (FabricPath)

To configure a link-state packet (LSP) maximum transmission unit (MTU) that is generated by the Cisco Nexus 5500 software, use the lsp-mtu command. To return to the default setting, use the no form of this command.

lsp-mtu bytes

no lsp-mtu bytes
