Stp command, bigpipe

From NetworkCommands

A command available on most F5 BigIP platforms; used to display or modify global system (rather than interface specific) Spanning Tree Protocol (STP) settings and status.

Usage Syntax

bigpipe stp [options]

The most commonly used options are;

• show - display all current STP status
• list [all] - display basic or all STP configuration in place
• mode [stp | rstp | mstp | disable | passthru] - configure the STP mode; the default is passthru

Usage Examples

bigpipe stp mode rstp - configure rapid stp mode

bigpipe stp mode disable - disable stp

bigpipe stp show - display current stp configuration

Usage Notes

It is impossible to check whether the device this command is executed on is actually the root bridge, as the output from this command does not include the MAC address of the BigIP, only the MAC address of the root bridge. If they are the same (as they would be if the BigIP was the root) you can't tell!

Use the bigpipe vlan show command to find out what the MAC address of each VLAN on the BigIP is and if one of them matches the root bridge MAC address, the BigIP is the root.

Changes are made to and configuration is stored in local configuration file: bigip_base.conf when the bigpipe base save command is used.

Bigpipe Usage Notes

Don't forget to save your changes using the bigpipe save all command.

Note in most cases, the show keyword displays object status or statistics, the list keyword displays configuration.

The bigpipe command can be abbreviated to just b (e.g. b help instead of bigpipe help.) Alternatively, (from v9.4,) you can use the bigpipe shell to enter commands without prefixing them with bigpipe.

Where curly or normal brackets {} or () or quotes "" or exclamation mark ! are required as part of a command and you are not using the bigpipe shell, they must be proceeded with a back slash \ to prevent the bash shell from parsing them as system commands.
