VSM Configuration Commands
Generic Commands
shutdown
Syntax [no] shutdown
Context config>vsm>ccag ccag-id
Description This command controls the administrative state of the ccag-id the command is executed under. Upon
creation, the default state of a CCAG is to be administratively up which corresponds to the no
shutdown form of the command. If the CCAG must be forced to be operationally down, the
shutdown command will place the CCAG into an administratively down state causing the
operational state to also be down.
When a CCAG is shutdown, all SAPs associated with the CCAG will be operationally down. An
operationally down SAP cannot be used for forwarding packets. If the SAP is part of the VPLS
service, all MAC entries associated with the SAP will be removed from the VPLS FDB and the SAP
will be removed from the flooding domain of the VPLS. If the SAP is part of an IES service, the
associated IP interface will be set to an operationally down state. Network IP interfaces bound to a
shutdown CCAG will be operationally down as well.
Executing the no shutdown command sets the CCAG to the default up administrative state. As long as
at least one member CCA in the CCAG is active, all SAPs and network IP interfaces associated with
the CCAG will be allowed to enter the operationally up state.
Default no shutdown
description
Syntax description description-string
no description
Context config>vsm
Description This command defines an informational string associated with the CCAG. The description string may
be up to 80 characters long and contain only printable ASCII characters. Each time this command is
successfully executed, any previous description string will be overwritten. If the command fails due
to improper string definition, a previously successful description string will remain.
The no form of the command removes any current description string from the CCAG.
Default None (A description string must be explicitly defined)
Parameters description-string — Defines the string of printable ASCII characters, up to 80 characters that will be
stored and displayed as a description for the ccag-id that the description command is executed
under. The string must be entered in double quotation marks if the string contains spaces.
