Parameters
service-instance
instance-id
: Specifies a service instance by its ID in the range of 1 to 32767.
ma-id
: Creates an MA.
icc-based
icc-name
: Specifies that an MA is identified by an ICC. The
icc-name
argument is a string
of 1 to 13 characters.
integer
ma-num
: Specifies that an MA is identified by an integer, where
ma-num
is in the range of 0
to 65535.
string
ma-name
: Specifies that an MA is identified by a string, where
ma-name
is string of 1 to 45
characters that can contain letters, numbers, and special characters such as tilde (~), exclamation
mark (!), at sign (@), number sign (#), dollar sign ($), percent (%), caret (^), ampersand (&),
asterisk(*), brackets ({ }, ( ),[ ], < >), hyphen (-), underscore (_), plus (+), equal sign (=), vertical bar (|),
backslash (\), colon (:), semicolon (;), quotation marks (", '), comma (,), period (.), and slash (/).
vlan-based
[
vlan-id
]: Specifies that an MA is identified by a VLAN ID, where
vlan-id
is in the range
of 1 to 4094. If you do not provide the
vlan-id
argument, the VLAN ID specified by
vlan
vlan-id
is used.
If the
vlan
vlan-id
option is not provided, you must specify the
vlan-id
argument for the
vlan-based
[
vlan-id
] option.
ma-index
index-value
: Specifies an MA index in the range of 1 to 4294967295. If this option is not
specified, the system automatically assigns the smallest index number that is not in use. As a best
practice, use the index automatically assigned by the system.
md
md-name
: Specifies the name of an MD. The
md-name
argument is a string of 1 to 43 characters
that can contain letters, numbers, and special characters such as tilde (~), exclamation mark (!), at
sign (@), number sign (#), dollar sign ($), percent (%), caret (^), ampersand (&), asterisk(*), brackets
({ }, ( ),[ ], < >), hyphen (-), underscore (_), plus (+), equal sign (=), vertical bar (|), backslash (\), colon
(:), semicolon (;), quotation marks (", ’), comma (,), period (.), and slash (/).
vlan
vlan-id
: Specifies the VLAN that the MA serves, in the range of 1 to 4094. If this option is not
provided, the MA does not serve any VLAN.
Usage guidelines
A service instance is indicated by an integer to represent an MA in an MD. The MD and MA define the
level attribute and VLAN attribute of the messages handled by the MPs in a service instance. An MA
index uniquely identifies a specific MA in an MD. An MA index can be used in different MDs.
An MD name must be in compliant with the specifications in table 21-19 in IEEE802.1ag-2007.
You must create the relevant MD and MA prior to creating a service instance with the MD name.
When you delete a service instance, you are deleting the configurations related to that service
instance as well.
Deleting a service instance not only breaks up the connection between the service instance and the
relevant MA, but also deletes the MA itself.
Examples
# Create a level-3 MD named
test_md
and create service instance 5, in which the MA is identified by
a VLAN and serves VLAN 100.
