Configuring PPP and MLPPP
Multilink PPP and Multilink Groups
Each multilink PPP group is given a name, up to 16 characters in length. All named components of the switch configuration must have unique names, so multilink groups and VLANs cannot have identical names. See the ExtremeWare Software User Guide for more information on allowable names for named components. Components are named using the create command. Once a component is named, you do not need to use the keyword for the component (see the shortcut below).
Create the multilink group using the following command:
create multilink <groupname>
Once the multilink group is created, assign ports to it by using the following command:
config multilink <groupname> add ports <portlist>
or you can use the following shortcut:
config <groupname> add ports <portlist>
If the first port added to a multilink group is already configured for PPP, the multilink group will inherit the configuration of the first port. Any other ports added to the link will be configured to match the multilink configuration. The next section lists the configuration commands for multilink groups and single PPP links.
Once the multilink group has been configured, it is added to a VLAN so that it can pass traffic from the VLAN across the link. To add a multilink group to a VLAN, use the following command:
config vlan <vlan> add multilink <groupname>
Typically the last step in configuring a multilink group is to use the following command to enable it:
enable multilink <groupname>
Any changes to an enabled multilink group will not take effect until the the multilink group is restarted. To restart a multilkink group, use the following command:
restart multilink <groupname>
